Test of the Real Nvidia Gtx Titan, single-sli-tri Sli, 4 WAY SLI
-
Teeh I can't lie to you, that's why I tell you that I don't know, since in the conditions that I see them they are not normal, but when I can I'll tell you, tomorrow in the morning I'll ask my colleague and I'll let you know, if I can tomorrow in the afternoon or evening I'll tell you and if not on the weekend without fail, but I would tell you that what is happening to you must be normal, that's the first thing. It's the same as in CPU, there is a lot of variety, but if I can tell you and I don't want to scare you, these GPUs are very similar to CPUs like Intel in terms of electro-migration, that's why I'm not in favor of raising the voltage. Although you also shouldn't be alarmed or scared, of course, everyone should do what they think is appropriate, but the important thing is to enjoy what you have and punto.Me I'm going to sleep and teeh I repeat, worry only about enjoying it, listen to me it's an impressive graphics card
Well I would appreciate it, to console me a little, at least…:ugly:

Pepillo dime que te parece
Well, that's correct. If you look at the graphs, the GPU clock has suffered some small peak, the consumption is already at the limit and nothing more can be done without removing that limitation from the bios. I am not a serious "overclocker". ELP3 or Jotele, for example, know much more than I do about these topics.
Well, I would appreciate it, to console me a little, at least…:ugly:
Don't worry too much and go play, it will give you something ;D

Pepillo, can you believe I haven't slept well? :ffu:Obsessive-compulsive disorders aside, is what's happening to me in Crysis 3 normal? I mean, going from 1084 to 1071 or 1058…1045...up again...like that, over and over? While in Unigine it stays stuck at 1.084 all the time?
I guess it's the throttling because of the heat, or the power consumption...¬¬
Too bad I don't have the balls to flash it and at least give it a 15% power boost...I imagine it wouldn't stutter as much...
Besides, correct me if I'm wrong, but that kind of frequency fluctuation will result in some stuttering.
And I wonder...why the hell did they put this boost nonsense in the new generations? I was so happy with the old-school overclocking...
Oh, and one last thing. Maybe my 950 at 3.6 HT on is causing a bottleneck in Crysis 3, because in some sequences, the GPU usage drops, and the frames are below 60...
I was also looking at your card, Pepillo, after you put the tuned BIOS in...curious about the power consumption, it's brutal, at 1.21 and the fan at 75%...we'll be over 275?
-
I've told you several times already, Throttling is due to power consumption, limited to 265W, which is 106% Power. The advantage of modified bios is that they allow you to increase that consumption up to 300 or more in theory (in practice, 300W is the maximum of the two power connectors of the card and the PCIe), thus eliminating Throttling, at least up to 1.202 Mhz …. more, if the card is enough, you're back to the downswings, because with 1.21 voltage and the fan at 70% you're back to the limit of consumption.
Look, this graph is after an hour of playing Crysis 3:
Stuck all the time at 1.202 Mhz, with the GPU always above 90% …..... and the consumption reached 114% (114% of the TDP of 250W are 285W) and taking into account that it measures it below, I'm already at 300W. That is, cooler than before and without downswings.

You won't have MS with a single GPU even if the frequency drops a bit, first because single GPUs perform better and you'd notice if you dropped to 600 MHz or less and that depends on the game, second because those cards have hardware MS control, the previous ones like the 480 or 580 have it by software, but they put hardware control on these thinking about boost and thinking that in SLI one can run at different frequencies, that's why with a single GPU you won't have MS or if you do it will be a driver problem or a game that doesn't run well, but normally it should run smooth.
you could also notice if for example it doesn't give more than 35 or 40 fps, but more than MS it will be that it loses fluidity, I mean, I'd play and compare with your previous SLI, I think this Titan runs better and with fewer problems, games like GTA4 should run much better.

What fjavi says is quite true. It's one thing to seek the maximum for overclocking, benchmarking, etc., and quite another for gaming. This card is designed for dynamic clocks and that doesn't have to be seen in a negative way when gaming.

At the end this morning I caught a couple of flights and at mid-morning at home, food and RL assembly.
Pepillo, mine are fresh, this image is after 6 unigine in a row.
Temperatures at idle: between 20 and 21º C.
As standard (they are SC not the normal ones) between 30 and 31ºC and they don't go beyond that.
My voltages were dropping to 1.13V, now they stay at 1.16V (all strictly standard) which I imagine they could go up more without touching the BIOS. Now I have to pick up everything that I have on the table, if I have time I can maybe try to push them up like I did last domino without touching the voltage to see if they have gained, although I suppose that if:
Well I'll pick up later.
They are impressive, also to say that the ones I brought this morning my colleague told me that with very good ones.
With offset raised to +55, without touching voltage, voltage remains stable at 1.16. You don't need to modify BIOS for these beasts, you just put RL in them and they are devils without knowledge. With the standard cooler the card I had at home at more than +55 already started to do something strange, not serious throttling but there was something strange. These with RL have solved the problem for now, without touching BIOS or raising Vcore.
More results, I hope I don't bore
Vcore without touching, offset +100, result ok
Vcore without touching offset +120= 1176Mhz superstable
Up to +130 offset they hold without touching voltage if I put +140 offset they fail, that's the limit of mine with RL without raising voltage, that is 1189mhz, according to eVGA precision. I saw these working yesterday at work and without RL they held a maximum offset of 80 without touching voltage, so the improvement with RL apart from temperatures in my case is +50. Surely if they touched voltage with eVGA precision they would reach 1200mhz, I don't know, but as I'm going to have them as standard I don't care. With what they give as standard it's enough for me.
I forgot to put a picture of my last test, they don't give more without raising Vcore and I don't want to do that

Je, Je, hubiese apostado dinero a que terminabas haciéndolo, y cuando vi que te habías dado de alta en OCN, pensé que en menos de 24h lo harías
Yo estuve a punto el otro día, pero me paró que leí que en idle, en el escritorio, no se baja el voltaje. ¿Te importa comprobar si es así? ¿Que bios has utilizado? Hay decenas de ellas …....
Tengo ganas de probarlo, la mía no necesita un offset de 200, con 175 ya pasa los 1.200 Mhz, tengo la sensación de que me tocó una buena y me da un poco de pena no exprimirla.
Saludos
Pues yo me he lanzado a la piscina también:
[[SPOILER]URL=http://imageshack.us/photo/my-images/850/throttlingno8.png/]
Sinceramente, creo que vale la pena. No son solo los 1.202 Mhz que se pone sin tocar nada más que el límite del consumo, en mi caso he probado con 115%, y perfecto a la primera. Es que además, puedes poner un perfil más adecuado al ventilador, y la temperatura se ha quedado en 74º durante el beenchmark. Eso sí, esa bios te sitúa el boost en 1.202 Mhz de forma automática, si te toca una que no llega, tienes que poner el offset en negativo, -10, -20, o lo que te haga falta para que sea estable. Pero como sube el voltaje a 1.20, los 1.202 Mhz los alcanza con facilidad, más fresca, y sin Throttling. Y mi duda, que había leído que en algunos casos no se bajaba el voltaje en idle, pues a mi me ha funcionado sin problemas, se baja el voltaje a los 0.862 en reposo.Mañana pasaré sesión de Crysis 3 para estar más tranquilo, y probaré a ver a cuanto me llega esta Titan :mad:
Por cierto, el proceso de flashear la bios, extremadamente sencillo, no lo había hecho nunca con una gráfica, pero no puede ser más fácil. Aquí es donde mejor lo explican:
Saludos
P.D. Teeth, si no lo ves claro, no lo hagas, la verdad es que da un "yuyu" hacer eso a una tarjeta de este calibre que no ves …...... pero que sería de esta vida sin la emoción del riesgoPerdona por no contestarte antes Pepillo, de dia el trabajo, por la tarde noche la familia, y de noche el equipo esta semana se me ha pasado volada, ni me he enterado…..
No puede uno andar por un foro del otro lado del mundo, lo reconocies en el primer post........xD.
Efectivamente estuve dandole vueltas y el pasarlas por agua y tener las tres "inamovibles" me animo a hacerlo. Y como comentas, yo tambien creo que vale la pena y mucho, y ya no solo apra benchear, aunque sea a modo casero como lo hago yo. Para jugar es donde realmente ganaremos rendimiento sin apretarlas apenas, ademas de poder midificarles el perfil de ventilador los que las llevais por aire.
Veo que has tardado poco en animarte tu tambien no........ ;).
Has confirmado eso del paso a 2D en escritorio?, yo intentaré tenerlo montado esta noche, pero me queda mucho trabajo por hacer, no sé si me dará tiempo.
Que Bios metiste al final?, yo metí una que era 121nv150, y ademas ni comprobé a que frecuencias me trabajan sin OC.
Un Saludo…
Bien, es correcto. Si te fijas en las gráficas, el GPU clock ha sufrido algún pequeño pico, el consumo ya está al límite y no se puede hacer nada más sin quitar esa limitación de la bios. Yo no soy ningún "overclocker" serio. ELP3 o Jotele, por ejemplo, saben mucho más que yo de estos temas.
No te comas más la cabeza y ponte a jugar, que te va ha dar algo ;D
Saludos
Mas quisiera saber yo la mitad que el amigo ELP3, lo que pasa es que me gusta sacarle todo el rendimiento posible hasta al último centimo que me gasto en hard, si está ahí porque no utilizarlo…....... ;).
Bueno y un bencheo y verte en el Hall of Fame, de vez en cuando tambien agrada.........xD.
Un Saludo...
Al final esta mañana he pillado un par de vuelos y a media mañana en casita, comida y montaje de RL.
Pepillo las mías si que estan frescas, esta imagen es después de 6 unigine seguidos.
Temperaturas en idle: entre 20 y 21º C.
De serie ( son SC no las normales)entre 30 y 31ºC y de ahi no pasan.
Los voltjes me bajaban a 1,13V, ahora se quedan en 1,16V ( todo de estricta serie) lo cual me imagino que podrán subir más sin tocar BIOS. Ahora me toca recoger todo que tengo encima de la mesa, si lugo puedo quizas las pruebe a subir como hice el domino pasado sin tocar el volataje aver si han ganado, aunque supongo que si:!
Vaya temperaturas majo, impresionantes, que bloques metiste al final los EK?, como tienes el circuito??
Yo al final compré los Koolance, son los que mas me llamaron la atención, y al comentar eso de los condensadores al aire de los XXL, no me lo pensé dos veces. Te leí eso de los R22, estos los traían al aire, aunque llevan su hueco en el bloque. Así que después de dos horas de darle vueltas a la tarjeta desnuda, probando combinaciones, para ver como podía ponerle pad´s, encontré la combinación perfecta, los dejo disipados y el resto de componentes no se alteran.
Aún las tengo encima de la mesa, espero poder terminarlas esta noche aunque no sé si me dará tiempo…
Por cierto y aprovecho para preguntarte tu opinión sobre esta fuente:
EVGA SuperNOVA NEX1500 Classified
Con las gráficas con un leve OC y el 3930 a 4,9, se iba el equipo a 1100W, así que como quiero estar tranquilo y la Enermax que tengo tiene ya 5 añitos, no me la quiero jugar. La he comprado. Me llega hoy, me ha encantado que traiga dos juegos de cables enfundados, y el sof de control de la psu, ademas es configurable; mas potencia, un solo rail, todo con switch.Vamos a mi me ha encantado. Pero tenía ganas de saber tu opinión, ya que una vez hablamos sobre la Enermax Platimax, que era mi elegida hasta que me enamoré de esta.
Gracias por anticipado,
Un Saludo…

Jotole, that PSU was tested and the 12V rail was not very stable, in fact, the control software it comes with is 100% lying, I mean it sticks it on but it looks great. I don't know if you know a brand called LEPA, it's an enemax but the ones I've tried are even more stable than the enermax. Although I only have SLI for now, I have 2 power supplies installed, one for the motherboard and cards of 1600W and another of 750W for RL, fans, SATA drives, etc. I've always liked to install independent power supplies, well not always, only since I started working on power supply systems in electronic and computer devices. It's not usually said but fans create a signal offset and an induction, which causes bad regulations of the PSUs, not always but sometimes. There are cards or systems in which, the fan may generate something that descotrole the power control system, and it's not just the fan's consumption, I imagine you've heard this but I won't say more than I shouldn't. In some cases it's proven that if you separate the power supply, as I just told you, you get much better stabilizations in the power systems, even in some cases you can lower the CPU Vcore and increase the FSB simply by separating the power supply of the fans and electromagnetic systems in general. call it motors. I forgot, Jotole if I have the EK CSQ (the ones with the circles that Eddy insisted on) and aesthetically, to my taste and with the transparent bridge they look very very good, I repeat to my taste, thanks Eddy. That is, parallel circuit. By the way here you can post without trolling, incredible -

Well I had no idea what could improve a team having two power supplies, for the moment I'll leave it in the pipeline, although it would enter 2 power supplies in the tower, I bought this one so as not to have to do it.
In the 4 way team I tried it and I didn't have good results, it gave me problems. Praimus, he has it like that too and it works well for him, with 2 power supplies, but I tell you that my experience was an odyssey. I mounted the Enermax of 1250W and a corsair of 750W, the enermax for gpus and the corsair for the rest, the team was very unstable. It was to remove the Corsair and all the problems were over.
I just received the power supply, the truth is that it is impressive. The power supply overflows quality in all parts, lacking to know what it carries "inside", there I get lost, that's why I ask for your opinion.
It was half necessity, half whim, the Enermax of 1250W, meets the team, but it will always be almost at 100%, the fan goes crazy with that load, normal, and I've already had it like that for a long season. So to avoid problems and since I'm building the pc from 0 again, I didn't want to complicate my life, and have to change the power supply soon. I will watch it closely, and if I see strange things, we will have to study other expectations…
This is the restructuring that the team is suffering, having started I have changed all the rl.... UltraMod
Many Thanks, with you one never stops learning…........... ;).
As soon as I have the team assembled I will pass with tests........
A Greeting..
P.D. Yes, I know LEPA, and it has very good references, but in the end you always end up with the one you least expect...........

Jotole is also true that after sending them to be tested and passing EU quality control, eVGA had to make some corrections to solve the problem, but of those reviewed I don't even know if they really exist or not, I can't tell you more.De anyway if you have a voltmeter measure what it really gives and what the software indicates at different loads and you will see the deviation if it exists as such.
The biggest problem with using 2 power supplies is to interconnect the power between them. If they are both identical there should be no problem since the system pulls from the power supply that has the least voltage drop to level both, but it is not always así.Es better to separate the power supplies, each one powering a part of components and the other another part, but BE CAREFUL that the components are not interconnected. For example, a PSU to power the connectors of the graphics (power circuit 8+6, 6+6, etc.) and another to power the control circuit (pci socket of the motherboard), since in Nvidia, at least, both power supplies are independientes.La motherboard does receive a signal from the power circuit but it is simply so that the motherboard knows if the graphics card is powered or not, it is a control signal not a utilization signal.
The issue is that there are motherboards that have a 4-pin molex connector to reinforce the 12V power supply of the graphics (in theory the socket) but that can be bridged with the power circuits of the connectors and this can cause problems. In the rampage IV that has this connector, for example, I asked Asus if it was interconnected with the power circuitry through the motherboard, but I didn't receive an answer. Then I asked in the ROG forum and neither, no one knows. My idea was to put 3 PSUs. One to power the connectors of the 4 graphics, when I have all of them. Another for the motherboard and CPU and another for the rest of the components of the computer.
It is very dangerous to use 2 PSUs and have each one power a part of the hardware and that it is interconnected through the placa.Si one PSU doesn't work for whatever reason, all the power supply of that part of the hardware will go through the circuitry of the motherboard and you know what would happen, right? Electronic roast and extinguisher at hand. And that cannot be avoided even with a well-designed motherboard. To prevent this from happening, 2 solutions:
1º. Totally independent power supplies with independent circuits (never any problems)
2º Interconnect all the power supplies of the 2 sources (total parallel circuit) you could end up having some problems if one power supply is different from the other, I don't mean in wattage but in differential response time between one and the other.
In power supplies and by logic and common sense there is a rule and it is that it is better to have 2 power supplies working at 75% than one at 100%, not only for risk of breakage but for quality of power supply -
Jotele, the bios I put in was taken from here:
http://www.evga.com/forums/tm.aspx?m=1891166
it's the BIOS1, from "Naemon", which unlocks the power limit up to 150%, the fan up to 100%, and sets the Boost to 1.202 Mhz, and yes, at rest or low load, it lowers the voltages without problems. I love it, I've had several sessions of Crysis 3 and the core doesn't move from 1.202 Mhz with the memos at 6.302 Mhz, stable and without problems. I've passed the whole battery of tests, Unigine, 3dMark, 2011, Vantage, etc. pulverizing all my previous records, and with the right fan profile, at lower temperatures. It's an amazing card, I overdid the bios. And with RL, it must be for launching rockets, who knows where you can get to, look at what the ones from Majo do without touching anything.
Majo, impressive temperatures. Ta lowers the consumption a lot and you can raise them a lot without touching anything else, congratulations. Very interesting about the power supplies, I've been using a Corsair HX1000 for a few years now, which are actually two power supplies in one box, and I'm very happy with it (of course the maximum has been an SLI of GTX580, for tris or those things, I wouldn't reach it anymore).

The cooler that comes standard is very nice and whatever you want but not very effective, as soon as you lower the temperatures it's amazing how much they perform. Today I am seeing and looking for many results, which I had never done with my other graphics, in fact it's the first time I've touched graphics, that is only to test, that they are already standard again and I am realizing that mine really work well. When the different brands release these graphics with custom coolers people are going to be amazed. I am the least qualified to talk about price but in my opinion if they cost what they cost it's because they are worth it and the moment they improve via drivers what can I say. There are many comments that if they are based on the gtx680 and these already have mature drivers, but they really look little like them, especially in power management and there is a lot to be done there. That said I am afraid of electromigration in these gpus if people go too far with the voltage. As eVGA selected some of the gpus for their hydrocooler they are going to be great, that is if they are also priced well.
In the end you come to the conclusion that almost without doing Mod-BIOS simply by improving cooling, the performance improves a lot.
From what I have commented with a coworker teeth has not had much luck with his, although they should have been worse, but if I could cool them more I think they would perform a lot more seeing what happens with mine.
Pepillo the ones I posted here today are different from the one I posted the first day, these according to my partner and what I saw yesterday, are better, things as they are -
I don't have RL, nor an i7 3960X, nor SLI, nor any of that, but I still "wax it" when I'm bored, and I've tried to keep pushing it a bit:
1.228 Mhz, it still doesn't protest and is scaling results. Majo, you're right, the Titan is a great card, what does it matter to me to "soak it"? But I'm not going to do it, this is just to bench a little, as it is I think it's a beast for playing anything.

Hello again everyone.
As you know, I have personal issues that, for the moment, make it impossible for me to have time for anything else. But since I try to read you daily, I got bitten by the mod bios bug, and I wanted to know how right I was when I thought that Nvidia capped TITAN with certain intentions and from what I see, I wasn't far off.
I always thought that with a proper OC, these TITANs would easily reach the level of a stock GTX 690, and from what I see, I wasn't too far off...
With just 1.21V fixed, that's for sure, this card is an endless BEAST... without RLs, without stories, with its maravislloso heatsink and only with the bios that keeps the clocks fixed, and especially that 1.21V... you see, just 1.21V that lets it feed those theoretical 300W that the power target can give without restrictions with those 8+6PIN, it's capable of benching at almost 1270MHZ and getting some numbers that a stock GTX 690 would want if it could.
If it does this with just 1.21V maintained... imagine what could be done with the craziness that AMD allows, or rather, allowed, of more than 1.35V... although it's clear that each brand works differently. But anyway, I'm sure that with just 1.25V, the good units would stand at 1300MHZ with stock cooling.
This card is undoubtedly a world apart from everything else, light years ahead of the ones that exist in monogpu, and with the performance of a dual but without its problems.. as I say, impressive. Almost 6000 GPU score points in Xtreme... 65-70% more than a 680 or 7970 oced at the same frequency... almost nothing...
Greetings to all...

Hello again. Thanks Majo for looking at this for me. I'm still in doubt about what to do and, with the luck I have, I might get another one that's even worse... Yesterday I did various tests. As I have a nagging doubt about how this card works, I ran OCCT in version 3.1, the best tool I've had for testing graphics overclocks. It's curious that, at shader complexity 0, the card runs at 837 mhz. The minimum of how Nvidia marks it. I can raise it to 920 without artifacts appearing. This translates to about 1045-1058 stable. Not to mention the throttling that appears as soon as it exceeds the limit. I would like, if any of you are kind enough, especially to you Majo, since you have the SCs, to see if, by passing the stock OCCT the card (not SLI) goes down to 876 and to what voltage (since the SCs have their minimum at 876). I get 1150, or so I think, with throttling, of course, by raising the voltage to the max. Of course it oscillates between 1150 and 1163, but, as soon as the consumption goes up, it goes down to 1150 and 1.18 or 1137-1110.. ELP3, on which card did you test the bios change?, of the four you have, and, the laziest one to what do you have it working?. I'm sorry you have family problems. I hope they get resolved. Greetings to all. -

Greetings to all...
You've already been tempted by the Titan, it was clear that they were intentionally capped, besides that they didn't allow custom models, but those frequencies in such a large chip with so many transistors prove that the node is capable of high frequencies, when they said they would come to 875mhz I already imagined that they could easily bench at more than 1200mhz.
A GK104 could perhaps stretch a bit more in frequency as it's a much smaller chip, but the 28nm seems to allow 1200 MHz, then it will depend on the voltage and power supply of the card, the cooling or how good it comes out, but I believed a while ago that 1200 wouldn't be difficult in those Titans.
Even that they would gain more since they have better performance per clock, they are more powerful cards and every MHz should be noticed more than in a 680.

With just 1.21V fixed, that is, this card is an endless BEAST... without RLs, without stories, with its maravilloso cooler and only with the bios that keeps the clocks fixed, and especially that 1.21V... you see, just 1.21V that lets it feed those theoretical 300W without restrictions with those 8+6PINs, it's capable of benching at almost 1270MHZ and getting some numbers that if a stock GTX 690 wanted.
If it does this with just 1.21V maintained... imagine what could be done with the craziness that AMD allows, more than 1.35V... although it's clear that each brand works differently. But anyway, I'm sure that with just 1.25V, the good units would stand at 1300MHZ with stock cooling.
This card is undoubtedly a world apart from everything else, light years ahead of the ones that exist in monogpu, and with the performance of a dual but without its problems.. as I say, impressive. Almost 6000 GPU score points in Xtreme... 65-70% more than a 680 or 7970 overclocked at the same frequency... not bad...
Sorry to read about the problems. Whatever it is, I wish you luck and that they get resolved.
What do you mean by 1.21 maintained? To me, at least in idle, if it goes down the voltage.
Another question that comes up when I see your screenshots. When I flashed the bios, the core went to 1.202 Mhz without raising the offset at all. But if I put the precision to boot with the system, when I restart I have the 1.006 Mhz again, I had to create a profile with 200 offset. It's not really a problem, in fact, I prefer it this way, the only thing is that you have to be careful because as soon as you get distracted you put the +200 over the 1.202, and at 1.400 peta, of course.
With the modified bios, the potential of the card is unleashed, all of us who have tested it agree. It's the first time I see with a new card, that so many people modify the bios, and it's that what you gain, is a lot.

Jotole también es cierto que después de mandarlas a testear y pasar controles de calidad EU,eVGA debió hacer alguna corrección para solucionar el tema , pero de esas revisadas ni sé si realmente existen o no, no te puedo decir más.De todas maneras si tienes un voltímetro mide lo que realmente dá y lo que marca el software a diferentes cargas y verás la desviación si existe como tal.
El mayor problema de usar 2 fuentes es interconectar la alimentación entre ambas.En caso de ser las 2 idénticas no debe haber problema ya que el sistema tira de la fuente que menos caída de tensión tiene para nivelar ambas, pero no siempre es así.Es mejor independizar las alimentaciones, cada una que alimente una parte de componentes y la otra otra parte, pero OJO que no esten intercomunicados lo componentes.Por ejemplo, una PSU para alimentar los conectores de las gráficas ( circuito de potencia 8+6, 6+6, etc.) y otra para alimentar el circuito de control ( socket pci de la placa), ya que en Nvidia , por lo menos, ambas alimentaciones son independientes.La placa si que recibe una señal del circuito de potencia pero simplemente es para que la placa sepa si la grafica esta alimentada o no, es de control no de utilización esa señal.
El tema está que hay placas que llevan un conector molex de 4 vias para reforzar la alimentación 12V. de las gráficas ( en teoría el socket) pero que sin embargo pueden llegar a estar puenteados con los circuitos de alimentación de los conectores y esto puede ocasionar problemas.En la rampage IV que lleva este conector, por ejemplo, yo pregunté a Asus si estaba interconectado con la circuitería de fuerza a través de la motherboard, pero no recibí respuesta.Luego pregunté en el foro ROG y tampoco, nadie lo sabe. Mi idea era poner 3 PSU. Una para alimentar los conectores de las 4 gráficas, cuando tenga todas.Otra para placa y CPU y otra para resto de componentes del equipo.
Es muy peligroso usar 2 psu y que cada una alimente una parte de hardware y que éste este intercomunicado a traves de la placa.Si una PSU no funciona por lo que sea, toda la corriente de aliemntación de esa parte del hardware pasará a traves de la circuitería de la placa y ya sabes que pasaria, no? Asado de electrónica y extintor a mano.Y eso por muy buen diseño que tenga la placa no se puede evitar.Para que esto no ocurra, 2 soluciones:
1º.Alimentaciones independientes de circuitos independientes totalmente ( nunca ningún problema)
2º Interconectar todas las alimentaciones de las 2 fuentes ( circuito en paralelo total) pudieras llegar a tener algún problema si una fuente es diferente a la otra, no me refiero en watage sino en tiempo de respuesta diferencial entre una y otra.
En alimentaciones y por lógica y sentido común hay una regla y es que es mejor que trabajen 2 fuentes al 75% que no una al 100%, no solamente por riesgo de rotura sino por calidad de aliementaciónMe interesa bastante ese tema, y teniendo ya 3 fuentes de calidad como tengo, en cuanto tenga el equipo ok, puedo mirar eso de la alimentación. A ver como conectarlas. Yo utilicé un cable de esos de 2 hembras para unirlas las 2, no sé si será adecuado, o te refieres a que encienda por separado.

Jotele, la bios que puse la saqué de aquí:
http://www.evga.com/forums/tm.aspx?m=1891166
es la BIOS1, de "Naemon", que desbloquea el límite del power hasta 150%, el ventilador hasta el 100%, y pone el Boost en 1.202 Mhz, y sí, en reposo o poca carga, baja los voltajes sin problemas. Me encanta, llevo varias sesiones de Crysis 3 y el core no se mueve de los 1.202 Mhz con las memos a 6.302 Mhz, estable y sin problemas. He pasado toda la batería de tests, Unigine, 3dMark, 2011, Vantage, etc. pulverizando todos mis anteriores registros, y con el perfil del ventilador adecuado, a menos temperaturas. Es una pasada de tarjeta, la bios la capaba demasiado. Y con RL, ya tiene que ser para echar cohetes, a saber donde llegas, mira lo que hacen las de Majo sin tocar nada.
Majo, impresionantes temperaturas. Ta baja mucho el consumo y puedes subirlas un montón sin tocar nada más, enhorabuena. Muy interesante lo de las fuentes, yo hace ya unos años que uso una Corsair HX1000, que en realidad son dos fuentes en una sola caja, y muy contento con ella (claro que lo máximo ha sido un SLI de GTX580, para tris o esas cosas, ya no llegaría).
Saludos
La mia es parecida, son todas mas o menos iguales, aumentando un voco el limite de poder.
Anoche al final hubo problemas tecnicos, un par de fugas….........xD. Así que no me dio tiempo a terminar el equipo. Ahora mismo lo tengo montado con el circuito de gpu´s lleno. Madre mia como mueven liquido 2 bombas, creo que nunca he tenido tanas ganas de terminar un equipo....
A ver si esta tarde cuando llegue a casa puedo escaparme un par de horas que es lo que me falta para terminarlo.....
Un Saludo..
Hola de nuevo a todos.
Como bien sabeis,tengo problemas personales que de momento,me hacen imposible tener tiempo para otra cosa.Pero como os intento leer a diario,me picó el gusanillo de las bios mod,y quería saber hasta que punto estaba en lo cierto cuando pensaba que Nvidia capó a TITAN con ciertas intenciones y por lo que veo,no andaba mal encaminado.
Siempre pensé,que con un OC en condiciones,estas TITAN se pondrían sin problemas a la altura de una GTX 690 de stock,y por lo veo,no me equivoqué mucho…
Con tan solo 1,21V fijos,eso si,esta gráfica es una BESTIA infinita...sin RLs,sin historias,con su disipador maravislloso y solo con la bios que mantiene fija los cloks,y sobre todo ese 1,21V...ya veis,tan solo 1,21V que le dejen alimentar a esos 300W teóricos que puede dar el power target sin restricciones con esos 8+6PIN,me es capaz de benchear casi a 1270MHZ y obtener unas cifras que para si quisiera una GTX 690 de stock.
Si esto lo hace con tan solo 1,21V mantenidos…imiginaos lo que se podría hacer con las burradas que permite,o mejor dicho,permitía AMD de mas de 1,35V...aunque esta claro que cada marca trabaja de manera diferente.Pero vamos,que estoy seguro que con tan solo 1,25V,las buenas unidades se plantarian en 1300MHZ con disipación de stock.
Esta gráfica indudablemente es un mundo y aparte con todo lo demás,a años luz de las existentes en monogpu,y con el rendimiento de un dual pero sin los problemas de ella..como digo,impresionante.Casi 6000 puntos de GPU score en Xtreme...un 65- 70% mas que que un 680 o 7970 oceadas a misma frecuencia...casi nada..
Un saludo a todos..
Jejejeee, otro que no ha resistido la tentación eh. ;). La verdad es que es una gozada ver las tarjetas trabajar así. En OCN, hay algún animalito que ha editado sus propias bios y les ha metido 1,35 y las pone a 1400. A ver quien es el primero de aqui que las prueba…............ xD. Y de paso se queda con un pisapapeles monisimo de aluminio...............xD.
Me alegro mucho de leerte, aunque sea fugazmente.
Un Abrazo y mucho animo ELP3….
