Stuck with OC to Q6600 B3

[keop]

Hello,

After following the forum for a while, I've decided to make my debut to comment on a topic, to see if the overclocking masters can shed some light on it.

The thing is that my PC is quite old, I've been making small upgrades to it, but the base (micro, ram, etc.) is starting to feel very weak for certain games. The PC's specifications are as follows:
Motherboard: Gigabyte GA-965P-DS3 Rev. 2.0 with P965 chipset
CPU: Intel Core 2 Quad Q6600 rev. B3
Memory: 4xKingston 1GB 667 CL5 (KVR667D2N5/1G)
Graphics: AMD HD 6870
Disk: SSD Vortex 3 120GB

Well, I've followed the tutorials and posts I've found on this and other forums, basically I have installed Orthos, CPUID, and Coretemp to check the system's stability after overclocking. And what I do is, in the BIOS, I gradually increase the bus speed from 266 (with x9) which is the original value, by 10 each time without touching the multiplier since my goal was to reach 3GHz (333x9).
The thing is that on the second attempt, that is, when I increased it by 20 (to 288) everything went wrong, specifically what happens is that the computer restarts and nothing is displayed on the screen, so I can't even reconfigure the BIOS because I can't see anything, so I assume there must be some kind of underlying problem that I'm not considering (I suppose it's too early to have to modify the voltages).
So, the only thing I can do is reset the CMOS using the motherboard's battery and start over, but I can't get past this point...

Could someone please help me out? I don't know if it's the RAM that's messing up the process or what, to be honest I'm a bit lost...

Thanks a lot in advance!

Have you read the Basic OverClock Guide - HardLimit?

Do you set the memory to 266 before you start touching the FSB?

Salu2! and Welcome to the forum :sisi:

Thanks for your reply!

Well, as I mentioned in the post, I have read the basic overclocking guide (and some other related posts), but it's clear that I didn't understand something well or I'm not doing it right...

I don't get what you mean about setting the memory to 266 before touching the FSB. Isn't what I increased from 266 to 286 precisely the FSB? The BIOS allows me to set a multiplier for the memory later, the minimum it allows me is x2, so I end up with 266x2=532MHz or 286x2=572MHz.

My idea was to reach 333 on the FSB, to have 3339=3000MHz on the processor and 3332=667MHz on the memory (which is the speed marked by the manufacturer).

What am I doing wrong?

Thanks!

Try reading the first sections of the Guide more carefully, or try directly to set the memory @266 and increase the FSB a bit, so you can see what happens :facepalm:

If you are not willing to spend many hours doing tests, then OverClocking is not for you :nono:

Salu2!

Of course I am willing to spend hours on overclocking, that's why I am here. I have spent many hours up to this point and I am stuck, and since I am new to this I am trying to ask for some help to see if someone is able to guide me a little more, I don't know why you assume that I don't want to spend hours or that I haven't read the guide. I suppose I am saying something silly for you to think this, sorry if that's the case, I am trying to learn and any advice will be welcome.

In my BIOS to change the values is this screen:

In the memory it admits these values for the multiplier:

If I change the "System Memory Multiplier (SPD)" to Manual, I can choose a value between 2 and 4 that, when multiplied by the "CPU Host Frequenzy (MHz)" (let's say the FSB), gives me the total speed that the RAM will have. That is, if I have the FSB at 266 (as it comes by default), with a multiplier of 2.5 I would have a speed of 667MHz (as it comes by default).
And what I wanted to achieve is to have an FSB at 333 with a multiplier of 2 so that it would catch the 667MHz of the RAM and the 3GHz of the processor (333*9).

This is what I have been trying to say since the first post, but it is obvious that I must be missing something due to your comments, can I know what?

Thanks!

That motherboard, if you don't do a mod against vdroop, you won't be able to overclock it much with that processor, I don't think it's because of the memory, it's because that motherboard has a brutal vdroop and more so with 4-core processors.

I had a rev 3 and with quad it was very difficult to get a decent OC, because it asked for a lot of voltage.

As the first thing is to find the limit of the processor, and its multiplier can not be increased, we have to play with the FSB, so we must make sure that we are not limited by another side, which means that we must relax the memory configuration, to do the tests (in your case, put the multiplier to 2.0).

We deactivate all the power saving systems of the processor, and the SpeedStep and similar, so that there are no more changes than the ones established by us, and you start to try to increase the FSB little by little.

If you can not start, you can try to increase the Vcore a little, or put the timings of the memories in manual (at least the first 4 values), in case it is setting too aggressive values and can not start.

Salu2!

Wow, true, there is a 0.5V variation between what I configure in the BIOS and what CPUZ shows me.. wow. If I see that I can't get there, I'll do the pencil mod. Thank you very much!

And well, it seems that I'm already making progress because I've managed to put it at 3GHz (333*9) with the FSB at 333 and the x2 in the RAM. In the end it had absolutely nothing to do with the memory and the configuration I had initially posted was correct (the first comments from Fassou confused me a bit), what was happening is that I needed to put extra voltage not to the CPU but to the chipset (I achieved this by trying all the combinations, which are not few..), which in my motherboard appears as G(MCH).

Now I have it with +0.1V on the chipset and 1.285 on the CPU (a little bit below my VID), it seems stable after running Orthos for 1 hour, and the maximum temperature I get is a peak of 68º with the CPUs at full. How do you see it? Is it a good temperature?

By the way, I also tried the Intel Burn Test to check stability but it gives me a blue screen with the default configuration, I don't know if I still have something wrong or if I need to configure the program or something.. I did a full MemTest and everything worked perfectly.

[Fassou]

If the IntelBurnTest fails, you have something that creates instability.

If it is with the default configuration, in addition to setting the decimal reinforcement voltages, check the memory settings, especially the T Command Rate.

@keop:

Pufff, cierto, hay una variación de 0,5V entre lo que configuro en la BIOS y lo que me marca el CPUZ.. vaya tela. Si me veo que no llego, haré el mod del lápiz. Muchas gracias!

Y bueno, parece que ya voy avanzando porque he conseguido ponerlo a 3GHz (333*9) con el FSB a 333 y el x2 en la RAM. Al final no tenía absolutamente nada que ver con la memoria y la configuración que había posteado inicialmente era la correcta (me despistaron un poco los primeros comentarios Fassou), lo que pasaba es que necesitaba meterle voltaje extra ya no a la CPU sino al chipset (esto lo he conseguido probando todas las combinaciones, que no son pocas..), que en mi placa aparece como G(MCH).

Ahora lo tengo con +0,1V en el chipset y 1,285 en la CPU (un pelín por debajo de mi VID), parece estable pasándole el Orthos durante 1 hora, y la temperatura máxima que me pilla es de un pico de 68º con las CPUs a full. ¿Cómo lo véis? ¿Es una buena termperatura?

Por cierto, también he probado el Intel Burn Test para comprobar la estabilidad pero este me saca pantalla azul con la configuración por defecto, no se si tengo aun algo mal o es que hay que configurar el programa o algo.. he hecho un MemTest completo y ha funcionado todo perfecto.

Dale al MCH algo de voltaje,por lo menos +1 o +2,tendras que meter voltaje a la memoria y 333x9 quiza no tenga demasiado vdroop,yo recuerdo que en esa placa necesitaba el mismo voltaje para subir a 3400 mhz un Q6600 G0 que en una P5K premiun para hacer 3900mhz,tenia demasiado Vdroop y tenia que compensar demasiado subiendo el vcore,ademas que era hasta dificil mantener estables los 3400,aunque en la P5K tampoco es que fueran estables los 3900,pero si valian para pasar benchmark y parecia algo mas estable.

Why is it necessary to put more voltage into the memory? The memory tests work apparently well for me, I did a complete one with the mem test (I left it on all night) and it marked everything as OK.

I will try to put something more into the chipset, although the Intel Burn Test does not pass me, I have tried to be playing for about 2 hours with the CPUs giving it everything and it seems stable, that is, they get to about 63-64 ° C of maximum temperature each CPU. With the orthos after an hour of stress test it gets to almost 70 ° C.. Is it a good temperature or is there a risk of burning the CPU?

Greetings.

With that CPU it is normal to get hot, the B3s were very hot, the G0s were already less and could go up better, putting voltage to the memories if you have them for example at 800 and 4-4-4, if you have 1.1 and fsb at 333 besides you didn't put a manual latency whether it's 4-4-4 the easiest is that it doesn't need voltage, now if you put 400x9 the memory always goes to double the fsb and it is usually necessary to give a little more voltage, your memory should say what voltage and latency it needs besides what frequency, although it can be put to less or maybe to more if it comes out good.
