GTS250 in a water bath.

[Sylver]

Yes, it sounds completely like cracked silicon… This reminds me a lot of an Athlon XP that had the pads in bad condition, in the end the heatsink broke the corners of the silicon core and that little chip turned into a crack from tip to tip. End of its life.

If you are not planning to invest, look for a cheap second-hand graphics card, there are good options and even better than that GTS250.

Well, I've disassembled the heatsink and it seems to be perfect. I'll post a photo later so you can see it.
The solution was simple, Gigabyte GT630 with 2 gb ddr3 128bit. 62€.
This one in particular: GIGABYTE - VGA - GeForce 600 Series - Chipset GeForce GT 630 - GV-N630-2GI - Specifications
But I think what was happening is that from the first overheating, a solder joint weakened (it wouldn't make good contact), when the pressure increased it made contact and worked better, but in the end it ended up breaking.
When I'm in Seville I'll give it a little heat in the oven, to see how it goes.
Regards and thanks to everyone.
So that's it, I'll upload the photo of the core later.

By the way, the temperatures of the new one are nothing like the old one.
Idle –> 32ºC
Full Furmak --> 52ºC
The power consumption is also nothing like the old one, 150w from the GTS250 against 65W from the GT630.
I've continued playing Rage, which I had forgotten about on the beach PC, and as for gameplay, I haven't noticed any difference in performance.

well if that graphics card is going to the trash, let me know, I'm looking for things like that to keep myself entertained. I get very bored

[Chino]

@JuezDred:

bueno si esa grafica va para la basura, avisa, que ando buscando cosas asi para entretenerme. que me aburro mucho

Ok en cuanto llegue a sevilla la hornee y no rule si quieres te la mando.
Salu2.

[Chino]

I have to tell you that the guy at the store told me that if I didn't like that gt630 (it was the only one they had in stock) I could exchange it, and after trying it out a bit I decided to exchange it for an Asus HD6670, by putting in 6 € more.
Salu2.

[JuezDred]

it's not a bad choice, I use yours as my main card and an nvidia as a secondary one.

[Chino]

By the way, how do you see the gpu?

Thanks.

[Bm4n]

Do you have two resistors bridged?

[Sylver]

It seems it's just thermal paste. It doesn't look bad, it looks good at first sight.

[Chino]

I would say they are capacitors, but they are not bridged, it's the thermal paste, which is supposed to be non-conductive. At least that's what I think.
Anyway, I'll remove the paste to be sure.
As for the gpu, I was referring to the fact that I had been told that the image of the failure was normal when the silicon broke.
Apparently nothing is visible from the outside.
Regards.

The SMD whether it's a resistor or capacitor, it doesn't matter, the thermal paste is never 100% insulating and more so if it's metal-based; clean it well if you don't want problems. It also looks like a separation in the silicone that surrounds the core, right? And I didn't understand that about the silicon breaking, what do you mean, do you see the surface of the core broken or loose? Usually they used to break visibly, it's possible that some internal solder was already bad as you say.

[Chino]

It's the effect of the light, it came in from that side and was reflected giving that impression.
Regarding the broken silicon, I meant that the colleagues had said that the screen capture I had put up before with the artifacts could be a symptom of the core being broken due to the increased pressure from the heatsink springs.
"In my defense" I have to say that the washers are tenths of a millimeter and even when I pressed them with my fingers, they still gave way and sank more. So they didn't have to apply much pressure to bend those washers.
What I do notice is that the 4 corners of the core are scratched and there's nothing in the center, could that be a symptom of a bad fit between the core and the heatsink?
Salu2.

[Sylver]

It doesn't look broken, what we were talking about was something more striking, like silicon shavings scattered around and the corners "pierced".

I don't know about a bad fit, but what it is a symptom of is that the heatsink has moved quite a bit over the core, manually I suppose, since those scratches aren't made with the standard placement (or at least I'm not aware of it).

Regards

[Chino]

The truth is that it is not so scratched at least with the naked eye, what happens is that with the macro zoom and 18.8mpx you can see even the hairs like sticks.
I probably made a mistake when I said to remove it and I put it more than 10 times.
I will continue to investigate to see what it could be.
Tomorrow I will remove all traces of thermal paste and I will tell you.
Regards.

Es coña.

Yo el núcleo lo veo bien por fuera, pero esa rayas son de eso, o núcleo o memoria. Vete mirando una gráfica.

@Chino:

La verdad es que tan arañado no está al menos a simple vista, lo que ocurrees que con el zoom macro y 18.8mpx se ven Hasta las pelusillas como palos.
Probablemente me que de corto cuando dije que lo quite y puse más de 10 veces.
Seguiré investigando a ver que puede ser.
Mañana quitaré todo rastro de pasta térmica y ya os contare.
Saludos.

La parte del GPU está aparentemente bien, es normal que se raye un poco, pero está bien. Ahora que miro el resto de componentes abajo a la izquierda se ve como si faltaran un par de resistencias y un condensador de SMDs, el estaño se ve como arrancado, quizás se te hayan soltado.

Muchas gracias a todos por las respuestas.
He limpiado todo de silicona, la vuelto a aplicar y por arte de birli birloque vuelve a funcionar, pero se sigue calentando y funciona asi:

Esto me suena a no core roto sino a memoria jodida.
¿Que os parece a ustedes?
¿Puede averiguarse que chip de memoria es el que esta estropeado? En caso de que sea de memoria, claro esta.

Franziscaner tu core esta impoluto. El mio esta mas "currado"
Bm4n esos componentes ya me he dado cuenta pero nunca han estado ahi. Vamos, que no se han caido o han sido arrancados.

Memoria jodida o tema relacionado con la memoria (bus u otros, como controlador o interfaz de la pgu a memoria). No le des más vueltas, está muerta y no tiene solución.

A veces se sale de ésta con el truco del horno, que puede "rehacer" alguna conexión de la gpu o de los mismos chips de memoria que se haya roto con el uso (algo relativamente común en tarjetas RoHS, sobre todo de primera generación). Pero de todas formas, fuera de este truco extremo, yo la daría por muerta y no me rompería más la cabeza.

No es un problema de disipador colocado, eso SEGURO.

Me esta pidiendo a gritos un horneado.
En cuanto llegue a sevilla, aqui en la playa solo tengo microondas, le pegare un buen repaso.
Esperemos que reviva.

EDITO: He buscado un vecino en la urbanizacion que tuviese horno y me quisiese hacer el favor de hornear una grafica.He encontrado unos vecino muy amables y se han prestado al experimento.
CONCLUSION:
LA GRAFICA NO ARRANCA, jajajajajajajajaja
