The GPU died today
-
Hey everyone . Today i changed my thermal paste on my 780 from EVGA. And i then noticed this weird discoloration. I tried wiping it off multiple times with alcohol, but it's not coming off, it clearly is a discoloration on the die. The GPU works fine though. Also, the "GK110-300-A1" text is almost gone. Any ideas ? Is it normal or will my GPU fail soon ? Have a nice day, thanks.

For the moment no issues whatsoever, i even came back to my old psu as it was more silent and i still can reach 106% TDP
-
Okay, problem fixed (for the moment). I checked the PCB of the GPU, and it turned out that the black metal plate was hella bent, so it was bending the PCB too. I then disassembled a 40th time the GPU and bent it a bit in the other side and i screwed it back to the PCB. Now when starting a stress test i directly get to 1124mhz and 95% TDP, like before, and it increases until it reaches 100% Power. The plate i am talking about is linked below. Ill tell you in some days if the problem comes back or if it finally over.

I got a soldering iron but i will lmore screw the GPU that it is already because it basicly sucks haha
-
They look very good. The solder joints are clear/shiny. I don't think the issue is related to the plug itself but more with the little chips on the power delivery part of the PCB. Bending a bit the GPU puts the good power delivery. I don't think i can fix it any more, because i cleaned it the most i could honestly.

Good news ! Kinda. I found that playing with the PCIE power plugs of the gpu or pressing near them while it's working changes the Power Limit (makes it go up to 100%). I then disassembled the card and cleaned the PCB around the power plugs and the plugs themselves. After rebooting: bingo ! 100% TDP and no stuttering anymore ! Only for a couple of minutes. See, it still got down to 85% Power, and playing with the GPU did the same behavior as before cleaning. I am now sure that the issue is really hardware. Important to know: when GPU power is at 100%, the core tention is at 1.150mv instead of 1.075. The core is just not powered enough to get full power, and it created stuttering and power issues. I will just get a new GPU i think.

With the fan at the lowest speeds, it behaves the same way. Its like a fast freeze every around 10 seconds, espetially when the power drops (i see it with HWMonitor)
-
Yeah i heard that furmark is not great for GPUs. And yes, all pads were there. Yeah it is the SC Acx version. When it does run at 100%, the fan spins faster because it heats more (it doesn't overheat). Also, manually increasing fan speed drops the Power even more sometimes and drop clocks too. Manually underpowering the GPU with AfterBurner makes the stutters disappear now.

I didnt express myself right too haha, when i said clean, i checked the thermal pads too, and everything was fine. Weirdly, inductors were covered with a gross "grease" when cleaning it. I removed it with alcohol and the GPU came back to 100%TDP for around 10 minutes, then got the issue again. I have a picture, ill link it The Furmak test is righ after booting the pc, and the inductors pic is before cleaning.

As i said in the 1st post, it makes most of 3d programs get big stuttering. And i OFC cleaned like shit the PCB. GPUz doesnt show any error. The clock is at 1058mhz. It is still higher than the clock the SC variant should have, but since the power is not used at its full potential, its useless to have a clock that "high" if the GPU doesn't power enough to maintain good performance. I remember like a year ago, GPU Power was at 100% smooth and clocks were stable.
-
As soon as the GPU gets stressed, the problem appears. It's like it forgot that he could go higher, so yeah it is in every GPU related things. I cleaned the GPU miltiple times with 90° alcohol, and I ofc checked the PCIE power pins of both of my PSUs and on the GPU. They are all clean. Also, i checked if the PCIE power plugs were plugged right and they are. Everything in/on the GPU looks perfect condition wise, even dust is pretty rare. Inductors look fine too.
-
That is a problem i got around 5 months ago, it was rare, but now it is always present. So no it never always done that

Hello everyone. This is my first post on this forum, because i am sure the LTT community will find an answer for me, and because I never found any answer anywhere else. My GPU is an EVGA GTX 780 SuperClocked. The issue is that it never goes to 100% Power consumption/TDP. This makes the frequency lower and creates awful stuttering. - In Nvidia Control Panel, i am in "Maximum Performance" mode. - In Afterburner, putting 106% Power Limit doesn't change anything, I keep being around 80/90% TDP max. - Underpowering the GPU works. - I reinstalled multiple times the Nvidia drivers, with different versions, and same behavior. - I stress test my GPU with either FurMark or Heaven Benchmark (both with the same behavior). - I have a 700W brand new PSU (2 weeks old), and with my old one i had the same behavior. - The GPU has the same issues on another PC. - Changing the core voltage doesn't change the voltage too (stays at around 1075mv). - I am on the latset VBIOS provided by EVGA for this GPU. - My GPU never goes higher than 74°C. My i7 2600 cannot be the culprit, even if it doesn't support PCIE 3.0 (another rig with PCIE 3.0 got the same behavior again). I search a fix for this issue for weeks, but i never found any. I hope you guys will help me to find what's wrong. Have a nice day everyone ?.
