freeagent, This is some kind of old PSU with 500W. I bought it just for testing. But I'm 100% sure that it is not a PSU issue. I have tested few weeks ago RTX 3070 on the same setup and everything worked just fine.

Hello everyone, Looking for a help with GTX 1070 repair. Card works just fine until it gets some load (for example benchmark). I've tried to check voltage when card crashes. Is seems that there is a problem with Vcore, because after crash Vcore, PEX and Vmem goes to 0. Card has uP9511...

Hello delshay, I'm very thankful for your test. However I do not have ESR Meter also. And it is even more expensive than Voltage injector. Also I have tried to freeze chips and check which heats fastest, however still nothing. All of them looks the same. Bottom of card also. So I think I'm...

Hello delshay, I agree with you, ESR can really help to find circuit on phases. However this is a different situation, where I know that short circuit is on RAMs/GPU side, no on one of two phases MOSFETs of Vmem. I have removed inductors and short circuit was on chips side. ESR will not help me...

Thank you all for your feedbacks. The problem is that I was injecting voltage with laboratory power supply, which max current output is 5A. I do not have any power supply which could generate 1V with higher current. I have tried to check voltage drop, everywhere dead short. I will think about...

Hello DeathtoGnomes, So you mean, that without removing each and single chip, it is impossible to indicate where short comes from?

Hello P4-630, I would agree, but it is very strange that I do not find any heating spot anywhere..

Hello everyone, So I have this Gigabyte GTX 1080 TI Gaming 11GB. It has short circuit on Vmem. I have removed both inductors and it seems that short circuit comes from GPU, RAM chips side. I have tried to inject 1V with 5A. I have checked through thermal camera, nothing heats up, no caps, no...

I agree with you. But electronics is also as a hobby to me, so I like to try fixing it. If you know where it is possible to buy GPU, can you share? Or is it confidential?

Hello eidairaman1, Thank you for your response. I also thought about IMC, well which is basically the GPU. So yeah, I think the only option left is to try to heat GPU, if it will not help, new GPU required, not sure if it is possible to get it anywhere.

pavle, Yes, I would never put it in the oven. Hot air station with flux is the only way. But this is the last option, currently I'm looking for what I could test more.

rafik2019, Yeah I know about that stuff. This is the last optiom to go for hot air heating GPU with some flux, to clean oxides and to see if this helps. Bomby569, I do not think that it is releated to VRAM. I had GTX1070, where two of the VRAM Vref voltage were zero. However it did not spin...

Hello rafik2019, I always keep in mind that GPU may be dead, however I do not know how to prove it. If the GPU would be dead, I believe I should see some unusual measurements on PCIe pins. If the GPU is dead, so the card goes to trash bin. Other option that some BGA ball may be broken. Which...

Hello pavle, Thank you for your reply. As far as I know heating means that voltage is preset which is of course a good sign. However I do not know how hot it is normal for GPU to get in such scenario. I have seen some graphs of PCIe interface on the internet, where it shows that power...

Hello everyone! I'm looking for support on how to fix Gainward RTX 2080 Super Phantom GHL. These are the symptoms: 1. Fans spins at 100%. 2. Black screen. Even screen monitor does not detect anything connected to it. 3. I get five beeps from a buzzer. 4. Windows shows Error 43; 5. nVflash...
