Asus Strix GTX 970 OC bricked

[predyy]

Hi there!

Last week I have been playing around with my video card on the overclocking topic using MSI Afterburner. I have reached a (seemingly) stable state, that also involved voltage change. Haven't used it for a couple of days, then when I turned it on, it started to lose it - the image started blinking, blacking in and out, then after a few reboots stopped working.

After spending 6-7 hours browsing forums for solutions, I've tried to unbrick it with the following methods:
- placing it in another PCI-E slot;
- trying it out on another mobo;
- flashing it using nvflash in DOS mode - got a "No adapters found" error message and two beeps;
- 1-8 pin method, which I don't know if I did it on the correct chip - got the same message.

Unfortunately neither of these worked out. My only hope is in the 1-8 method, and that I've tried it on a chip, that has nothing to do with the BIOS (I've also read about the oven method, but since I don't have a spare oven, won't try it out). Demounted the cooler and the backplate, could't find a chip that has 8 pins and could have anything to do with my case.

Can anyone guide me towards the right direction/tell me if it's a lost case or not?

Did you try it on another PC ?

that also involved voltage change.

What sort of voltage ? And how did you changed the voltage ?

Yes

I maxed out the core voltage in MSI Afterburner. After seeing that it behaves strangely (blackouts), i turned the OC profile off. It may have been too late, I'm not sure.

Take pictures of all white stickers on the card, get a picture of the ram chips on the card too, post them all here.

It's very unlikely that the GPU core itself was damaged by the higher voltage however the VRMs might have went bust.

They were probably shoddy to begin with and the increased current that was going through them was the tipping point. Rare, but it happens.

But again I am just guessing.

Ok i found your bios chip

At this page you will find multiple bios for your specific card, look at ones that specify strix OC 1114/1753, they all support elpedia memory.

I was pretty sure that it had 2 years warranty. Now you saved me. Thank you!

Ok i found your bios chip

I have already found this list, but not the chip itself on the board.

Ok from the gpu die look up and right, there is a chip with a dimple on it, that is the bios eeprom. With my links in my signature you should be able to unbrick your gpu, i will also provide videos
