Hi,

I bought this Nvidia GTX 1080 - Zotac Extreme AMP! from eBay.

The seller says that you can use it without the drivers and i try to do it, but Windows always installs driver and the screen crashes.

I try a lot of things:

  • Install Last and Older version of Nvidia Drivers, always black screen and i can´t use the computer with the VGA. With the CPU integrate GPU i can still using it.
  • I reflash the BIOS with techpowerup one, without errors but still the same.
  • I use NVIDIA Mats to search for HW problems and nothing wrong here, pass all the test....
In GPU-Z it shows 0 MB of VRAM, and lost the Bandwitch and Bus Bits of the board.

Pics here:

Someone can help me?.

Thanks a lot.

(Im new here so if i do something wrong, tell me :)).

Welcome to the forums, newcomer!

If GPU-Z shows 0MB in video memory size, then the card's either gone kaput or the VBIOS went somewhere it shouldn't have. The last time the same issue happened to me, I had to RMA the card. If reflashing the VBIOS or reflowing the memory on the GPU doesn't help then the card's an expensive paper weight at this point.

Thanks for your reply.

I try to reflash de BIOS of the VGA using this guide:


and using this BIOS

https://www.techpowerup.com/vgabios/185008/zotac-gtx1080-8192-160616

And stills in 0 MB of VRAM and same problems of crashing.

I have some tools here and i can try to change components but i dont know what component can be the bad one, cause in MATS the GPU doesnt have errors, the voltages of the MOSFET/PCIe seems good, ....

Thanks a lot Lutfij.
