Old ATI card doesn't work with any drivers

[psk94]

My main vid card died on me, trying to use an old pci-e ati 6870. Works 100% fine forever in 2 different PC's without any drivers installed, listed as a microsoft basic display adapter using low resolution, 1280x1024 max. As soon as I install any drivers of any version or from windows update, instant black screen forever no matter what after that. Same thing booting up Ubuntu, the low res loading logo screens work fine and then once a driver is loaded going to the desktop instantly gives a blue screen with vertical lines and stuck.

Checked gpu-z and lists the rops and tmus wrong for this model, and as a microsoft basic display adapter. Pretty sure it's a diamond ati 6870 though as it has 2x6 power connectors, wouldn't be higher model card than this, but thought it was lower... don't think any lower models have that power plug config though.

I'm considering flashing the bios, not sure what else to try at this point. Note it has a custom cooler installed from arctic accelero line, so different fan plugged into the gpu board than default... doubt that would make any difference. Any advice would be appreciated.

Edit: The gpu-z specs were a bit different before than pic using onboard gfx + 6870 running in background, rops/tmus were listed as 8/24, so guess that doesn't matter and gpu-z reading it wrong.

If the card is unstable when drivers are installed then it's defective. GPUz reading without installed drivers are almost always wrong, since the information is provided by the AMD/ATI drivers.

Dunno if I would use the word "unstable"...it instantly goes to black screen as official drivers load for it, but will work without artifacts or issues for an entire day using microsoft default driver with low resolution. It hasn't ever done anything random or artifacts, so it either can't handle the high resolution and defective or wrong/corrupted bios making it use the wrong driver files is my thinking. Well I'm going to flash bios and see if it helps.

Your card's probably busted

Are you booting a UEFI system?

What driver are you installing on what version of Windows?

Yeah@UEFI, but the old PC wasn't and as I said same result on Ubuntu as it is on Windows 7 and 10. Flashing GPU bios didn't change anything, I gave up. Unfortunate Windows doesn't support higher resolutions without a proper driver installed, or I dunno how to, as at least it could be used for desktop on backup PC... still can, but ugh @ 1280x1024/1024x768 res options.

I've had a couple cards that were happy working as a Microsoft Basic Display adapter, but the system would crash when I tried to install the drivers. Those cards were pretty much toast.

Now, I had a Gigabyte Z68 motherboard that did not like AMD/ATI cards. The system would crash a lot with a HD5870. Several years later I tried multiple different Polaris cards and that motherboard would not take to any of them. I also had a PNY GTX 460 that crashed a lot in lga1155 systems but it had no problems whatsoever in AM3 and lga1366 systems. It seems as if there are some motherboards that do not like particular cards.

Are you able to install the card into another system and install the drivers?
