GPU Core Crashes (Or at least it doesn't work)

[Ikester]

Thanks for the feedback folks! I tried memtestCL using default settings and found that the card fails the "Random blocks" test every 3-8 iterations. Here's the test result summary:

Code: Select all

Does that mean it's definitely bad or can the driver be implicated somehow?

Speaking of drivers, just where would I find version 12.8? As noted in my first post above I installed "12-10_vista_win7_win8_64_dd_ccc_whql_net4". In checking back at the AMD site, I also found the latest beta drivers:
"AMD_Catalyst_12.11_Beta4_dotNET4". Worth a try? There's also an "AMD_Catalyst_12.10_CAP1" but don't think this is a driver install.

Just to add to my confusion, at the Gigabyte site(My card is a model GV-R545-1GI made by Gigabyte) I found "vga_driver_amd_vista(win7)_8.881" and " vga_driver_amd_vista(win7)_8.982" versions (only two versions listed for my card besides the link to the drivers @ AMD's site.

If I do decide to try other drivers, what's the correct procedure? Do I just install over the existing or would I first uninstall? If the latter, just how is a driver uninstalled? Sorry if these are basic questions, it's just that I've never run into anything like this before.

If it were my system, I would treat i like a genuine hardware problem with the VRAM (but I don't know the driver issues so I might not be right).

You'll find more information here.

It seems bugged:

You can try VMT as a "second opinion".

Interesting reads! Thanks for the insights. By 'it' I now know you mean memtestCL. Since the devgurus topic concluded over a month ago with a seemingly flawless fix, why isn't the corrected version of memtestCL available yet ... or is it and I'm just not looking in the right place perhaps?

So what's VMT?

We are aware of this problem and will update the binaries soon.

[Rolo]

Yay! (I like memtest* better)

I take it a Win8 compatibility fix is also in the works? (someone elsewhere reported that it didn't work)

[Ikester]

Since a debugged memtestCL isn't yet available, I tried VMT and it doesn't find any errors. Mind you there are many options and I can't say I tried anything beyond the defaults.

I'm assuming the card is good and that the failure I was getting with memtestCL is a false positive. I did find version 12.8 and followed instructions as per the first post here. After all that, the card still fails. Dunno what to try at this point. Time to give up on my GPU I suppose.

Win8 works, the problem is getting the right video drivers and disabling IPV6.
