New AMD 6950 Issues

post #1 of 14
Thread Starter 
I seem to be having a pretty major problem with the new desktop I built yesterday. I have an AMD Radeon HD 6950 with the Catalyst 11.5a Hotfix drivers installed, and I can't play a demanding game for more than a few minutes. After just a few minutes of playing my monitor goes blank and says input not supported, often times the game will lockup completely. This happens every time I try to play The Witcher 2, Just Cause 2, or Metro 2033. I've been monitoring my temps and they seem to be very acceptable, so I don't believe it is an overheating issue. I also just tried reverting back to the 11.1 Catalyst drivers, and I'm still getting the same problem.

Does anyone have any ideas on what might be causing this problem, or what I can do to fix it? I still have about 25 days or so to RMA the card for a replacement, but I want to do that only as a last resort.

Sounds a lot like an unstable overclock / clock speed? Have you flashed your card to the 6970 bios? Sometimes the 6950 ram is not able to cope with the 6970 timings, and the card will become unstable.

Can you check your core and mem frequency and post it together with your voltage settings? cool.gif

This problem occurred the first time I ran Just Cause 2, right after I had finished installing the card and the drivers. However, I did attempt to flash this to the 6970 but for whatever reason the shaders did not unlock. My current core frequency is 800 and my memory frequency is 1250. I'm not sure how to check my voltage settings, could you perhaps point me in the right direction to get that?

I tried to underclock the card a bit to see if it would be more stable, but I got the same results.

Now im not an ati guru, but to me it sounds like a clock problem smile.gif

I would download msi afterburner, and then unlock "unofficial overclocking", which can be done in your configuration .ini file. After you've done that, you should have full voltage control over your hd 6950, and you will be able to read the current voltage besides the slider. then i would try to feed it more voltage: say like 0.5 volts extra. The card should def. be able to handle this, and it will let you check if it's an instability problem caused by clock/voltage ratio, unstable clocks etc .. If this doesn't help, then you might be experiencing some kind of driver problem. Have you ever used nvidia drivers on that hdd format? If so, then they can potentially conflict with your amd drivers, if you have forgotten to uninstall etc .. smile.gif

sorry it was not an .ini file, it's a .cfh smile.gif

I was able to get the voltage control unlocked, my current voltage reads 1100, I don't know a whole lot about these things, so would it be safe to assume that 1100 means it's at 1.1 voltage?

Yes 1100 will be in milli volts, so it is 1.1 - howewer this is the standard voltage for ref. 6950s, so it puzzles me that yours is unstable. Try increasing the core voltage to 1150 or 1170. This should rule out the instability due to wrong clock speeds, as it should be enough to get it stable. If this doesn't improve stability, it might be either a damaged card, or you may be experiencing driver problems/conflicts cool.gif

OR your chip may just down right suck, and need 1.3 volt for 800 mhz, but this is unlikely, and mostly meant like a joke lol tongue.gif

I increased the voltage to 1150 and I still got the same issue. It's looking like I may have to RMA this card. I've tried many different driver versions, using driver sweeper to remove the other drivers.
