HD 6950 Freezing in games

[Makuab]

I recently purchased a 6950, and have noticed since my games have been freezing to the point where I have to open task manager and end it. I have the current drivers.

Are you overclocking anything? What is your PSU?

 

[Makuab]

CPU is OC'd
dont think card is, I have a 750TX from corsair.

Its been flashed up to 6970, would that affect it?

Thanks for that important bit of info.

^_^

Flash it back or underclock it and see if it returns to stability.

this.

yes.

That is most likely your problem. Alot of the times the cores/shaders are locked down because of a defect or can't handle high enough clockspeeds, ect... While others have had success, you can be sure there are a high number of 6950's with the shaders disabled for a negative reason.

Switch back to the 6950 BIOS and test it out if you haven't already. Also a flashed 6950/6970 uses significantly more power than a stock 6950, make sure your PSU is capable

Theres nothing wrong with what you did. Dont switch back to your old firmware. you need to go to ati overdrive in catalyst control center and enable it. then you need to change the power to +20%. It sounds like your trying to run the hd 6970 setup with the hd 6950 power. Increasing the power is necessary to make it run correctly. More unlocked shader cores means more required power.

Its your flash that messed things up like the others peepz said.

See if you can downclock to stock speeds and see how she runs. Also if you have to take your CPU to default stock as well.

Your PSU is fine, your card is getting warm either the GPU or the VRAM.. thx

 

[betasub]

alienate & prowlex have good advice. Test with PowerPlay at +20% to ensure this isn't the problem for your card. If the problem remains, flip the BIOS switch and re-boot to run your card with the stock 6950 BIOS (shaders/speeds/power/voltage).

I had this EXACT problem on my new rig with the HIS HD6950 2Gb. Every game would lock up with looping sound every 20 mins or so and eventually after 5 mins the screen would return to the desktop (if i pressed windows key).
Good news is i think i found the solution. Rather than disabling the realtek drivers like many solutions suggest, just install the 'default' HD audio drivers (NOT the ones integrated with your motherboard drivers). Dont worry this installer removes the old ones.

I had to restart twice for the uninstall/install and ever since it has been total smooth sailing. Honestly i tried about 20 different fixes for this problem and i am so happy its all over. The only other step i took that 'may' have helped was lower the quality of sound output on the realtek utility. Hope that helps.
