[HELP] XFX DD 7950 FX795ATDJC - Keeps throttling.

[Mk2vr6]

I can't get anywhere near 600kh without it throttling after about 2 mins and dropping down to next to nothing.

Running a dual setup with a 280x and can achieve 750kh on that no problems.

I have tried all sorts of configurations in the batch file, and the only way I can get it to run constantly is to reduce TC or GPU clock down to about 850.

Anyone else have any experience with this card?

Thanks

I was looking at maybe a faulty BIOS. Thanks for the link. The GPU is new and under probably 48hours use old.

It seems as soon as it gets up to operating temp, whether that's 70'c/100% fan, or 75'c/85% fan for more than two minutes producing more than 600kh/s it throttles and then the screen will blink before it slows right down to a halt hashing at aroun 50-70kh/s. At the same time CGminer stops updating, and after 60 seconds or so declares the GPU sick. If using CGwatcher, it will just restart CGminer over and over.

I'll have a look at that link now.

Thanks again.

Any idea if it'll work for a 7950?
