NANs detected on GPU

post #1 of 10
Thread Starter 
Hey folks I'm getting this error on my GX2... Any idea what it means...?

I have looked around and tried a few solutions:

Delete work folder
Reset client config
Run in compatibility mode

Managed to get one core going again, still having problems with the second.

I am running vista (my sig rig)...
This is on 5766, 5768 and 5765 WU's (that I have seen).. The core that is running is currently doing a 5772 (all are 353 point WU's).

Code:
[17:32:42] - Expanded 46690 -> 252912 (decompressed 541.6 percent)

What do you guys reckon? Possible batch of bad WU's?

Even when I reset to stock speed it will just error straight away...

Is there anyway to stop getting particular types of WU's?

I can't sit here babysitting it it all day, checking every 5 mins to see if it has got another of those bad WU's.

I had a run of these with 6800 wus.

I deleted the wu, temp and work files. Fortunately, it uploaded other WU apart from 6800s.

I found changing the clocks didnt help. I guess its a waiting game unfortunately

My 8800GTS has been crapping out on every single 353pt unit it does. I have tried underclocking too.

It folds any other unit just fine, even with an overclock.

There is something about these 353's

My GTS 250, GTX 260 do just fine, but for some reason my 8600GT hates folding lol. Just set it up the other day (even though PPD sucks, but power draw is minimal so meh) and it has finished 7 WUs and Failed 9... So yea I know how you feel

Well I posted this at the F@H forums, and they checked those 353 WU's, turns out they are fine?

Clearly not.

Edit:- Just got two more 576x WU's... I'm getting fed up with this now, I have shut it down. If its not going to fold why waste the electric.
