Just noticed on of my GTX260s had dropped it's clocks to 2D whilst in the middle of folding, and I couldn't get it to get back to 3D at all (I even tried playing a game). A reboot 'seems' top have fixed it, hopefully it'll not be a frequent occurrence. However the other fine was fine, not sure if it makes a difference but it was the primary card that dropped the clocks, and I'm running Win 7 x64 with 190.38.

Anyone had anything similar?
 
Ah good to know it's not just me then! Not sure why it would do this since the temps were only around 75C, and that was because it was on a 511 :confused:
 
As far as I know that was the first time it happened, but it now means I need to keep a close eye on it. It dropped the PPD from 6100PPD to just over 2800PPD on the 551 WU :( which is not good if it's running at that speed for several hours.

OT, but I have finally (if temporarily) removed your name from my threat list :D
 
Shame it won't be that high for long, now with these new cards I can enjoy playing games on my 24" with them looking crap on low settings :p

Fixed the issue, was the latest Nvidia driver, now on 186.XX instead. Shame though as CUDA performance has taken a hit. But at least I can play games in 3D clocks :D

Erm I had a couple, but nothing major. I had to roll back the drivers to fix it though. What ones you running?
 
I would try 186.18 drivers, since they are far more stable according to many on the web. Have you tried only running the Zotac in the top slot, then adding the second below? ie install the drivers with the Zotac then run F@H a bit, then add the other GX2 then reinstall the drivers?
 
Have you tried running any combinations of two clients on the cards, such as 1&3/2&3 etc?
 
Well you said you were having issues running four clients on the two cards. So Have you tried running one client on each, and swapping them around on the cores to see what's making it fall over? If this is entirely stupid .... then it's because I'm soooo tired :p
