Anyone had their GPU drop to 2D clocks

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

Did you notice an abnormal amount of EUE's when this was happening
ive just added a second gx2 to my pc and installed win7 64bit
ive noticed my primary gx2 seems to have severly slow folding on gpu1 and gpu seems unable to do a full run of any 787 pointers
ive reduced the clocks on it to see if that resolves it but was still getting the same issue's
 
Erm I had a couple, but nothing major. I had to roll back the drivers to fix it though. What ones you running?
 
driver version 190.38
it seems to be fine with 1888's
ive got 4 clients running 1-4 its clients 1&2 causing the prob's
ive just sync the clocks using evga presision and set them to 1750 shaders instead of the 1800 i was able to run on just the one gx2
im thinking that the new one a zotac version cant take the high shader clocks my older one can
im thinking although the older card is still in the pci slot closest to the cpu it has now taken on gpu 2 and 3 switches when running multpile gpu clients
where as the new card in slot 3 as i have 4 has taken on swiches gpu 0 and 1
 
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
 
well a quick test there by turning off 2 of the clients has shown me that its the older leadtek card falling over
However ive just checked on the off chance and noticed phsyx was enabled ive disabled that now and hope thats all that was causing it
