Hi folks, was wondering if anyone has had their GTS250 1GB suddenly go "unstable_machine".
This surprises me as I am completely unable to crash the card regardless what I throw at it. I game on it, fold on it, fold and game at the same time, but I couldnt figure out why it all of a sudden it'd just sit there idle, waiting for a WU.
 
Since this is my work rig, I've just not been overly concerned about it. If you can think of anything to check out, let me know.

The 803x WU you mentioned in the other thread could have caused your GPU to go unstable.

Yeah, I picked that up reading. Thanks for confirming that.
 
Looks like Stanford's going to loose a LOT of support very, and I mean VERY quickly, if they remove a lot of old, but still extremely powerful hardware like this.

Never really had that problem with my old GTS 250 1024MB.  Some units didn't really like my OC, but I've been known to push that old card a lot.  I've got a good vanilla card that'll easily cruise 800/2000/1100, 68C.
 
I remember being disappointed by the GTX 275 cause my 250 makes almost as high a PPD.
 
But as for suddenly going unstable, never noticed it.  Mine would hit a unit that didn't like the OC and go unstable, then downclock to safety speed and crawl.  Some of those GPU units they're throwing in there are murder anymore.

Ok, the 250 is still churning out bad WU's. Does one or two, then fouls 5 in succession. Its not picking up the 803x wu's

Got some failed Project 5770s and 5768s on my GTX9800+ recently, also due 'unstable machine'.
Got the latest driver.
Thoughts? Is this related?

I'm fairly certain it's caused by the drivers. I updated my driver to the 295.73 a few days ago and got the same issue. My 460s would finish a few 803X WUs, and then just fail to start 5 in a row causing the client to go to sleep until I restarted it. I solved it by installing an older driver. I've been trying the 290.53 all day and so far it's good.

Thanks for the heads up johny24. I'll look into this on my 250 and get back if this works or not.
