aye he's right heat can be a cause. with random timed crashes depending how hot your gpu ovens get. airflow on that system could be a little different and its causing the crash.
My mining pc is no longer in the main house. Its amazing how much cooler the house is now.
Topic: Unstable Rig - how to diagnose (Read 1226 times)
I can tell you I have a couple of rigs that are particularity finicky. It was a cooling issue for me, I got to the point where I am running an a/c unit right into them, and they don't lock up anymore
I would go with PSU issue myself. Cards are running stock and its a random crash. If the temps are ok I would normally go with that
I would say its an overclocking stability issue, maybe one of those cards is of a slightly different version and cant achieve the same high clock.
Are you using 64 bit?
4 x 6870's
biostar 890FXA
hextec 1050W power supply
2 risers for the gfx cards
stock voltage/clocks
default fan control on ubuntu 11.04
i got 4 rigs running and this particular one always seems to die on me, hard crash 4-48 hours after rebooting. Problem is it runs for at least a few hours so im never able to catch it int the act.
Anyone know how to diagnose this problem? I'm looking for tips/tricks something beyond standard trial and error.. maybe some kind of monitor program, crash log file i dont know about, whatever.
