Topic: Running 4x 5830, problem with occasional crashes on main GPU (Read 985 times)
Sorry i did not explain more but my symptoms are freezing the computer in full. So i need to do a hard reboot of the system.
You could try to make a script to keep your miners restarting, when GPU crashes...
It's just a workaround for now.

I am also having the same problem but with stock volts and core. All the cards under full load are not going above 60c. See specs below.
I am running guiminer 20110701 win 7 64
Stock volts, 800/500 core/mem poclbm -v -w128
SAPPHIRE 100297-2L x4
MSI 890FXA-GD70
COOLMAX RM-1000B 1000W ATX (motherboard and 3 5830s)
ANTEC Neo power 430W (For 8 80mm fans 2.5 HDD and on 5830)
AMD Phenom II X6 1100T
G.SKILL Ripjaws Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1066 (PC3 8500)
when i drop to 2 cards PCIE slots 3 and 4 it works fine.
Any suggestions would be great.
thanks,

If it's crashing, it sounds like the overclock it too high or the temperature is too high. Lower the overclock until the system stops crashing. If it was nix you could setup a script in the case of a failed gpu.
I'm running 4x 5830 @ 950/300 but having a small problem with occasional crashes on the main GPU. Basically the graphics card driver crashes and reloads itself (it does this fine) but mining on that particular GPU will stop and not resume correctly.
Why does it crash? Is it because idle clock for memory is too low and windows does require the main GPU's memory to be "un-idle" sometimes?
Is there anyway to automatically recover from the crashed driver?
Thank you!

Possibilities:
Lower the aggression on that card alone, it may be too hard for the card to mine and draw the desktop at the same time.
If this is in a tower config, try laying the case on the side -- the 'main' card may be soaking up heat from the cards below it and overheating.
Lower that cards' GPU/mem clocks and undo any voltage changes, the card may not be as stable at high clock/high heat/low mem as the others.
Swap the crashing card to a different slot, see if it still crashes. It may be the slot itself.
Above all check heat and rejection rate; a higher than average rejection rate often means a card is overclocked too high or somehow defective.
... as for making the miner restart when the driver crashes, try using of the scripts floating around the forums that will kill and restart your miners ever XX minutes.
