ATI Crossfire issues, 1 GPU stuck at 400/900 [ATI 5000 Series]

post #1 of 4
Thread Starter 
Hi guys, I have a 5970 and 5830 both overclocked, and in tri-Crossfire totally for E-Peen. That aside both individual cards when run alone run pretty darn awesome, my 5830 overclocks to its max allowed with the BIOS lock, which is 875 / 1200 , and my 5970 overclocks to 825/1225, but I keep it at 800 / 1200 because its stable. anyways, i havent noticed this until iv started folding.. When in crossfire mode, GPU 2 on my 5970 drops to 400/900, and sticks until I kill MOM.exe and CCC.exe Now this doesnt happen when its not in Crossfire mode with the third card (i think) and disabling Overdrive doesnt help after the problem starts.... so is there any long term fix to this? Its getting annoying, my PPD is dropping 4-8K PPD

i think that your 5970 throttled to prevent dammage , as you're folding , it's probably caused by overheat

just watch you're vrm's with gpuz, they must not be higher than 115°-125°c

Yes, the 5830 is a Cypress LE GPU,and the 5970 using Hemlock is actually a pair of Cypress XT GPU's all are Cypress GPU's therefore Tri-Crossfire is what this is.

While folding none are above 100.C because of the amount of ventilation I have going for these cards.
