Title: 2 7590s and 1 loud and hot Post by: Igotcha on May 23, 2013, 10:26:32 PM Hi,
at the moment I have 2 Sapphire 7950 in my rig, third card is on the way. Both cards run in PCI-E 3.0 x 16 @x1 2.0 slots with non powered riser cables. The card on the first slot was from the start louder and hotter than the second card and the air exhaust is extreme related to the other card. I use cgminer with these settings -I 13 --auto-gpu --auto-fan --temp-target 80 --gpu-fan 40-90 --gpu-engine 1100 --gpu-memdiff -150 In cgminer both cards run at around 580Mh/s and with 78-80°. Should I resend and exchange the one card? Title: Re: 2 7590s and 1 loud and hot Post by: greaterninja on May 23, 2013, 10:51:24 PM for 2 x 7950 sapphire 580mh/s seems good enough at 78-80c
my 2 x powercolor 7950 run 540+mh each ~78-85c Title: Re: 2 7590s and 1 loud and hot Post by: redtwitz on May 23, 2013, 10:56:28 PM How are the cards mounted? How big is the distance between them? Did you try interchanging the cards' locations?
