Hey Everyone,

HAPPY NEW YEAR!!

So i bought three used Gigabyte 7970's... for cheap! So far, one of the three actually posts and is able to get into windows. The previous owner swears they ran months ago... but they were water cooled. He since put the stock coolers back on.... using thermal compound on the VRM's instead of thermal pads. I've taken the one operating card, cleaned it up... put some proper thermal compound on the GPU and Pads on the VRMS.

The card posts and gets into windows. I load MSI Afterburner and GuiMiner. As soon as i start to mine... the card INSTANTLY goes to 98+^C and core clock Rapidily fluctuates between 501 & 1050. The card does hash, but it's low. After about a minute... It doesnt feel like the card is putting out 98+^C.... so something isn't right! I've installed fresh drivers, i've tried both BIOS switch positions on the card and i'm thinking about reflashing. Any suggestions?

Thanks

Definitely sounds like a heating issue. The card is probably underclocking automatically to avoid overheating. Have you checked to make sure the fans are fully working and you have a solid connection between the heatsink and gpu?
