Hello good fellows of TH, I need your assistance troubleshooting my 6870 xfire! I recently put two hd6870's in crossfire they both are running stable under Furmark and all games--Crysis 3 Beta Dishonored Just Cause 2-- although I noticed that GPU2 was only running in performance state 2 at 775Mhz Core and 1050Mhz Memory @1.100V, even though GPU-Z, GPU Shark, and Furmark all listed GPU2 was under 99% load. It should be in performance state 3 at 920Mhz Core and 1120Mhz Memory @1.231V. Cards are running below 80°C even under max load. Can anyone possibly help me with my issue please?
AMD Phenom II x4 955 Black O.C. to 3.6Ghz
16Gb 1333Mhz DDR3
850W KingPin Xfire ready PSU
Asrock Extreme4 990fx Mobo bios version 1.80
HIS 6870 1GB (GPU1) adapter slot 0 Video output
Asus 6870 Direct C.U. 1GB (GPU2) adapter slot 1
I have already tried to;
-Overclock both cards and voltages using various values on CCC, and Trixx
-Use older/newer versions of CCC, Mobo Bios
-installed CCC Application Profiles CAP 2
-ULPS is Disabled
Thankyou in advance to any tips or help you can give!
