Hey guys,
I recently got a second SAPPHIRE 6950 to go with my current one, the exact same cards. I completely removed everything AMD/ATI related ran driver sweeper and did a fresh install (More than once), but noticed that the performance was the same as it was while running one card. After I figured out you cant run crossfire in windowed mode, I realized I still had the same problem. I have tried almost every setting in CCC, tried multiple profiles..still having the problem where the GPU's wont run over 30% usage while playing SWTOR. Iv noticed that they are scaling pretty well, but they are just not performing like two 6950's should.
I ran Furmark and utilized 90+% the whole test, but when I ran Kombuster, I noticed that the GPU load was dropping frequently... it was terrible, for a while during the test I dropped to 0% load.
During Heaven the GPU's scale great and I get good FPS, but if I alt tab out to check temps/GPU usage % then tab back into the test, It drops the 2nd GPU and finishes out the test with only 1 card.
Iv tried just about everything I can think of, uninstalled/reinstalled everything more than once..GPU-Z show's that both cards are running on x8 2.0 stock speeds 820/1250 both cards same frequency..crossfire bridge connected all that good stuff..I disabled my PCIE link state threw windows.
SWTOR is the game that I play and Im running like 25 FPS in warzones...I should be smashing ATLEAST 50 FPS with crossfired 6950's...I just dont understand why I cant get over 30% GPU usage (or shitty framerates to be direct)
I had my processor OC'd to 4.2ghz and came to the conclusion that I tried everything I could think of, it has to be a PSU problem (so I think)..maybe the cards arent getting enough power. So I reset my processor back to its stock speed of 3.3ghz trying to free up some of the PSU juice. I still had the same problem (if not worse with the slower cpu speed). lol so I set it back to 4.2 ghz

My rig is:
*Asus 990x EVO mobo
*AMD FX-6100 3.3ghz stock overclocked to 4.2ghz with a CM Hyper 212 cooler.
*8GB (2sticks duel channel) corsair ddr3 1600mhz
*Sapphire Radeon 6950'sx2 crossfire (I wish)
*2t HDD 5200
*bout 6 case fans
*CD/DVD RW
*700W CM Silentpro PSU
*Win Pro 7 x64
*Samsung 1920x1080 monitor with HDMI
I really cant think of anything else, so I came to the conclusion that it was a PSU bottleneck, plus the Asus website says I need 900W minimum for my set up...I ordered http://www.newegg.com/Product/Produc...82E16817171049 (100W)...Althought I noticed the same problems when I reverted my CPU back to stock speed (which lowered the CPU voltage thus freeing up some of the PSU juice)?
Please if anyone has any information or ideas to help I would extremely appreciate it!!! here is a link of my last benchmarks
^Kombuster: (score:x1359)
^Heaven: Score 2695 @107 FPS
^I dont remember what my Furmark score was
PS: Im not a total computer skrub, but this was my first build, so im not totally fluent with everything there is to know in computer terms.
P.S.S: I ordered an SSD when I ordered that backup PSU lol figured I might as well...
Any Ideas or information would be greatly appreciated
