Decreased performance after installing second 6950

post #1 of 8
Thread Starter 
These are my specs

Phenom II X4 980 @ 4.1 (20.5 x 200)
M5A88-V Evo
2x4 GB Corsair Vengeance @ 1333 9-9-9-24
6950 1 GB + 6950 2 GB in crossfire
850 watt corsair PSU
Soundblaster audio card
7200/320gb WD

Once I noticed the decreased performance in Battlefield 3, I figured my CPU was bottle necking the 6950's in crossfire. But then I also noticed a decreased performance in lighter games such as Modern Warfare 2, League of Legends, and Starcraft 2.

I reset everything back to stock and increased the CPU/NB frequency to 2600 @ 2.5v, didn't really do much.

So I'm still scratching my head trying to figure this out. Any insight?

Some games perform worse in crossfire, could be a driver issue, could just be the way it is. What drivers are you running?

Latest drivers, and I wouldn't think so because it's like that in pretty much every game I play.

They're fine, 70-80 under load. Both are active.

yea anytime your using crossfire you should install the newest caps and you are using a crossfire bridge right ?

download the AMD Catalyst Application Profiles and install them then reboot and see if your issues are fixed might need to try a differt driver.

I installed the recent caps.

It seems like it might have made a minute difference, but the problem still persists frown.gif
