3 7970s Crossfire, not being utilized - Page 2

post #11 of 34
Make sure you have ulps turned off especialy if your overclocking. Can you try just one 1080p monitor for us and see your usage? May sound dumb but it will give you a better idea if the cpu is bottlenecking ur gpus

Even My HD 6990 get Bottlenecked @ 1080p by 2500K @ 4.8Ghz. Best thing to do is sell one while you can.

you have three 7970's there will be no way to use them up to 80% on all video cards. you will have a bottleneck on your processor with 3 cards

An easy way to see if your being bottlenecked is by running 3dmark11 or vantage then run it again with your i7 overclocked a little more and compare the gpu scores running the same clocks as before. If your gpu score increases with your gpu clocks the same, that means your cpu is bottlenecking you. If that is the problem then try overclocking your i7 as high as it goes safely.

It can. A 2500k does NOT bottleneck a 6970. I ran FOUR 6970s and had 98% GPU utilization on every GPU in BF3. It's all about tweaking and optimization.
