hd 5870 crossfire problems (battle field 3)

[yawara2]

I am a korean. I can not speak english well.
Please understand.

MY SYSTEMS ARE DENEB 980, HD 5870 CF, WIN 7 64 BIT, CATAL 12.6, ASUS CROSSHAIR V FORMULA
MY 3D MARK 11 G.S IS 8700 (VALID) (99% LOAD ON BOTH CARDS)
LOST PLANET 2 BENCHMARK (80~99% LOAD ON BOTH CARDS)


BUT
WHEN I PLAY BATTLEFIELD 3 ====> (50~60% LOAD ON BOTH CARDS)
(THE PERFORMANCE RESEMBLES WHEN SIGLE 5870 PLAYS)

FOR THIS PROBLEM FIX, I HAVE DID A LOT OF THINGS (FORMATED, UPDATED, CATAL 12.1~12.6, VARIOUS BATTLEFIELD 3 SETTING, ETC...)
BUT THE PROBLEM REMAINS.

PLEASE HELP HOW THIS PROBLEM FIX.
I WILL WAIT YOUR REPLY.

do you have the CAP installed? (catalyst application profiles) and did you do a clean install by first removing the old drivers?

yes, i did. I have did a lot of things. But the results are same

You are cpu-limited. You would need at least an i5 or i7 at 3.3GHz to run your cards at full load. Even then, crossfire will never show 100% load.

There is nothing wrong with your cards or your drivers.

he said the results in BF3 resemble a single 5870, so its not normal.

Yawara2 please list your full system specs and what drivers you are using so we can try to help you.

Similar does not equal "same". If he has 60% GPU usage on both GPUs, he has greater performance than he did before. The best thing for him to do would be to give us data from FRAPS with both one and two GPUs.

MY 3D MARK 11 G.S IS 8700. I THINK THAT IS VALID.(99% LOAD ON BOTH CARDS, WITH CATAL 12.6)

ONLY WHEN I PLAY BF3 ===> 50~60 % load on both cards.
