Since then, Xfire has treated me pretty good..just popped an E8400 in yesterday, and broke 21k with my sig'd setup.

21300 with 2 x 4890 crossfired in windows7 @ only 3.69GHz with my sig, should be able to hit 22,000

I dont see anything wrong with that score...no doubt your SM scores are very high, which is what you should be concerned with for gaming use..You getting around 3.2k for your CPU..?

I know my GPU's appear very bottlenecked by the CPU, for 3D Mark testing. Just increasing CPU speed from 4-4.2ghz I gained over 1200 points in SM scores..and only 200 points in CPU...

That score is in windows7. XP is 13,000. GPU's not linked and my gpu score really gets drawn down like there is a bottleneck.

I was thinking maybe this is reason it will not link..... XP uses directX9 and Windows7 uses directx 10.1????/

Is this a fresh install of XP or the same install that you cleaned the registry?

Ok diamond had me flash both bios ,why I don't know, they were running 102 now I have 103. Now crossfire will not let me use it. It is not enabled. Both cards show in device manage and gpuz. I reinstalled drivers and ccc 9.6 version)

Could it be the 32bit OS your running perhaps?!

I do not see why?

I dont see any difference when running 32/64 bit for 3dmark benching. My score is about 1500 points higher in XP than in vista or W7. I think its due to having more CPU cycles at its disposal.
I am also having some major scaling issues with X fire. I only gained about 6FPS in crysis when I added my second card. I cant even break 50FPS using high settings on the default config with no AA in crysis 1600 1050 resolution.

Sounds like your CPU limited... heck even at 4.2ghz..my Xfire is CPU limited.
