ok, got the 2nd GT.
I enable crossfire (crossfirejack), start 3dmark 05 and got aprox 3-3500 extra points. (everything works just as they should in crossfire)
start 3dmark 06, the results are the same as just one card. (got the first test (return to proxycon) to run as crossfire (almost double FPS, and noisy fan
) but the next three showed no improvement)
aquamark shows no increase. neither does games.
in 3dmark i can hear the noisy stock fan rev up, so i know it is using both cards (not in 3d06 though)
I have tried these drivers:
6.4 beta x1800gto crossfire (says on info it supports 2 x1900GTs)
6.5 nforce 4 (check first post in this thread)
6.6 conroe edition (found on another forum)
6.7 Cat. and omega
6.8 Cat. and dhzeropoint
with all 3 Cat. AI settings
games/bench tried: (no change in performance)
*Oblivion
*X3 The Reunion
*FarCry
*Prey
*Just Cause demo
*Dark messiah Demo
*Halflife 2
*3dmark 06 (except that 1 time i managed to run the first test in crossfire)
games/bench tried: (that actually gives 80-100% improvement in fps)
*3dmark 03
*3dmark 05
searching for any help i stumbled across an old article on the web (from the first introduction to crossfire, x800 was new etc.) that said 3d mark would register frames from both cards (AFR) but it wouldnt work proporly since you would only see half the frames on your screen (because you don't have a dongle) but in 3dmark 03 and 05 i visually see a difference b4 and after crossfirejack, so i think it doesnt quite apply
I have also tried copying the game executables and renaming them to AFR-FriendlyD3D.exe / 3dmark05/03.exe / FEAR.exe to no avail.
bios setting tried with Auto/single/dual normal/fast setting, no change.
why is it that 3dmark uses both cards, and anything else doesnt?
Please come with any info that might help.
