Windows 7: 5770 cf problem

5770 cf problem

ive been having a problem with crossfire performance recently only started happening the other week

my cf is only slightly more than a single 5770
and im judging this by games with great crossfire support for my 5770's
(COD MW2 / Farcry2)


okay so the problem is my second gpu is under the most load during 3d mode
example looking at msi afterburner when ive been playing a demanding game will show first gpu at about 90% and second gpu under 100% load
and this is resulting in low performance


Ive tried reinstalling window, tried all the drivers 10.4 -10.7 (correctly removing them all)
im baffled
sometimes when i install the drivers or disable cf then re-enable it will work showing under even load when gaming , resulting in HUGE fps boost then it will just start acting up again ,

Ive tried both gpu's on there own
in both the pci slot and they are both fully working

this is getting so frustrating


edit-- heres an example
playing cod mw2 maxed @1920-1080

im still getting gr8 fps average about 150fps but i was getting higher when both gpu's were @ 100% like they should be

and when playing farcry2 ive lost 20 fps and thats much more noticable because im hovering around 40-50 fps where as with vsync enabled i never used to dip below 60 fps

Sorry I don't have an answer to your problem but I was wondering if you could kindly post what utility/program you use to display the graph information you posted (not the screen capture).

I use CF w/XFX-5770's but don't have a clue of what the GPU's are doing at any given time.

Thanks.

just been playing mafia 2 demo and getting good fps then the first gpu started using less and less resources killing my fps

look where its circled still a bit of an uneven load but i was getting gr8 fps
then
fps just started dropping leaving me with a crippling 20fps

could this be motherboard related problem
or maybe even psu one?

yes.....


anyway...
i was seriously think of getting rid of one of my cards
but i just thought my last option to restore my bios
to default and that has fixed it .
it seems as though as something was disabled what wasnt allowing me to install certain drivers
because after resetting to default these drivers installed

and now both gpus are under equal load and giving me stable performance
i dont feel so much like throwing my pc out the window now


p.s- but now i just remembered i forgot to save my overclocked setting before i restored my bios
nooooooooooooooooooooooooooooooooooooooooooooooooooo lol
