Hi,
I recently upgraded my computer by adding a second 5770 card, here is the spec:
Here is the spec:
CPU: INTEL Core 2 Quad Q9300 2.50GHz 6M @2.5Ghz stock
GPU1: Sapphire ATI Radeon HD 5770 1024MB GDDR5 PCI-Express
GPU2: XFX ATI Radeon HD 5770 Single Slot 1024MB GDDR5 PCI-Express
RAM: (6GB) CORSAIR 4GB (2X2GB) DDR3 1333MHZ 9-9-9-24 + CORSAIR 2GB (2X1GB) DDR3 1333MHZ 9-9-9-24
MB: (P5E5) ASUS S775 Intel X38 DDR3 ATX
HDD: 300GB Velociraptor
PSU: 650W
Followinng the instalation and a driver + CCC update I didnt get any improvment in FPS in any games I tried (3DMark11 refused to work on my pc due to some settings bug)
GPUZ showed crossfire enabled on first GPU screen and disabled on the second, I gather thats normal, but the second GPU always has load of 0%. Tried it on several games (Portal2, Gragon Age2, Witcher 2). Drivers installed 11.5.
I Then uninstalled CCC as per instructions and manually uninstalled drivers for both graphics cards in device manager. This made Win7 install 11.2 drivers automatically. Curiosly Crossfire with Win7 drivers (no CCC installed) shows as enabled and the 2nd GPU does show load, but everything runs 33% slower.
Installed CCC 11.5b drivers. GPUZ now showing driver version 11.5, not 11.5b. Got the same issue, Crossfire is enabled, but 2nd GPU never comes under load. There is no difference in game FPS with crossfire enabled or disabled.
All tests were done fullscreen and both PCIE slots are running at x16.
Dont know what to do now... Maybe flash the BIOS?
