Hi all!
I am building a new PC ,here are the main features:
Motherboard Gigabyte EX38 DS5
Intel E8400 (3 GHz, not overclocked)
Memory-G. Skill PC8500 (g 4x1Gon but as XP32, I do recognize that 3 GB)
Food-Corsair TX650W
Graphics card: two Sapphire HD4850 connected in Crossfire with the two bridges (I have not forgotten the external power supply)Radiator-processor (it can serve) OCZ Vendetta 2
My problem is that when I run the test benchmark Crysis, I am at 32 fps with a card (when I say a card is not that I disabled the crossfire, but I have other outright withdrawn card) and when I activate the crossfire I am a 28 ....
I reinstalled the last Driver 8.11, but it is not moving Catalyst (incomprehensible), it does so that drivers can not activate the crossfire ....
So I tried to install the Catalyst 8.10, it works (with drivers huh 8.11) but still the same problem ....
With drivers on the original CD (Catalyst 8.4) always the same ....
I tried each card individually on each port PCI-E, with each cable feed, and everything is working correctly ....
I do research on the net, many assemble have this problem because of their chipset which bridles PCI slots, but as I have an X38 I'm not concerned theoretically ...
Thank you in advance for your help!
