My PCI-E Maximum Bus setting is at 4x instead of the possible 16x I could be getting. Usually it runs at 8x for some very awkward reasons, and sometimes a luck 16x. I noticed the drop to 4x when i oc'd my CPU to 3.8, and maybe this is the cause of my bottleneck in games like cod5?? Is this just a glitch or? I get the same reports in ATI system information and Cpu-Z, but in ATI it says my linked display is at 16x, and my primary at 4x
On CSS stress test im only getting around 350 fps every setting maxxed at 2048x1152, on COD5 I get serious FPS drops during zombie survival. If i recall before on css at 3.6 with both busses running at 16x, i could get around 400 or even higher.
I might be possibly getting a 5850 or 5870 but I do no want to waste my money on a unnecessary card, if the cause of my performance issues are due to the pci-e running at 4x. Also to save my money for a hex-core and Rampage III Extreme
One other question, is the Hyper 212+ in PUSH PULL better than the V8?
Here are my specs
CPU: Core i7 920 C0/C1 @ 3.8ghz
RAM: 12GB Patriot DDR3 1600
VID: Dual ATI Radeon 4870s 512MB 800/955
MOBO: Asus Rampage II Extreme 1504 BIOS
PSU: 1000W Corsair
Cooler: Coolermaster V8
OS: Windows 7 x64 Ultimate
I've already fixed the problem, i cleaned the contacts of both my GPUS including the CF bridges and the PCI-E connectors. Also moved 2nd card to first slot, and 1st to 2nd. It worked, and wow, the bottleneck i had, was just amazing, i thought my friend with a 5850 was getting more fps than i was.
