Try over clocking the pci-e link.

is this coming up as binary code for everone? doing blend test now. when i was ocing the 925, i found that intelburntest found instability much faster in 10-20min than 45m to 2hrs of blend from prime95. what if i did them at the same time, would that help or hurt?

i ran both at same time, no crash after 20-something, then i set the bios setting back to default. realized that at 3.4 on a quad core, i should not have a bottleneck, especially if i didnt have one on a 925. so any other thoughts? o and i tried overclocking the pci-e bus it started windows without display at 110, bringing me to manually shut it off

You need to just keep things at stock.

because its still bottlenecking at stock 3.4. which shouldnt be happening. so im curious if that mean there is something wrong with the new chip i got, not 965's in general. does anyone have any of these issues with a 965?

Phenom II's have problems handling High end GPU's.

They are bottlenecked easier then nehalem.

and a 4870X2 is simply to much for the Phenom II to handle.

i personally own a Phenom II X4 955 C2 3.9GHZ @ 1.55V and it chokes on a pair of GTX 280's

@OP

Your problem is your resolution. I can almost guarantee if you were at 19xx by 10/12xx you would see 99% usage (give or take 1-3% drops). But because you're only at 1680x1050, you'll have to max out every game you play with the most AA/AF to see it do 99%.
