Speed up a e8400?

post #1 of 38
Thread Starter 
Hey guys, so im working on my freinds rig since its having some issues with games and such

Heres his specs
Intel E8400
ASUS P5N-D LGA775
A70 cooler
EVGA GTX 260 (216 core)
3gb ddr2 (800 i believe?)
500gb seagate 7200rpm
680 watt bfg psu

After trying out some programs and games it seems that his cpu cant keep up with the graphics at stock (bfbc2 gpu @ 70-80% usage and cpu is at 92-100%).

He doesnt really have money to spend on a new parts (brothers hospital bill) so what would be some options to go about about speeding up the system as a whole or is there a way to OCing the cpu on a non OCing board?

Thanks!

The board should be able to do a mild overclock no problem.

People have hit 4 Ghz on that board with that CPU so the motherboard should not be the limiting factor here.

You should be able to change the bus speed/FSB (not bclk for LGA 775) no problem, the multiplier will be locked on that chip because it is not an extreme edition CPU.

You can get 3.6 @ 400 fsb safely without touching any voltage with the e8400

1.45 Volts maximum, I don't know about that cooler but I'm guessing you won't reach maximum voltage before thermal limits.

Yeah i've easily gotten 3.4-6ghz with just a basic desktop board on my 8400. It's a fantastic cpu even today. Keeps up with anything you throw at it even a 580 @ 1080p.

An E8400 shouldn't be bottlenecking a 260. What resolution and options is he playing with?
