help OC E8200 on ASUS P5E

[zhaf]

Hi,

I recently bought my computer and I want to OC it as much as possible.
This is what I've got:

CD/DVD: Samsung SH-S203P

Case: Antec P182

PSU: Corsair VX 450W

HDD: Samsung SpinPoint F1 HD753LJ 32MB

CPU Cooler: Arctic Cooling Freezer 7 Pro

Memory: Crucial BallistiX PC6400 4GB CL4

Motherboard: Asus P5E X38 S775 DDR2

CPU: Intel Core 2 Duo E8200

GPU: Sapphire Radeon HD 3870 512MB GDDR4

I've read the C2Q/C2D OC sticky and managed to OC it to 3560MHz (445x8). I increased the vCore to 1,35V and mem voltage to 2,2V. I set the timings to 5-5-5-15. It runs stable with PRIME95 torture test for about 3hrs. When I set the FSB to 450 PRIME95 will fail within 10min. My temps are ok I guess. They're: (taken with HW Monitor)
Core0: 43 idle/56 load
Core1: 42 idle/54 load

I haven't increased the northbridge voltage yet... mostly because I don't know what the safe voltages are.
Do you think that I can get much higher with my cpu? I've seen plenty other OCs go ~4GHz.

edit: oh and my ram is at 1:1 atm... so running at 890MHz. A strange thing is that it seems that I can only overclock the ram more as there aren't a bios setting that allowed me to underclock my ram.

You've seen plenty of people with E8200 hit 4GHz? That's running 500FSB on the mobo, which is quite rare for most practical OCers.

Raising the NB voltages could help, as well has raising the fsb voltages. Just increase it around +.1V-.2V.

And as for your edit, the lowest setting is 1:1. Of course you can't go any lower, unless you have an unsync option, which you don't.

Ok if I said plenty I'd be lying. But well I googled that and there are some people that have had luck with their overclocks.

hm... I can only type the voltages as there aren't any drop down lists or +/- buttons. Do you happen to know what the standard voltage is for FSB and the northbridge? Do I have to care for the other bios settings?

Normally standard would be 1.4V, so you should be setting it around 1.6V.
