Overclock P5Q-E & e8400

cruisinbeatz · 9 Sep 2008 at 14:39

Hi everyone, this question im sure has been asked 100's of times but I cant seem to find an overclock that works.

What Im looking is to take my 8400 to 4ghz below is my setup and ive serched over OCUK and google and cant seem to find a setup that works for me, Im a noob to the overclocking end of things so sorry if I sound a little silly.

Asus P5Q-E
Intel e8400
4x1GB Crucial Balistix 8500
Gigabyte 8800GT

I hope someone can help or list settings or something. Thanks in advance.

I'd like to know this also, I've managed to get 3.6ghz so far with 9 multi and 400 fsb. Any and all help much welcomed

There's plenty of threads around about this, but what i've found to be the biggest factor is the ram. Very hard to get upto 4ghz with any ram that won't go over 850mhz.

Hmm I see, anyone else got any help at hand?

ive got a e8400 at 4gig 24/7 at 1.375v

Gurusan If I were that way inclined I would kiss you, that worked a treat mate thank you so much. Your truely a God send. Thanks once again.

Sorry to revive this thread but I've been searching and googling, my spec is identical to this one however I'm using 4x1gb stick of corsair pc-6400 at 4-4-4-12. I can get 3.6ghz, well who can't? but I'd like to get 4ghz, the settings above aren't working for me probably because my ram is different, could anyone shed any light? I would appreciate it a lot.

Thanks

Try slackening you ram timings.

The above settings would have the OPs Ballistics running at 540MHz which is fine as they're rated to run at 566MHz, your kit can only do 400MHz at stock and an overclock of 140MHz is a tall order even if you slacken the timings & up the vDimm. If possible, you need to choose a memory divider/ratio that will allow you to clock your CPU higher whilst leaving your memory running at or around 400 MHz.

DavidQ · 21 Sep 2008 at 22:46

Which of the above settings should I change and what should I set them to, sorry to be a pain but I'm a total novice

FSB Strap to North Bridge: AUTO
DRAM Frequency: 1080

Basically look through the strap settings and see which one can give you the lowest DRAM frequency. At 450fsb the lowest will be 900mhz on the 400mhz strap. Or atleast that's what I get.

Im now runnign dominator 8500 ram and still cant get the machine to run at 4ghz stable, it will run at 3.9 which i guess is close enough, but everyone seems to be hitting 4 no problem.

Hi all,

my system is not able to boot on when i put Performance Level above 10. So this is minimal value when system boots.

My RAM is Corsair "XMS2" TWIN2X4096-6400C5DHX G (PC6400, 800MHz, CL5)

Newborn · 27 Oct 2009 at 06:57

At 450 x9, DRAM at 450 MHz, system is stable. Performance level = 10.

gurusan · 27 Oct 2009 at 08:33

When running 1:1 memory:fsb ratio you can't go lower than PL10.

Ok, thanks, i'll try 5:6 ratio =)

Newborn · 27 Oct 2009 at 17:36

system does not start, i put bus freq. 450 mhz, dram 1081 MHz, performance level 8. system starts only when performance level is 10 or higher.

gurusan · 27 Oct 2009 at 17:39

Try putting FSB strap to 333...also your ram is 800MHz CL5, it may not be capable of 1081MHz.....

how much vdimm are you giving?

Newborn · 27 Oct 2009 at 18:12

ok, i'll try. vdimm is 2.2 V
