this is pathetic... i've been trying to overclock it, but it seems that it wont overclock...
i have p5q pro + e8400 (e0).

i just want it up to 4 ghz

my problem is that game called mohaa freezes sometimes in the main menu, or in the start, it might freeze too before connecting to server... i guess its unstable oc then?


i have tried something like 1.33v for VCORE but wont work, and max. fsb 1.30v, dram 2.10v, sb 1.30v and nb 1.30v highest volts i have tried... should i increase the pll voltage? or something? what voltages would work?!!! help me..

and by the way. 1.25v worked months ago for VCORE..
and i ram runs 5-5-5-18 (450 mhz, +890mhz in bios) lol

HELP! how to get it stable and fast working....

might it be because high temps? i have usually under 50c with 1.30v (vcore).... mb is around 45c. i dont know about nb, sb or ram.

Can you post all your bios settings?

Edited missed the second post...

that will take a while, but okay then. going in bios now!

Also what Bios ver are you running. I have heard of people having trouble with p5q bios with certain brands of ram. I am use a modded bios that I got here:
http://www.xtremesystems.org/forums/...d.php?t=200109

It is easy to flash with a p5q all you need is a usb jump drive.

i am currently running my E8400 at 1.408vcore and its stable in prime95 for 3 hours now. 445x9 max temp was 56C. i cant believe my cheap PNY ram is stable at 890mhz at 2volts.

i can do it with a cd-rom too, and i have newer than default bios version, its probably newest, NOT SURE. but yes...

Is anything else OC'd at all, like memory, or your GPU(s)? Make sure to OC one thing at a time, so when something goes wrong you have a better idea of which piece of hardware is the culprit.

memory is, omg.... of course if i have oc'ed cpu.. gpu not, but i have overclocked it sometimes, but not when i play now this game.

my divider is 1:1 too. and 1.5 is very high IMO? 1.4v not needed for that...

w t f

should i test this modded bios: p5q pro 2102m.rom

What cpu cooler are you using?

What are you using to measure your temps while you stress test?

Heat plays a HUGE factor in getting your system stable when you're overclocking. You're voltages are not insanely high but if you are using the stock cpu cooler while you test it out that may be the problem.

Grab a cooler and your cpu will thank you for it. Seriously.

It is a little high and I had to add cooling to the NB to do it, but a lot of people run their Blood Irons there. I recently put in this 8400 and have not lowered it to try yet. I needed it to get my previous 6850 close to 4ghz though I may not need it for this.
