Asus P5K E8400 Overclock Help Required.

Wac · 18 Jul 2008 at 12:53

Hiya all,

I'm looking to give my PC a bit of an overclock this weekend and wondered if I could get some advice on the potential overclock I could get, and also what settings I need to change in the P5K bios to achieve this.

I'll be using the stock intel heatsink that came with the E8400, please see below for my system spec's.

Oh, I must also mention this is my first overclock.

Any advice is very welcome.

Thanks,

Adam.

Hmm, if it was a Q6600 i could give you exact settings.

Search google for Clunky's P5K overlcocking guide, it's brilliant, though i got my settings from experiementing and several other sources, but the settings he gives work fine.

(P.S. I though i was the only idiot in the world to pay big money for the P5K premium and a Raptor

)

Actually, here's the link, an OC guide, and the P5K specific one:

3.6ghz is usually achievable on stock volts and you will see a nice improvement in speed too! all you have to do is increase the fsb bit by bit and test for stability with something like prime 95. i dont know how far people usually go with the stock cooler but i recon 3.6 - 3.8 would be ok

Try these , work fine here, but i can use a 9.5 multi

Thanks for the info, but am I right in thinking this will overclock to 4GHz? That seems a bit too fast for a stock cooler, I was thinking 400-600 extra Ghz. I may be wrong, as I said I'm new to this.

Thanks,

Adam.

replace stock cooler if you intend to overclock.

Wac · 19 Jul 2008 at 09:56

Okay, what would you reccommend?

I was told that I could overclock with the stock cool, not by much maybe 400-600 extra GHz.

Thanks,

Adam.

i have a artic cooling freezer 7 pro on mine and its fine at 4ghz, i havnt tried it at higher overclocks yet. if you want to spend more go for a tuniq tower or a true 120

edit : just check that whatever you choose fits on your m/b first!

WJA96 · 19 Jul 2008 at 10:17

The stock cooler is used on CPUs that run upto 3.6GHz, so it will handle more thermal output, but why buy Intel and just overclock it a little? Something like an Arctic Cooling Freezer 7 Pro won't require you to remove the motherboard to fit it (unclip the fan from the heatsink or you'll have a nightmare fitting it

and it will be quieter and run cooler.

I think the comment about the idiot bit was self-deprecation and a comment on your good taste. I think. Both items mentioned are first class equipment, and certainly no cause for embarassment.
