A rare 'is my overclock safe' thread :-P

Ello, I thought these e8400 were able to hit 3.6ghz (400fsb) on stock volts, so I aimed for that last night with little bumps on voltages and whatnot, and hit that magic figure on my asus p5e x38 with these numbers:

VCORE: 1.25625v
CPU PLL: 1.66v
FSB: 1.26v
Northbridge: 1.31v
Southbridge (I think it was called that): 1.15v

So yer, that all looking good, and if so and based on this info, what should I be looking at to get to that wonderful 4ghz figure?

Not totally sure you want to be putting 1.66v via CPU PPL voltage. Usually 1.6v is the max for 45nm CPU's.

There's no need to increase PLL until you start encountering stability issues after maxing your vcore. Leave all the voltages alone apart fro CPU Vcore, you can safely raise that upto 1.35 with no problems so you still have plenty of headroom there.

If you are getting 3.6 with 1.25 I would be surprised if you couldn't get 4ghz with 1.3, maybe a nudge higher.

See its little things like this that make me smile, I shall have a quick go now (and put the PPL back to 1.6, cheers Ozzie)
