Yeah I know I'm pushing my luck, but I want to aim for it if it's possible just because I'm having too much fun.
Already at 4.37 stable, but I want mooooooooooooreeeeeeeee.

I also realise there are easier ways to increase performance, I just find this interesting.

So questions,

- I need a 527FSB, DDR2 and stable voltage (hoping I don't need over 1.8) - motherboard recommendations?
- cooling - will a CPU dedicated 240x140mm radiator setup keep it alive? (twin 140mm fans)
- is it even possible or are over 4.8Ghz setups purely benchmark only?
- how long would it live for? Anything over 6 months and I'll be happy.

Highest so far is 4.5 @ 1.52 volts, 99.9% stable, but not quite. I thought it was fine, Prime95 didn't find anything but games would crash out occasionally. If something goes wrong, I wont blame any members here. I realise there is no guarantees.

Edit: just wanted to add I live in a fairly cool climate, PC wont be exposed to any heat over around 30C.

Been there done that.

Anything over 4.8 is for benching only. Trust me you will hit a wall, and you will be like "what the hell... it worked at 20mhz below this"

I got it to 5.5 with my e8500 with some dry ice... i have a thread on it, its a good read.

I have so much fun overclocking to. You need to get into dry ice(DICE) and ln2 if you want the really high overclocks.

I managed 4.93 on air, but it wasnt stable.

Id LOVE to put the cpu that you have under ln2, any chance you live in austin?

Edit: Guess you dont live in austin "fairly cool climat"

haha no I'm in New Zealand. Bit of a trip.

ah heck about the FSB wall! Nothing I can do about that.
Guess I'll go with a better motherboard and see how far I can go on air cooling. I'd only switch to water if it let me do something crazy, like 5.

Damn thing is already heavy enough as it is! So I guess for motherboards only real thing I'm looking for is more regulators? Think the Asrock is a 4 phase setup, definately not keeping up. Set to 1.6V I get 1.54 in BIOS, 1.52 in windows, and 1.48 under load. BIOS wont let me set it any higher.

Go for the biostar T-power board or the asus rampage extreme ...THose are the best overclocking boards.

You need to get into more exotic cooling dude.

Buy yourself a SS if your into 24/7 use.

A good SS will pull -35 under load 24/7.

It was a modified Domino. 100cfm main fan and a modified 92mm rear fan for a Push/Pull config. It was also in a CM 690 case with 7 high speed 100cfm fans so it ran VERY cool. Idle's in the 40c's at 4.7Ghz


You gotta love the core 2 chips..... i will miss them for the rest of my life as an overclocker.

Such great overclockers. But they will be phased out just like the p4's
