Back to old days...(Overclocking Celeron 2GHz Northwood s478)

I want to overclock my Celeron 2GHz Northwood s478.
I also have A Data DDR 400 1GB ram 1 stick working on 266MHz with AOPen MX4B motherboard. I saw that my mobo doesn't supports voltage changes, but w/o increasing voltage how far i can go? Any advice?

For more you can check my "systems" on my account.

I once took an Asus P4533 (Stock HP board) with a 2.0ghz Celeron to 150fsb with SetFSB (3.0Ghz) and benched it. Soon after it locked up, but It worked for a few minutes, lol.
That same CPU in an Abit VT7 with the vcore maxed as high as I could go only pulled about a 125 fsb before it wouldn't boot anymore.

I would say 2.5ghz with a pretty decent voltage. With a voltmod and something like 1.65ish vcore, I would say 2.7ghz might be doable.
On the stock vcore, I think around the 2.3ghz range would be about it.

If you are going to do that, I'd get some more quality RAM. I overclocked an old P4 on a S478 A-Open motherboard and it killed the RAM. And I hardly overclocked it...It was a 2.8GHz P4 and I only had it at 3.06GHz. I was folding on it, and it kept blue screening until it wouldn't boot cause the cheap RAM in it died. Of course, the kingston lived. I would guess on stock volts you could get it to 2.2GHz? I know you're doing it for fun but those old Northy Celeron's sucked tongue.gif 128KB L2 cache....man, that thing would be slow at 20GHz laugher.gif
