Hi guys. Well its done I've spent 2 days tinkering and got my system as good as it will go, though I find its not as well as I thought it could. I've managed to push an xp2600 b from 2083mhz to 2140mhz at 1.675v. My board has gone from 166mhz to 171 mhz with a multiple of 12.5. Its my RAM that seems to give me grief, maybe thats why I've peaked so early. I have a 1g stick of seitec that was sold as PC3200 but I've been ripped its only PC2700. Whenever I try to manually input timings or manually adjust its ratio the system crashes. As long as its on 'high performance auto' settings its fine. I ran prime95 for 12 hours with no errors and at 45c. I also ran memtest86's 9 tests with no errors. Is it because the RAMs max clock is 166 that I cant do much more? And is an Aopen that I've now discovered is only 250w sufficient? Oh and thanks for such a consise overclocking guide, this site rules!

1GB memory modules have never overclocked really that well to begin with, and PC2700 is a pretty big limitation. It would best to get 2x512MB PC3200 or higher if the board supports 200FSB+. 250watts is really really low, 300-350 is the understood minimum these days, but I'd recommend at least 400.

yeah, the ram is probly your problem. also, 250w is NOT enough. u should get a new one, perferbly over 400w
dang it yiffy, u beat me

glad everyone could help with the overclock, yes, PC2700 will be limiting you, as it'll only go up to a certain mhz rating, then crap out on you. you can go higher, you'll need better RAM though. i have 2700, and i need new sticks, although i got my 2.8 to 3.3

Cheers for the quick replys. OK consider the PSU gone, 400w coming up, any brand recommendations? Checking the boards specs, it supports up to PC3200 and the max FSB in BIOS is 200mhz. It also says it supports ddr 200/266/333/400 so I'm guessing those specs are a x2 multiple of the RAMs actual clock speed, is that correct? So in short what I'm asking is can I go much further if I get 2x 512Mb PC3200?

Good brands are like Antec, OCZ Power Streme, PC Power and Cooling, Tagan, and Enermax for PSUs. DDR means double data rate, so yes it's two times the actual bus speed. If the max FSB is BIOS is 200 then there's no point in getting anything higher than PC3200 since PC3200's clock rate is 200MHz (DDR400).

Just gonna note out if anyone was going to buy a 'Tagan' the company is E-Power, I thought I was just stupid when I searched, guess not.
