Old Fella humm! That will be me then.
Barton xp2500
256 DDR400 Crucial ram
Gigabyte ga-7vaxp ultra
Nvida fx 5200 128meg
coolmaster aero 7
Chieftec dx case (Window side)
loads of cold cathods and leds
40meg + 80 meg 7200 Maxtors

Ive heard the gigabyte isnt too good for overclocking? So I might give it to my son and get a new mobo also read that the duron 1.6 is an excelent cpu for overclocking, at £30 you havent lost much if you F**k it up eh? maybe that would be a good starting point on a new mobo.Thoughts?
Cheers

That board is ok for o/c but isnt up to todays standards - it should allow DDR400 and cpu FSb of 333Mhz, but it uses KT400 chipset which doesnt OFFICIALLY support that speed. I doubt you'll get 350Mhz cpu FSB with but you might.
The latest Nforce2 boards are the king for o/c if you want extreme speed - cpu FSB of about 480Mhz is apparently achieveable with the right board

The new Duron (1.6Ghz) is a bit of a beast for overclocking, though the XP2500 Barton is also superb - the barton o/c to about XP3200 levels, whereas the Duron is almost capable of XP2800 speeds (and thats without a following wind or downhill stretch)
Not bad for a £30 slug of silicon

Thanx Marky
interesting stuff. I think what I might do is grab a 1.6 Duron at the weekend pop it in the giga and have a go. Its all a bit scary the first time (a bit like s*x prob) if it all goes ok which it prob wont ,but I learn like that, I will get a new mobo and try it with the Xp2500 then hand the giga down to my son. I actualy sound as if I know what i'm on about scary stuff this. But very rewarding

A few bits of advice -

Find out what the max voltage a duron can take (think it might be 1.85V, but not sure). You'll need to up it to get more stability.

Increase FSB by 5 or so Mhz at a time and check stability. Apparently long term gradual increases are best as it allows the chip to 'burn in' (Sounds ominous!!)

Lock you AGP/PCI bus or use board dividers

Find out where the Clear CMOS jumper is on your board - you'll amost certainly need it when you push too far and it doesnt boot
