FYI, Jet123...
I also am running a Barton 2500 on an ASUS A7N8X del. mb,
it overclocks nicely w/o any problems.
I currently have mine set at 2.1GHz and 400, that's right 400, FSB.
You have to set the multiplier to 10.5 from it's original value of 11, but it runs smooooooooth like this and cool...44 C. Just make sure you have adequate cooling in your case. Funny thing is on boot, it's now recognized as an Athlon 3000. I installed an XP3000 and couldn'tget that piece of crap to run at it's minimum specs. ( 2.1 GHz) no matter what I did.
