oc'ing a barton

[avi85]

I was wondering which prime95 stress test is the best for stress testing a barton.

I was also wondering how far to back down after finding a stable speed. with athlon 64's I usually back down 2 MHz (off the bus speed) just to cover fluctuations over time I was wondering what people do (did?) for bartons.

Any other AthlonXP overclocking tips would be appreciated. Thanks.

xp OCing is pretty straight foreward. I just used the mixed test most of the time. the tests tell you what they are testing, so just choose one based on what you are changing.

I built a few overclock Barton XP2500 systems. Most do 2.2GHz (200x11) easily, assuming you have PC3200 ram and a good heatsink and give it a little more voltage.

The system I'm posting on right now is a 3year old XP2500 Barton. 🙂 Been running this way since day one. I have a SLK900 heatsink and a quiet 92mm fan. Idles at 40C, stress usually 50-51C. Stable as a rock. I had to up the voltage on mine to 1.7 (on day one) to get it stable at this speed, but it's been at this speed since then. 3 years. 😀

as a matter of fact I am using a 2500+ my ram is ddr333 but it is perfectly stable at 398 (199*2) which is my max (cheap board, no ram dividers, overvolting etc... just an fsb up to 199)so far it has been priming at 194 for 8 hours so that would give me 2134MHz on a very crappy mobo, I guess I got lucky, although 2200-2300 would be nicer but not worth the premium on the mobo.

I just went down this road recently... and I'm still trying to squeeze some more MHz out of my 2500+ Mobile barton.

I was able to get to 2340 or so and remain stable. Anything over that, and the BIOS reverts to 6x100MHz at startup. I typically go down 2MHz from my highest overclock, like you. Best I could do was 213x11 and it's been priming on & off and folding for the last few days at 211x11. I typically use Prime95's second torture test (highest heat, power) unless I think that my RAM is on the ragged edge, then I use custom w/700MB. I'm running an Asus A7N8X Deluxe rev. 2.0

You're lucky, unlocked multipliers, adjustable voltage, a dream...
