Essentially, I think this chip can go higher. I'm a lucky one and I have an unlocked Barton (hence the 2.4ghz with a 200mhz FSB and a 12X multiplier). I never modded this chip so... just luck. It?s one of the first Bartons. Anyway, it is currently running at 1.75v and stock is 1.65v. My CPU temps (I have a probe under the chip) are between 38-40c (got to love Zalman).

Do you think I can get more out of this chip with more volts (2.0? and get 2.5-2.6ghz?).

Has anyone gotten a Barton to these levels (2.5/2.6ghz) safely and still day-to-day usable? (it has to run w/out crashing, not just post)

I had an unlocked barton 3000+ 200MHz FSB. It was doiing 2.35GHz at 1.75V, I ran for a year or so at 2.5GHz on 2.03V with temps getting into the low 70s on load. I know that maybe a little high for some but it's still going now at stock.

Most chips will run happily at quite high temperatures, so that is not a major concern. I would avoid taking the voltage too high, I would suggest that you increment it slowly until doing so yields no more performance gains and then back it off a notch.
I know it's a different chip but I had a prescott running at 93C on load stable a couple of years ago.

I'm 2.5 Ghz stable all-day with my Barton XP-M 2400+.

You'll need around 1.80v-1.825v to the core if you already need 1.75v for 2.4 gHz. You might get 2.6gHz with VERY high (1.95v-2.0v) voltage. That's crazy hot though with air-cooling though.

If your cooling is good enough, you can run 12.5 x 12x for 24/7/365.

Just to show some old-time Barton power with the newest Super-Pi

This is from a 35 watt Barton 2400+ at 200 x 12.5

If you can push your RAM higher you will get more performance even if the clock speed doesnt just significantly. My Barton XP-M at 12.5*200 was fast, but 11*220 was flying. that is technically a drop in speed, but the 10% FSB increase really helped. My RAM couldnt go higher (not sure if it was the RAM or the board, or a combination of the two) but that was still plenty fast. With a Thermalright Cooler i never broke 50C load. at 1.8v

Thanks for the replies all. I'm going to try a few different things (12.5 x 200, 1.8-ish volts and see if it's stable, then a 11.5 x220 and compare). The only issue I've notice is my Mcafee Virus scan seems to crash randomly (still 2.4 @ 1.75)

have you been running Prime95 after each adjustment to make sure it is stable?

Run Prime for 12+ hours, if it doesnt error out and crash, you are set
