Overclock AXP 3000+

[TheBruce]

I have an Athlon XP 3000+(333FSB not 400), Barton core and I was wondering how far I can overclock it on stock cooling? I've got a couple of extra fans in my comp, a total of maybe 3 lol, but i'm buying a few new ones very soon. How far do you guys think this can overclock while still being stable

bump, cmon help guys please, my X800 Pro is getting limited hardcore here

The reason that the 3000 costs more is because it's already been tested to confirm that it runs the faster speed; this is also the reason that the mobile XP CPU's are more cost-effective. From a lesser price point, they will on average perform as well as a stock 3000, if not better. But no guarantee - luck of the draw when using the XP-Mobile. It's quite likely that you can run a Barton 3000 as fast as a stock Barton 3200 has been tested to run. No guarantees, though. There may well be as many or more Barton 2800's that on average will outperform either or both of the faster-rated XP's, and the results are still a gamble.

At various times, the enthusiasts have identified particular variations of XP's that have tended to perform better than average, and thus, there has been interest in knowing exactly which batch, which week, the cpu's were produced. Not specific enough? Sorry!

Hard to say, since each cpu is different in OC abilities. Since the cpu has a locked multi, you can only raise the FSB. So go for it!

After you raise the FSB, run Prime95 etc to test for stability. Prolly no need for Memetst86 since the ram w/b performing well under it's specs (200/400 mhz).

If it fails P95, raise the vcore (voltage to cpu) by .025v (ex. If your at vcore of 1.65v, go to 1.675v) and try again.

Install Motherboard Monitor 5 on your pc and watch the temps. I don't like to go over 60c at load (temp read from socket, not diode, diode w/b higher). Try out the "sys log" feature in MBM5, it's great for recording temperature and other data while your gaming or whatever that puts a load on the cpu.

is there any way to unlock the multiplier? besides i thought it was. I can change it when i got my bios

CPU's dated after week 39 of 2003 are uber-locked (this date is part of the stepping codes printed on the cpu).

I could change the multi in my BIOS when I was using a desktop Barton, but it did nothing.

IIRC, there is a way to change the multi, but it doesn't work on nForce mobo's.

so basically i'm screwed for overclocking besides FSB? And i've heard the max they can usually go on bartons is around 180 =\

I get my AXP 3000+ up to 2420Mhz rock solid, by raising the fsb to 185 (370 DDR) and running at default voltage on my AOpen NF-2 chipset motherboard.

Don't have stock heatsing though, got a copper base heatsink with a normal 80mm.

Havent pushed it higher cause I'm happy with it as is, and 250MHz jump is queate a decent a leap on a AMD CPU anyhow.

Well, you're not screwed. But you are stuck with a fairly high multi - so you'll be limited on high you can get the FSB. My guess w/b that your OCing will likely be limited by using stock cooling. Just see how high you can get the cpu b4 it gets too hot with the vcore increases.
Good Luck with it.

I've been running mine at 400mhz FSB (XP3200) for over a year with zero problems.
