Just wondering if anyone's messed with OCing their AMD chip and if so what's the chip rated at and how far have you had it going.

More specifically, I'm looking for someone that has OC'ed their 2900+ or 3200+ 400 FSB CPU's and to what extent but curious as to any other speeds out there.

I'm running a 2800+ 333 fsb running at 3100+ (2287.1 core clock) with a FSB of 183 (from 166) but I'm wondering how much cap space is left with the 3200+'s since it's at the end of the line for the barton core. Were you able to get it up to 3300+, or 3400+ or is there just no space left for it to be stable past the 3200+ mark?

Well, I have one Barton-M, and the upper limit is 2.4Ghz on a ABIT NF7S with a modded BIOS. I keep it on 2.3Ghz with a FSB 230Mhz, DDR 460 8) I also use Athlon XP Tbred 1700+@ 2Ghz (2400+) in the other computer on Abit KT7-A. The highest rated Barton CPU in my country was not an "-M" version, but a standard 2500+ desktop Barton. It went to 2.9Ghz (for screenshot, or watercooled), and 2.7 Ghz for "everyday use".

Anyway, the difference in speed between 2.4 and 2.3Ghz is negligible, so the difference in voltage and temperature make the further OC of the CPU fruitless. But, the difference in FSB is seen; you could try to OC your FSB to at least 200Mhz, or more (depending on your mainboard). That should give you some more juice out of an oldie (but still powerfull) barton

Oh one more thing: Mobile Barton is not that much better overclocker then regular, but it's 100% unlocked. That's what it makes a better choice, not the "lower power consum"-thing. See if your Barton is unlocked. If it is, lower the multiplier to 11.5x and FSB to 200Mhz. That's the "basic" configuration. If you use old DDR333 memory then increase the voltage of the memory to 2.8/2.9V and then OC FSB to 200Mhz.

If your barton is locked, then you're going to have to do a little "wire mod" that can be found on www.ocinside.de

I could also give more detailed info If you but inform us about your motherboard/RAM

P.S. Top 10 in my country, select "AMD" and then "barton":

Thanks guys for the reply. I was more or less curious, but I like all the info.

I'm running this on a Gigabyte GA-7VAX board. I love the board, seems to run real stable at were I've gotten my 2800+ chip to. The board doesn't officially support 400MHz FSB, but at 183 it seems to run pretty d*mn good. Also running two 512 Micron MX2 DDR 3200 Duel channel memory sticks in the thing (although the board doesn't support duel channel).

I think your right about hitting the max FSB because I can't go any higher other wise it's way unstable.

Next question for you then, if I were to put the 2800+ into a board that could handle a 3200+ chip (meaning that will use a 400MHz FSB), I should be able to push the 2800+ chip a little higher and get a faster core clock speed then the 3200+ which should actually be faster then the 3200+ with both the core speed and FSB towards the max (400mhz) then correct?
