After fiddling around in the BIOS, my Athlon 64 X2 3800+ Manchester is exceeding my expectations!
Stock is 2GHz @ 1.35V
I have run Sandra for 12 hours now at 2.6GHz and 1.2V, rock stable. Maximum temp. reached is 44C with CPU fan @ 1000 RPM.
I recently upgraded from a Barton 3200+, so my overclocking and temp expectations were somewhat low. My brother wants to build a new computer, and if these figures can be duplicated, there is no sense in him spending the money for an X2 4600+.

Wow! /blink.gif" style="vertical-align:middle" emoid=":blink:" border="0" alt="blink.gif" /> Your CPU fan is at 1,000RPM and pullin' out 44C? Whoa, that's quite impressive, what fan/heatsink you have and what's your room's ambient temperature?

Here's hoping they can be. Only the minority of cores can OC to their "max", the rest will probably get smacked in the face at around, let's say, 2.45GHz. I guess this depends, but you're right on the ball...why the heck pay more, when you can breach the barrier between a x2 3200+ and a x2 4600+ with 1 day of work?

That clock is not generally common on that chip, especially at only 1.2V. The problem with getting another and hoping you will get the same results is that CPUs are like people, they are all different. You can get the exact same CPU (same core, model, etc..) and one can OC really well, like yours, and the other can not OC any at all. You could probably get 2.3-2.4ghz on "most" of the X2 3800s but you can't buy one and expect it for the above reason. I am all about OCing but you can't have high expectations going into it because you will either be disappointed because it didn't meet your expectations or you will be greatly surprised, like you are, and get a really nice OC. The X2 3800 in my opinion is worth it but if you want easier OCing you might look at an Opteron 165. Its the same as the X2 3800 but has better thermal properties which generally lets it OC higher than the normal X2s.

BTW, nice OC.

Right now I am using the stock AMD heatsink, lapped with AS5, and a Panaflo fan. The Panaflo puts out great cfm with low noise and low RPM. Ambient temp is 23C, and my case temp (Antec P180) hovers around 27C. Temps are much higher at stock voltage. I have a Thermalright SI-120 in an unopened box somewhere, but with the temps I am getting now, I might just ebay it.

Thanks!
Is there any real benefit to the skt 940 opty's, or would he (my brother) be better off with a 939 opty? Besides the registered memory, of course...
The price diff. seems to be about $60 between the two formats.
