A while back Ironbits had some very serious horsepower from some overclocked 1.6G xeons.

If anyone is interested their is a new overclocker, like the xp2500 barton mobile and the ULV Xeon.

What is it? The 165 Opteron dual core. Quite interesting it may be my next purchase.

Unlike normal opterons this one is a 939-pin, yet it's a dual core with 1mb cache each. People have been overclocking these from stock voltages and frequency (1.3V? and 1800Mhz) to 1.575V and 2.8Ghz.

That looks very very impressive.

I think this might be a good upgrade for anyone with a 939 board which supports dual core. For 300-400 dollars WOW. Wonder how a pair of these would do in sieve/factor.

Anyone have one direct experience, yesterday I stated that I was totally happy with my dual barton 2.4G box. Now I'm uncertain.
