Most consistent, highest overclocking SINGLE core A64?

I'm really liking the idea of a Opteron 148@250FSB running 1:1 on my DDR500 mem@ 3.0ghz...

3.0ghz too much to ask for? And on what voltage?
Cooler is a Arctic Cooling Freezer 64 (heat pipes)
 
Opteron 148 @ 250 HTT = 11x250 = 2.75 Ghz not 3 Ghz

Best single core for getting there is (DUH) FX57 or a high end Opteron model like 146/148, preferably a handpicked stepping.
 
oops thought the 148 had a 12x multi for a sec so the math was off.

but will the FX57 OC higher consistently than the 148.. or not?
Its not really a "duh" when you give two answers!
 
I would have to say FX57. This along with the FX55 is the preferred single core over at xtremesystems, and they get some pretty crazy overclocks.

As for what single core 64s acheive the highest percentage overclocks on air then I would have to say the lower clocked s939 opterons - couldn't say which exactly though.
 
why would you want a high priced single core when the cheaper dual cores clock just as high? If you wanna hit 2.8-2.9GHz, you should be able to find a pre-tested opty 170 here on the forums or ebay for under $500, maybe closer to $400.
 
Realistically the San Diego cores over clock extremely well and quite consitantly with a much smaller budget. With a bit of effort and the right board 2.8-2.9 is quite likely. I have a 3700+ running 2980 with 1.55v or 2905 with 1.47 and with the xp-120 I peak at 52C and idle around 38C, what more can you ask for with a price around $220?
