I got an 0546 Opteron 170 (2*2.0 GHz, 2*1MB) from Monarch in the mail yesterday, and popped it in my DFI NF4-Ultra D (after a BIOS flash). It is cooled by an XP-90 with a (slow/quiet) Panaflo 3000 RPM fan.
I got up to 2.5 GHz on stock voltage (1.33 V), dual Prime small FFT stable all the way up. I was using a 166 memory divider, so when I bumped it up to 2.6 GHz, my Patriot 2-3-2 RAM was then running at 216 MHz, which was probably too fast for CAS2 on stock memory voltage because the computer hung up overnight while I was priming. So I dropped the divider down to 150, and upped the CPU voltage to 1.4V (just in case that was the problem), and I am currently 3 hours dual Prime stable at 2.6 GHz.
I don't remember the idle temperature, but I think it was mid-30s C. The load temp @ 2.6 GHz is 49 C, which is a little high for my taste. I might find out the limit for this processor and then either bump down to a cooler overclock or bite the bullet and buy a louder/faster fan.
I'll keep you updated. Overall, I'd say these dual-core Opterons are real gems.
