Ran two SP2004 instances on Small FFT for a couple of hours priority set to 3, affinity set (one instance per core) plus I played Prince of Persia 2 during that time :)
I'm not planning to leave the machine on for hours stress-testing so don't bother asking.

Here are the specifics:
Mobo: ASUS P5WD2-P
FSBxRatio: 278x14 = 3.89GHz
Voltage: 1.375V
RAM: 2x512MB Corsair DDR2 533
HS: ThermalTake Orbit II Blue
PSU: ThermalTake 430W W0070RUC
Temps:
- Processor: 53C Idle, 65C Load (ASUS PC Probe II under Windows 2k, using standard silicon grease, yeah yeah). Oddly enough, lm_sensors under Linux reports 44C Idle and 61C Load :Q
- Case: 34C Idle, 37C Load (Need to work on this)

** Except for the FSB multiplier and the Vcore, all the other settings in the BIOS Jumper Free Configuration were left as AUTO.
** Mind the PSU :) It works though hehehe
** I might get some AS5

If you want benchmarks let me know, I'll try to run them (No, I can't do the AutoGK thing done by Technonut because I don't have the movie. I have Matrix though, so I can run it with that).

Edit: Removed an extra 3 from the voltage.

Good overclock, but isn't that the same $200 motherboard everyone else uses to OC Preslers?

edit: woops, yeah. It is. Still a good overclock though.

Would be nice to see a ~$100 board for the 920D.

I've got the mATX baby brother to that board, the P5LD2-VM with a 920 @ 3.5Ghz, stock cooling and voltage. So far it's never gotten above 42C at full load. I just picked it up the other day for around $90 If I remember correctly. I killed one of my crucial 5400C4 sticks last night, so I'm at a stand still till I get another, but I think I can get it a little higher.

Hey smb3d, tell us how far you can take it... very interesting.

As for the benchmarks I'll run SuperPI tonight, hopefuly :) IIRC SuperPI mod 1M was around 35secs (two instances, affinity set), and SuperPI SSE2 (one instance) was around 31secs.

Sorry about the dead Crucial stick man. I hate it when that kind of thing happens. My old 17" CRT died on me a few nights ago about 9 years of loyal service. bleh.

3.5 ghz is pretty good, especially if it's running at acceptable temperature levels. That's a definite improvement over the 820D. I don't know if I'd take that over some other overclocking options out there, though.

*Drumroll* The results:

Dual SuperPI Mod, affinity set

Nice. I'm gonna get slaughtered for saying this on AT forums, but I'm actually considering ditching my 4800+/A8N-SLI Premium for a 950/P5N32-SLI Deluxe. I'm really pleased to see low temps. on Presler chips.
