PSL 920 @ 3.89GHz 1.375V stable on AIR

[liebremx]

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.

wow, that's nice.

can you run some dual superpi 1M and 32M?

 

[koolzb]

Yes... we want to see how much Superpi scored.

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.

 

[jlbenedict]

Sweet!

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.

 

[Faikius]

Nice overclock

 

[anandtechrocks]

Very nice glad to finally see something nice from Intel...

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
---------------------------------------
1M: 34.297s 34.157s
32M: 41m 56.891s 41m 56.578s

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.
