652MHz+ FSB on P965 Commando

[tiborrr]

EastKoast Of OC-Lab2 a.k.a. Moonman & tiborrr pushed their Commando P965 board to the FSB limit yesterday night. The result, 652MHz FSB, looks to be one of the highest P965 overclocks ever achieved and which we are very proud of. The NB didn't show any signs of coldbug even at -175°C, it practically doesn't have coldbug at all, but lower than -150°C didn't yield any FSB gain.

System:
Intel Core 2 Duo E8600 Q822Axxx
ASUS Commando P965
1x1GB Crucial Ballistix Tracer PC6400 (D9GMH)
GeForce 6600GT 128MB PCIe
Hitachi Deskstar 160GB SATA
BeQuiet 700W PSU

CPU cooling: sharp's cascade @ -103°C
NB cooling: LN2 + D.I.Y. tube @ ~ -150°C

sharp's cascade | CPU + NB cooling | the platform | -130°C and going... | Good contact on NB pot


Validation @ 652.03MHz - http://valid.x86-secret.com/show_oc.php?id=452862




Thank you for reading!

Kind regards from Slovenia,

excellent numbers...im curious what sort of voltages did you guys use for the NB ??

[TheKarmakazi]

VERY nice! Did you run any pi?

[Bullet92]

Nice to see the "old" king of FSB in action again. Give us some benches with this awesome FSB speed

[Moonman]

Thx guys.

excellent numbers...im curious what sort of voltages did you guys use for the NB ??

1.625 V in set in bios. Didn't like more or less.

[CryptiK]

Wow, really impressive result guys! Good to see old school P965 in action again.

[George_o/c]

It's so nice, seeing that old filthy board on action !
Sky-high FSB for that one, really great !

Keep up the good work guys, always nice to hear from Slovenia

[eva2000]

woah crazy stuff! Commando still giving FSB love !

[TheGanG]

Excellent, i like that old mobo...

[Viss]

Impresive. Always good to see Commando results, great boards.

Old love never dies !!!
What was det max fsb without extreme cooling on nb ?

[Chruschef]

incredible

You mean that anywhere below -150*C didn't yield any performance gain? To get the northbridge to clock that high stable, it required below -150*C?

[bartx]

NB pot is really huge How did you mount it? Did you use coppershim? Nice fsb for old P965 anyway

[Hyperhorn]

Great achievement!
If there's a legendary S775-board out there, it's called "Commando" for sure.

[Moonman]

Thanks again.

For screen, max fsb with HR-05 was 640 MHz, same with water cooling.

incredible

Under -100°C yielded no performance gain, we just wanted to see how much cold it can take.

It's made from E6600 stock cooler
Can take the picture of mounting if you like.

Thanks guys, really it's a pleasure to work with Commando board even if it has a zillion BIOS glitches. In comparison with some P45 boards (Biostar :/) this is heaven

[mAlkAv!An]

Those results are really impressive, espacially with such low voltage - seems to be all about temperature.

No max. FSB for SPi1M though?


btw: the cut off heatpipe cooling looks nice too

[Nanok]

Could not resist, my 4th Commando should ONLY be my 24/7 system, no overclocking.
Incredible stability spi 1m 630 could run again, and again!





And max fsb with dice on northbridge



Still great preformence, from this old lady 3544 X 12.687 = performance 44962.728

[WaterFlex]

Good old king Commando...
Great job, well done, bro

[headman800]

awesome work guys!

[jesperme]

sick commando board!

[tiborrr]

Great job Nanok. Well, this was our second Commando board, first one stopped at about 595MHz FSB on aircooling while this one did about 630-635MHz. I guess the cryogenic temperatures really helped gain us those ~ 18-23MHz.

This motherboard is now up for sale, if anyone interested PM me, i can ship internationally.

Great work neighbors

[tiborrr]

Thanks Spacemaster
