652MHz+ FSB on P965 Commando

[tiborrr]

http://shrani.si/files/eastkoastl13ab2.jpg
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

Thank you for reading! :up:

Kind regards from Slovenia,

no words ......


:shocked:

[Solarfall]

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

[TheKarmakazi]

VERY nice! :clap: :up: 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 :up:

[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 ! :yepp:
Sky-high FSB for that one, really great ! :up:

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

[eva2000]

woah crazy stuff! Commando still giving FSB love ! :D

[TheGanG]

Excellent, i like that old mobo...

[Viss]

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

[Nanok]

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

[Chruschef]

incredible:shocked:

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 :eek: How did you mount it? Did you use coppershim? Nice fsb for old P965 anyway :up:

[Hyperhorn]

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

[Moonman]

Thanks again. :)


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

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

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 :D
Can take the picture of mounting if you like.

Commando :up:

[tiborrr]

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 :up:

[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!

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

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

[headman800]

awesome work guys! :up:

[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. :up:

[Spacemaster]

Great work neighbors :up:

[tiborrr]

Thanks Spacemaster ;)

[Nordling]

why use PCI-E VGA?

[Oliver]

awesome work man, that board is still screaming, congrats

keep oldschooling it

[tiborrr]

@Nordling:
No gain between in FSB PCI & PCI-e cards, really. It's not the NB's PCI-express controller that's under stress here or causing instability at high FSB. Besides, it's in 2nd slot at PCIe x1 so only using one PCIe channel (other one is probably used for SATA ICH9R controller).

@Oliver:
Thanks, we'll keep on oldschooling it! :)

[Oliver]

sounds awesome

will have an eye on you guys

[Reefa_Madness]

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

If your offer of taking pics of the naked NB pot mounting (and the pot) still stands, it would sure be appreciated.

I'm trying to make one and it would be very helpful to start off with one already proven to work.

Besides, you can see the mounting plate in the first post of this thread:

Greets,

[Reefa_Madness]

Thanks for the pics.

BTW, PM being sent to you with a question about the mounting plate.

[MarcusFoX]

thats ruff that p965 must be suckin hot.... at that frequency

[makaka]

P965 Commando is one of the best LGA 775 motherboard , nice result

[ceemic]

Good old Commando :)
Congrats on that excellent result :up:

I got my first Commando few weeks ago.
Today got a little time to do a quick air-testing:

http://valid.canardpc.com/show_oc.php?id=470173
Still much to do and I'll put it under LN2 also (CPU+NB).
Hope to compete with You guys :)

[F.O.G.N.A.]

Wow........impressive work guys ;)

[tiborrr]

Thanks guys :) This Commando was sold a few weeks ago, waiting on arrival of a new Commando which i bought on eBay :up:

[Pcuser]

Impresive work, Commando still strong.
Maybe yr next board could do 700:D
Or you can get a 659fsb (http://valid.canardpc.com/show_oc.php?id=417366) Dfi like mine;)

[Nanok]

I was the lucky buyer of this nice board.
max fsb with dice on nb 654
max spi 1m stabel 646
max spi 1m with multiX10 635
I have high hopes for this cpu, look at the low vcore

Very nice results mate!
Do you think you can gain some MHz with higher Vcore and ln2 on chipset?
Will we see sub 7s from you soon? :up:

Next bench we will try, asus evo with dice on NB, last time the evo did 625 with air on nb with multiX10
Soo i hope and cross my fingers for sub 7
