4.65G i7 920 - EX58-UD5P on LN2

Last night i try to play my i7 920 with Gigabyte EX58-UD5P on LN2 and well it can make impressive results on my i7 920 to WR now!(maybe) :D

System Setup....

i7 920(ES)@~4.65GHz, Temperature control about -25C to -30C all benching
ZK rev2.1 ln2 pot :p:
GIGABYTE EX58-UD5P, F1b bios
G.SKILL 12800C7-2GBHZ/12800C9-2GBNQ
ASUS 4870X2 TOP CFX
Western Raptor 150
Silverstone OP1000W
Vista SP1

Setup Pic.... :D

Results...

Max bclk&CPU freq. - 4657MHz (221x21) temps ~ -25 ํC

Pifast@4.65GHz

Wprime@219bclk(4.6GHz) - for Wprime it sure for running under 4.38GHz from real multiplier coz cpu have load over 2xthread

PCMark05@217bclk(4.51GHz) and for pcmark too it'll run under 4.3GHz on benching time :)

some action under CPU load for Turbo mode with CPU freq.

Some 3DBenching@~4.5GHz, for 2k3 and 2k5 i setting CPU affinity to only CPU0/CPU1 it'll running on 21x multi if don't setting multiplier will drop back to 20x on benching time :)

Very impressive results with 920 there. :up:
But I thought the multiplier would not drop back to 20 if the cpu was cooled well - even running multithreaded (from what I read)?!

Nice Job ! ZolKoRn. It's Monster 920. :shocked::up:

nice rezults;)
y didn't u use your c02 cascade?

I've already asked before, can you tell me what thermometer is this?

Nice job there :up:

looks this board loves i7 920, good job, bro:D

Amazing abang Paizol !!!

Very nice ZoLKoRn

no , 920 with high Bclk seems to dont like too low temp. Under cascade it s very hard to oc it :(

Thank you to all :up:

I'm not sure to all... but after i'm alot of tried with Spi if i running one or two thread multiplier not drooped but if three thread multiplier will drop to 20x, May be turbo mode can work on 100% load only two-core if over two-core it'll back to normal mode :)

What you mean ? if brand name it's CIE 307P :)

Yah i think that too look like it don't like low temps coz from i tried it not different between -30C and -50C and maybe not stable on low temps but if on idle load my chip it fine to about -15C :)

my both 920 works fine not bclk overclocked under -100° but one time oc , i need to reduce temp to arround -40°

thx for posting good work

Thomas, that is also a good explanation, when you are looking at 965xe high clocks, bclk is not high but temp is low, considered to -40

nice to see everytime your bench sesion Paziol.......keep pushing !!

I m running 965xe + 4.9ghz @ -105° without issues.

great job ZoLKoRn :) how about the bclk clocking on just air with this setup?

Huge oc on the low end chip :up:

ya and what bclk?

Crazy numbers on a not so extreme chip bro!! :D

did you have to bypass Overspeed Protection in the BIOS?

very nice that setFSB works with core i7 :D

Very nice results. November is going to be an expensive month for me

Really good work!

What kind of voltages did you give ZoLKoRn?
Bios shots?

Impressive clock, well done, mate :UP:

Quiet well done yeah ! Now let's see what's about a i7 940 would be able to ;)

excellent job zolkorn and Gigabyte

221 is as good as it will ever get unless intel shows mercy and gives us lower QPI dividers it seems form saaya's thread heh
