4.65G i7 920 - EX58-UD5P on LN2

[ZoLKoRn]

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)

System Setup....

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

Setup Pic....



Results...

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

Spi 1M/32M@4.65GHz, temps ~ -30 ํ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.
But I thought the multiplier would not drop back to 20 if the cpu was cooled well - even running multithreaded (from what I read)?!

[StrangerS]

Nice Job ! ZolKoRn. It's Monster 920.

[quintus]

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

[N3RO]

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

Nice job there

[hicookie]

looks this board loves i7 920, good job, bro

[Benny Lodewijk]

Amazing abang Paizol !!!

[Pt1t]

Very nice ZoLKoRn

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

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

[ZoLKoRn]

Thank you to all

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

Nice job there

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

Very nice ZoLKoRn

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

[Hazzan]

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

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

[Achill3uS]

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

[Charles Wirth]

Huge oc on the low end chip

ya and what bclk?

[Harshal]

Crazy numbers on a not so extreme chip bro!!

[AuDioFreaK39]

did you have to bypass Overspeed Protection in the BIOS?

[begrip]

very nice that setFSB works with core i7

[2chesapeakes]

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

[Razzz]

Really good work!

[BulldogPO]

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

[WaterFlex]

Impressive clock, well done, mate :UP:

[Eeky NoX]

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

[dinos22]

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
