i7 920 @ 5404.4 mhz

Hi guys,

after a few dry ice runs i finally started to get the hang of the classified for a bit. bought a 920 D0 for a contest, but due to the high humidity and hot weather in holland i didnt really got the chance to properly do it.

Today the weather was a bit better, and insulation aswell.
Main goal was basicly just seeing how hard it would go,
QPI slow mode, single channel, and just fiddling with all the voltages and pci-e bus.

At the end condensation finally got me, so unfortunately didnt really did alot of benching, but highest i did ( few days ago ) was 5175 32M, and 5250 mhz superpi 1M.

Specs:

EVGA classified E760
Dominator GT 1866 CL7
Intel i7 920 D0 ( batch 3912B351 )
Corsair HX1000W
XP SP2

realise im like 0.4 mhz under the WR, but above 257 mobo started doing weird, mouse was jumping across the screen, it was fairly stable ( 258 ) but the validations always bugged out? :(

like this:

http://valid.canardpc.com/show_oc.php?id=678505

:rofl: :rofl: , and when i went to the cpu tab it still said 257 bclock, so really odd :down: els i think i could have gotten that 1 mhz more on the bclock.

But this is the final ( submitted ) result , really happy with it :yepp:

thats it for now, hope to play with something with a bit more multipliers next time :up:

the same here.....when I increase bclk with e-leet it is always 1 bclk less....the same happens with set-fsb!:mad:
One more problem is that if you set XXX,5 bclk it will change to XXX,0. For example set 205,5, then open the cpu tab(cpu-z or e-leet it's the same) it is 205:down:

Keep it up:)

That Classified, what can I say, it's a miraculous board ! :yepp:
Nice processors as well mate, keep pushing it :up:

Thanks, wasnt even that. im aware that like all classifieds have, for instance you select 1 mhz, it becomes .4 mhz . but if i select 258 the cpu tab showed the same mhz as if i selected 257 mhz. so was just to buggy above that i guess :)

Thanks all for kind words!

Great job those d0 "b' batches seem to be a great overclocker. Keep up the great work.

Huh... 257MHz Bclk it really nice ! and one greats job from EVGA with Classified it amazing :up:

Nice clock!

Was that on air or water? hehe

Congrats :) Try next time to save multiple validations (they may vary about 0.5-0.8mhz depends on clock generator) so maybe you'll be able to beat WR :D

@[200] , the run was done on dry ice :)

@ Bobbylite,

some settings:

Vcore 1.512 ( bios )
VTT +350 mV ( so thats 1.55 )
CPU PLL 1.8
IOH PLL 1.5
QPI PLL 1.15
IOH Vcore 1.25
IOH/ICH I/O 1.5
ICH Vcore 1.050

Single channel,
Qpi slow mode

And 122 pci-e :)

@bartx yeah, but i was so confident i could get 258.4 validated, i really focused on that alot.
but that damn bclock kept jumping around :P , and then after like 4/5 hours i got some condensation troubles. and about multiple tries, from what i can see is that all the classified owners have it somewhat similair, like enter in 1 bclock get -> 0.37. so if i got that aswell, i still would be 2nd, because Hondacity submitted it first.

And thanks all for kind words, perhaps it'll go under LN2 one day, but i think im going to start looking around for a W3540,
and let someone els have fun with this cpu. :)

Way to go!
Get more dice and you might go higher the next time! :D

Very nice results

waiting for results on LN2 ( 6.0 GHZ ? Bclk 285 ? ):up:

Keep pushing it :clap:

Very nice result :up: these cpus have big potential of OCing only mobos are :down:

I had the same problem aswell, just much earlier. BCLK 242, fine. BCLK 243, mulitplier started jumping, and bclk started jumping.

Sick score there! think we will see more from you.

On LN2, and perhaps gunning for the WR.:yepp:

That's some great frequency, especially for dice!
But what about the Pi32m scores?

wow, impressive bclock! :toast:
try booting at 19x cpu multi and see if that helps
did you try a 22x cpu multi run?

Huh , 22x multi? isnt -> less cores -> higher possible multi a i5 thing? :P

And thursday ill get some dry ice for a last time before it's sold, 1M / Pi_fast and hopefully some 32M.

and obviously ill post results here!

ajaidev

Is this possible??????????????

http://valid.canardpc.com/show_oc.php?id=685868

Intel Core i7 920
Freq : 7169.61 MHz (247.23 * 29)

I dont think soooo!! I remembered the name kurumi he's from japan and the last WR i heard he had was around 56xx ghz
09-04-2009, 01:43 PM
thijs

more looks like his 975 got reconised as a 920 or so? :P which then had a huge bclock jump and he validated that? :P sort of my 5,5 ghz validation lol

Anyhow, some results. my 32M effiency is bullocks, i know, havent used maxmem or any other tweaks yet, still trying to figure everything out. consider it a test :P

anyhow, started off with 1M. fiddled around alot, basicly went with 2:10 mem multiplier, actually didnt test 2:8 and tight timings, perhaps that would've bin better?

http://www.hwbot.org/result.do?resultId=893563

next up i tried some 32M, as i said, this is really the first time trying 32M, let alone knowing how to tweak it, so my eff must be horrible :rofl:

http://www.hwbot.org/result.do?resultId=893567

Last but not least, pi_fast , suprised it actually ran that high, guess that says it was really the bclock limit , whilst the cpu had plenty of room left.

http://www.hwbot.org/result.do?resultId=893564

All in all i really enjoyed the cpu, great potential, next up is a W3540 or 950 :)

try getting W3560 instead of w3540:rolleyes: same price

Impressive BCLK there man!
My 920 D0 stops at 242 for now, but of course i will push it more :D

What the max you can get with 4 cores / 8 threads 3d stable?
09-27-2009, 07:45 PM
lesstutrey

great results, however belated they are. Train yourself for superpi before your next dice session. Low-Clock it and get max performance so you know what to do. You'll be able to kick some but if you can get your clock efficiency up a bit.

thanks, yeah i know. im fairly new to it all. did 1M / 32M / Pi_fast all in a few hours, time for doing timings / sub-timings wasnt really there.

the 920 is sold a few weeks ago, just looking for something good now so i can start benching again :up:

Since 1366 the 'NB' is now on the cpu chip ;)

thanks guys, waiting for my F1 LN2 cooler, dewar from germany, and still trying to find a nice cpu.
after that the Liquid nitrogen will come around asap, so i can start benching again.

Going to see if i can get a gpu on aswell, i can still learn alot from 2D, especially tweaking the memory, and 32M.
But 3dmark06 is so cool :)

Can't wait to see some LN2 results from you. Just find a nice chip as this i7 920 was and make some nice numbers.
That i7 920 was awesome :up:
