Core i7 920 'D0' & eVGA X58 SLI LE

[Lamb]

Hey guys,

here are my results overcloking my new chip so far, seems like a good chip
SLBEJ B# 3939B100
eVGA X58 SLI LE using BIOS # S71H (latest -11/30/2009)

Pic 1 (05/01/10) : Tried to go for 4ghz yesterday with a quick benchmark (LinX) run to see if it could be stable around those voltage (1.329, varies up to 1.370 when @ 100% load) ; Yes it can, just need better cooling because temps were getting high as you can see!

Pic 2 (06/01/10) : Today I tried to see if running at lower voltage I could still get good results with 4ghz, barely, could only reduce the Vcore by 1 level in the BIOS. So I decided to try @ 3.6ghz with some super low voltage (I'm not used to <1.2V , would flucuate between 1.141 and 1.171 @ 100% load) Good results so far, may need a *little* more power to get it stable; Shows great temps, hope this will get even better with the Venomous X that'll be used with 2 San Aces 3000RPM @ 2000ish RPM, should arrive tommorow or Friday.

More updates to come!

Once you have it stable go for the big wu!!

I'd really like to do -bigadv, but the last time I used it, I had to stop it to play MW2, and when I powered it up once I was done killing peoples in 'No Russian' ( I keed I keed! ) the WU had some fatal error and I lost it when it was @ ~96% , ...Simply using -advmethods is much more...convenient? ... to me since I don't have these problems when I just close the VMware client, with more games coming for my lil PS3 and me currently playing Oblivion GOTY I could give -bigadv a chance once stable

Added some numbers to my 1st post!

Try fiddling with your CPU VTT, I suspect that it is probably holding your OC back, not your core voltage. Well, that and the Temps

[Lamb]

Double the VTT to +100mV, tho I'll wait tommorow to bench it as I want to be awake if anything goes bad ^_^

And yes the temps are a little high @ 4.0ghz , hope that Thermalright Venomous X with 2 San Aces will make a difference

[Sagath]

You can safely crank the VTT to 1.3-1.35v without issues. That would be +250/300 on your board. But VTT is fickle. Some processors like lots, others like a bit, and still others dont like any. YMMV.

Holy cow, just installed the Venomous X with the 2 uber fans and my temps at idle already dropped by ~13C :O

When I removed the H50 I've seen that the compund wasnt corretly ''placed'', it was all over the chip but was missing some in the middle...that's wierd...oh anyway, I just need to find a way to reduce the speed of the fans because it does way too much noise now ^^

[Lamb]

So far it's been stable for 3.5hours of LinX @ 3.6ghz, ~65 loops, I'll have it testing for 250 loop to make sure it's stable, should be done by tommorow morning.

The temps went down by quite a notch!

Low 70's > High 50's for 3.6ghz
Low 90's > Mid 70's for 4.0ghz

I'll keep it at 3.6ghz if stable since the voltage is ultra low (1.141, 1.176 @ 100% load)

Thermalright Venomous X @ max pressure (70lbs?) strapped with 2 San Aces @ 2000RPM (quiet! I can stand 3k daytime, not while sleeping tho ^^) good news : No need to sand the base, it's mirror finish and pretty clean!

Using IC7 as TIM using an hybrid between these 2 methods of application to make sure there's TIM everywhere;





Verrrrrry happy with the results so far, will post pics of the final results :D

*Note that I'm not on my computer while typing this, so I can't take SS*

Gointo bios undrer moitrting. click on fan speed and smart fan. You can set each fan speeds one each fan header. You may want ot look up this FrozenCPU PMW Y Splitter Cable - FrozenCPU.com

You may want to look into a fan controler. Evga rocks Eleeet will show you fan speeds fore each header.

This is what I use; http://ncix.com/products/?sku=38017&...facture=Scythe

Sadly got an error after 4h58m19s

I'll bump VTT a little.
