Unofficial Wolfdale E8400/E8500 OC Reports

[Zenoth]

Alright, looks good so far...

11 Hours and 43 Minutes at Small FFT's, I hope it holds on there forever, I'm sick of raising the vCore and other voltages for a mere 700Mhz over-clock.

Nice Zenoth

Testing some X48 from asus , this P5E3 pemium is expensive but just for "asus xpress gate" I love it !

and rocks too .

560 fsb air .

bios settings remind me ROG mobos !

I think mine has been "degraded" a little.

It was stable at 1.216v, now I'm priming at 1.23v. I know what has caused it, the last few days i have been benching it, mostly around 1.475v. A couple times a 1.55v. Maybe it won't degrade anymore

 

[Dragon Heart]

still testing max fsb air

568 x 6

and some DDR3 12800 ( 1600 mhz )@1860 2.08v

Going for an hour now at 4411...as usual I have a high VID, but as usual I've got pretty high clocks. Air with Tuniq Tower and eVGA 790i, a week 805.

I dunno how accurate the temp is supposed to be, can anyone comment? It's spiked to 83C on a couple of occasions.

 

[Hazaro]

You are testing 4.4Ghz stability @ 1.544V, on AIR!?

WHAT IN GODS NAME DO YOU TH-

Oh it's Gautam

That VID is pretty high though

 

[El<(')>Maxi]

These things run hot, at least compared to what coretemp reports on 65nm. They're even high when monitoring with Realtemp. My 3350 idles around 52° on H2O @ 3.6GHz, loaded around 67°, all on default vcore

Insane air clocks Gautam .. How are you finding your 790i board?

Love the ocability, hate the quirkiness.

I have to admit, the changes to the cpu and NB ref voltage have helped my clocks so far. I was struggling to get more than 11 min stable (prime95) at 4.05MHZ..I have the voltage at 1.39v actual and still no go. However, I changed the cpu ref to .63 and the NB to .67 and have been going for a couple of hours now..there may just be something to this theory after all

Of course, I think that my clocks are still not right, but that is another thread

I'm 21hrs ORTHOS stable with specs in my sig, will post final OC and SS when I'm done

How many hrs stable is it at this point?

 

[OldSkool]

I'm at work, the final testing phase begins in T minus 2 hours. I refuse to stress while I'm not home as I'm the only member of the household who knows anything about computers. I figure I'll start tonight when I get home and if it's stable overnight, I'll let it go for the 8 hours I'm at work(biting my nails the whole time) and post results after work. I figure that should be a total of 18 hours 30 minutes by that time.

I dunno how accurate the temp is supposed to be, can anyone comment? It's spiked to 83C on a couple of occasions.

first off, as others have said...

1.54v, what are you thinking... oh, okay, we've been down that road

Props for having the cojones to push to 1.54v to achieve 4.5GHz though!

As for your temps, its been my impression that the TJMax for these chips is actually 95C, not the 105C that CoreTemp uses. Since these programs calculate your "actual" temp as just a function of how far you are from the TJMax, CoreTemp gives you 10C higher than it probably is. That said, you can subtract 10C from your Coretemp, or just use Realtemp, which has the 95C adjusted TJMax for the 45nm chips.

Also, its been my understanding that one should absolutely never hit or go over 20C under TJMax. Since its 95C for these chips, and your adjusted spike puts you at 73C, you might want to lower your VID; if not for temp damage, then for electromigration. Have a heart and love your E8X00... stop the torture now!

PS - You're crazy!!! I'm afraid to go over 1.4v, and thats been with temps no higher than 65C!
