bad VID for e8400? - Page 7

post #61 of 75
I'd just keep bumping it up 20 FSB at a time. Look to post/windows. Run a quick CoreTemp. Low FFT's on Orthos for 2 mins to see your high temps. Go back. Raise the FSB. No post/window? Add vcore. Back and forth. Till you hit 1.3625 vcore. And whatever is stable at that point is what you have. Mine was 4.01GHz.

Now if you can hit 4.1, 4.2 with a lower vcore. Great. But I doubt it. Not with the Q81's

Chances are the other programs are wrong.

If RealTemp is wrong, then the fixed CoreTemp, DFI's BIOSes, EVGA/NVIDIA BIOSes, and the info Intel gave them on VID are all wrong.

If you checked your VID (on a 45nm chip) with a version of CoreTemp that you downloaded more than 10 days ago, it was detected as too low.

Yeah. I usually go alot higher than 20 FSB.

I usually go 3.4, 3.6, 3.8, 4.0, etc, none of this 20FSB stuff lol.

So far I've got 1.225v -- my VID (1.220v idle) and (1.192v with vdroop on load) stable for 40 mins at 3.6GHz

I'm going to try to see how far I can go on stock volts even though the vdroop is technically undervolting it.

I must say, I'm very happy I bought the e8400.

Yes. It's an EXCELLENT CPU. To save time you can just run Orthos for 2 mins small FFT's and check your temps. I run OCCT for 10 mins. If it passes. I go higher. Saves a lot of time on getting to your max overclock

lol Too bad it's my girlfriend's cpu

I just want to be very thorough as far as voltage and overclock goes. I will try to get as high as I can with stock volts, and then move up.

It looks to be stable now at about an hour in 3.6 GHz @ 1.225v (1.192v with vdroop).

EDIT:

I mean, this goes to show why 45nm and e8400 is single-handedly the best CPU's I've ever owned.

I mean, it's trumped my Q6600's overclock already and it's only at 52C and 1.192v..

that's just incredible. Great value.

Yes. It's a GREAT chip. But what's the use in having a Corvette if you can't take it out and see how fast she goes? hmmm?

thawny's girlfriend: Let him take it out and race it a little ok? He'll thank you and love you forever if you do

hahah, you bet! Sickest chip ever.

I would choose this over my Q6600 @ 3.6 anyday.

UPDATE: I'm in windows at 3.8 at 1.275v bios (1.248v idle / 1.24v load)

quite a big jump from 3.6 at 1.225 (stock volts).

What do you guys think? good? avg?

edit: it's loading at 58C at 3.8 GHz. Loaded at 52C at 3.6 Ghz.

That's about right for a #Q80 or #Q81 batch. The vcore will be exponential after that.
That's exactly my results also. If she's not going to fold or needs massive CPU power I'd just keep it at 3.6GHz@52C myself. Good luck!

thanks man!

I'm at 4.05 GHz atm, using 1.31v bios that will most likely lock up.
