Beautiful pair of E8400

kppanic · 16 Oct 2008 at 14:58

Yesterday I got two E8400 E0's with Asus P5Q-E and 4gigs of Corsair XMS2 6400C5, Palit 4850 Sonic, Arctic Freezer Extreme, and Antec 900 for each system.

Right off the boot, 444x9 at 1.34v hitting 4ghz, for both of them.

Really happy to see both systems hitting it the first try, both running OCCT, been 12+ hours now.

One system peaks at 55 degrees for both cores, the other at 60.

I'm just happy to see them run so well, had to post.

These wolfdales amaze me, I have just bought a E8500 which i currently have at 3.8ghz, took me 5 mins to overclock and a couple of hours to get the voltage down as low as possible. Temps reach 48C max. Could go further but I see no need for now. The Q6600 I had before that barely reached 3ghz and ran so hot it always concerned me.

E8500 is the best thing i've purchased in a long time ...

good effort! nice to see good chips hitting the 4ghz mark everytime

Clive37 · 16 Oct 2008 at 17:57

The E8400 really is a great chip, I have mine at 4ghz

Nice clock hope mine can do that when it arrives

Where did you buy them from? is there a way to tell from the box what stepping it is?

Edit: it looks like the Eo stepping is S-spec SLB9J kappanic can you confirm this?

thanks

Very nice overclocking!

Yup the SLB9J is the E0 stepping version of the E8400

Yep SLB9J is the one.

Got mine two days ago from oc.

Havent even touched the volts (showing 1.15 in cpu-z) and am up to 4ghz (445*9, WC). I expect to get this chip to near 5ghz in the coming days

Why is it amazing ? 2 years ago we had 3.6-3.8 ghz stable under air ?

I think its more a question of how easy it is to reach high speeds with these chips rather than just processing power (ghz). 5 minutes to reach 3.8 with room for an improved overclock is pretty good i think

james.miller · 17 Oct 2008 at 07:18

and the power they (dont) use while doing it

gurusan · 17 Oct 2008 at 08:47

3.8ghz is only a 26% clock...not too amazing tbh. I would shoot for 4.2ghz as that's a nice even 40%

mattup · 17 Oct 2008 at 08:52

Recently changed to an Asus Maximus 2 board and an 8400 EO cpu.
Currently at 4.2Ghz 467*9 at 1.268Volts.
I found that my EO stepping runs at lower volts than the faulty CO I had previously (duff temp sensor).
Fantastic chip.

CPUz will show what stepping the chip is.
Confirm that SLB9J is an EO as that is what my chip is.

You should be able to tweak the voltages down a little more. Especially as its an E0. Apologies if you have already done it.

My C0 will hit 4Ghz with 1.318v completely stable and temps not above 60c.

Hit the nail on the head of exactly what I was trying to get across.

Yes, kinda busy in the last few days,

I should start lowering voltages, would be nice to see what I can get since I have two identical CPUs, compete and see which one is the better one.

Pulse · 24 Oct 2008 at 09:47

Hmm maybe I was just unlucky as my C0 8400 Struggles to be stable over 3.5GHz, even that requires 1.325v. Tried everything to get it to 4GHz, computer literally says no.

Tetsu · 24 Oct 2008 at 10:00

Got 2 E8400 here as well. One of the best chips i've ever bought.

I reckon you could sell your talking computer and get a much better rig.

60% overclock here
