Retail E8600 Overclock, Temps, Settings Thread

Sub 9 on water!

Awesome Chri$ch!

I just picked up an E8400 EO from Microcenter in Minneapolis. I walked in and they were just putting them on the shelves. I'll see how it differs to the E8600.

Hi folks. I'm planning to replace my Q6600 for an E8600. I'll continue to use my lapped TR Ultra 120 Extreme on it so I'd like to know what range of clocks I can expect from it. 4.3~4.5GHz?

[Brahmzy]

I've got a lapped TRUE and I'm getting 4.40 with fairly low volts/heat. Unless you get a stellar chip, don't expect more than that on air. Most of us have found the jump to 4.5 from 4.4 is a big one and not worth the heat/volts.
Hopefully you'll get a killer chip though!

[dinos22]

nice chip chris

i'm liking this Q820A599 E8600 i tested tonight

E8600@ 4800MHz

vcore was jumping between 1.44v and 1.42v

Air cooled >> TTBigTyphoon

[Chri$ch]

yeah, its my best chip... but it dont like voltages above 1,60v (only 0,01v more and i cant boot into windows)

best 1M time i get



i test later max clock for 32M

[USFORCES]

Where did you get it? First Q814 Ive seen.

OOPS, its a Q820A306

[Geebs]

Not that hard to lap.
Flat surface (glass, clipboard, etc.) and $4 combo sandpaper pack at autoparts store (400/600/800 grit - some say finer grit 800 up to 2000).
Up and down (not circular) 10 times, rotate 90 deg, 10 times, etc. until you turned 4 times with 400.
Repeat with 600. Then 800.
You don't need a shiny surface - just a flat one without big scratches (hence 800).
Also, you don't need to get down to all copper either (though it is nice for a better thermal gradient) - just a flat surface.
This will void your warranty though (as does overclocking lol...)

Thanks a mil for the links and advice. I did as was suggested, lapped, washer, and still my temp idle at 40c

Grrr... checked ihs with a razor, as well as thr TRUE, which is indeed bowed out a bit in the middle, but nothing drastic, AS5 has good spead, I dunno what gives... Ohhh it just dropped to 39c

That is why i switched from AS5 to MX-2. MX-2 is more like AS Ceramique - more putty like. With uneven surfaces it fills in the gaps for better contact. AS5 is quite thin and won't cover uneven spots as well. Unfortunately the middle is where the cores are. With my washer mod TRUE and lapped 8600es I idle at 29/30ish and under orthos load max out at 55c @ 4.3ghz 1.35v. Note that both cores have identical temps - good contact, huh?

What gives is that these processors and heatsinks are all stamped out in Chinese sweatshops where no one is concerned about quality control, much less their lives. Intel and Thermalright only want your money, or as they say in Hong Kong,: "Time Is Money"

I understand that businesses are in it to make money. But I am thinking that the ihs on my new cpu is not seated properly on the cores or something... I haven't has this problem with any of the 2 other C2Duos I have used in this rig...

This is really annoying me. I have already sold my old cpu, and I'm pretty sure the egg won't advance me a replacement.

FPO#: Q820A600
VID: 1.2500v

Bad luck... Again.

SuperPi 1M: 9.234s
cooling: h2o
mobo: Abit IP35

[jaredpace]

I averaged everyones screenshots and got this:

AVG: 4464mhz, 1.336 Vcore

This equals about:
4500mhz 1.36v
4400mhz 1.32v
4300mhz 1.29v
4200mhz 1.25v
4100mhz 1.22v
4000mhz 1.19v

it's obvious 4000mhz may take less than 1.19, and 4500mhz may take more than 1.36.

thx jaredpace for the effort

gonna keep my E8400 for shure

[BeastNotro]

Where best place in Canada thats getting good steppings?

I want one, but may not be able to get one for a few weeks . damn it.

Will there still be good chips out then?

[doompc]

sorry wrong thread

[anzial]

doompc, me thinks this a wrong thread to post e8400 overclocks at

[BeastNotro]

Ok i did it i ordered a E8600 and me hopes it to my house next week.

Are all of then E0 revision.

[doompc]

Sorry, I couldn't find a E8400 E0 specific. Since all E8600 are E0s...

Nice overclock. Excellent. Seems just like my e0 8500. PM Leeghoofd to put it on his list too.

Got 5Ghz running pretty stable,

i think you will find that on average for every 100MHz CPU increase you will need 0.05v

I averaged everyones screenshots and got this:

AVG: 4464mhz, 1.336 Vcore

This equals about:
4500mhz 1.36v
4400mhz 1.32v
4300mhz 1.29v
4200mhz 1.25v
4100mhz 1.22v
4000mhz 1.19v

it's obvious 4000mhz may take less than 1.19, and 4500mhz may take more than 1.36.

This German eBay guy says he's got 2 Q822A435's left in stock. I bought one yesterday & it cost me 16 euros for S&H to Holland via DHL..

The auction does state that he only ships to Germany, so you'll have to ask if he'll ship to your country & for how much..

(I'd also ask what FPO's those 2 are to be sure).

What's the safety level on these chips again? Just got 4.8ghz out of mine with 1.48v (I think it'll go lower though)

~Bex

[BeastNotro]

I thought 1.40v is safe, but soem are saying lower then that on AIR = 1.38...
