[Atal]

I got my E8400 Batch# Q809A170 I will post results maybe next week, I still have to get a PS for my system, its going to be watercooled!

[hmetro24]

hi guys whihc is the best e8400 ?? thx
which batch pm plz thx

[zfactor]

Q816A on the way to me... will post hopefully next week some results

wow q816... can i ask where you bought it from?? that must be a really new one

[dropglock]

Did anyone get any any degration with the E8400's? I have owned mine for 2 months now and when I stress test my e8400 with OCCT It didn't crash. Now it even crashes on stock speeds and crashes on clocked speeds too. Can anyone help me? What should I do.

Anyone seen any results on this stepping q803a706 haven't seen one posting of it yet. geez did I get the only one made on that day right now running 4333mhz with 1.37 volts

I think it is your ram my friend. Occt will crash right away if ram timings or voltage is off...

Ok thanks. I'll see what happens when I borrow my friends ram and test his.

Finally got my E8400 , Q807A179 lets hope it doesnt have much trouble overclocking past 4ghz

[Garrett]

Hmm I'm not sure what to do... search for a 814 which seems to clock like hell... or stick with my Xeon E3110 (4.2 @ 1.33v)... tempting

[ANP !!!]

How are the Q745A783 I am getting one from my friend.

[Leeghoofd]

3 new E8400 CPU's arrived today : 2 batch Q816A044 and one Q805A546

Currently testing (going straight 3.6ghz, need to quickly test here, if it passes at or below 1.1, I will try 4ghz) one of the two 816's... current result 3.6ghz stable at 1.22Vcore under load, going lower than this I get stuck on the post screen of windows, not a good sign

Bios 0812 on the PK5 DLX, Vcore is set at 1.2750, no LLC -- drops to 1.24 in windows and further to 1.22 under prime small FFT's... will post a screenie as it passes 30 minutes, then I will try the 805 ( got a good feeling with that one )

To be continued...

EDIT : Second Q816A044 plus minus the same performance 3.6Ghz at 1.23volts, tried a quick bump up to 4050mhz, I need 1.36Vcore (under load)

Q805A546 seems promising, tried it at 3.6ghz could go as low as 1.1volts there.. now testing 4ghz at 1.24Vcore ( 1.3 set in bios ) temps are pretty high small FFT's 60°C on real temp...cooled with a dual rad....

[zfactor]

wow so the 805 is under water at 60c???? man these new ones seem worse and worse..

[Leeghoofd]

K my test watercooling setup are my old things I still had laying around : Dlaing pump, Swiftech Apogee block, Extreme Flow 240, Yate Loon fans ans 8/10mm tubing

Piccie here :



I'm putting some sort of Excell sheet together from the known results here, just stable 24/7 speed, Vcore, batch and mobo and cooling used

Grab the XLS file here :

Only at post 540 guys , plz ahng in there lol

[ANP !!!]

Nice Q805, I got a chance to get it and the Q745, but seeing your high temps, I am glad I choose Q745.

[zfactor]

ive looked and dont see anything in the 7xx's around.. ill have to check ebay maybe.. im only running air so im not sure ill do even anything over 4 with the 805 then.. sucks..

[Leeghoofd]

K I did the full list published here in one Excell file (though I took the ones that had some proof and no suicide shots)

Have fun with it, will be easier for some to find a good or crappy batch... though there's some big luck involved

got my 8400 running 450x9 with only 1,24 under water prime'd also at 4,6 with 1,45 but too much heat

[X2beach]

what is the Max Vcore on the E8400 on Waterchilled Setup ? Mine takes 1.47 to get stable at 4050 Full load temps are 40C

Plz post full batch, a screenshot of a stability test and ya hardware specs so I can add you to the list...

This is my Q745A567



I LOVE my chip

You shouldn't go above 1.4 really, 1.45 is the total max for a 24/7 setup. Many people won't go above Intel's specified max which I believe is 1.362 (or at least very close to that).

And by the way, welcome to the league of crappy CPUs, what batch do you have?

q808a256

[LordEC911]

Just snagged a retail E8400 for $141.
Batch# is Q810A055.
Wafer is 6A1356, pretty sucky according to Hipro.
Will toss it under a TRUE w/ some MX2 hopefully this weekend.
