**Official e8400/e8500 Retail OC Thread

[Bullet92]

Guys, I said at the page before that E8600's coming in August (10th) and the price will be 200$. E0 stepping is on every pre-relase Intel CPU and it's always better then retail one's.

[Chri$ch]

in germany is the retail E8600 available and its a great clocker

this is with watercooling (water @ ~34°C+)

[zfactor]

wow i may be buying another chip after all...

[unclewebb]

Here's a review of the E8600 and they get some nice clocks out of it.

They also mention the E8400 - E0 coming out so once the present inventory is gone we'll probably start seeing them at an even better price point than the E8600.

[cincyrob]

so then the E0 is the better of the 2 then??? im gonna have to really consider the E8600... 4.2ghz 24/7 everday im likeing... still at low volts.

will the E0 version of the E8400 have the higher multi as the E8600? 10x multi...thats nice.

[zlojack]

If the E0 E8400 clocks anything like the early results I'm seeing from the E8600, then getting a nice 4.2 GHz on low volts shouldn't be a problem.

I'll probably give them a pass, since I've got 4.2GHz on 1.36v and I'm pretty happy with my chip.

Still... the E8600 at 10X is pretty sweet.

[cincyrob]

to get 4.0ghz for me i need 1.3625v max to get it stable. i don t wanna run it that high justfor 4.0ghz. i think i might be able to use 1.350v but not sure if it would be stable. but i think my mobo and mem might have something to do with it.

[cincyrob]

ok i see i can get the E8600 here in the US now. but its nothing like what everyone is saying. its only 2.5ghz and L2 cache is only 3mb... here is a link to it???wth is this??
http://www.newegg.com/Product/Produc...82E16819111009

whats a socket P does this require a new mobo..

guessi should have asked this in the E8600 thread....

Processors Type : Mobile

[gurusan]

erm thats a mobile P8600

[cincyrob]

DUH!!!!!!!!!!!!! heres my sign.... sorry for the ignorance there i just got excited seeing E8600 here in the states..lol

dang a lappy with that power..lol

E8400 Q815A092

[cincyrob]

does the DDR3 mem help out in th OCing anymore than ddr2 800/1066?i know you can get higher freq with them but does it actually help the CPU being DDR3?

sorry to ask so many off the wall questions, but thisis my veryfirst build and im still learning what will do what...

[AriciU]

Indeed, a friend and I just got e8500s from 2 different suppliers, both Q814As with 1.225vid. We were lookin at your crazy VID and being very jealous.


And I cant find a link to Coretemp .99, only .99.1...can you post it on rapidshare or something?.

Here you go. http://rapidshare.de/files/40107029/...9beta.rar.html

LOL, never crossed my mind to click them.

Nice CPU you got there.

Indeed it is. Thanks I'm wondering what the E8600's will be able to do Prime/OCCT stable for 24/7 on air.

Does anybody knows something more about OC-ing E8400 from Q817? Some people said, that can't reach 4 GHz on acceptable Vcore, but no one shows screens. I can' believe that this week is so terrible.

Mine was awfull. It needed 1.42v for 3960Mhz. Nothing more then that was possible with my cooling.

same here had 2 of em and both needed more than 1.3650 to do 3.8

[zfactor]

hmm mine is a e8500 q817 im at 4.2 with only 1.328volts i know its not a e8400 but i heard the same about the e8500 as the e8400 you have so im not sure but mine im sure could go higher yet

what other settings do you have??

[cincyrob]

i have my mem set to +.04v
mch +.01v
?+.01v
mem set to manual at 4-4-4-12
not much more to set with this mobo

[zfactor]

ahh yeah sorry i didnt look at your sig. ill bet with more setting you prob could tweak it more. isnt there some secret pages in that bios or am i thinking of a different mobo??

[HamTard]

E8400 Q815A077 on stock vcore (CPU-Z says it bounces between 1.184 and 1.200, can't make change stick due to F4 BIOS glitch on EP35-DS3L) at 9x370 (3.33GHz) seems good so far on small FFT p95

DDR2-800 running at 740 to stay 1:1, PCI-e locked to 100MHz, C1E and EIST disabled, stock cooler with fan on max and 60*C Prime95 according to RealTemp 2.60

I'll try 375 later, the first time I tried it I had my RAM at 900MHz at the same time and one core failed prime95 (large FFT, max heat test with some RAM) in about 5 minutes, but it could've been the RAM that was unstable.


Ambient is around 30*C

Here you go. http://rapidshare.de/files/40107029/...9beta.rar.html

Thanks. That version of coretemp shows my VID as 1.1125V. So which is correct?

Anyway I just completed 8 hours of orthos:

[Pisklink]

I'm very busy trying to overclock my new system. And I have to admit I had a pretty hard time on getting some decent overclock. I just read this page and saw some complains about the Q817 batch. Well, I guess I'm unlucky then cause my CPU has batch number Q817A240 (pack date 4-6-2008) with a VID of 1.25V (in Everest).

I have the following results at this moment which seem te be stable. However I have to admit that I'm still trying to find some better settings and need to finetune. I would like you to shed some light on my current settings and maybe give some advise which would be much appreciated.

CPU: 4Ghz (9x445 @ 1.43725V) (RealTemp, Idle: 40 & 36; Load: 54 & 50)
RAM: 1780 @ 1.94V (8-8-8-26-2T; specs are 7-6-6-24-1T)
NB: 1.54V
VTT: 1.3V
DRAM static read control: disabled
DRAM dynamic write control: disabled
CPU spread spectrum: disabled
PCIE spread spectrum: disabled
Load line calibration: performance (this setting seems to prevent much of Vdroop according to CPU-z)
All other settings are on auto

In my opinion the Vcore and NB are bit high. Moreover I'm not sure what the highest acceptable values are for these settings. Anybody has some guidelines? But when I compare my settings with other E8400 owners I get owned big time although my settings need some finetuning. Is this only due to a bad CPU batch? Any help would be nice.

Intels rated max for the E8400 is 1.3625v so anything over that they say may degrade the lifespan of the cpu. With all the reports of degradation around, I'd stay under that.

Lower the vNB and keep retesting to see what happens, all boards are different.

Thanks for your fast reply. I don't know how serious these degradation reports are but if the temps are alright I don't really mind setting a higher voltage. Considering the life span of a CPU would be 10 years or so and with higher voltage it at least still have a life span of 3 years. Of course I would like it to be as low as possible, so I will fine tune and try your advise but 1.36 is a no-go I'm affraid when aiming at 4Ghz with mine CPU. And after reading the E8600 article I'm thinking of buying one by the end of this year.

Lowering the vNB won't work I think because actually the opposite worked out for me. By taking the vNB higher I could get these CPU and RAM clocks.
