**Official e8400/e8500 Retail OC Thread

[gundamit]

Did little more testing with the e8400 Q809A161 on Swiftech H2O-220 Compact Kit. Just some 3-D fun on an old 680i mobo with 8800GTX SLI @4.6ghz:



Even managed 4.7ghz run with some old 7900GTOs.



Then the mobo started getting squirrely ... didn't start behaving again until I re-flashed the bios ...

Hi all. Haven't seen many of q805's in this thread. Guess i'm rather late here with mine but it's hard to get a recent batch in Russia
Full batch is Q805A160. I've had 2 of those with exact same batches, the first one was a bit weaker overclock-wise. Did 4.15 GHz with 1.4 set in bios (1.384 by cpu-z & Everest). But I didn't make any screenshots of it (I knew the second one would be better). The better one does 4.2 at the same voltage:

I know that 1 hour isn't considered very stable here but for me it's enough.
The second sensor always shows about 10C lower temp than first, it's calibrated on the screenshot.
Motherboard is P5K (vanilla) and cooling a lapped BigTyphoon VX.

Hi guys ive just managed to get stable @ 4Ghz but i need 1.39v. Is that classed as high or not ??
My batch no is Q748A402.
Cheers Paul.

Picked this up a few weeks ago, finally did some testing.

I have some tests with my E8500, but still expecting 5,1+ GHz

TheGanG> 3Dmark06 scores? Nice overclock on the Gx2!!!

[Hughyhunter]

That bios is stressful!!!

Pretty average CPU Paul, really nothing special... good ones get 4ghz below 1.3Vcore, golden ones at around 1.2 Vcore

That bios is stressful!!!

Typical Gigabyte bios mate

OC list updated, plz do not forget to mention batch and hardware involved when posting new results...

What is it i need to view .xls, excel?

[Leeghoofd]

yeppo... done on office 2003, hope it's compatible for everyone

[XxPuNTeRxX]

Hey, Here is mine!!

I know its not an awesome result but I'll be playing with it and see what it'll be doing in the near future. That orthos is still running

I'm pretty sure this is as far as she'll go. I cant get anything higher to run stable. I tried 4.2ghz at 1.4 It'll boot woindoze but wont run orthos past 10s.



4GHz!!

I just wanted to let you guys know that I released an updated version of RealTemp last night.
Here's how it looks running Prime on a Q6600.



A temperature difference between the two dual cores within a Quad is normal.

A lot of improvements and new features have been added in the last month.

I was forced to write RealTemp because none of the available programs at the time could accurately tell me the core temperature or VID of my E8400.

Here's the kind of testing that went into RealTemp:
http://www.xtremesystems.org/forums/...&postcount=573

You can read the documentation, including how to calibrate it to your processor here:
http://www.techpowerup.com/realtemp/docs.php

And if all this sounds good then download the latest version:
http://www.techpowerup.com/downloads...Temp_2.60.html

Edit: The new Gamer Mode flickers and is a work in progress. Let me know if this would be a good feature to perfect in a future version. I'll try to get this right using RivaTuner next time.

[Vatos_locos]

unclewebb about real temp to me it sais that both sensors movement is 8 what do i set for calibration ? i just can't understand the instructions

[unclewebb]

Vatos_locos: If sensor movement is 8 for both cores then at least you know your sensors are working properly.

To calibrate, you need to run your processor as cool as possible and compare the temperature RealTemp reports to your room or water temperature. On an E8400 at 6 x 333 MHz ~ 2000 MHz and with the core voltage at aboout 1.10 volts, the reported idle temperature should be about 5C above your room or water temperature. Use calibration adjustments so both of your cores or all 4 of your cores are reading the same thing at idle during this test.

Open your case up and turn your CPU fan to its highest setting if you are air cooled.

This method of calibration will improve the accuracy of your reported temperatures from idle to approximately 60C.

thank you very much ill try when we tern the A/C @ cold because we have 35*C ambient temp here in Greece

Just ran occt for the hell of it on my e8400 but I was a little confused by the 5V and 12V test results at the end. Shouldnt both the rails be as close to solid as possible ? Psu is a st1000.

[Flasker]

I would think it's a bug, can't see it running like that. Measure the voltage with a DMM to be sure

[Vatos_locos]

with 1Volt @ 5volts rail you pc cannot even boot up not mentioning the hard drives the spin up with 12V but again with 1Volt you should not be able to recognize them even inside the bios :p so this is far away from try results

Hello,

I am new to the forum (and overclocking). Just wanted to know if this CPU is a good overclocker. q807a067

Planning to use it on a rampage and thermalright 120

Just google q807a067
You can expect about 4.1ghz @ around 1.3v
Not too bad imho
Good luck torturing it

If it's an E8500 Garret he can expect that, no idea of the type of CPU

Q807A367

Result added to the list

Hi all : This my first post in XTREM forum , i've found an E8400 Q807A269 from a store in belgium , it's not too bad but i'snt not the best .

4000MHZ@1.18v and 4400MHZ@1.34v all in Aircooler

Yeah, 4.4ghz on air occt stable isn't that great...whateva!

Have you tried prime95 or orthos blend stability?
