**Official e8400/e8500 Retail OC Thread

[derektm]

Anybody got a E8400 from Newegg ($199 ) yet? If so how are they clocking and what is the batch #, pack date, etc.

Mine from Newegg comes in tomorrow but I was wondering the same. Did you get one from Newegg?

[Xvys]

Okay I've given up and am going to either try another cpu or motherboard.

P5N-E SLI won't run stable @ 450*9 with ample amounts of voltage to the northbridge and cpu.

Could just be mine or could be because no official bios yet. ?

Edit:: Should've done this before...going to check stability at default settings of 3GHz, with default voltage and 1333MHz FSB. See if it's the board and bios.

Try 445 x 9, Shampoo. My old E8400 wouldn't boot into Windows at 450FSB with 1.55v, but at 445 it was happy as a clam at lower voltage. I have the exaxt same batch Q740 12/20/07 packdate as you. I took my old one back today as I had bad core readings and this new one is about bang on. I have just booted into Windows at 450 x 9, but it is not stable. Not sure any other week would be any better without superior cooling.

Say $224.99 at NewEgg, I was thinking about ordering one...

Shampoo: It has always been a struggle to get boards with the Nvidia chipset to reliably run at 450 MHz and beyond.

BlueAqua: Thanks for showing us what these new 45nm processors are capable of with adequate core voltage. Very nice.

Yeah getting mine Thursday. How much did you pay, I talked to a online rep and got $25 off, so I payed $199.99 shipped

[adamsleath]

are their enuf 4x00's for oc database yet?

[CanadianTSi]

Anyone else notice that all 8400's seem to have a VID of 1.125v and 8500's are 1.050

Mine - Batch Code # Q746A381
S-Spec - SLAPL
Pack Date - 1:04:08

1.27 volts - 9 x 450 = stable. game and prime tested for about 2 hours so far.

1.4 - 4.3 ghz stable for short periods of time.

1.5 stable for 4.5 ghz for short periods of time.

havent messed with the voltages and max OC much yet.

highest FSB so far, 565.
lots of testing still to go.
just giving my results.

i have the same exact batch code and pack date. mine does 450 x 9 @ 1.275v. low volts for 4ghz, but once you cross that threshold, the voltage requirements jump dramatically. for 475 x 9 i need 1.375v. 500 x 9 needs more than 1.45v as i cant boot into windows with those settings.

[Kryckter]

I have one from NewEgg.

Batch # Q745A356
Pack Date - 12/27/07

I can get 450 x 9 with 1.35 vCore. (1.375 in Bios)

Anymore than that and it crashes, no matter the vCore, But I am pretty sure that is my memory holding it back. I have 4 gig (2 x 2gig) G.Skill 1006. It is at 900 mhz. Anymore than 950 mhz on the memory and the system crashes constantly. This is on a P5K Deluxe Board.

How's that work ?

[Shampoo]

Well I've decided to give back the cpu to my boss and use it in a client's system.

I'm gonna wait on this. My system just isn't stable at default settings either, so bios update is awaiting.

As for this batch? I don't know, but it looks like a lot of people are having to pump a lot of voltage into their E8400s to get above 4GHz or even 4GHz stable.

I will wait on this.

Cheers,
Mike

i dont even know how you use excel, sorry an admin can do it

I got three E8400 retail CPUs to 590fsb on warm air (Summer in my land) with Asus P5B Deluxe Rev 1.04G. That's 590fsb dual 32M Superpi stable.

Results here, but something very odd occurred too.

P5B Deluxe owners, don't throw your board away yet. Test it with 45mm

[lefy]

is there really that much performance variance from different batches at this point? where do you buy these that they let you inspect the box prior? seems like ordering online is just not worth it if there's that much oc success relying on the batch

[X.T.R.E.M.E_ICE]

Ok here is my first test with my new E8400 C2D Q746A474
VID: 1.100v

Asus P5K-E
8400 3.6GHz 1.08v
PNY 8800GTS 512
2GB Crucial Balistix 9600
Crappy cooler using Liquis pro

your just expecting too much.

4.5 ghz on air, isnt gonna be stable, or easy. even with these.

sure, it can be done. mine can do almost 4.8 on air so far.
but not much is stable past 4.2-4.3ish.
atleast, not to the point where I am willing to push more Vcore into these.

I am still learning the ins and outs of my CPU here.
it OC's insanely, but getting stable is the hard part so far.
these are very jittery little processors.
alittle voltage off, and you will be unstable. yet they boot at almost any speed you set them at.

E8400
Batch# Q745A357
Pack Date 01/04/08

my P5W mobo feels so dated now. i actually traded a P5B-D for this because i was more interested in CrossFire performance than a high FSB.

since my BIOS sucks, i'm stuck at 1.225 Vcore for now. i was able to hit 425 FSB (3.825), which is my motherboard's limit. i have no idea what my new CPU is capable of. time to start saving for an X38.

Dave could you please give some more info about your 748A cpu regarding clocks-volts required (4ghz and up)? I need to choose between 2 of them...
thanks

[turtleonviagra]

How's that work ?

I tried to price match their price to onsale's.com and they did. So they just took $25 off the price

[GOESA]

Guys, I need some help, I have got a E8400 Q744a - i have problems getting 4ghz stable on gigabyte P35-ds3 even at 1,425v it failed, but I have a suspecion that my mobo undervolts alot, I set 1,425v in bios an CPU-z and HWmonitior show the vcore at 1.36-1.376v .

some one got any special setting they have to disable to get it clocking better? I see people getting 4ghz at 1.3v in bios.

Did I get a dud?`

/Grau

[bonzo_catalin]

That makes about as much sense as an ashtray on a motorbike.

I don't think i understand .

on water plus an apogee gt on top

It is air , as i said before .

Disable EIST in bios, so it won't revert back to multi 6 when idle in windows.
Nice chip

I know that , i kept C1E enable to cool down much faster . I forget , Q740A480T. Next time on Dimas SS

[CERO]

E8400 with PFO# Q748A102 will arrive here tomorrow, I can recall I didnt saw any results from this week. Hope it is a good clocker, will keep posting

[=[PULSAR]=]

On air plus an VantecTornado on top

how stable was that?

[K404]

Please can I ask a favour of some E85/E84 owners....

Please can someone run a few 3DM06 runs at xxxMHz and xxx+200MHz and report back the CPU scores, id like to see the scores and scaling.

Thanks! First person to help gets a pack of cookies of the flavour of their choice

[Dosagex]

when does the E8500 release in the states?
