**Official e8400/e8500 Retail OC Thread

[dnottis]

hey guys. i rma'd my E8400 CO stepping for some heat issues this past Thursday. do ya think they will ship me the newer E0 stepping CPU? man that would be nice.i hear they work nicely with the GA-EP35C-DS3R 2.1revison i should get it tomorrow maybe Wednesday at the latest. i hope its as easy to get to 3.6 ghz as the C0 stepping i sent back.

They are getting rid of the C0 stock. I really think you will get what is leftover.

[cincyrob]

i kinda think the same thing, but the Intel guy did say it would be the newest batch number that i would receive. so i got a 50/50 chance it being a new E0 or just the newest batch of C0.
im waiting to contact Intel this morning to find out if they shipped it yet, and if they did what did they actually send me...crossing fingers..lol ill post back with the details

Hey, I am somewhat new to overclocking. However, I understand how it works and what settings to change and I have done a bit in the past, but nothing serious. I would still call myself a noob, do to lack of experience.

Any help would be appreciated as I am having trouble getting stable at anything other then default settings.

Computer stats:

cpu - e8500
mobo- p5e3 premium wifi@n - lots of options for overclocking
ram - ocz Reaper ddr3 12800, 1600mhz - This overclocks well i believe. 7-7-7-20
hdd - 4x250gig @ raid10
cpu cooler - ocz vindicator, works alright, could be better.
psu - corsair hx520w psu, upgrading to 620w when i go CF
Video - 4850 with accelero s1 attached will get a second one later.

All I want is a 4.1ghz oc cpu, and ram at default or higher speeds and rock solid/stable.

Whats a good starting point?

Hiredgoon just run the volts up to 1.40 volts and see what ya get in cpu speed
and then you can deside what you will settle for
( or go to the max volts that makes ya happy)

i thought 1.4v was starting to get a bit high on just air cooling?

[HDCHOPPER]

I got my E0 E8400 from micro center for $149.99...already squeezed a 9.9s 1M out of it on air.

eye eeked out 9.838 1 mil on my E8400 co stepping

Fry's, they are running special combo, e8500 + ecs mobo for $189 until tuesday (CPU alone goes for $199, lol). It's retail cpu, too It's funny, but the box and stock HSF is much smaller than e8400 package I got back in May (C0 stepping). Are these E0s supposed to run cooler, too?

thanks for the tip. picked up the combo today.

q822a553 E0!

[cincyrob]

well i talked to intel again and they havent gotten my RMA E8400, which is a good thing.lol but they said again that the CPU sent back to me would be the newest Batch#. im hopeing it is the E0 steppin. 4.0ghz with a small amount of added volts is what im after...

[anzial]

thanks for the tip. picked up the combo today.

q822a553 E0!

you are welcome

[dnottis]

Newegg have E0 yet?

[USFORCES]

Are you going to add E8600 to this list?

[LagunaX]

Who Likey?

$204 total with tax from Fry's in Fountain Valley, CA.
E8500 E0 SLB9K Q822a553
ECS G31T-M Motherboard combo deal

4.5ghz @ 1.36v gets a little toasty on air but manageable...



I think I'll run 4.4ghz (1.328v) on air 24/7 as temps are more reasonable...

[gurusan]

Just got an older stepping Q745A784 Xeon E3110 and it seems to be quite a nice clocker!

So far seems stable at 490fsb (4.41ghz) with 1.456V ...this is after about 20 minutes of overclocking...running OCCT 30 min now

Nice. I hope mine will clock just as good

[BlueAqua]

Hmm seems my Asus Commando doesn't like the EO stepping. It'll work, it just doesn't recognize the chip.

[HDCHOPPER]

BlueAqua .. have heard / read that a bios update fixes that
a few post up an ECS mobo needed it too

Yeah I never expected a bios update for the Commado, but they do have this one:

1703
2008/03/24 update
Description: Commando beta BIOS V1703
Patch Wolfdale E8300 will show CPU over voltage error.

Don't think there is any newer bios available that might help the Eo's

[cincyrob]

called INTEL again this afternoon. they still havent received my RMA yet. so thats a plus for me..

will the vid be the same with the E0 stepping? or has it increase a little..

question? with the new E0 stepping what actually makes it so much easier to OC these bad boys? im not no genious or anything like that so the answer might just blow me away...lmao

OMG, that's a nice chip, i love E0 Stepping ..u're temps are verry good, 60degres are not high...what cooler are u using?

[makaka]

How good in the Thermal sensor in Those new E0 processor mine show always 34c and above even under single stage

Do those E0 show sub zero temp ???

[ThatGuy16]

Wow, E0 is looking NICE!

And i thought my chip was good..

[cincyrob]

just talked with INTEL. theyt got my old CPU and the new one has been mailed out . so by friday i should have it up and running. they couldnt tell me which stepping i got. all they know is its the newest one they have in stock.?????so with wishfull thinking it is the E0

Read all the pages of this post, and any other posts you like, all the info you need is here. 4000-4100MHZ is easily doable on an E8500. And hang out at XSF, you will become an addict like the rest of us

[BababooeyHTJ]

Sorry, quick question. I need to reseat my heatsink. I have a tube of AC5 and MX-2. Which one should I use?
