**Official e8400/e8500 Retail OC Thread

[Rickpatbrown]

Look what I got today- I was wery suprised I havent expected E0

Looks promising. I'll be all over these bad boys if they can hit clocks/volts like that consistently. I can't bring myself to buy a quad core being that no program I use will ever use the extra cores. Where are these chips coming from, Germany?

I brought my E8400 down to 3.915Ghz. I will keep it at 1.55v and see if it continues to degrade. It is 15+ hours Orthos stable.

One thing that makes me wonder is that I ran Intel Burn Test the other week. My chip went up to 77 degrees. I can't rule out wether that had something to do with the degradation that I experienced.

At the moment I'm at 4350mhz at 1.344-1.35V Stable

[RCG_Bex]

Haha I lol at your V's. Mine gets 4ghz @ 1.19v and it's rated 1.25v when it ran stock

very nice, where did you purchase it?

[Furiøùs]

Are these E0 Stepping E8400 available in US?
Pretty confusing. My E8400 has progressively gotten worse. used to need 1.36v at 4.01Ghz and now it needs 1.38 for 3.91.

Pissed is not the word!

Was 1.36v at 4.01Ghz your initial overclock. These chips seem to clock higher when you first get them, but need a little more juice after a week or so. It should be stable from here on out. Let us know if it continues to require more voltage.

You shouldn't experience any noticeable effects from running 1.36volts for some time.

got a source for that?

It was, but that 4.01Ghz number now wants 1.425v under load to be stable. thats not a ''little'' more juice by any means unfortunately.

Probably going to pickup a E8400 E0 stepping next month once newegg gets rid of their C0 stock.

They have over 40 of them in stock

a big sigh mate, do not compare E8600 with E8400 totally ridicilous

By the way my E8400 does 8 x 500 at 1.21Vcore stable so the difference is big in price yet low on Vcore...

[DjLeco]

What's your real opinion about it?
FPO Q807A367

[anzial]

How do you tell E0 stepping from C0 one? I've got brand-new E8500, pack date 8/7/08, Q822 batch. And why exactly E0 batch better than C0?

[gurusan]

Does the S-spec number on the side say SLAPK or SLB9K? SLB9K is the E0 stepping....

[anzial]

SLB9K, so I guess it is E0 stepping... Now I need to a pick a mobo to oc this baby with I've got some decent DDR2 memory, any suggestions on what mobo to use with this? I'm coming off 975 chipset, nice one but old

Asus p5q - no vdroop. That'll be my next board.

E0 steppings: They'll be easily recognisable by the new sSpec numbers: SLB9J for E8400, SLB9K for E8500 and SLB9C for E3110.

nice, where'd you buy it?

[anzial]

nice, where'd you buy it?

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?

[breakfromyou]

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

[anzial]

Weird thing, the E0 e8500 hangs on boot with this Fry's crappy ECS mobo but the C0 e8400 works just fine... is the cpu dead? or just not supported by the motherboard?

EDIT: NM, bios didn't support E0s out of the box. I've updated the bios, so it's all good now So it's warning to those who are buying new E0 stepping cpus along with new mobos - mobos may not support them out of the box ECS came out with new bios only a month ago, maybe others did it much earlier than that...

hi
here is another sucker for you guys E8400 Q818A254.this one not even go to 4Ghz stayable with OCCT no matter what volts i put in.i also used auto
in bios but no go. in windows it freezes and reboots.as you guys konws 9*445 setting is very easy for MB and RAM to handle.any body else with this batch and p5k dlx MB whats your experience.i know most of these suckers make you very frustrated when you overclock them.

Hey which Fry's? Fountain Valley?

LagunaX, quit chasing me around, lol I've answered your question in e8600 thread

[cincyrob]

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.
