Retail E8400 @ 4.8Ghz Sub 10s SPi 1M

Ok, second thread in two days, but you don't get these results everyday. This chip is a monster, only thing holding me back from a 5Ghz is ram. :( All settings were set in bios, no clockgening.

Testbed:
Mobo: Asus Maximus Formula (0907 bios)
CPU: Intel E8400 (Retail)
Batch #s: Q745A356
RAM: Team Xtreem PC2 6400 4-4-4-10
Cooling: TT Bigwater 745 + Apogee GT WB
OS: Windows Server 2003 SP2

CPU-Z Validation for 4.86 Ghz: http://valid.x86-secret.com/show_oc.php?id=301016

SPi 1M was run at 4.797 with ram timings of 5-6-6-21-3-42-6-3-8-3-5-4-6-4-6 2.4v

I took a screenie at 4.811 Ghz (9x534.5) but I just realized that file was corrupt when trying to upload it. Also, the first SPi 1M ran was 9.625s but system crashed while saving it.

Anyway, here goes:

if your ram is doing 630 something, and your FSB is only 533, then I would say the ram isnt holding you back.

you just need to change to 1:1.

whats the stepping on your CPU?

I'm really liking that fsb so far...... :D

Nice :)
Let it run overnight at 1.536v and test for us if the cpu will survive that voltage. ;)

Batch #s: Q745A356 - Reading is fundamental. It's right in the first post. And it's not the stepping it's the batch code. These are all 6 Stepping with the C0 Revision. ;)

Stepping is C0, is this any different from all other E8400s? :confused:

First of all, that is DDR2 800 rated/binned ram doing 1280, second, I had issues booting 1:1 on the 333 strap past DDR2 1000 at 500 fsb.

Longevity at that vcore is what we're all concerned with...I'm going to take it easy with mine for a while... :)

temp h20 please? and the pack date,,,,
thanks ,,,,,,,,, and congragts for the awesome clock! :)

I'm running at room temp here, no windows open - probably 25-28c. pack date is 12/27/2007.

Almost 4.8GHz 1M below 1.6V :shocked:

Awesome CPU, now pump some more voltage into your RAM if you have a fan over them.

I have to change my pants now.........

It gets better:

I could get 4.9, but not stable enough for a screenie. Damn ram... :(

That is one Cherry chip. Enjoy Enjoy Enjoy!

Holy crap man :woot:

Nice clockin Zuck:up: .Same ram/cpu here.500ish is all on 1:1(5-5-5-15-42).Will loosen timings and change divider.

Wow that is a golden chip for sure, so far I have seen no signs of retails doing any worse than ES, rather the opposite. :p:

I really really wish they were in stock also over here, I can't wait any longer. :(

PS, I'm liking those numbers in the Everest mem bench. :)

well figure it out

RAM isn't holding you back

basically the CPU is maxing out there

i've got similar chip to yours that can prime with slightly less vcore as same clocks and i could only get 4.7GHz 8M SuperPi from a quick 1 hour bench session and around 4.9x validation. my ambients were around 26-27C from memory

when you stick it on something colder you'll be able to do some easy 5ghz+ benches

i'm FSB limited on 9xmulti (half multies not functioning atm) so highest benches were at 5.22GHz so far

who cares what its rated for...
ratings mean nothing in overclocking.

and if you have troubles booting at 1:1, you might say the board was the problem, not the ram.

you wanna get pissy with someone, you might want to pick your fight elsewhere, cause I'm not easily fooled, I aint a noob, and I do look at the details and question things.

If you were having troubles with the board, maybe you should have said that instead.

what is ur Max stable clock and what Vcore?

I care what it's rated for; it means I'm not trying to kill my ram, I'm going to push to MY comfort levels. Or may be I should give it 2.6v - 3.0v for 1500mhz and kill it? I know the peculiarities of this ram with this board, so save me the arm-chair quarter-backing.

I haven't tried any serious stability testing yet. I'm planning to run 4.2Ghz for everyday with 1.3125v

is this on water?

It is on water, "Cooling: TT Bigwater 745 + Apogee GT WB" was on the first post! Zucker2k, what is your load temperature?

Not trying to kill the ram, but taking the fast lane to a fried cpu?

I applaude you on your clocking here, but you need to reserve your hostility towards Kunaak, as its not warranted.

Take the ebbs with the flows dude. Sorry.
