**Official e8400/e8500 Retail OC Thread

[doakh]

Well I really notice any significant performance improvement while running applications if I upgrade from an e6600 to e8400? The price seems very reasonable and I am very tempted.

[panfist]

Has anyone been able to get the e8400 going with an ASUS p5n32-e SLI plus? If so please let me know what you did or what BIOS version you're using.

Whats the word on air cooling results?

I got it to work on my Striker Extreme which is very similar. Some beta bios 1501 is the best one I found for my E8400 on it. ~515 FSB

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

Hey everyone, I'm originally from ocforums.com so don't hate too much

Anyways, I'm having a problem getting my retail E8400 prime stable @ 4.5GHz. Heres my original thread on ocforums, http://www.ocforums.com/showthread.php?t=544212

My current setup consists of a lapped E8400 (batch Q746A381), a lapped Thermalright Ultra 120 Extreme, 4GB of G-Skill DDR2-8000, Abit IP35-E (BIOS 14) and a Corsair HX620 PSU.

Basically is that the best BIOS for overclocking Wolfdales with? I have my NB @ 1.41 volts, SB @ 1.6, CPU VTT @ 1.23, and vcore @ 1.58actual after vdroop (according to CPU-Z). That voltage seems kinda high for only 4.5GHz, so I'm wondering if theres some other voltage I'm not increasing enough. I haven't seen many (or any at all) Wolfdale results on the IP35-E, so I don't exactly know what I'm shooting for. I know my RAM is capable of running 530MHz FSB, and I took my board that high on my old E6300.

play about with the CPU PLL volts a bit, more NB might help also.

Nice clock otherwise

Hello I'm Spanish.

Sorry by my bad English.

Today arrived my new 8400 and set to this clock stable.



My problem is temp

Idle: 43-44 with my Thermalright Ultra 120

It's normal ?

Have you tried to reseat the cooler? If that doesnt help see if the paste is spread properly.

[Damien]

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

cpu-z isn't showing correctly, it's at 4.4 i believe from the window below superpi

Checked two things and nothing.

Should I rma this processor ?

[danmoody]

Boys and Girls....

It's up to you, but gives us all a break and post your max stuff... give it time and pile it on.

Danmoody.... You made it official ...You going to make an excel sheet and update the first post?

Grim Reaper pretty much hit the nail on the head

Or is there a wolfdale one going already?

I didnt know there was more to it then just making the thread sorry for being a noob

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

[Shampoo]

Baaaaah, I think I have a dud.

I have a separate thread going here and in a P5N-E SLI thread at anandtech forums.

Batch: Q740A523
Packdate: 12/20/07.

I'm priming right now 450x9 @ 1.360-1.376vcore, according to cpu-z.

Failed orthos after 20mins when I had it a couple ticks down from the current vcore setting in the bios.

I'm hitting temps of Core0:57, Core1:58 with a Thermalright Ultra 120 Extreme with a Vantec Stealth 120mm fan in a P182 case, but currently being run on its side and open front and side panels.

Kinda toasty. I wish I could've gotten a good chip for once!! Like (sorry forgot name) watery?

I thought I'd get lucky and get one that could stay under 50 degrees at over 4GHz, but nooooooooo, I'm struggling to get it stable at 4GHz with high voltage. Bah!!!!!

I've got another one of these of the same batch sitting at the office for a client's system, which will never see overclocking. I wonder if I should test that sucker out first.

I don't think it will do much better since it's from the same batch.

I should be happy nonetheless since it wasn't officially confirmed my 650i sli chipset could handle these processors, or my motherboard for that matter, Asus P5N-E SLI. (bios 0803)

[Truckchase!]

I didnt know there was more to it then just making the thread sorry for being a noob

Dan do you want to do it? We could see if we could get some admin help and such.....

On an on-topic note, mine did a full 24 hr prime @ 4130 @ 1.375v (BIOS set). Stepping info and such is above.

Did anyone notice that vDroop on the wolfdale chips seems to be significantly more prevalent on the same boards? I had .2v difference between my set bios vCore and my reported vCore on my Conroe, where as the diff with the Wolfdale is like .4v.

[Shampoo]

Okay I'm up to 1.408v on the cpu.

Orthos failed at a previous attempt after 48mins.

I'm losing hope.

Could be the board of course, since P5N-E SLI boards don't have official bios for these cpus yet.

I couldn't get my E6400 or E6420 stable at 450 FSB, so maybe it IS the board.

Thinking about picking up a P5K-E anyways.

[nzbleach]

[Shampoo]

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.

[Kunaak]

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.

[Shampoo]

I guess I have to wait for a bios release or just go out and pick up a P5K-E, because I just ran stock settings and it failed orthos and froze my system within a few seconds (30seconds to 1min).

[BlueAqua]

Phase change.

Max FSB:


Max Mhz


Max stable PI in my short bench session:

[turtleonviagra]

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

[Penguin463]

Glad to see that intel's new dual cores have some decent headroom for OC's

Keep em comin guys
