Overclocked my Retail E8400...WOW!

[Xvys]

Got my E8400 this morning, batch Q740A555T. I just did some preliminary tests and I must say I am amazed! With default bios settings my E6300 did SuperPi 1M in 30.0 sec. I plopped in the E8400 at default and it did the 1m in 15.0 sec. Of course SuperPi is cache-centric, but a nice speed boost. The cpu vid is 1.1125v.

I o/c to 400 fsb and the vCore set to 1.28 automatically. All was well. So I tried the bios NOX o/c at 30% and Windows would not load. Then I manually set the bios on 460 (for no particular reason) and set the vCore to 1.40v and vDimm at 1.21v, with all the other voltages at or near their lowest settings. And so far totally stable at 4140Mhz! I have not tried to lower the voltage or increase the FSB as the most of the monitoring programs do not work. TAT does not open, SpeedFan does not show core temps and CoreTemp shows 15C on one core and 34C on the other. Under load the one core went up to 28C while the other did not move from 34C. So obviously some software upgrades are necessary before any serious o/c.

here is my on air



and this 1 is on SS



I reached the limit of my P5B-D can't go any more.

[AngryArtichoke]

wow thats cool

[eternaljammer]

I just may have to get in on one of these. They seem to oc very well.

[Envydia007]

4GHz is just normal to this chip.

Stop teasing us with Wolfdale results, i'm going crazy if i haven't got one by the end of next week.

Nice CPU's though.

where did you get yours from? There are many places with them today.

sorry , I hope you get a nice chip too, I can boot straight in windows on 4050Mhz 1.256vcore and can do super Pi 32M.

[eToh]

Great cpu's indeed/ You can now get these on eBay for around $210.00

Nice o/c icewater! I bought mine at my local computer store in Vancouver, B.C ($US 215). I won't mention their name in case of non-disclosure issues

One concern I have is the discrepancy between the core temps? One registers 17C, which is about 7C under ambient temp, and the other core is stuck at 34c and does not change? At least the one core's temp does go up to 28C under load.

I suspect this is a mb sensor issue, or perhaps my heatsink is not installed correctly and only cooling half the cpu? So if the cpu throttle down is 105C, it looks like I have plenty of o/c room!

[CERO]

Nice , I assume u used the P5K deluxe for this chip, what Bios u use?

[WiTcHkInG]

Nice results.
Might have to sell my spare Q6600 and get one of these. If they stay instock long enough here in the uk

I am using the latest 705 bios for the P5K Deluxe

I don't if my mboard sensor is correct, but they are 44 and 46 degree on 1.256v. but when tounch my Hsink's base it not even warm.

Thats what I did today.
Bourght an E8400 today then listed my Q6600 on ebay and it sold in only 1 hour, I did'nt loose too much so it's an upgrade almost for free.
Hope the E8400 will be a good clocker as i've got a SS.

Thanks for your post Xvys/icewater, you convinced me to get some wolfdale therapy

Where's everyone getting these CPU's from

I want one too

[Bail_w]

Micro Center, go try the santa clara ca one.

[Xvys]

I still have the issue of one core reading 6C below room temperature in programs like Asus Probe II, CoreTemp, Everest and CPUID monitor...while the other core idles at 34C, which is probably correct. Perhaps they disable or throttle down one core to save power at idle? But both cores went up to 50C when I tested Orthos stability. So far so good.

I cranked it up a notch to see if I could match Icywater on air, and it looks like I beat him by a tick to 1M... Mind you there is much fine tuning still to be done and plenty of headroom left, and perhaps with an 8 multiplier (or 8.5?)...

[TMonte]

Nice results...hope my wk 40 does as well as yours.

[bt_medic04]

cant wait to pick one up to replace my owned for 1 month E6750

[BlueAqua]

Can the Striker Extreme handle Wolfdales?? Yes yes it can.

[Seer]

Micro Center, go try the santa clara ca one.

That's about a 1.5hour drive away

[Bail_w]

That's about a 1.5hour drive away

Yep, its about 1 hour for me, so i am not going to drive there.

[DoObs]

These chips are really impressive, Can't wait to get mine.

soon as i sell 1Days E6420 i got from her, going to get one of these babies.

5ghz under 10 SP, thats just insane

[clon22]

Poison!!!.
Can't wait to get one to try.
kekeke...
