Hello everyone,
I wonder where you will find the cpu so fortunate,
you can post links in private?

Hello everyone,
I wonder where you will find the cpu so fortunate,
you can post links in private?

Searching seek and buy... nothing more nothing less, unless you got a contact at Intel that cherry picks them for ya

we all write down batch nr's, etc... look on ebay , contact etailers etc... if they have one of the better batches go for it...

[PnoT]

Nice going Rolco , damn I wanted one of those E8200 from Nils you beat me to it, you madman !!!

Was there a nice batch of those running around? I'm wondering what volts he's putting to it for that high of a clock.

I'm also curious as to how many of you are adjusting your GTLs?

Here is mine but i'll have to admit i haven't pushed it or tweaked it much.

Wow, this has to be the best clocking chip I have seen. Don't get me wrong I've seen many E8400/E8500s @ around 4500MHz, but never with a Prime stability and a Vcore like yours.

That's true, geez Syl that looks like a great chip. Like the low VID. And 1.34Vcore for 4.42ghz 17hrs stable is real nice.. : )

Thanks guys This is a Q807A091 with a high wafer number of 91 from Tankguys. Although the chip has passed 1hr OCCT at 4.5GHz, small fft prime stability at my self-imposed max Vcore of 1.36v is much harder - so far 4.47GHz seems to be the limit.

[sauria]

Now im doing prime @ 4050MHz @ 1.282V

Aircooled (Scythe infinity and 5V silent fan)

Great! Thanks.

[tarantul]

hello again m8s.
So this is my E8400 (Q807А241) with screen @ Orthos. So i still have the problem with temp.. dunno what to do.. The voltage in Bios 1.2925, in Cpu-z 1.260, and 1.220-1.230 under load. (look screen)
but the temp under load is around 80.. (( system in signature.

Hello. Should I be worried if my E8400 uses 1.36V-1.368V on idle and around 1.33V load 24/7?

[CrazyNutz]

Hello. Should I be worried if my E8400 uses 1.36V-1.368V on idle and around 1.33V load 24/7?

As long as your temps are reasonable you should be safe. I run mine @ 1.360 idle, and 1.352 load 24/7 with no problems what so ever

My 8400 just plain sucks



Best OC without rising any voltages. It seems impossible to get it even 4GHz, I did try it with even 1.42* V from bios. No luck.

If I can run my computer with low multi (7) and 480 MHz bus, with 1:1 memory and all default voltages. If I rise multi, is it possible that I must rise nb/sb voltages?

What is this VID, core temp says 1.1125 V. I have it set from bios to 1.1 V, should I set it to 1.1125 V?

[max_87]

Just got my E8400. Currently priming at 4GHz @ 1.24v. One of the most effortless overclock for me to date

VID 0.9250v

4050 w/ 1.41v - certainly no low volt champ like some lucky folks here, but very stable and cool under water, besides vcore, nb volts needed a bump to 1.55v

Thanks, I just got a Q807 I need some time to build it now.

Could users with the new 45nm chips try using CPU-Z to report VID and compare that to what CoreTemp is saying?

If you go into the INI file for CPU-Z just set Sensor to OFF:

Sensor=OFF

and instead of it reporting your actual voltage it will display the VID of your chip.



I'm a little biased here as well. I just released RealTemp 2.5 which also displays VID and I'm interested in finding out which program is right. I think Intel and CPU-Z have a pretty close relationship and I tend to trust CPU-Z. I think CoreTemp might be reporting VID too low on the new 45nm chips.

Hi guys. First-time poster. Just had my account activated. Switched from Q6600 (which was not too bad, but OC is a pain). I must say that E8400 didn't give me a hard time at all.

System setup:
Case: CM Cosmos S, 3x intake(1x 250mm, 2x 120mm), 4x exhaust (3x low CFM top fan, 1x high CFM rear fan)
Cooling: Zalman CNPS 9700 LED w/ AS5
Mobo: ASUS Striker II Formula BIOS rev 1202, 1 Antec Spotcool fan sitting on top of the NB. NB/SB/NF200 sinks cleaned with isopropyl alcohol and AS5 applied.

Can't remember the processor lot/packdate out of my head but it's late March 2008. 1.1500 VID. I chuckled a bit when I saw "Max volt - 1.25v" on the box.

http://valid.x86-secret.com/show_oc.php?id=354966 - 1.38v
Crashed after Prime95 errored out.

http://valid.x86-secret.com/show_oc.php?id=354968 - 1.41v
Stable, but too dangerous temp (70'C)

Right now I'm running at 475x9 @ 1.38v. Prime95 is stable, OCCT hasn't complained at all after 8 hours. What I really like about this is my 3Dmark06 score went up by 2500 points, and five seconds off on SuperPi 1m (16s to 11s)

[ownage]

That is one kickass cpu


Keisuke: Welcome to XS

[Jupiler]

Very nice, webwilli (but I already told you that )


Here's a little update on my E8200.
Decided to push it a little more to see what this baby can do.
Ran Prime overnight (15 hours) at 4300Mhz, 1.344V. Not to shabby, IMO.

Funny. CPUZ reports my VID on my QX9650 as 1.238 while coretemp says 1.125
