Retail E8600 Overclock, Temps, Settings Thread

[chuxle]

Vader-at, looks like you have a very good chip.

We'll wait for 4.5+ results.

[BlueAqua]

I just picked up an E8400 EO from Microcenter in Minneapolis. I walked in and they were just putting them on the shelves. I'll see how it differs to the E8600.

[modderwannabe]

here's what i've got on my new rig ... any comments or suggestions are welcomed

[Brahmzy]

Hey Everyone

Think I got a decent chip over here.
Batch Q822A435
VID=1.21250
Pack date 07/21/08
100% stable on all accounts.
Prime stable 4.0GHz with 1.14V LOAD
4.4GHz 1.32V LOAD



Might try 4.45-4.5 later but am very happy with this result so far.
Cheers

Yup, that's where most every E8600 is at on air. 4.4GHz with 1.32V. I think you'll find the jump to 4.5 is a tough one. Lots of volts and heat, just to get the nice round number of 4.5. Mine will do it, but it takes way too much volts and pours the heat on - same with almost every other one on air that I have read about.

I have same VID chip. 1,2125VID
1,325V bios boot @ 4500mhz. Prime stable 25min. Didnt want to waste more time to Prime.
Also 600FSB stable on Rampage Extreme . All elements aircooled. CPU cooled by Scythe Samurai Master.

Batch / FPO# pls?

[Kristoferr]

rabor, FPO is q822a462
My first bad chip was q822a438
First did 1,31V 4000mhz
thisone does 1,158V 4000mhz

[RCG_Bex]

Ok, well I think I must have 1 hell of a wierd chip because I tried 1.25v in the BIOS trying to go from 4GHZ to 4.5GHZ (I'm having huge issues with my Overclocks) and bar from DET RAM (which I then sorted.... kinda) I tweaked and it almost booted all the way into Windows I think I actually needed to raise the voltages else where because I booted all the way in with a bit more to the NB and such which was on auto.... If I could get this damn BIOS to stop telling my RAM to off I think I'd have something good on the go here!

please do .. eye am haveing a hard time thinking a new E8600 is any better than my current E8400 .. so far eye am getting the same numbers at 4.5 to 4.7 as all the E8600 seen here in this thread

was really hopeing an 8600 would do 5.0 aroung 1.40~1.45 volts at least !

heck eye can get 5.0 at 1.536 volts in auto bios 1.48 real in windows

Excellent.. another nice FPO to look for

Those A438's really are dogs.. had one too . Glad you found a good one.

[x2s3w4]

Here's mine. I'm board limited, my P5B deluxe doesn't fully support the E8600. For more info read here.

Here it is with voltage on auto.

Here it is with the lowest voltage I could set manually.

Here's the highest I could go with the voltage issue.

Here's the VID.

Did I miss any info you needed? RAM is Kingston HyperX 1066. GPU 8800 GTS 320 mb.

The cheapest e8600 is $279 at newegg.com and not even q822 like in Europe.

I picked up this e8500 E0 at Fry's for $189 with a free ECS G31T-M mobo.

Same performance for $89 less plus a mobo for the girlfriend, lol!

This chip can do this on air:


But for cooler temps for 24/7 it runs at this:


This is on a cheap DS3L mobo too. Discovered it needed active northbridge cooling after it kept crashing after exactly 18 min 30 sec during orthos for anything above 4.3ghz. Doublesided taped an old DFI Lanparty NB fan on the NB and runs orthos no problems now.

So short of the magical European q822a e8600's these e8500 E0's are on par with the q820a e8600's for $89 less.

Hey gang,

Been a while since I posted, but I have been lurking around...

I just got my E8600 installed an hour ago...

I am a bit worried about my idle temps. Core Temp says I'm at 41C at idle. This is with an Ultra 120 extreme and a 120mm 80+ cfm Panaflo at full speed on stock voltage. I have AS5 as the compound.

The thing that bothers me is that the chip I just took out was running 1.34375v and it idled at 29C. How can a chip using less voltage run hotter?

I did look for light between the sink and ihs, but saw none.

What do ya think?

[LagunaX]

You need to do the washer mod for your TRUE. Made all the difference for one of my rigs.

[Geebs]

I had that going at one time, just to stop the damn thing from spinning on the ihs... You really think it will help with my temps?

Read this thread. Yes. B4 the mod I had uneven core temps (10 deg c difference) and ran almost 8 deg c higher too. After the mod my temps are lower and equal for both cores on an e8600es @ 4.3ghz.

I would recommend between a dime to penny thickness even metal washer.

[Geebs]

I was just reading that thread. Thanks for the link, and the suggestion

It seems that my new cpu must be slightly convex or concave... My TRUE worked nicely on my old chip, even without the mod.

I am considering lapping the ihs, but as I have never done it, I am worried I'll feck it all up. But ah sure, we'll see

Thanks again

[LagunaX]

Not that hard to lap.
Flat surface (glass, clipboard, etc.) and $4 combo sandpaper pack at autoparts store (400/600/800 grit - some say finer grit 800 up to 2000).
Up and down (not circular) 10 times, rotate 90 deg, 10 times, etc. until you turned 4 times with 400.
Repeat with 600. Then 800.
You don't need a shiny surface - just a flat one without big scratches (hence 800).
Also, you don't need to get down to all copper either (though it is nice for a better thermal gradient) - just a flat surface.
This will void your warranty though (as does overclocking lol...)

They don't have e8600's there yet but they do have E0 e8400's/e8500's.

Funny thing is that it is $10 cheaper to get the ECS mobo combo deal than the retail cpu alone, but that combo deal ended today.

Fry's in Fountain Valley. They still have older C0 stock so at the checkout you have to tell them to get the smaller box with the SLB9J (e8400) or SLBJK (e8500) code. But it is easier tell them that there are 2 sizes and you want the smaller one.

Got my Q822A435 doing 1 hour of OCCT stable at 4.5GHz at 1.304V.

Ya, I had the codes but didn't realize anyone had E0's yet. I can't justify a E8600 when E0's are available. Goin there first thing tommorrow.

Thanks!

btw... 8500 SLB9K (E0)

Just got mine today batch Q820A306 also a Evga 780i FTW

Where did you get it? First Q814 Ive seen.
