A few words on E8600 Q820A599

[Monstru]

Well....after a long, long wait I got my CPU from lolhalol (which I would personally like to thank once again for helping me out). After I received my little treasure I decided to take a few test with it before putting it under LN2 (anyway I've got no LN2 now and I have to go to Amsterdam, so that will have to wait for a few weeks) so I played a little bit with air, chilled water and a single stage....


Air

29 oC Room Temp

Cooler Master Gemini II
MSI P45 Platinum
Crucial Ballistix PC8000

SuperPI - 4000MHz - 1.14v
Orthos - 4000MHz - 1.16v
SuperPI - 4500MHz - 1.33v
SuperPI - 5000MHz - 1.56v



Chilled water

Cooler Master Aquagate MAX + water + antifreeze + ice
MSI P45 Platinum
Crucial Ballistix PC8000


SuperPI 1M - 5200MHz - 1.7v / ~ -5oC

Too much vcore here, but I just wanted to see how the CPU does with higher VCore...

Single Stage

Dimastech SS
Asus Commando
Crucial Ballistix PC8000

SuperPI 32M - 5200MHz - 1.6v / -40oC
SuperPI 1M - 5500MHz - 1.6v
Max Screen - 5760MHz - 1.78v / -35oC

Unfortunately all my valid files >5500MHz are corrupt



I am pretty pleased with the way this baby goes, and I can hardly wait to put it under the real cold....-100 should be a blast

[Jakalwarrior]

4ghz stable at 1.16... nice chip!

[WrigleyVillain]

^ Indeed. Looking forward to more too...

On a side note, I wish I "had" to go to Amsterdam.

[Monstru]

Well...I have to..for the MSI OC Contest...they made me do it

[chispy]

Nice chip you got there Monstru , i like those results on low voltage. What batch and vid ?

[Monstru]

Batch is written in title, Q820A599. Vid....1.23 on Commando...1.10 on MSI P45, with the same CoreTemp version ( 0.99.1)....weird

[REVHEAD]

You should put this in http://www.xtremesystems.org/forums/...d.php?t=197505 allready a highly active thread on the E8600

[Monstru]

Unfortunately I saw that thread after I made this one. I posted a link there

[giorgos th.]

i cant say i`m very pleased with my Q822A...i expected ~100mhz more with that voltage...SS at -42C..this piece was very hot...25C difference from coretemp - evap temp..

[Monstru]

It will do more with that voltage giorgos, but not with that temp

[giorgos th.]

yeah i know my friend....it was a bit dissapointing...

[Nanok]

I got same batch.

[Monstru]

Nice one

[eva2000]

nearly all Aussie stock is this batch even 3 weeks after they showed up in Australia!

mine arrived yesterday

5x E8600 are Q820A599 SLB9L 07/15/2008

[Monstru]

Nice stock you have there

[eva2000]

thanks

1st of 5x E8600 Q820A599 installed on Gigabyte EP45 Extreme with new F6H bios. VID = 1.25v and seems to be around 0.032v vdroop on Vcore under load.

who said E8600 were hot buggers ?

Some more playing with SS, can't wait to get back from Amsterdam and hit this baby with LN2

SuperPI 32M - 5400MHz - 1.62v

Don't look at the score, no tweaks there, just testing the CPU

[eva2000]

nice clocks there..

3rd of 5x E8600 Q820A599 installed on Gigabyte EP45 Extreme with new F6H bios. VID = 1.25v is same as 1st E8600 Q820A599 **5146.

Finished quick tests for 3rd E8600 Q820A599 **0537 so far coolest running E8600 out of the 3 tested and highest cpuz validation and 1M pi







Summary for quick tests at http://i4memory.com/95144-post31.html

[eva2000]

Here's latest results tabulated - 4th cpu ain't as good compared to the others on H20.

[Dee]

Mine is Q820A670 -- very close # to Monstru's chip. VID is 1.2500V.

I had it up to 4GHz so far. No big deal, but I am still using the crappy stock cooler until I can afford something better. It took 1.325V (in BIOS) to do this, although CPU-Z reported 1.288V, so somethig somewhere is slightly off.

My Pi times @ 400x10 so far:

Just testing E8600 Q820A599 **0464

[eva2000]

Different board test, I flashed to 8/29 bios before installing my E8600 Q820A599 so lucky not to have any issues with setting vcore - so much so managed 4980Mhz at 1.55v bios set with Corsair Nautilus 500 H20 cooling for 3dmark05 http://i4memory.com/showthread.php?t=9904 !

[Monstru]

Finally some LN2 preliminary preparations

6350MHz - SuperPI 1M - 1.84v / ~-120 oC

Please do not look at the performance, I was just testing the CPU.

I think it;s a promising one

[loonym]

Wow, very nice Monstru! That's some good ram kits too
