The Official Opteron 939 Overclocking Thread

Nice! My store has again 144 on stock and they will send it to me today.
Steppings are all CABYE 0536. At least i'm not getting the worse (i hope) :)
Cannot wait to put my hands on it :D

what about this serial? Witch is the best? What can I expect from this cpu?
CABYE 0536GPMW
CABGE 0534

CABYE is better....expect somewhere marginally below 3GHz.

with witch kind of cooling?
thanks

Decent air I would guess. Some will be worse and some will be better of course...

Yes sure, just to have an idea thanks

Here is my 144 0530 APMW 0081er Batch at prime and 32M and 1M
Its without heatspreader. Under water.

the RamMHz at 32M is an error, it runs at 200/140

what mobo are you using?

What cooling? :slobber:

And I'm 99% sure he's using DFI as SmartGuardian doesn't play well with other boards from my understanding.

freestylercs: Where and when did ou buy it? I may buy one in Germany...

man wish i had a CABNE sweet 3.2ghz freestylercs!

Opteron 144 CABYE 0536 GPMW run @2906mhz at 1.52v

1M = 28.235S
8m = 5m 11.329s
32M = 24m 54.766s

yes it s a DFI SLI-DR.

Normal watercooling: Tripple radiator.

@Mats its one of the first 144er, here I bought this Opteron:

ebay.de

less than 200 €.

to cut the heatspreader is the best i´ve done.

(sorry for my english??)

There's A LOT of variation in water....for instance, mine's no better than a Big Typhoon while his is way ahead of it. :fact:

CABGE 0536VPAW. :mad:
Havent been priming or anything yet. But it wont do past 2650mhz. Not sure if it is stable at this setting though.

Doh :(. Where did you get it?

If I loosen the preamble or MAL in the BIOS the computer won't boot either. I can tighten them though. SInce I have DDR500 theses shouldn't be topping out at 215 right? Here is my tweaker shot...

Leave MAL at auto and set PA to 7.5ns.....it doesn't boot on an Opty?! Hmmmmmmm, let me think about this one--this is new.

EDIT: just looked at your tweaker shot and it's running a PA of 7.5ns, you should be good to go I think.

yeah. Seems strange to me....but i have no idea what the problem is. Ihave tried changing one at a time, both together, nothing works.

Don't change them in Windows if you can't, somethings just don't like to be changed....anyway, keep them at 8ns and 7.5ns respectively, most people have had their best OCs with those values.

Mine won't boot with read preamble at 7 either, i've heard it's a bios issue.
With bios 704-2bta it should be possible.

hey uhm if i post pics of my optie... i should block out the serial number in 3rd line? the one that tells g50 and 0120 batch? but block out the rest? why?

just a note. backed it down to 280x10 with mem on 183 divider

but ass soon as i get some rest so read tomorrow ima start the testing from scratch. i'm gettin higher temps than my winnie of course... and i think i mounted the storm block better this time, but i just dunno what to do. hmmz.

I think I tried it with 704-2bta but I can't remember....just recently backed down to 603. Hmmm...maybe I will give it a shot, right now I am testing single sticks. How long will OCZ accept RMA's for?

My PA is booting up at 5ns now... and my MAL is at 7. Not sure why it changed.

This CPU amazes me more and more every day, it passes OCCT test at 3000MHz with a lousy 1.39V. :eek:

Watercooled in an 20C ambient.

I have to be honest, this is single channel cause one of my RAM modules broke. :(

Hey Zeus,

Will be interested to see if you have a difference in OC once you are running dual channel again. Oh and I keep seeing you mention the voltage tht your CPU needs. Even though the software u use reads 1.39v I very much doubt tht the CPU is being given 1.39v. Only one way to find out (which we already discussed) but I imagine tht your brd is like the other DFI boards then your 1.39v is probably more like 1.44-1.48v! Big difference ;)
