The Official Opteron 939 Overclocking Thread

[dnottis]

i just got a 148 from newegg with this stepping and was able to hit 3.03 (10x303) on it with 1.54v (in bios. cpu-z shows 1.52) with a zalman 9550

How stable? Prime, occt?

For those wondering what the CAB2E 0545 CPAW can do, although I have not really tested this chip in depth:

[yasoumalaka]

How has your mem bandwidth improved with these chips. Mine has been the same at lower speeds. I can't get the patriot back to ddr600 1t though, but like I said the same bandwidth. So I thgink these chips are also very cool in regard to mem bandwidth too.

HI,
Please can someone tell me which memory would be the best for ocing opty 144 I haave a chance to buy XMS3202v5.2 but no idea if it is any goood, the timing are 2-3-3-5 Thx

Right now the Samsung UCCC gigabyte sticks are very solid and the best buy for overclockers, IMHO.

You find them in G.Skill PC4000 HZ, OCZ PC4000 Gold (the GX has the new heatspreaders, very sexy IMHO) and the black Mushkin PC4000.

The G.Skill just dropped to $205 shipped, the GX is to be had with a MIR for $235 and you can get one stick of the mushkin for $99 after MIR (unfortunately newegg in their wisdom put a one-MIR per household limit on the MIR so no dual-channel that way, idiots).

This what I have gotten so far with Air-Cooling...

Stepping...

Same steppin I just got from Mwave.......Gonna get a DFI expert board.

[dnottis]

UGP - holy crap man - very nice. Where was that CPU from, 'egg?

One of the best steppings ever

(see my sig )

from Mwave.com

[ugp]

Got mine from ZZF for $238.00 Free 2ND day Shipping. Going to put it under water block soon and that is with IHS Intact

[ugp]

Still have to test for stability though. All has been 3DMark01 and 05 and Super Pi 1MB Stable atleast..

[Rustler]

I am tinking about water cooling but I am going to build a separate box for thix one.

[szukalski]

Here's my 148 CABYE 0543FPMW on my Big Typhoon, daily settings. 273x11 @ 1.500v :

[Mongoose420]

very nice. why running 2T cmd rate? 2gigs of memory?

[axion]

Nice OC szukalski, and wow you're from NZ me too :>

Yeah, 4x512Mb of TMSP BH-UTT. I'd like to see 2x1G sticks do those timings!
I'd be first in line to buy if they could heh.

[szukalski]

Nice OC szukalski, and wow you're from NZ me too :>

Born and bred. You in aucks?

Add me to msn if you want, the addy's in the profile, always good to have an NZ overclockers network.

[ugp]

I might have to take a try at taht 273x11.0 @ v1.500 and see if it is Prime Stable...

[tsuehpsyde]

Finally got my Opteron under water. 37C load on 1.4v @ 2.95GHz (CABNE 0530APMW). 3GHz was stable with 1.45v for 8 minutes before Prime95 failed, and since I'm a stabability slut I dropped her down to 2.95GHz for now, until I get some more free time to tweak it.

I'll post some screenshots when I can, the highest I got was 45 minutes Prime stable @ my current settings, which for now is good enough.

[TMM]

Hey guys, im having trouble getting my Opty prime stable. I can prime @ 2740mhz~ @ 1.40v for hours without errors, but i can't quite get 2800mhz stable.
The odd thing is, i can run 2980mhz @ 1.54v through SuperPi 1M, and get a screenshot of 3080mhz @ 1.58v, but i can't prime for more then half an hour on 2800mhz @ 1.52v.
It just seems odd that there is such a large difference between "benchable" clocks and 100% primeable clocks. Heat shouldn't be an issue as i was previously running a 3200+ @ 1.65v, 2600mhz prime stable (10hr+) on the same setup. I've reseated the HSF (xp-120) twice, with no better results, or no worse for that matter.

So far i've done about 20hours of CPUBurnK7 (2 overnight sessions, 10 hours) to try and burn it in, but it doesn't seem to be doing much.

Ideas?

[mascaras]

my opty 148 CABYE 0543 FPMW arrive next monday , i will post results then , i hope it is good , so far for what i saw in the forum its not a bad steping , i have WC , DFI ULTRA-D and 2x512MB BH5 , lets see what i get .

[Txaime]

My CAB2E 0545 CPMW is at 2700 MHz with 1.408 volts. Still needs burning in...Failed prime 4 times at this speed, 1st for 17 mins, then 22, then 35, and now its been priming for over an hour *touches wood like mad*

Is it just me, or do these chips run quite hot? I'm at 44*C under full load at these speeds and volts.....My venice which does 2610 MHz didnt exceed 44*C at even 1.53 volts.

Ajam good results, please put your new results!.

[ugp]

How much of a factor does burning-in help? And what is the best way to actually do a burn-in?

I have always just slapped them in and clocked them.
