The Official Opteron 939 Overclocking Thread

OMG k00lance!!

I seriously did not expect that chip to do that well. VERY interesting. Then again you must really know what you're doing. ;)

Ozzi,

You have number 1 on the way. You should beat everyone here. I will beat you if you don't. :slapass:

haha j/k

When Super Pi errors out like that, it means one thing, instability.

Now, the instability can be a number of things, so start testing different configs to find out which component it is.

From now on, don't hijack a thread :)

oohhhk buddy. it was prime95 and i'll take any other answers :P

vandi!!! thanks for my chip!

el rolio....it means it's unstable at that speed. Lower your clockspeed.

thanks vapor. so not a thing aboutt voltage necessarily or anything right?

wow k00lance, thats downright amazing what your chip has done. mine is giving me issues around 2.9 but then again ive just been tryin to burn it in, high temps and vcore and all... not really trying to acheive my oc. but goddamn thats what i want 300x10 and call it a day.
good job mane!

i'm seriously banking on it :D

eva, i've noticed this too, and summed it up to be normal. he was getting around 10% higher bandwidth. a good amount, but nothing to poop myself over :toast:

I will post my tweaker shot as soon as I get home. The comp locks up when I try and change my preamble from 5ns to 7.5ns....that should be loosening the timings right? Why would that lock it up?

Because it's so drastic....you should set preamble and MAL in BIOS.

Ok got my Opteron yesterday, here are my results so far.

I got it from Ewiz, Opteron 148 CABYE 0528GPMW.

SO far I got it up to 255 x 11 = 2805 mghz @ 1.4V. Memory is on a divider 200 2.2.2.5 2.8V. So I figure, alright I hit a ceiling with 1.4V, let me step it up to 1.45 and take it from there. Nothing happens. Going to a slight increase of 2850 mhz, even under 1.6V, Prime errors out. So basically does this CPU not scale? Seems like no matter what Volts, the ceiling is 2805. I just hope the reason is I'm testing it on an old Asus A8V Deluxe, as my other mobo is being RMAd, but still. I set my memory on a lowest divider, so it would not interfere.

A64Tweaker also hard locks my comp when I try to change the Cas Latency from 2 to 3, I'm making it looser so what's the problem? All other options work fine without a problem, except Cas Latency.

I know the screenie is showing different things than from what I described, it is because I'm testing. It is stable at the settings I mentioned earlier. I put 1.5V and loosened memory to 3.4.4.8 just to test.

I did this 2min after it was out of the box.
Special thanks to you vandi :D
I want to see what this cpu will max out at 1.392 v :D :D

k00lance .....whoa stock cooling...congrats mate......keep the screens coming

funny thing....I have exactly the same 1M SuperPI time at 2970MHz, 270MHz on RAM......but you've got sooo much to go still....amazing CPU

would you mind showing us your ram settings?

[QUOTE]would you mind showing us your ram settings?[QUOTE]
I barrowed that ram from my neighbor and he is sleeping right now ^^


I've got an fx-57 today that has the exact same step/week as this opteron :D
Drooling what these will do ^^

Ahhhh, always good to see a pic showing my Opty is the same stepping/week as a CPU 4+ times what I paid :D

Are the serial numbers very similar? The 2d barcode is certainly very similar.

Anyone got the 150 OPTERON, how does this one do ? The 146 aren't available here where I live, only the 150.

Oh Yeah that´s my Stepping here at my CABNE1460530APMW Batch G50 072
And it runs really Good. Damn Good on Air.

I don't like 10x multi.
Opty can never battle fx's
But i like low voltage 3ghz :D

Of Course can a Opty battle an FX.
I´m on Aircooling and soon i will get my Watercooling and than i can really go further up to 3,1Gig oder 3,2 Gig Primestable. My Temps are too high under Prime over 3 Gig!! :(

Just got my Opteron146. DAMNN it is the CABGE stepping :( :
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.
