The Official Opteron 939 Overclocking Thread

[uOpt]

Did I already report in with my Operon? Sorry if so, can't find a post by me.

Hi, my name is Daniel from www.aquapc.com and this is my contribution


As you can see my 148 is just like the fx57 weeeee lol

My Opteron 148 has exactly the same codes as your Opteron 148 and your FX-57 (CABNE 0528 GPMW).



I didn't play with it too much, except I know it does 2.9 GHz at stock volts (which appears to be 1.4 V).

Now I am unsure whether I make it a server chip and never overvolt it. I wouldn't like to overvolt and only reach 3.1 GHz. But what if I could reach 3.5?

Decisions, decisions...

Recieved my second 148 cabye today, my first one of these does 3.0ghz 1Mb Super Pi stable. The new one is 1Mb Super Pi stable at 3.1ghz using 1.7v.

27.5 seconds for the 1Mb test.

I've got a 144 cabne coming in the next day or two, can't wait to see how high it will go now

This i can do easy... no tiimings modified... it was runing 3-3-3 lol

at 3.7 ghz i cant run superpi



tomorow i´ll try a rdx200 on the promy with a decent power suply, the fFPS Group that i got here it´s not that good...

[Jesse71]

Nice o/c, but why you use olds versions of CPU-Z ?

i CPU-z shot of 3.7GHz+ will give you a world record OC so get cracking heheh

[DDaniel]

a ss of 3.7 its on this page..

[gbomb944]

That's pretty amazing the gskill guys opty. All his multi's work and the a64 extensions are there apparently. Also amazing how nobody seemed to notice or care even after Gundamnit pointed it out.

How do you get so lucky as to be a gskill tech so you get pimp ram for free and somehow unlock your opteron at the same time? Unbelievable.

Everybody clear cmos a hundred times and report back.

Hey guys I have a question.. What is the highest anyone has gotten on their Opty 146? Cuz this is what I just got..

http://valid.x86-secret.com/show_oc?id=46210

[Jester FPS]

wow, that opty clocks higher than most of the opty 148's i've seen. nice work, is it stable?

[njkid32]

wow, that opty clocks higher than most of the opty 148's i've seen. nice work, is it stable?

I only benched at 3.6ghz 1m but didnt try anymore. I just wanted to see how hight it would go. Hell I just stopped it at 3.7ghz I prolly could have gone higher but didnt. I'll give 3.7ghz 1m a try next.

[gbomb944]

what stepping. cabne no doubt?

[njkid32]

Here it is.....

[RacerX]

hmm, not superpi stable but for a CABGE its a accomplishment.

[dogsx2]

Here it is.....

What kind of Vcore was that?

[njkid32]

Well I did pump it up but for my cooling it should be ok but not for long periods of time.

[tico]

isnt that damn close to the world record?^^

[dogsx2]

isnt that damn close to the world record?^^

Nay, I've seen higher Vcore on a 939.

wow. that has me going cuz i got the same cpu and all. i just havent gone up to 1.6. thats not for me. good to know that wafer has the potential tho. wow. 3.7, oh my.

[Diverge]

Here is the highest i've taken my opty to (air cooled @ 1.55V): 2.9GHz http://valid.x86-secret.com/show_oc?id=46234

I plan to try for higher, and haven't run prime or superpi yet at 2.9, but at 2.8 it passed occt stability test. This is a totally new board and cpu, so it's having other issues atm with the motherboard and ram compatibility. Also, so far i haven't been able to get this cpu past 41-42°C with prime or occt at 2.8... gonna stress it at 2.9 and see what happens.

Edit: it just failed the torture tests, i guess it needs another bump in vcore.

Anyone clocking those with Vapo LS ? I am just confused , my Opteron 146 (CABYE 0536GPMW) @ 3100MHz , with only 1.55V shows ... +7C loaded
Is it something wrong ? I just dont get it . Remounted evep. couple times and no improvements Are they realy THAT Hot ?



Max. bench speed so far is 3250MHz @ 1.64V , passes 3DMarks and Super PI 1M (didnt try higher yet) . No improvements from going to higher Vcore , probably cause it get too Hot ... with Vapo LS ... Seems like a bad match for my VX4000 , that wont run over 260 @ 2.0-2-2-5 no matter what voltage i am providing , because of lame dividers . Only managed to get 25.98 super pi 1M , because of low mem. frequency , 232MHz @ 2.0-2-2-5 .... Damn mem. wont run next level of 270MHz ...



PS , What is the best BIOS to use with those Opterons and DFI LP UT nF4 SLI-DR ? Any help will be highly appreciated !

Flashed 623-3 BIOS and it keeps going up !

[Damien]

Would leaving all the memory timing options in DFI bios to "auto" possibly make the cpu unstable or would it not do that at all?

Awesome temps on my Opteron 146 CABYE 0540 FPBW

How does this compare to each of your Opteron 144 CABYE 0536 GPMWs? Lower volts but higher temps? I made it to 3ghz easy with my 146 CABYE 0536 GPMW but the volts beyond that scale up dramatically and the idle temps climb from the low 30s to the high 30s. Load temps in the mid 40s but I think I'll have to go to 1.7v if I'm going to get to 3.1ghz 32M stable. Only one of the 3 Opties I've tested made it to 3.1ghz 32m stable on water. Two of them came up a little short which I suspect will also be the fate of the 146 CABYE 0536 GPMW. How does my 59C MAxTCase rating compare with both your CABYE 0536 GPMWs?
