The Official Opteron 939 Overclocking Thread

[wittekakker]

Are there any CABNE 0544 EPMW results yet?
Haven't seen them..

Recieved mine today (opty 146), but got to work, maybe I instal it tonight.

so what is this maxTcase all about?

Nothing really, some lower maxTcase will go higher then an other do visa versa.
Maybe look at the wattage instead because i see people getting higher clocks with higer wattage from maxTcase.

Looks like my sistem has a ram issue...cause I can pass Super_PI 32mb @ 210mhz and CPU 2950mhz...than changed to 250 2-2-2-5 v 3,2V and CPU @ 3ghz and can`t get more than 7 loops, S&M @90% CPU passed withouth any problems, but it gave me an error in ram test...so the CPU is stable but has some problems with rame divider or settings...cause OCCT fais within 3 minuets and prime in about 10 seconds at every VCORE and FSB I gave to the CPU (have tried only 280 and higher...)...

Yep I have the same issue, but for now i am at 2900mhz and ram synced with loosen up timings 3-4-3-7 prime stable.

...so you have the same issue with TCCD ram?...mhm...strange this...I was looking to sell my ram and go for TCCD but now...

Well i need to test more before i can confirm its my tccd but its more likely ram setting or memcontroller.
I am still testing raw cpu speed and not so much ram/memcontroller.

Still my ramsticks are weird, I think one stick of ram doesn't like voltage above 2.6V and the other one needs more voltage to go higher. Still need to test them sepertly but from what i've seen in memtest i am quiet sure.
With my venice the maxed out at DDR620 3-4-3-7 @ 2.6V.

At the moment 2.9ghz stable at 1.525V real voltage.

[SPivX]

well, tried my other 146 to see if my instability problems were caused by CPU, be that doesn't seem the case. It seems to have something to do with my m/b or memory. i still cannot run 270/280/290 x 10, but 300 x 7/8/9/10 is no problem! i wonder if you guys can still help me?

[kemist]

How good of an indicator is prime in real life usage as compared to say stability in spi32m and SnM? I have a proc that does ~2975 with 1.55v 32m stable, not sure about SnM. But it def does 2900 32m and SnM stable yet fails prime at 2900. To be fair though i think the prime issue may be related to memory/motherboard. Im using an epox 9nda3+ with gskill 2gb zx and i dont think the ram likes the motherboard. I really would like to know if anyone has played around with these processors on different mobos and seen large differences moving from one platform to another. At this point id like to say my mobo is the problem but i cant be sure.

What are you using to read voltage and temps in occt? Does it read the DFI board automatically or do you need to configure it using something like speedfan? thanks.

[Primoz78]

I think he is using MBM...as I can see from the screenshot...

Duh. I feel like a dum dum. thanks man.

[187(V)URD@]

Well i am using speedfan for OCCT because OCCT takes my MBM dashboard away when mplented in OCCT.
So i basicly use both.

[smartasien]

Just wondering if 350x8 or 280x10 is better if the memory speed is the same for both.

[ic3m4n2005]

@smartasian: performance should be the same.

htt link speeds may differ. try both and bench and compare results.

update: after tweaking ram settings with a64 tweaker it seems it has stabilized me at least somewhat, i'm now at 2950 with higher ram timings that, if i had tried booting at this speed with these settings without the a64tweaks it would have crashed immediately. So 2950 @ 1.55v seems at least somewhat stable, i really need to get this thing on a good oc'ing mobo with my new water cooling.

again my stepping is CAB2E 0545 CPBW

opteron 144 CABGE 0536 VPMW STOOkCOOLER


2844mhz@1.45v stable



the board its a asrock 939 dual stata2 but only can get 1,45vcore , when i make the VMODE i come back with more results. But for now i think 2844mz@1.45v stable its amasing .

I'm keeping this one. 148 cabye 0543 fpmw. [IMG][/IMG]

What settings exacty did you change to make the Opteron more stable?

[kemist]

used gskill techs recommended settings for zx ram, some of which you cant edit in the 9nda3+ bios so a64 tweaker helped.

You would be correct about that. Please let us know the bios version you are running. I tried the 2nd beta bios at OCW and could get a little over 320HTT but had a cold boot issue wherein the HTT would not hold and kick back down on restart. Vcore had a nasty habit of resetting as well. Before I sold the Asrock I put the latest official bios on it and the HTT seemed to be capped at 272.

Thats a dirt cheap FX57 rig you have there

Just managed to join the infamous 3gz club on a crappy CAB2E. Week 40, 2005. here we go now:

exactly like mine 146 CAB2E 0540FPMW 3ghz at 1.4v

Tcase max 65c [IMG][/IMG] [IMG][/IMG] 32m @3105 a couple post back.

[GUFY]

coop: Nice clock and what cooling do you use?

[EboNova]

Does my 144 0536 GPMW sucks? Can't get it prime stable over 2700 but it's 100 procent stable in games/windows and superpi @ 2843MHz. I guess my lack of cooling and contact between IHS and core may be a problem. Idle/Load temps are 36-38/55+ with a Thermaltake Venus 12. Have ordered a TT BT which should arrive til the weekend. My V-core is jumping from 1.55 to 1.62 all the time, not sure if my PSU give stable volts (Aspire 520W) Any suggestion how to get this a bit higher?

[mascaras]

hi guys im stupid, my brother just bought a 144 CABGE 056 VPMW and a asorck939 dual sta2 and with stokcooler 2870MHZ@1.45v Pi8MB
