The Official Opteron 939 Overclocking Thread

Cabne 0540 Bpmw

Ok?*

[Gadflyii]

Update on my 150 CABNE

I got the memory bug worked out with timings, and bios change, and I was able to get running dual channel finally. The HTT on the board is my limiting factor right now.

Here is a quick screen shot taken last night after a few hours of WoW and BF2. The 3dmark was taken at stock speeds (450/1200). It is running prime today while I am at work. I had to push the memory from 2.9v to 3.2v to hold those timings. What is the safe voltage limit on that ram? (OCZ Gold EL 2-2-2-5), I raised to voltage to 1.7 in an attempt to get it stable at 3.5, but it made no diffrence. My HTT just gets unstable, even with the CPU turned down to 1200mhz.

What is the safe voltage limit on that ram? (OCZ Gold EL 2-2-2-5)

Providing you use active cooling 3.5v - 3.6v should be ok for 24/7

Nice OC there dude.

edit:- btw try TWTR 1, TRFC 14 and TRC 7 to get the more speed out of it.

[Gadflyii]

wow that high!

[HermS]

Yup, winbond loves volts, I don't think I've ever run mine below 3.4v

[Gadflyii]

Think it is possible to run it 1:1 @284mhz? @3.4v? I have a big case fan blowing directly on the memory, is that suffeciant cooling?

[HermS]

Think it is possible to run it 1:1 @284mhz? @3.4v?

Extremely highly unlikely even with the most cherry picked sticks ever. At 3.4 you will probably see 250-260 ish. This thread has loads of info on Winbond based RAM, get reading my friend

edit:- You may want to play around with different multis and dividers to get the ram to it's optimal speed.

Hi!

I see that some stores is operating with two different names on theese opterons.

1.Opteron UP "San Diego"
2.Opteron "Venus"

Does this make sence? Can it really be San Diego cores in some of them?

And, do you know any stores which is shiping to Norway? I want a nice Opteron!

They which can be bought today, how do they clock? Any gold chips? (steppings?) I already have a Venice which is doing SuperPi 1M at 3150mhz cooled by single phase change. What can i expect with an Opteron?

[dpajur]

Is anyone using PowerNow with their S939 Opterons?

I'm getting mine next week, finally moving away from Intel, and I thought PowerNow on an OC'ed Opteron would be a great thing..

I leave my PC running 24/7, and there's really no need for it to be running full voltage and full clock if it's just downloading some stuff off the web or checking emails.

I've read on DFI's site that you shouldn't use Cool'n'quiet if you're overclocking, which raised my concerns about PowerNow..

Can this be done?

I thought it only dropped the multiplier (voltage too?).
Can the levels be set?

I'll have a mCubed tbalancer in the box, and it would be really cool to drop all the fans to zero or very very low and have the CPU running at a low clock and low voltage until it's needed to do some actual work (like games or video of course!)

[SPivX]

well, i've tested 1 of 3 Opteron 144's (CABNE 0540BPMW). But man, this thing sucks! I'm currently @ 2520 @ 1.5v. I set the RAM divider to 1/2 and the LDT multi to 3x, so it has to be the CPU. Look at the screenie, this HAS to be the worst clocking Opteron 144 on the planet!



what am i going to do? please help a newbie! thank you very much!

[TEDY]

so i should avoid 0540 CABNE BPMW

[SPivX]

please look at this thread on DFI Street:

http://www.dfi-street.com/forum/showthread.php?t=26642

i found out that the 0540 CABNE BPMW is not the best Opteron 144. In fact, i think it's the worst out there and i'm gonna return it to the shop i bought it from.

[perry_78]

Indeed, these opterons are HOT. My NE 0540 APMW is 46ºC loaded under 1.6 bios set (smart guardian shows 1.56V) and a tripple ice pro with an asetek antarctica.

Bloody hot...

Results:

CABNE 0540 APMW
133785AJ
batch # 700's

Default Vcore
2700mhz 300*9 ram at 133 divider
SP2004 stable
SP32M stable

1.55*1.04 shows as 1.56Vcore

2806mhz 302*9 ram 133 divider
SP2004 stable
SP32M stable

havent tried more, but obviously not the best of CPUs. Getting a 146 from our belgian friend I think, and a mousepot as soon as the next batch is made. Considering my batch number is high 700s I think the results are ok.

What I find interesting, is that I cannot boot up into windows under a variety of settings, but when I clock through Clockgen it's easily stable 2806mhz is as stable as it can get, but 2826mhz with same settings and only slightly higher FSB results in BSODS... Interesting CPU...

Needs a lot more testing, curerntly adjusting eva2000's OCZ VX timings he used in his San Diego thread

[MadMikeSS]

Just got my Opt 146 retail box from Monarch today. Haven't really had much time to fully test it, but it's looking promising so far. It passed superpi 1M and 8M. I still have to prime it to see if it's stable. Keep in mind that I have had winchesters, venices and others that I have never been able to even boot at these speeds. So for me this is a major leap.





It's a start...

I actually lucked out on this one. They are selling for $199 at Monarch now, when I bought it on Monday I managed to get it at $181 plus shipping.

I just ran SuperPi 32M and passed:



Will be running prime later.

[SPivX]

i can get a 148 with the following code:

osa148DAA5bn
cabye 0536gpmw
1304597150259

is this one worth trying? and is the 148 worth the extra bucks over the 146?

[Sumanji]

MadMikeSS:
How come you run TRC at 7? I did a comparison between TRC at 11 and 22, and found no difference whatsoever. Does having it less than 11 help a lot?

Cheers,

Suman

It's not the worse for sure, mine is running at 3ghz+ stable.

Coolling? volt?

Where did you ge it and when?

Honestly, I have my memory running at optimized defaults. For 704 bios that's what trc is. I'll tweak with memory timings later. Right now I am just messing with defaults.

i can get 1 with same stepping , are they good ???

[eR1k]

They are pretty good, 3ghz at 1.65vcore. But if I were you I would get a CABYE 0540 instead.

[xxmartin]

Looks like we're good at 2.9GHz on air. I'm going to keep priming until I get home from work - little burn in can't hurt.



Here's my memory settings:




When I get home this evening, I'll let you know if it primed through the day, then I'll pop the IHS and shoot for 3000+. In the meantime, let me know if you guys want me to try anything else. My students have a Calculus Midterm next week, so I imagine I'm going to have to stay kind of late tutoring... I'll get back to you as soon as I can.

Holy s***! That's the by far best Dual-Core I have ever seen! So far, no Dual-Core ever went on water lower than 1.6V @ 2900 MHz!

And you are doing 2.9 GHz @ 1.44V on air! Go for the 3 GHz with that hot baby. That's and absolutely outstanding chip you've got there.

[Nano2k]

Coolling? volt?

Where did you ge it and when?

Watercooling, IHS removed and 1.648V

From Computermsa.

[NYCTeeN82]

MadMikeSS did you get that stepping by chance, or you asked for it? Did they tell you? WHen did you order that chip?

[perry_78]

I'm going to remove the IHS, 52ºC loaded temps on an asetek block are too much.

CABNE 0540 APMW

stable at 2900mhz @ 1.67Vcore, 1.71 BIOS set.

2950mhz runs SP32M fine, then suddenly BSODS. Something tells me the RAM plays a greater role with the opterons than with the Venices.
