The Official Opteron 939 Overclocking Thread

[Kesnel]

My reults with a 146 CABNE 0530APMW, on an unmodded Mach II GT.

This chip is stable at 2.9Ghz with 1.48v. The picture is at 2.8Ghz however with the exact same voltages it is stable at 2.9Ghz.

The chip is not stable at 3Ghz even with 1.55v. It will boot and crash in windows.

CABNE 0545 2.9Ghz 1.48v STABLE

[4Qman]

CAB2E 0545

Ok straight away i noticed this chip wasnt as good as the CABNE. It failed to boot at 2.9Ghz with 1.55v.

At the moment i am running prime with it at 2.8Ghz 1.55v. Its been running for the last 30min and is ok.

Ill try lower voltages and then see if its stable at 2.8Ghz.

*EDITED*
STABLE at 2.8Ghz with 1.48v

[before]

This is the highest clock it can acheive with this voltage and cooling.


Opteron 146 CABYE 0540 APMW / Max Stable -> 3118 MHz @ 1.70V / Watercooling -> Full load @ 54°C

i hate you!

nice clocks!

Guys I'm really confused and I have quite a few problems... bear with with me:

1) Neither CPU-Z nor Clockgen can read my memory clock when using the 140 divider... is this a bug? MemTest86 seems to think it's running 1:1 at 280Mhz (it's definately not!) Only 3DM'01 gets it right!
2) Related to this, it seems using the 140 divider automatically disables 1T for me and bandwidtch takes a massive hit (see Sandra). Is this a BIOS bug?
3) Apparently my memory is running at 194Mhz, but how is this possible?? 2800/194 = 14.43 and I thought A64 could only use integers as dividers... shouldn't it be using 2800/14 = 200Mhz?!



Cheers,

Suman

So what did you change that got your clock from 2950 to 3000 MHz?

We only have the "after" A64 shot.

Just loosened some subsidiary timings, twtr, etc. Not sure exactly what did it, though. Two days ago I couldn't run essentially the same settings, even at 2.5-3-3-7. Hell, it wouldn't even boot into Windows at 2.5-3-3-7 at a 2/3 multi, but would at 7/10. Basically, I just played around out of frustration and suddenly it worked -- wish I could tell you more, but there it is. Apparently Opterons are picky as hell about mem timings, not necessarily in normal ways.

With all the optys I have had nothing is a quicker stopper then memory settings. You need some different ram if you have to run those settings.

Yep. Something that did at least 250 would be nice. But looking at those timings (now that I've got a stable config and can -- hopefully -- go back) do you see anything that you'd change?

Only the 14x and 16x models. The higher clocked variants don't seem to be affected.

Only the 14x and 16x models. The higher clocked variants don't seem to be affected.

It says the 14x and 16x were quickly sold out, but when it comes to discontinued cpus it mentions:

Stopped items from AMD for Q4
SDA2500BXBOX 
SDA3100BXBOX 
ADA3000BPBOX 
ADA3200BPBOX 
ADA3500BPBOX

It's time to save a few for the winter

[alpha0ne]

Yep

Unless I am offered an obscene amount of money for my awesome 146 I will be keeping it in the family, same as my P4 1.8GHz @ 2.8GHz default Vcore

You know what? I bet AMD did this to clear out all the failed FX57 cores. They got rid of a bunch of "defective" chips and to us they are gold!

What about the dual cores? But that you say about the single cores may be right!

[Spazilton]

Anyone know what steppings Monarch is putting out for an OEM 170(or 165 or 175). I want to try to get a better clocker than the one I have. Just going to order another combo with a cheap mobo and keep the other processor for an encoder rig.

[stone_cold_Jimi]

UK, today. CPUCity have 146 CACJE 0546 at 125 quid plus tax. One of them is mine.

I did have it on order at 97 plus tax... 25% increase, someone's sussed us out.

[Wiker]

You´re quite welcome TEDY

[TEDY]

Ups yeah hampus is hich nick on MSN

Guys : Wiker is a great guy he helped me getting 4 CABYE's from komplett.se

A true XS fella

And I have another one.........

[dogsx2]

BIG THANKS TO HAMPUS

I never thought you would buy one and then you go and get four. You will have a lot of fun playing with them.

Looks good. Can you bench spi at that speed?

If i have time, work tomorrow + friend's party celebrating his 1st baby...geeze

I can up to 3.28GHz run 1M but the cpu has coldbug and the memory controller doesnt want to play.So the max superpi with TCCD for now is this:



And its not very good,the imc doesnt like cold ........
