The Official Opteron 939 Overclocking Thread

[bmac11]

I would say CABYE 0540FPBW. If its too much over retail.. I would try from newegg. I just ordered a 150 from them. Hope they have some old stock!

[MaxxxRacer]

my current philosophy on the IHS.. is 100mhz (max) worth the posibility of killing your cpu? is it really? will you be going for a WR with this cpu? No?? then why the 100mhz..

And in my experience I gained 0mhz from popping the IHS and in one case ended up with a cpu that was doa after ihs removal. the other one that gained no mhz died within a few months after ish removal..

so is it really worth it.. no...

thats why my 146 taht does 2.9ghz will be staying with its IHS firmly planted on the core for as long as it shall live.

[HousERaT]

fooling around with different ram and bios I've settled on this for the moment. Info in sig

*KoHaN 69 breaks into Maxxx's house and takes ihs off while Maxxx is asleep*

I have a Opteron 148 CABYE 0536 GPMW, for now this are the results using a xp90c with a noisebloker 92mm( i crap of fan) and a cpu almost without AS5( is finished in the same time that i put on the cpu )




For now the max validation is 3200 @ 1.6v:

http://valid.x86-secret.com/show_oc?id=52601

Next Week this baby goes to negative temps , well my last bench as at 2850 @ 1.39v running PI32MB and i think that run too at 1.37v with the same settings.



With phase change i hope to reach for pic 3600/3700 and using for day 3200/3300.

New Opty 144 stepping - CABNE 0544 EPMW

Anyone have any results for this stepping?

It's a CABNE but the week and letters are relatively unknown.

[dogsx2]

Down to only my 144 for the moment so I thought I'd do a few 3d benches with it.

i'd be surprised if you couldn't hit 3.4 for 24/7 usage under phase


hopefully my 148 cabye 0543 clocks as nicely as yours .....and we survive the cold bug

A small look at my new 148 0540fpbw and epox NF3 mobo. cooled by water with a Maze3 block and no IHS.

Heres my new CABYE 146 0543FPMW

I can actually bench OK with only 1.42Vcore but with such high Vdimm I was worried about frying my chip so upped the Vcore a little





I'll see how high it will go later, its also Prime95 stable @ 3GHz though only tested for two hours

Very nice! Is it also a CABYE?

You had me looking fast. I thought you meant 26.000 not 27 minus .015.

I installed an extra dualrad yesterday. now 45C full stress after 5h of prime.

What a chip!

[NYCTeeN82]

Lets all remember that CPU-Z always shows .04-.05 below what is set in the Bios. Like I did 2950 at stock voltages, but CPU-Z read 1.36.

Same *2920MHz. I hate people who use CPUz as a guide.

So you added a second radiator, dropped 4C and .02v and can still Prime at 3ghz. Now push it a bit more.

New Opty 144 stepping - CABNE 0544 EPMW

Anyone have any results for this stepping?

It's a CABNE but the week and letters are relatively unknown.

He EPMW was earlier one of the best overclockersteppings.
I know an 3700SD who has the Stepping 0508EPMW and it runs 3230Mhz at 1,56VC Primestable. Owner is Stonka on HWLXX.

Here´s a Link to the Thread:

EPMW was earlier one of the best overclockersteppings.

Those letters are nothing but dates and wafer sequence numbers - comparable only within the same date. They have no relevance when comparing procs with different dates.

See last page.

[Rufus7]

Yes you have right nothig is comparable. Only same Productionweek and SN.
And even then is a lucky thing to get an good CPU.
HS is very important for clocking. Best CPUs have almost bad HS´s.
But EPMW where in the Past FX Steppings and APMW and GPMW and MPMW etc.

[dogsx2]

Same *2920MHz. I hate people who use CPUz as a guide.

You mean you hate THAT people use CPUz as a guide, right?

[Rufus7]

You can even use CBI or Everest if that´s your choice. All the same.

I tested my opteron under 3dmark benchmark today.
Aircooling xp90c + noiseblocker SE2 for cpu
Stock cooling and voltage for my gfx card. (gto²)
