The Official Opteron 939 Overclocking Thread

[[ r2 ]]

I can maybe get my hands on a opteron 146 with this stepping:

cabge vpmw

any good?

From DFI Street forums:

1. CABNE 05xx (excluding 0540) / CABYE 0540
2, CABNE 0540 / CABYE 05xx (excluding 0540)
3. CAB2E 05xx
4. CABGE 05xx

But then again its not certain...

Depends on how well you can OC and the individual chip

My CABGE was good for 2980MHz which was excellent but most ppl struggled for more than 2.8Gig with most CABGE steppings

[Wiker]

Chipsetvoltage is maximum 1.8, LDT i havn´t touched, what can i set it on? Dividers is low so the ram is runnin in about 220 mhz can do 250

[ixtapalapaquetl]

Anyone heard of a CABCE 0512? I may have a 150 with that stepping coming...

Hi guys!!
Screenshots of my 146 CABYE 0540 APMW oc's (aircooling big typhoon on a MSI K8N neo2):





MaxTcase tell me 57°C

Whats the wattage of your chip in maxTcase?
I got mine on 2.9ghz @ 1.5V(cpu-z) stable for now.Going to try loosen up the ramtimings.
What is your max async latency and read preamble

[culex44]

MaxTcase gives me 44.1 for the wattage.
My max async latency and read preamble are 8ns and 7ns respectively in my bios (1C3 TCCD modd by sideeffect)

[Pt1t]

Opteron 146 CABYE 0540 FPBW gives an high wattage !

[ianocean]

Any feedback about CAB2E 0545 MPMW please-i might get one few days later?

[187(V)URD@]

MaxTcase gives me 44.1 for the wattage.
My max async latency and read preamble are 8ns and 7ns respectively in my bios (1C3 TCCD modd by sideeffect)

So i got the same stepping as you and maxTcase so I should get the same results as you, but WC setup is borked atm. Need to fix or buy some new things.
Did you write down the full cpu code down, if you do , plz post it.

@troman, check sig. Have it on 9 & 7 ns.

[culex44]

I don't remember the full cpu code but batch was 0338 I think. I'll post it when I'll get my DFI and so reinstall my cpu.

148 CABYE0543 FPMW

only been playing with it for a couple of days .....think i can push it further

i notice these opterons are very sensitive to mem timings especially RP,TREF & Drive strength taking me ahwile to get it nailed

[trans am]

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

do some beers too!

Nice chip

Can you pass 32Mb run on that vcore?

Any suggestions for those of us still in the trenches?? What do these opties seem to like for RP, TREF and Drive Strength??

[smartasien]

awww wat. u can get it 3 on stock vcore?! lucky. mines can only get to 2.8 b4 i needa up it by .25. BAH!!!!

FWIW mine like tref of 3.9us 200 or 166 DS of 5/1 and preamble of 6/6.5

this is on some GSkill LE TCCD's 431

as soon as i throw my Ballistix back in it will be back to the drawing board

Nice trans am!

what cooling?
Im assuming using DFI board?

[Primoz78]

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...)...

Primoz

still playin with sweet spots. so far so good...
this is air cooled using As5 and Hyper6 with 2 fans push and pull. temps load are around 36c

trans am - is that BH-5 your running with your opteron? UTT? BH-6.. its certainly not tccd @ 2-2-2 250mhz

On Friday I got a cabye 0543 fpmw.

Hows the 148 from ZZF doing?

[UTF Nightmare]

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

[5days]

oh my that owns
