What is the best Opteron Overclock on stock volts. Mainly talking about 146's here but any Socket 939 Opteron should help. :toast:
The reason I ask is because I have an Opteron that is PrimeStable (40 Minutes no errors) at 2920MHz on stock volts. I will try for SuperPi 32M later, but right now I just want to know what is the best 146 overclock on stock Vcore. :D
EDIT: This is on Zalman CNPS7000Cu AIR! :eek:
I don't know the answer to your question, but your's is a great chip indeed ;)
I'm receiving a 146 soon, i hope it's that good =/
Yeah me too! Good Luck.
But I had some really bad luck with my Venice. LBBLE 0516 FPAW. Didnt even do 2.7GHz on 1.7V, and barely managed 2.6GHz on 1.6V. What a shocker of a chip. But this has renewed my faith is AMD. :D
My Opteron 144 is a real shocker, only does about 2450mhz on stock volts. It's a CABNE as well, i thought they all did like 2700mhz with stock.
5days | Opteron 146 | CAB2E 0540FPMW | 2920MHz | 292x10 | 1.4V | DFI NF4 Ultra-D | Zalman CNPS7000Cu | SuperPi32M
w00t!
This is great! :D
EDIT: This must have been an FX-convert. :woot:
1.4Vcore is default?
Here is my with TT BigTyphoon and DFI nF4 SLi-D, BIOS 6.23-2
Ps. now @ 3072MHz +18h StressPrime 1.45V on air (ambient +23ºC)
http://koti.mbnet.fi/dani69/DFI%20nF...4Vcore_AIR.gif
default volts on a dfi board will show as 1.36V in cpu-z, youre putting 1.45V through that
Yeah I meant default Vcore as set in BIOS, not read by CPUz. I dont trust CPUz as it is always a fair bit off for me. :)
What the the complete steppings on this? **** CABNE **** ?Quote:

Ohh well , its still an fx57 at 220 USD , so I dont care ;) .
mine does ~2875-2925mhz with stock voltage, depending on room temp. CABNE 0530 ;)
though, there are some opterons with 1.35v at stock, i've seen one :D
Processor: AMD Opteron 144 (San Diego)
CPU Speed: 2826.71 (314.08 x 9.0)
Revision: SH8-E4
Platform: Socket 939
Startup VCore: 1.350v
Maximum Case Temperature = 65C
TDP: 67.0 Watts
:cool:
Air? :p:
hmm, i guess i don't have cooling in my sig anymore, oh well :p:
water, lidless 146.
Mine runs quite cool actually, about 33c on my watercooling with 1.5v 2610mhz. My X2 3800+ does 37c with similar volts and mhz.Quote:

Stepping is CABNE 0540 BPMW.

this cpu don´t Keeps higher clocks ( 3ghz) increasing the vcore. Idon´t understand.
sorry my english
Here is another one with good Operon...stock vcore. http://forum.sweclockers.com/showthr...hreadid=525754
A quick run with this one ...

that looks like 1.425v in the bios though ;)Quote:

still better than my old 144 CABYE 0536 m8 :toast: couldnt complete SP1M at 250x9 (2.25Ghz) at stock voltage :banana: :banana: :banana: did 2.95 with 1.63v though :DQuote:

Well, I think most/all of these "default" vcores are anything but. 1.4v under load isn't default. 1.35 is sometimes default depending on chip, and under load you'd be lucky to have 1.35v going through the chip on any mobo even if your opty's default vcore is the higher 1.4v.
Anyway, since I can't use anything but default on my ASRock I'll give you a real oc on default volts. Dual Core Opty 170 does 2.5Ghz (10x250) easily and that's on Scythe Ninja with a sub 1000 rpm fan blowing on it and a sub 1000 rpm fan exhausting hot air from the system. Haven't tried higher yet.
I dont understand what your trying to say so heres a banana: :bananal:
its pretty clear that the title says "Stock Volts". that means no 1.36 (1.40 in bios) and up. mine is priming now @ 2.7ghz 1.31v (set to auto in bios), ill post a screenshot in the morning.
LOL .. Ok .. Vapo it is so temps were helping before a Vcore bump. Other are doing some great work there ... later ;)
2.7ghz @ 1.312v (set to auto in bios)

Just be carefull not to run stock vcore with high vmem (>3.1V)... :)
I get it now. But your wrong. Stock Vcore for an Opteron's 144-154 is anywhere from 1.35 to 1.40V.Quote:

Could you explain why? I did so and I think there was nothing wrong with it ..Quote:

Not bad for a $189 shipped chippy :)
(that is for short testing only, no 36 hours prime 95 yet)
no not bad at all. i'm happy with 2.7ghz @ 1.31v on my dual core. when i get a motherboard that doesnt overvolt the 110w opteron i will start turning up the voltage a little.
