Cooling:
Water cooling
thank you my firend :toast:
i think i can have 2400MHz but it will be hard for the chipset :slobber:

:stick: :banana4:
I can only imagine the ECC in the ram is helping it be stable? i don't know much about ecc or how it works so im talking out of my butt hehe.
I had a 240 a new one it overclocked well using standard Heat sink I got it to 2 gihz. I had a 246 but I couldn't get it over 2.3 gihz stable for some reason. I had some nice Corsair 3200LL ECC reg ram it flew I got like 6 gig mem through put.
Nice oc.
Maybe you can get Sub ZeroCooling or Window opened ;) ?
I think they Lock the BIOS on purpose as soon as the board detects the Opteron.. I had a Sk8N 1.03 with initial BIOS release when I put a 146 Opteron in it was detected as an engineering Sample and the Voltage control got Unlocked. Unfortunatly the BIOS sucked and could OC as much as I could with new BIOS'. I think if you could fool BIOS in reading Opteron ID it could unlock the Voltage controls. The New 90nm Opteron are going to kick ass at ocing because of 55 watt heat disapation.
Oh I found the Sk8V was much better for OCing for some reason. :)
Generally it corrects single-bit errors server's running massive up-time experience, and minimizes system crashes/data loss as as result.Quote:

i'm sure i can go higher with more voltage like 1.75v :confused: :stick:
Yes i can go higher with 1.75v :D
http://img67.exs.cx/img67/525/screenmax2xm.jpg
screen max but it's not the cpu i think :stick:
is it 32MB SuperPI stable? or Prime95 stable?
And.............*drool*
I think it's the world record for A64 in percent ?
Good work my friend ;)
+75% exactly :toast:
Nobody can compete :slobber:

All my results are on single channel !!!! :banana:
Thanks to my friend misteroadster :toast:
:toast:
I've never seen anyone overclock with an Opteron like that... :slobber:
With some nice TCCD chips and a 5:4 divider your Super PI results should get even better. :)
2449 / 1400 = 1.75Quote:

Isn't that an overclock of 75%? :confused:
1400x(75/100)=1050 you're right sorry , i've done a mistake. ;)
it's a little hard to screen i think :D

PI 32MB with single channel:
http://img44.exs.cx/img44/5192/superpi32mo8007jd.jpg
currently running at 2350MHz
i can't use TCCD chip because this motherboard works only with ECC REG ram ;)Quote:

For the love of god, give your ram some TRAS...your choking your ram and not allowing it to perform lol. Give it a tras of 5 or 6 and I guarantee that you'll see better bandwidth.
it's better with TRAS at 0 in many benches ;)
I'm honestly surprised that that board can handle that kind of HTT. What's the PCI bus running at?
the Sk8N has pci/agp locked as all nforce3 M/B just boot with 201 FSB.
It can handle 350 Fsb rock with LDT 2X.
tonight testing with 4 x 512Mo PC2700 ECC REG Infineon :D
to hit 34 sec Spi 1MB :D
very nice result :toast:Quote:

FX51
SK8N (bone dry stock)
OCZ 3200EL 2x256MB ECC Reg on that run.
Also got some OCZ 3500EL 2x256MB ECC Reg to play with too :)
hey long time no see!!!
anyway..good job my friend!!! :D
I like this Opteron more and more, especially they're very cheap to get on ebay...
Nice work man...350FSB holy :banana:

with my 4x512MB PC2700 ECC REG infeneon it's easy to have 34sec for PI 1MB :)
but 33sec is harder to have :D
new toy (FX-51) is coming in a few days :D
damm you like those 940 chips dont you? what mb you running ? i always wanted to check out a operton amd your stroke of good fun only makes me wanna do more! nice job man. awsome ocs!!!
peace perc,
I'm running on an ASUS SK8N motherboard ;), and i want to mod it (vdd and vddr) to go higher because i think the chip limites me, i'will have 100% oc with 140 chip maybe :D
i'm waiting for my FX-51 and 2*256mo PC3500 ECC REG OCZ (cas2325)
Thanks.
FDH
Good job man , Opteron roxx :D
i can do better with volt mod ;)
nice,
i aslo get 35 sec on my northwood 3.2@4ghz
i have 34sec with dual channel at 2400MHz :)
my toy without HS :D
http://img70.echo.cx/img70/2706/ihsoff6409mg.jpg
new test in xtrem water coming soon :)
ECC is off I'm sure...no reason to turn in on (via BIOS). Registered memory has electrical points that are registered (duh) so the master ECC (error correction) can stop data flow at specific points on the ICs.Quote:

Socket 940 power baby.
Wow very impressive oc. 75%!!
I love the goal of going for 100% overclock.
sweet oc man :toast:
good to see you back at xs :D
1.4@2.45 :banana: not the percentage oc record, and not the highest mhz gain oc on an a64, but def for an opteron! :D
Yeah that is a friggin awesome OC. Is there a dual opteron board that can OC? If so, I may have to do a little shopping. :D
no it's an ASUS SK8N (NF3) board :)
saaya : i can do better :D,this cpu seems really love vcore and i need time to do vmods (vcore and vdd)
next i will try with a better cooling :D
Haha... I love seeing older / unloved chips getting OC'd. Awesome results man. :)
cant wait to see you pushing it man! :D
if you need help with the mods shoot me apm :)
o m g... Nice oc you've got there on that opteron.
get that under some LN2 or someone's cascade and get it up to 3ghz+, then I will be amazed. Good job so far, but I think 3ghz is possible.
hey, i have a sk8n too. have a naked opteron 140 and fx-51 too! i love 940! i have 2 gigs kingston value ram reg ecc pc3200. need hsf, psu, hdd, and os and ill be set.
Jeeze Id like to know how these would overclock on a dual cpu setup.
Dual cpu motherboard are not as good as SK8N or SK8V :(
I don't know if my cpu or SK8N is dead :( but it can't boot :confused:

btw gotmy fx-51 doin 2.5ghz. dunno if its stable tho, i get errors on 32m superpi at stock, i think its the psu.
ppl, thanks for sharing all the data! i am completely new to overclocking - never tried before. any chance you could suggest a couple of safe and resonable setting options for opteron 140 / asus SK8V?
asus sk8v
opteron 140, OSA140CEP5AK
1 GB OCZ Enhanced Latency (2 x 512MB) PC 3200 ECC
ZALMAN ZM400B-APS ATX 400W Power Supply
160GB Hitachi, Mirror RAID on Promise SATA

I always loved Opterons but that OC is just insane!! :slobber:
any1 know what bios he was using on the sk8n? im trying to oc my 140 but theres no vcore options on mine and htt doesnt go over 300. was he using clockgen?
