The Official Opteron 939 Overclocking Thread

**dnottis** · 12-16-2005, 06:53 PM

Rollin' the dice one last time..Newegg.com retail Opteron 148.

Currently Priming and OCCTing (talk about beating on a CPU) at the same time 3000 Mhz @ 1.5v. Using Aquagate Mini R120 with Thermaltake fan.

Will post back later.

You got the same thing as me and testing the same clock with the same Voltage. Also how accurate is OCCT for stability?

**dnottis** · 12-16-2005, 07:09 PM

OCCT is pretty good - nothing beats a few hours of Prime - buts its good if it passes. Mine is a hot running chip 44-45 load. My 146 @ 2920 was 39 load and my 0542FPMW 148 was load of like 37. Its stable so far so who cares!!

The cooler is cool to touch anyways...
idle is like 32, mine have been 26- 28 so the sensor reads a few degress hotter I think.

**ugp** · 12-16-2005, 08:07 PM

I need more FSB out of my Memory...I am trying to get 273FSB @ 2.5-3-3-7 and that should give me some good scores in 3DMark. Just not sure if the Opty will handle it or not...

**dnottis** · 12-16-2005, 08:42 PM

Priming while OCCTing - been priming a few hours now.

**ugp** · 12-16-2005, 08:43 PM

Do you have a divider being used on your RAM?

I am trying to find the perfect Combo but I can't seem to...

The odd thing is, i can run 2980mhz @ 1.54v through SuperPi 1M, and get a screenshot of 3080mhz @ 1.58v, but i can't prime for more then half an hour on 2800mhz @ 1.52v.
It just seems odd that there is such a large difference between "benchable" clocks and 100% primeable clocks. Heat shouldn't be an issue as i was previously running a 3200+ @ 1.65v, 2600mhz prime stable (10hr+) on the same setup. I've reseated the HSF (xp-120) twice, with no better results, or no worse for that matter.

So far i've done about 20hours of CPUBurnK7 (2 overnight sessions, 10 hours) to try and burn it in, but it doesn't seem to be doing much.

Ideas?

seemed to have got it Prime95 stable @ 2800 with... 1.55v

2860mhz, 1.45v = SuperPI 32M pass
2800mhz, 1.45v = Prime Large or Small FFT fail <1minute.
wtf?

Going to give it a burn for a few days on 1.55v, 2800mhz and see how it goes...

Edit

**ugp** · 12-16-2005, 10:26 PM

I dont get it...I can OCCT Stable but Prime Fails in 10 seconds...

**dnottis** · 12-16-2005, 10:35 PM

I think Im in love!!!

X1800XT PE (new bios) and 148 @ 3.1 Ghz.

Next week maybe more with modded Mach II and BH-5.

nice yankee, but at telenet i finally beat you in superpi, i had 27.062

not that impressive, but you were my goal, anywayz good luck with the mach next week, i hope you dont have coldbug

My Opteron 148 (CABYE 0540FPBW) on AIR

**elh4jj4j** · 12-17-2005, 07:38 AM

Watercooled 0543FPMW

**ManagHead** · 12-17-2005, 07:41 AM

Nice chips you got there! I received my 148 today, CAB2E 0545 MBMW (I think it was). Can run pi on 2,8 with 1,39V. Haven't tested it so much yet.. But I's not as good as they over here I think..

**SET** · 12-17-2005, 07:46 AM

to my Opty 146 doesn't like the 10X multi.

Only 9X

**Pyr0** · 12-17-2005, 08:03 AM

finally managed to get my 146 prime stable at 3050mhz with 1.623v

it ran for over 25 hours before i stopped it

i put 1.7v on it for a laugh, and ran at 3100MHz, it passed 32m super pi

Yup - thats definitely stable!!

Nice job!

**Pyr0** · 12-17-2005, 08:13 AM

thanks,
it's just sitting on my desk now begging me to buy another motherboard so i can use it again, lol

i'm thinking about practicing cutting the ihs off it before i try with my dual core

**dnottis** · 12-17-2005, 10:19 AM

0543 FPMW from Newegg. Pushing it further now using Prime as gauge for stability.

What RAM are you using with your Opty?

**overcrash86** · 12-17-2005, 10:49 AM

just update of my WR Opteron 144 :

DAMN PEOPLE! That is insane...I want some of that clockage right there! LoL

lol

just for fun, i'm testing for stability, but isn't too good, it's a bencher CPU

at this time OCCT run at 3303Mhz 1.472v for 5min...

**laydback** · 12-17-2005, 03:03 PM

Got 2 of these, only tried one so far. Gonna start priming right now.
