The Official Opteron 939 Overclocking Thread

From every post I have seen, 06 chips appear to be going another 100mhz further than the initial rush on the 144-148's of last fall.

Futuremark doesn't say anything about stability, i was able to run 3dmark01 at 3.1 Ghz on the stock heatsink with one of my 146s, although it could barely prime at 3 Ghz cuz of heat.

thats the reason I said bench stabile. still testing, its game and prime stable @ 2950 mhz @ 1.52v with air cooling.

Ok, got myself an Opteron 146 CACJE and wasnt hoping to achieve more than 2.7-2.8 outa this chip, from what i've seen posted here.

First attempt:

146 CACJE @ 2700.88 MHz / Air Cooled / Prime Stable
Mutliplier = x10
HTT = 270
Voltage @ 1.5 BIOS (Burning it in, might be possible to lower it)
CPU Temp = 31-33c IDLE
FSB = 270
RAM = 180

Update: Dropped CPU Voltage to 1.475 and upped HTT to 290

Currently running:

146 CACJE @ 2920.88 MHz / Air Cooled / Prime Stable
Mutliplier = x10
HTT = 290
Voltage @ 1.475 BIOS (Lowered from 1.5v)
CPU Temp = 33-34c IDLE / 40c Full Load
FSB = 292
RAM = 194

Seems like i have room to hit the magic 3ghz mark and possibly more :woot: Seems like 2006 is a good year ;)

P.S. New to the overclocking scene too, not bad for a first try eh? :)

Well i thought i had killed my 146 when i removed the IHS turns out it's alive and kicking. I mounted my watercooling on the naked core and OMFG is it flying, right now i'm priming at 3.15 Ghz with 1.50v, and the room is warm...

Just did this

Definitely one of the best 146s i've seen. If you've got a better 146 on normal watercooling i want to see it!

Is that a typo or is AMD labeling chips with april date? :D

@overcrash: Now you need a hole in the window so you can close it on the cool winter days ;)

No 0604 is 4th week of 06 not 4th month.

What do you do when it rains?? :)

He holds an umbrella above it then :p: :toast:

0604 means Year 2006 and Week 4.

seems my CPU can handle 3.1 Ghz with 1.45v no problems :)

boxed cooling ?:eek:
amazing:slobber:

plz post your stepping :)

Boxed cooling? Holy hell no, boxed cooling this thing loaded at like 60c with these volts. This is IHS removed and watercooling!

What stepping? What other than CABQE 0547GPMW! :)

lol:clap:
nice:banana:
i have a CABQE 0547 GPAW
another guy, with the same cpu, was able to hit 2.8ghz @ 1.45vCore, with arctic freezer pro...
mine can hit till 3.2ghz, @ 1.6vCore right now (no decent cooling)

when my neo2-bios is updated (waiting for a winnie cpu, or nc, or clawhammer), i will post my results :)

problem : it's nforce3ultra (no nforce4)... and i read, nforce3 limits oc's :( (i even thought you wrote the article :D)

lol, i prefer plug the chiller :D

i've tested today, -24°C to liquide :

cant test superPI, my 2k3 was dead :slapass:

and stability test :D

just for testing before sold it :banana:

Hmm yeah, I don't know what I was thinking. My 165 is 0551 :slap: :slap: :slap: Lack of coffe this morning if you ask me :D

I found what you said ;)

Cooling is another big factor, but it's pretty obvious. Motherboard is much more important than most people realize. Motherboards like the MSI K8N Neo1 and Neo2 hold back overclocks. I should know, i've owned both. If you are REALLY and truly interested in overclocking, i seriously advise you to consider the DFI NF4 Ultra-D and nothing else.

--> Is it that bad ? :(

It just means DFIs clock best ;)

You can push it to the limit, when you're using a DFI motherboard, thats a fact:)
Would my MSI Neo2 hold me back for about 100mhz(or more) ?
(in comparison to an DFI motherboard, with nforce4 chipset)
or is the difference in clock-speed rather small ? (at same vcore etc...)

Other mobos hit HTT limits, my Neo2 Platinum didn't work past 275 HTT, i thought it was a bad CPU, nope just a crappy motherboard. Also this is kinda OT next time you have a question like that use PMs...

@Absolute 0, Glad to see you got your water going, those chips were ready for it.
@overcrash86, awesome chip. Cool 'liquid' setup. I use similar with vc only not as extreme.
Just did this testing Di tubes...:D

and I can't resist, I had some left over last night and used it for this,

Jesus coop, 32M at 3.57, beautiful. That DICE really hits the spot.

agreed, there is a sweet spot in there, temp wise. I have to run Systool to monitor temps. Like that prime? lol

well, I got my old CABYE 0540 FPAW:

http://img506.imageshack.us/img506/5...e0135ed.th.jpg
This is on air, IHS still on ;)
(this was before I even bothered with prime)

and a sick low volts:

I have to sell this gem now, customs ripped me off big time on that 170'er...:(
..have to sell on Ebay though, can't let it go to cheaply..

3.1 on air is nice, but 32M doesn't speak as much as Prime, i can run a 32M over 50 Mhz past where prime fails. The main reason is that Prime loads me 2-3c higher than SP32M. Still a very nice chip though - especially for air and IHS still on!!
