The Official Opteron 939 Overclocking Thread

[RafaDel]

Can anyone fill me in on what seems to be the *best* 2x512 ram solution for this processor on a DFI NF4-Ultra?

Thanks....I was able to hit 3ghz on my crappy ram with a MAJOR div unstable, so I'm thinking it's time to upgrade my ram!

I would go for Mushkin Redlines XP4000

[gundamit]

looks like the 148 CABYE isn't too bad either......I'll be happy to get prime stable at 3.30Ghz for 24/7

Gundamit, did you removed the IHS or is it still on?

Still on. It might not make contact with the evap head and if I remove IHS. Also I might end up selling it - some buyers might not like it already removed.

i think my 1M time was slightly faster too with this setting

That's a pretty good time there d22. Is that on wc?

That TIM job does kind of suck. It looks like it maybe had some air pockets unless those voids were left on the core.

As for the infinity tweaks I don't have an infinity or an opti but I'm thinking you might be able to do all the mem tweaks with a64 tweaker.

If the special vids on that board are available you should print the voltage table from the guide and try different variants since some vids of equivalent voltage are more stable than others.

Systool and speedfan works on some gigabytes which also have the IT8712F which is supposed to be whats on the infinity. http://www.dfi-street.com/forum/atta...achmentid=2477

Not to get OT but post how it goes as I'm curious if the infinity can be made to work more or less as well as the lanparty.

I put a 146 in an old neo2 rig they use in the house. When your used to a dfi with all the memory tweaks and then you only have the basic 4, it really makes a big difference in how much of a stable oc you can get. I didn't want to mess around with the TT BT or the hyper6 so I put a smartcat fan on an old silent boost cooler. If I remember right, the MSI core center did not read temps right. It shows 52c idle but I can feel all around it and it doesn't feel hot at all. Anyway, here's a ss with zero memory tweaks (that's why the time stinks). I could run windows at 3000 1:1 but pi wouldn't finish.

Just realised I had ram on 2t.

I've had both boards and the lanparty is a lot better board for the same price. Why would you want to pay the same money and then have to use a bunch of software to try to get where the other mb is already? You also get all the round cables with the ultra, infinity only has 1 ribbon and floppy ribbon. Smart guard is less and all bio options including dividers are less. Dividers and memory setting are the most important on a 64.

It's easy to be curious if something can be made to work if your not the one trying to make it work.

thanks....yeah i'm on water................BUT I have some problems with 32M times.........not as bad as AFI but certainly pissing me off.............has anyone else compared their 32M times against their old SD or Venice figures here

1M times are unbelievably fast BUT 8M and 32M times are house..........

Abit AN8 Ultra with Venice at 2.9Ghz RAM on 263MHz 2.5-3-3-6 (GSkill TCCD)
32M SuperPI 25m 50sec



DFI SLI-D with Opteron at 2.9Ghz RAM on 290MHz 2.5-4-3-7 (GSkill TCCD)
32M SuperPI 26m 00sec

[dinos22]

Here is the first Opteron 175 with some OCing action from a fellow OCAU member

some more results

2600mhz @ 1.39v 32m Super Pi stable


just for a laugh decided to see how low could get vcore

1.2v @ stock speed 32m Super Pi stable, 0.11v below stock


boots at 1.15v but is not stable.

2700mhz @ 1.46v 32m Super Pi stable

load temps around 46c
2750mhz @ 1.54v 32m Super Pi stable

load temps are around 50C

finally cracked the 30min barrier for both cores lol

yeah one core is happy with 1.46 @ 2750 mhz, the other needs the extra volts to be stable.

I know how bad it sucks to try to make stuff work, which is why I offered what I did, but I didn't tell him to buy it so he could be my guinea pig. He already bought it and I just offered him some ideas on how to do stuff that he asked for.

Not sure about a "bunch of software" either since everybody loads a64tweaker and the only difference between smartguardian and speedfan or systool is it doesn't come on the cd in the box. Even guys with ut's have to use a custom config to make mbm5 work. Who oc's that doesn't have to load 8 million bechmarks and tweak tools anyway?

There's also about $50 difference between an sli-dr and an sli infinity so they're not the same price. The ultras are the same but then you have to mod the board which is probably better but I've never modded one and I hear they are putting epoxy over the parts you have to connect now to make it harder. Also nvidia is trying to make drivers to fork up the modded boards so if they pull it off the cheap sli goes down the drain.

If he can't use the vid's then that would kind of suck but if he can get his mem with a64tweaker I don't see how he's hurt too bad.

Got my 148 CABNE 0528 the other day and I'm still playing around with it but I got this so far.

Awesome. Where did you buy it ?

[dinos22]

here is some more OCing by that Opteron 175..........it's looking good

2800mhz @ 1.60v 32m Super Pi stable


2850mhz @ 1.65v 32m Super Pi stable

load temps are around 58c

needing to increase the vcore more now to get both cores stable. not really happy with the high temps so wont be pushing it any further.
guess I will have to be happy with the performance of dual fx-57s

heh maybe this chip could hit 3ghz on vapo or water.


those results on XS look familiar dont they dinos?

[Vapor]

What kind of aircooling is he using??

[dinos22]

TT Big Typhoon

[F|apDro|`]

anybody heard of this stepping ?

CABYE 0535 XPMW

If so tell me some results

[Vapor]

Somewhere between CABGEs and CAGNEs

[sponge bob]

0536 cabye cpgw
what about that?

[furyfax]

Isn't there a list of OC result with stepping of Opterrons s939 CPU's ?

[Vapor]

No. There are general rules of thumb though: CABGE < CABYE < CABNE. We don't have enough data to make any other statements though.

[uOpt]

Dinos22, do you know what the markings/week on that 175 are?

[skirms_fr]

CABGE SUX yaaaaaaaaaaaahhhhh

[AgentVX]

I'll answer since he's probably gone to bed...it's a CCBWE 0534SPMW.

While I'm waiting for some more seal string I decided to start playing around with the Asrock 939Dual I picked up for $70 from Ewiz. There are a few threads showing this mobo has some potential with a couple volt mods. I thought it might be a good match for the Opteron because they're both cheap and the Opty doesn't really require much voltage. Without a volt mod, the mobo only gives 1.45v.

Dogsx2 also got this budget board and pm'ed me that he was less than pleased with it. After reading a bit more I decided to start by flashing it to a OCWB beta bios #1 that I picked up here.

Like the EVGA mobo I tested, this bios doesn't include a lot of tweaks, but it remembers its bios settings when OC'ing unlike the EVGA. No Clockgen exists AFAIK for this ULI chipset so it had better.

Right now HTT seems limited enough that I'm kicking myself for choosing the 144 (while my 146 just sits) to have first crack at this board. The bios started acting a bit strange around 326HTT so this 144 isn't going to see the same 3ghz it saw on the DFI. I picked out some Twinmos CH UTT and threw a big divider at it. Vdimm selections include "normal" and "high" People with Winbond based memory may want to take a serious look at the vdimm mod.

So here's my start point with this mobo.



At PC3200 speed maintaining 1T doesn't seem to be a problem, although that been a problem reported by some with this board and I expect it'll rear its head soon.

I have no idea how far this board will get. How much should you expect for $70? A mildly OC'ed (1ghz ) stable game platform wouldn't be too much to ask for right?

[el rolio]

uh, i know this may not be right, but im posting it here anyways. since my 146 is on its way, i wanted to just get a record of my outgoing OC. i ran this computer pre WC at 2.5 all year till sept. this is where im at now. at the very least i could learn some things about my mem tweaking, even tho without active cooling it seems 2.6v is my usable voltage limit.
