The Official Opteron 939 Overclocking Thread

So you are without IHS on the Freezer 64 pro? sounds interesting.. perhabs I should try that. but I don't really trust my temps that much because the cooler is quite cool and I got a nice airflow after my opinion..

/Grau

Yes it's useless IMO. If you have a copper base like the freezer has it will work great if you have it installed properly. Mine is facing up towards exhaust fans, one on top of case and at back, plus the psu is sucking it out too. It doesn't clip too tight either on my DFI when you take the IHS off, so no worries about crushing the core. I cut my damn fingers trying to cut it off though heh. Had to use a thin shaving razor but once i cut through it was easy to wiggle off with my finger.

Thx you very much for that information, how did you install it again afterwards? with the clips also? and there is still good contact? i would very much like a picture of your setup, if thats possible

Sorry I'm not able to do pics right now but i didn't modify the clips in any way. On the DFI board it either faces up or down based on the location of the retaining clip on the mobo. By unscrewing the clip on the heatsink its possible to turn it i believe but in my case it wasn't necessary. It clips down with about half the pressure it took with the IHS on, which is still enough. My temps are 38c load so it must be good contact, using AS5 with a thin layer applied with a credit card type plastic on the core.

Hey guys, I've been busy, but finally got around to tweaking this thing. I FINALLY got it to pass 32m at 3.005 ghz, my ram blows worst utt ever, it'll seem stable at 245 mhz then the next day produces errors at 225 I don't get it. anyways here is my screenie!

[nfm]

actually i was on 23th pass in 32m calc at 3102.5Mhz (I oc by 50mhz) but my ram in conjuction with on-die mem controller crapped out. this cpu is going for sale

ihs off, cab2e 0546fpaw, cold bugged

[mascaras]

well , steel in testes with opty 148 and this patriot TCCD , but they rocks like hell , opty 148 @3090Mhz@1.50v//TCCD@309MHz cl2,5-4-3-7 1T @2.73v

Hey guys. Just a short question. I'm selling my 3700+ and buying me an 146 opty. Wich stepping should i take; CABYE 0543 FPMW or CABYE 0540 FPBW??

Thanks in advance

[shuRe]

do a search within the opteron overclocking thread (here) on both steppings and find out.

You should take the 0540FPBW.
FPBW are the better clockers.

Here´s a List with Steppings and Results.

[Shark-357]

Go with CABYE 0540 FPBW

[no_n|ck]

Hi, thanks for replys guys. I did a fast search thru this thread and found some informations;

0540 FPBW is good clocker but needs more volts than 0543 FPMW. FPBW is also running very hot, as i noticed from this thread. On the other side i found only two guys here that are having 0543 FPMW (alphaone is one) and so i can't be sure if i will be as lucky as them. Hmm, ...

[dogsx2]

I have a CABYE 148 0540 FPBW and it's a great clocker. Go with the FPBW.



Look for it in fs soon.

I just bought a 146 opty CABYE 0540 FPBW. What clocks can i achive with high end air cooling (Zalman CPNS9500)? Can't wait to get my hands on that chip!

[Rufus7]

Between 2,9-3,1Gig on Aircooling, but not with an Zalman.
Youhave to choose en Thermaltake Sonic Tower! And two or three 120 Fans.

Hey a ThermalTake Big Typhoon and you can.

[no_n|ck]

I already got zalman 9500 wich i think is comparable with TT BT. If i will do an upgrade with cooling i will take TT BigWater system - it looks nice for that price.

a unlocked 144????? cool

[melt5]

This is mine, still need more burn-in.....CABYE 0540 FPBM
Running with DIF Sli-Dr and thermalright XP 120

[PI7ER]

a unlocked 144????? cool

YES
CAB2E 0545CPAW

[Discipl3]

how is that possible? is it a manufacturer sample?

[AP0ll0UK]

What do rate to to my overclocking results. Be gentle as its my first but any feedback would be appreciated. Memory is currently running on a 09/10 divider in order to get it to the 2.8 mark, it would be nice to try and get it harder without loosing memory bandwith.

The Screenshot is <a href="http://www.ap0ll0uk.pwp.blueyonder.co.uk/images/2794.jpg">Here</a> as it was a little bit too big to attach.

Nice start and a nice stepping you got there. A little more vcore should get you 3Ghz on air.

[AP0ll0UK]

Thanks, I see you've got your nicely chilled It's nice to know that my oc is heading in the right direction. I don't really know that much about mem timings and took some advice a few months ago (which was the last opportunity I had to dabble with the overclocking) which has brought the mem timings to where they are now. I have them running at 1T but was told that my ram should run at 2T but I also read that your system performance decreases when ram runs at 2T in conjunction with AMD 64's.

What kind of increments do you think I should push the fsb and voltage up and what are the max volts I can give the Opteron?

One other question, what graphics card did you have before the X1800XT and what kind of games do you play on it?

[Viss]

No need for 2T. I do not like mine to go over 55 deg C load on air. Up to 1.65 or 1.7v just to have a look what it does should be fine, but i doubt you need that high for 3Ghz. Just go up in small steps and see how it scales while keeping eye on temps. Get mem on 150 divider to exclude mem while looking for max cpu.

Previous card was X850 and the only games i play are some older FPS.
