Nice work what was the stepping on this Desert??

I agree, I only posted Dani's 32m speed.

Nice, post results with stepping when you get a chance.:)

Ok this CPU is a little funny, long story but I think it's the ram. right now i am running a 100 minute loop of S&M to see if this sucker really is stable at this speed.

stepping please?

Although it dosn't say it, S&M ran for 2 hours and 15 minutes. It had a box popped up that displayed the statistics, but I accidently rotated to far on my chair and the arm hit the enter key on the bottom right and closed the box, and I don't feel like doing that again for another 2:15 :) The CPU can go higher, but it dosn't play nice with the RAM. This is at 1.6v (1.425 * 113%), BTW

your pix isn't showing up.

Hmm, try clicking this:

Edit now.

Sorry :)

doesn't work

...
ok, um try this:
this is with a different host, if it dosn't work now I cant help you :(

Here is my CAB2E 0546bpmw on water about 45c load:

I forgot to get cpuz shot, but if you want more proof I can re-run

I havent tried anything higher yet so I assume this isn't the limit, my ram is limited me bad though:
3025Mhz

I've done some super pi and 3dmark between 3-3.1 but at 3.005 I am most stable. I have done a 16m at 3.038 but 32m errored on the LAST Loop lol...so Iback her back down.

Opteron 144 CABYE 0536 GPMW
Cooled by a lapped TT BT.

Its also stable at 2930MHz, but I don't have proof for it. Its running Rosetta at those settings for 8 days now, so I guess its stable ;)

Here's my overclock. Note -- not going for best pi times here....just testing cpu. This is on air with a TT Big Typhoon, IHS Removed, AS5 on a DFI Ultra-D using Bios 623-3. :toast: Cpu is a Opteron 148 CABYE 0540 FPBW. Needs 140 divider to run at 3.1....gonna tighten the timings down soon.

140 divider at 3.0-3-3-6-1T, just to see the max. I'll post more if I squeeze anything else out of her. This is on air in my small room in my house (the warmest room in the house to boot). So no outside freezing cold trick here yet. ;)

CPU: Opteron 146 CAB2E 0546FPAW
Cooling: Air on Thermaltake tt112
Mobo: DFI NF4 SLI Expert

PSU: OCZ 520W

Updated 3.1 results - control panel still shows 3.1 ghz.

Dave you should have a requirement for a particular stability test (i.e. 32M or an hour of prime) or the results are not really comparable.

I see most of the peeps posting 32m shots....so I'd say that's probably the baseline for a max single core opteron overclock on whatever cooling you are using. Just be descriptive and state your cooling, cpu type, and type of stability test used. :toast:

This is true, I wouldn't accept the 8m of superPi earlier. I think these are good test to prove it. My goal in making this wasn't to see who is the Best over clocker, but rather have a data base to compare where your cpu is at when you look up the stepping. I was kind of hoping out of good faith people would try to be as honest as possible. I will edit the thread to require more for future posters.
