The KACAE 0601WPAW may be OK, but nothing spectacular. LBBWE 0551VPMW, not sure about that one - but maybe worth a try. The rest PROBABLY suck

[stunned_guy]

Same opinion like knut, all will suck....but i think the 3500+ winchester cbbid 0532 fpmw could be the best of all. all processors with all the letters except M and A in the 3rd position will suck.

[WiK1d]

Okay cool, I googled the steppings, but couldn't really find any results. So you guys think they are pretty bad?

Any general rule of thumb for identifying a decent stepping? And how to assume if it will be cold bugged or not.

[stunned_guy]

cold bug search will be difficult but there will be one thing that you have to know: all steppings with an number on the 4th place have a cold bug in 99%. so like LCB9E or KAB1E and so on...

what kind of processors do you want to overclock ? The old newcastle or winchester cores or the newer san diego ? steppings like GPMW, GPAW, APMW, BPMW and FPMW are in most cases the best.

All of the cpus above arent good enough. search for another ones.

Any BB, B1, B2, B3, B9, BQ, CA or CJ will be coldbugged. There are some other coldbugged chips as well, but they're quite rare so don't bother about them

The week number usually gives you an idea if it MAY have some potential or not. It's hard to remember all of them, but 0602, 0614, 0626 are some of the better ones.

The LEAST coldbugged stepping you can find would be BF I think. BY, BN and BH, BW and BL (these vary a bit, though) are also very dryice/phase friendly.

[stunned_guy]

Today 1x FX-60 and 1x X2 4600+ Toledo are on way to me attention knut

yesterday i tested my first opteron 180 LCB9E 0651 RPMW --> B9 with horrible cold bug....could do benching with +20c only....so no high validtion was made: 3442 mhz

Okay, these double digits are the 3rd and 4th characters of the stepping right?

Thanks for the info guys, I'll keep an eye out then.

[stunned_guy]

yes so it is good luck to the search.

[WiK1d]

Thanks, but now according to what you guys just told me, this one might be good? CCBWE 0607VPMW, or is the date crap?

Oh and another question, is it possible to figure out if it's an E4 or E6 via the stepping?

[stunned_guy]

CCBWE is an E6 and its not good Its one of the older steppings. Its an 3700+ Toledo E6 right ?

[WiK1d]

I have no idea, but I guess you're right. I thought that CCBWE stepping sounder familiar, same as my Opteron 170 (Which was pretty good though).

Which steppings are E4's?

Edit: Just checked AMD Geeks, seems most E4's start with KAXXX, KACAE being very good yes? And CABGE (Cabbage) being horrid?

[stunned_guy]

KACAE isnt good, best are KAB1E, KABYE and some other ones. that are newer ones the older ones had CABGE, CABCE, CAxxx and so on. Best was CABCE.
The CCBWE comes from the opteron family --> almost all were also not good but there were some like ccbwe 0550 vpmw that were great.

Oh? I saw quite a few KACAE's hitting > 3GHz on Air, are they bad on cold then?

But the KAB1E will most probably be cold bugged then, right?

I never said it would be good, I said it wouldn't be too much coldbugged Most CCBWE's will suck so much on air you'd need -50c at least to compete with the best coldbugged onces And -50c is alot, even on so-called "none-culdbugged" chips. Unless you have a multi of at least 12

BG's are usually quite bad. But my 150 WR was made with one of those (3778 MHz), so there are a few exceptions. CABCE were FX chips mostly. They were great because of them being unlocked, since they actually have a coldbug that will limit you on dryice if you have a multi of max 12.

KAB1E will have a coldbug, yes. But they usually OC very good on air, so you'll still get nice clocks. A few of WR's are made with B1's - 3500+ venice, 3800+ venice and 4000+ san diego, Opty 154 and opty 156. In fact, most of the highest SC 939 clocks are made with B1's (with the exception of the FX series of course)!

I see! So CCBWE's are bad on air, but might stand a chance on cold? And must have a pretty high multi?

Okay cool I understand a bit more now, thanks for all the help so far, you guys are great!

Are the 3rd and 4th characters the Memory controller spec?

SOME say that the 3rd and 4th letters are the memory controller specs. No idea if anyone ever proved it. I don't have any opinion about what it does, I just look at what the different combos behave at different temps

In general CCBWE's are so bad that they won't even have a chance under dryice. They made CCBWE's for Opteron 165, 170, 175, 180 x2 3800+, x2 4200+, x2 4400+, x2 4600+, x2 4800+, 3700+ and 4000+ but they have NO WR's. Not even close to it (unless I've missed something).

Just note that the singlecore BW's can be nice sometimes It's the dual cores that suck

[stunned_guy]

Knut is right....

In my opinion the 3rd and 4th place is the typ of the memcontroller...but i cant prove that. but many people in the web say that also.

CCBWE will suck hard...under air and coldness.

[knopflerbruce]

Knut is right....
CCBWE will suck hard...under air and coldness.

I just got an Opty 170 CCBWE. Orthos stable roughly 20 seconds @ 2.8Ghz / 1.41v / AIR - definately the heat that's the reason. One core is at least 10C too low, with that in mind both cores are just below 60c when they crap out at that speed/voltage. But still very promising for a CCBWE, I'm sure this one can do 3g stable on water *praying for a dice friendly coldbug*

Maybe I'll try some suicide shots on air, just for fun

[gianni-gt]

lol on air... or how cold is the norwegian air right now?

btw: just finished the OCTS promotion poster for the 2nd AOCM in Germany...



i know, i know. but i am/was the S939 master of our team.

Nice poster

Probably like 20c in the room atm. No idea really. My idletemps with a different chip are visible in the picture, I think That should give you a nice impression of my ambietns I think.

[Turrican]

very nice poster gianni

[stunned_guy]

Hehehe...freak...

Will try some cpus the next free days.

[knopflerbruce]

Hmm, I posted a screenshot of my Opty 190 and no-one noticed...?

Pay attention, folks, PAY ATTENTION!!

[stunned_guy]

I had seen that but i know there isnt such an cpu
what is default spedd ? should be 14x200 mhz if its really an 190.
