Hi, i am currently thinking about purchasing one of these cpu. What stepping is the better one? What do all the prefixes mean?

Thanks,

529th

EDIT: yes for overclocking :)  which is best??? thanks!

More about : opteron 165

Opteron = High-End Enterprise quality AMD64 CPU

1xx = Socket 939
2xx = Socket 940 Dual CPU
8xx = Socket 940 for Quad and 8way CPU configurations

Available in Single and Dual Core supports Dual Channel DDR SDRAM

2xx and 8xx Opterons support NUMA and can each support dedicated Dual Channel DDR SDRAM so the more CPUs you add the more memory bandwidth you have :-D


Athlon = Mainstream AMD64 model

Available in Socket 939 and Single Core or Dual Core Supports Dual Channel DDR SDRAM


Sempron = Entry-level line

Available in Socket 754 available in Single Core Supports Single Channel DDR SDRAM



Best price/performance = nForce4 + AMD64 Socket 939



The Opteron 165 is a Dual Core Socket 939 CPU with a 1.8GHz Core Clock, 2x1MB L2 Cache, 64KB+64KB L1 cache and 1GHz hypertransport in full duplex (1GHz in each direction).




EDIT:


What stepping are you considering and what prefixes are you referring to?

What parts are you planing to use with the Opteron 165? [ mobo, RAM, PSU, HDD, VGA, etc ].

You havent understood what he means. He is asking, as was i in another topic :twisted: , whats the best core for overclocking as far as opteron 165's are concerned?

I suspected as much however the OP does not mention OC'ing anywhere... Nor did I know which "prefixes" he is referring to. So I posted some general info instead.
February 11, 2006 8:19:34 PM

Fair nuff.

So does anybody know bout the cores? Or where to find out bout them?
February 11, 2006 8:20:32 PM

I have one ( in wife's computer :x ) got 170 in mine. Very good procs, both r oc to 2.6 one on air other on liquid. Only down fall is that the mutiplyers are locked and can only go down. So to OC you need to raise the FSB but make sure you have good ram DDR 500, 550, 600
Just so you know there is no difference in either cpu when OC'ed at stock the 170 is a little faster only because of it mutiplyer. So please save the cash and get the 165 :!:
February 11, 2006 8:25:51 PM

So what are the respective multi's?
February 11, 2006 8:30:30 PM

It is my understanding the Single Core 939 Opterons use the Venus core and the Dual Core 939 Opterons use the Denmark core.

Beyond that I do not know a whole lot of details about those specific cores.

I am not sure what the different steppings are or if it even possible to find a particular stepping.
February 11, 2006 10:56:14 PM

165: 9 multi x 200fsb= 1800 or 1.8 core clock

170: 10 multi x 200fsb= 2000 or 2.0 core clock

175: 11 multi x 200fsb= 2200 or 2.2 core clock

180: 12 multi x 200fsb= 2400 or 2.4 core clock

if increase the fsb you change the core clock and ram 1:1 ratio depending on bios options!

my opty's run: 165: fsb 290x9 multi =2610 or 2.61/ 170: 265x10 multi = 2650 or 2.65

Hope you got it bro, any questions I'll try to answer them best I can

Yea and from what I was told the Denmark core is basically the Toledo as used in the FX-60

For best stepping, check extremesystems. For opn codes check here

May I ask why?
February 13, 2006 2:35:22 AM

What does the CCBWE & VPMW mean???
February 13, 2006 2:54:46 AM

I have no idea what each letter in a stepping means. That's just the model number and fabrication label of it...
February 13, 2006 3:12:10 AM

That's strange! Since opn codes are year, week, what year had 56 weeks in it?
Why do I think you got a chinese special?
February 13, 2006 3:14:24 AM

Not sure, but I read somewhere on AMD's site that was week #56, ultra new.
February 13, 2006 3:22:55 AM

Did you write down the opn code? or do you have the chip handy?
In the second set of alpha numeric sequencies, the first number (after the letters) will be followed by 0, and then probably 5 or 6 depending on the year (o5 or 06). The next 2 digits will be the week. If it's a 56, then either it was made in a year with 4 extra weeks, or it's a chinese knockoff.
February 13, 2006 3:23:54 AM

Do you have pix of the CPU?

Was it OEM or retail boxed???

There are scumbags out there re-marking CPUs so you have to watch out ( I believe that's the Chinese Special the wise person above was referring to).
February 13, 2006 3:24:17 AM

It's not a chinese knockoff, it was purchased at zipzoomfly.com. I'm not going to take off my massive heatsink to look at it >< it also came in the unopened opteron box...

if it was, wouldn't it be oem? i think they are all prefabed in Germany but don't quote me.
February 13, 2006 3:26:18 AM

it isn't OEM!
February 13, 2006 3:28:32 AM

man if they changed it so they can't be overclocked im gonna phreak...
February 13, 2006 3:29:28 AM

They changed it so you can't do jackshit. It fails 2 superpi 32M tests at stock!

MOST knockoffs are OEM but there have been cases of nearly PERFECT Retail Boxed knockoffs.

To the best of my knowledge all AMD64 Cores are made in Germany (just the die), assembled in Malaysia (die + socket 939 package) and boxed who knows where.


This particular one was not OEM, it was retail boxed.

It is a lot less likely it is a knockoff tho not completely impossible.
February 13, 2006 3:47:07 AM

I reread your post. It says CCBWE 0551VPMW. That means it was made in year 05, week 51.

That would mean it was most likely manufactured at the end of 2005 The week of Dec 18-24 2005 I would think.

It's hard to tell if they shut down for Xma$$ and or new years or if their quality control was on vacation that week or enjoying those excellent German Lagers @ work ;-)

I'm a geek and I don't drink, dunno if the AMD geekz in .DE drink either... hard 2 tell. My comment was not intended 2 offend anyone so please don't read anything into it.

Semper Fi Linux on! :D 
February 13, 2006 3:55:08 AM

thats pretty fresh off the grill
February 13, 2006 3:58:47 AM

yeah no shit. its very possible they tried to put a cap on overclocking by putting the crappy cores that failed elsewhere as 1.8 ghz sets...but it fails at 1.8ghz stock on stock voltage ! double you tee eff...
February 13, 2006 4:15:10 AM

Hm, they say theyre cores fail as well. I'll try prime @ 2.6...

CCBWE & VPMW is what i don't understand.

Well, i was going to put it in the New ATi 580MB chipset but i hear its not coming out until June??? if that is true, i will probably put it in an A8N32 by Asus, i'm still confused on which RAM to get but i think i heard i should get the best RAM to overclock and i'd probably go with 512 sticks, i just purchased the Enermax Liberty 620, a WD1500ADFD + 300GB SATA storage (currently have 300), and haven't decided on a VGA yet; the pc is for gaming. So, i'd like to be able to overclock it as much as i can. I'm considering maybe going with the 175 Opty...

Well I am not sure if I can explain it any better... they are just manufacturing codes.

There have been a few problems reported with the "CCBWE 05 51 VPMW" batch so I would try to avoid that!

Try to get "CCBWE ?? ?? UPMW" instead


The ASUS A8N32 is great.

For a VGA I would suggest a 6800GS or 7800GT depending on your budget. Anything more than the 7800GT is not worth it in my humble opinion because you're paying way too much.

You can always upgrade the VGA later on. Also nVidia's response to the X1900 is on the way I'm sure... I would guess it will be released in the next 0-30 days or so.

At that point competition should drive all prices LOWER, unless energy prices drive the price higher.
February 14, 2006 11:06:08 PM

meh, i got my friend's up and running at 2.6. it will drop occasionally at 2.7 but it did pass superpi at 2.7...
the whole core0 failing was a superpi software error. however, core0 is still significantly (and noticably) weaker than core1 and if it they were equal i might achieve 2.75 totally stable
February 14, 2006 11:40:59 PM

Hmm interesting :-)

Do you have VNC?
February 15, 2006 2:52:22 AM

whats the difference between a 165 and a 175 besides the default speeds? is the 175 just more stable at 2.2 so is that why its marketed that way? I know they can just be marketed like that to get more money but... im talking stabilty in overclocking. Could the 175 be overclocked higher then the 165???

thanks,

529th

EDIT: im up on the multipliers e.g. 165 x9 & 175 x11
February 15, 2006 2:56:42 AM

529th, chips are mass produced. some chips don't make the cut of a super-high performing processor like the 180 chips do. rather than throwing these away, amd sells them as other chips for different market segments. obviously, some of the chips that were designed as a high performance opteron would be able to perform just as good as many 180's and be stable at a 180 stock speed. amd can't take that risk.
so, basically, as you move up, the silicon is almost identical-but the chips are rated higher. this is why only 170's and above can get extreme oc's if you get an awesome stepping but for the most part they will both max out at about 2.75. if you want to try your luck, go for a 170. if you are going to be rather conservative, get a 165. however, for some odd reason you never really see 180's and 175's getting as high as the lucky 170 steppings do, maybe because fewer people buy them due to price, maybe due to the batches they are made in. also, as you move up, you get a better max multiplier to use.
