No, I'm not saying at all that AMD is publishing false claims - just that some info isn't necessarily available in public documents. I'm gonna stop here before I say something that'll get me in trouble..... ;)Quote:

Edit: It's a Venus of course!!! San Diego?? Duh! :stick:
...or, does the Venus got the D revision?? Is it San Diego? Maybe they don't have different names for D and E 1xx's, just like D and E Semprons?? :slap:
Once again I point you all to this
http://www.amd.com/us-en/assets/cont...docs/26094.PDF
BTW, since when are these s939 Optys FX chips?
It was quite clear that you didn't understand how the memory controller is configured in the 64 or Opteron with your "the A64's use only a true 64-bit memory controller" remark. Yet I'm supposed to believe that you have inside information (and yet somehow couldn't be bothered to read the published spec)?Quote:

I looked through page 109 and couldn't see what interested you so much. Could you explain?Quote:

So, it's it must be something else:
Theory no. 1: Only the S939 Opteron core is San Diego, S940 Venus Opterons are something totally different -> If this is the case, VVJ's prog "AuthScanner" doesn't show the core code name correct. That I doubt because he appears to have some level of official collaboration with AMD.
Theory no. 2: All San Diegos are Opteron Venus cores with some "abilities" enabled/disabled (for example requirement for registered ram). Codenames differ from their "parent cores" (like crippled Venices aren't Venices, but Palermos).
I prefer the 2nd theory.
I doubt AMD would design one core for Opteron and another for FX-line if they could design one core (that is the Opteron core) and disable all
"unnecessary" functions for desktop use.
I do believe he was one of the first to have a venice in his hands well before they were sold on the marketQuote:

The entire document, however, has lots of information regarding the difference, especially memory related, between s939 and s940.
It's true. Ecc or non-ecc both work on s939 Optys.Quote:

so this means that the BN in the opn code shouldn't be interpreted as san diego like one would expenct?Quote:

Both have similar architecture and same frequency but the Opteron has extra cache - not too difficult to figure out which is better.
You better read the review. Opteron s939 can use ECC as well as non-ECC unbuffered memory.
Venus vs. San Diego - the problem is this mess in names. There is nothing like San Diego core. Cores are named by letters and numbers. A64 3700+ s939 uses SH8 core in E4 revision. The name "San Diego" comes to say it is a s939 chip with 1 MB cache. That name is therefore a codename for a processor, not for a core. A year back a "Newcastle" was used to say it was an s754 chip with 512 kB cache... but no matter if it used DH7-CG (512 kB L2 cache) core or SH7-CG one (1 MB L2 cache with half of cache disabled).
Opterons for s939 use SH8-E4, exactly the same core as A64s w/ 1MB L2 use. And BTW, Opterons for s940 now also use SH8-E4 core. Only difference between s939 and s940 parts are that the memory controller is configured differently. But the core is the same.
Can't find the review that states that Opteron for Socket-939 supports non ECC memory, to blind obvioulsy.
But I came a cross this AMD document ...
http://www.amd.com/us-en/Processors/...,00.html#85258
AMD states again and again "supporting ECC unbuffered memory"
Nothing about non ECC memory support !
But the document might not be updated ?
Confused you will be.
See the RAMs I used - hereQuote:

To say the least.
As soon as I locate what ever AMD calls it .... you can see for yourself ...
Since very few 939 mainboards support ECC it is near impossible that the Opteron for 939 requires ECC. It would limit their application way too much.
