Opteron Identification

Currently I only have G34 examples shown but I will probably add C32 later and if requested Socket F.

6. Number of cores in hex  (as it has been pointed out twice now since IL AMD has abandoned the base 16 counting to keep from adding a second column... 
                                         not sure what base they are using since they did have a 20c ES AD chip that hasn't show up anywhere.  
                                         So... 1-9 then A-Z.  20c would be K by my guess.)

8. Core stepping
GN      MC D0
21      MC D0  
25      MC D1  
GO      MC D1
43      IL A0  (do not buy, unstable and removed from bios support)
44      IL B0  YMMV
45      IL B1    
GU      IL B2
54      AD C0 (Unconfirmed)
HK      AD C0

Retail information mainly gathered from cpu-world.

Gathering the ES info and connecting the dots was my doing.
I am still trying to work out what those last 2 digits of the part number mean though lol.

6. Number of cores in hex ??

16 base 10 = 10 in hex, so not quite hex after this point

Yeah that got pointed out in irc... It looks like they abandoned hex with IL.
Answers my question as to what they planed to do about the 20c chip.
