Single Core Stepping
It must be noted that the chances of getting any of the listed stepping numbers below are now slim to none, however you can probably find them listed on ebay or for sale on enthusiast sites. The following are listed from what would be considered to best to the worst
1. CABNE 05xx (excluding 0540)
2. CABYE 0540
3, CABNE 0540 / CABYE 05xx (excluding 0540)
4. CAB2E 05xx
5. CABGE 05xx
Note: It should be noted that the CAB2E stepping cores are known as to be either hit or miss, some are yielding overall good overclocks while others struggle beyond 2.75GHz
Dual Core Stepping Numbers:
There is little to no information availible on multicore stepping and specific results pertaining to specific stepping numbers at this point and time, there simply aren't enough Denmark Opterons floating around yet. The only known stepping as of yet is the CCBWE, most of which are week 30s, which appear to overclock better than comparative Athlon X2 processors. However, there have been some week 34s which have rather poor overclocking results when compared to the earlier 30s.
