I got Stepping B0 Revision 4, the LAST "ES" batch =(, I have seen some B1 Rev. 5 around but havent heard anything, my only question is "does anyone has this 2 settings in cpu-z?" im using G.sKill pc5400 and found this detail today:

Check:
I Have the memory Divider at 1:2
Cpu Z doesnt let me see the 2 cores option, it marks both cores (I have seen lots of photos like this one, no problem so far, but does anyone knows why?)
The Core Duo Image in Cpu Z doenst appear... same as before, I have seen photos with and without it, but my real question is "what happend with the memory divider? does anyone have it like mine?"
btw, its an ABBYSMAL difference between this beauty and my old t2400!!!
