Looks like the micron F die goes into 2 bins , First the PC-4000 plat XTC 2 gig set and then after that the PC-4000 gold XTC revision 1.1 according to sources at OCZ. I'm going to test out a 2 gig set of the pc-4000 xtc on Monday compared to the ballistix 4000 sets. In any case it's good to see micron ic's are making the rounds again for what it is worth.
