Yes. My Corsair (qty...10?) and OCZ kits (qty 2) all came in clear plastic packaging. Haven't had an issue yet. I suppose that it's to improve their shelf appeal, but I, too, would prefer they come in antistatic bags. > > Silly question: Does DDR3 ram carry any sort of "PC3xxx" value?

At 1333MT/s (667MHz), PC3-10600 1600MT/s (800MHz), PC3-12800. The numbers are each relevant, as they signify some element of the module. The PC3-xxxx is the peak throughput in MB/s, the DDR3-xxx is the number of transfers per second, in millions. (MT/s) Then you have CAS latencies...
