Yes, these are the CS now owned by Pace.Mr_Ace- send him a PM, maybe he sells at the right price , knowing he is also getting a 1066 Ballistix kit from me doing 1300 at 2,16V 32M- think he has too much ram now^^- technical and optical these are 100%
BTW- no difference with me between 500/600 and 400/600 in Ram voltage- but I think you have to look for the right GTLs, radaja- 1,38V NB is very high- my UD3 is stable at 1,22-1,24V in bios at 500/600, prime large, blend and 32M
