I'm getting only 138fsb @ cas2, about 141fsb@cas 2.5 on my amd 1700+, unlocked and multiplier at 12. (some hyundau pc2100)
I'm getting pc2700 because I do not want to gamble and its difficult to find crucial ram here in Australia. also its gonna be samsung, so leaves me a lil' room if i upgrade in the next few months.
