That depends on how aggressive your memory timings are. Micron is some of the best ram around. Just from some personal experience, I have a 256mb stick of Infineon (also good stuff) that is CAS3 but runs CAS2 will all interleaving maxed-out.
It depends on the stick. Being it's Micron, I'd say almost definitely, at 133MHz. Maybe more. Play around w/it and you'll find out. Worse case scenario is no boot. Reset CMOS and try again. Good luck.
