If you got the stuff from a decent company it will most likely be CL2, you can check you get it by running the Apple System Profiler (in your Applications > Utilities) and it will most likely tell you.
im looking to upgrade my dual 533's ram, max upgrade hopefully. can anyone suggest some companies selling quality 'hi-po' (oops, car term.. ) ram?? what I would like *ideally* is 3 512 CL2 dimms. but have only seen CL3. does no one make a 512 CL2 dimm???
funny thing just after i posted this my buddy recommended crucial as well. so i took a trip over there and decided the quantity was a little more important then the quality. bought 3 dimms, 2 day fedex shipping for free as well, sweet.
