CL is commonly the Column Address Strobe Length in clocks. That would be too much to print on the chips, so the acronym could be CL. Since a CAS lenth of 12 is rather longish, I'd have to guess it was 15 which at such printing could be read as as 12, but it's not 15 (or 12) since some will drop the "." to fit the printing in.
And you should get memory from a place that will exchange it or stand behind your selection (like www.crucial.com)

Does anybody know what the "CL" spec. on the back of a DIMM module refers to? I've been shopping around for extra RAM for my laptop? It's currently using a 256MB 2100 266(FSB speed?) DDR DIMM with "CL12" but I've seen similar DIMMs that have "CL2.5". Is this "CL" spec. relivant when choosing RAM on a laptop? Thanks
