I've done a little looking but can't seem to find the answer that eludes me. So what exactly is CL2 ram? I've also heard it referred to as CAS2 ram, are these two different names for the same thing? Also, I've seen it referred to as CAS2 and CAS 2.5, if I read it right CAS2 is better than CAS2.5, is that true? Lastly, how do I tell if a particular type of ram is CL2(CAS2) ram? Thanks.
