Wow awesome link, thank you for that.
Note that this website is very barebones.
the latency (cl) of dram is like this: 16-16-16-32 (for example)
but sometimes, though its rare, a manufaturer will put cl16 in the packaging
while the other numbers (which are just as important by the way) will be
16-22-19-38 or something like that.
usually its not, but checking first is good.
