Re: 100 MHz.. nearly.

Hi!

CL2 means "CAS latency equals 2 clockcycles". This is the amount of time (2 clockcycles = 15ns at 133MHz) that has to pass after the column adress has been sent to the SDRAM prior to getting any data from it. At least I think it's something like this. :)

CL3 is obviously a latency of 3 cycles, which is 3/2 as much time as 2 cycles (22.5ns)... :)

If an SDRAM module labeled as 133MHz CL2 is run at 66MHz instead, only 1 66MHz clockcycle would actually be needed (1 clockcycle = 15ns at 66MHz).
