<< CL2.5 and CL2.5? >>
That's the same thing!
CAS2, CAS2.5 and CAS3 are the CAS latencies for DDR SDRAM. - I believe the breakdown is 150MHz DDR, 133, and 100 (PC2400, 2100, 1600)
the 2100 for example stands for 2.1 GB/sec bandwidth.
PC133 is CAS2 and CAS3
Which are you referring to? DDR SDRAM or regular SDRAM?
