Let s see what they say about that one too. When I first bought my Rev. 2 memory some months ago, this was listed as 4.5ns clock access time instead of 5. 4. I don t know. Here s a very basic summary of what they are. Obviously, the less clock cycles, the faster it happens.
Memory is accessed by row and column, and the row address is processed first.
This number is describing how many clock cycles it takes to do this. This number describes the clock cycles required to do it. In spite of the significance of the CAS timing and all the coverage it gets, we still have another set of numbers that can make a difference in your memory bandwith. The first number stands for Row Active time, and the second for Row Cycle time. I m not a technician, so I ve exhausted my knowledge at this point.
