|DRAM? SDRAM ?|
||Several Memory module suppliers are offering PC133 modules with a performance setting of 3-2-2. What advantage does a 2-2-2 module provide?
||The first number of the 2-2-2 designation refers to CAS latency, so in short you are asking the advantage of a CAS latency of 2 over one of 3.
Adjusting a device to CL = 2 from CL = 3 will speed up access time from a READ command to the point at which data is available on the data bus (1 clock quicker).
Base on benchmark testing results, better performance improvements were found in the 2-2-2 setting over the 3-2-2:
