Hva er CAS Latency egentlig?

[Knutgrus 975]

Driver å skal oppgradere for tiden. Henger ikke med i heletatt. Hvor stor forskjell er det mellom ei brikke som har 3 CAS Latency mot ei som har 2 CAS Latency?

Uansett, det det koker ned til er:

 

"the CAS Latency (CL) refers to the length of time, in clock cycles, it takes for a request sent from the memory controller to read a memory location and send it to the module's output pins."

 

"When selecting a RAM card the lower the CAS latency rating the better your system will perform. Current DDR2 RAM should have a CAS latency of about four, or optimally three."
