What does CL 2.0 stand for on ram memory?

Answer 1

Clock Latency .

Clock Latency (CL) is a common term used to describe the rule used for calculating when the memory can be read from or written to. The memory CL is normally defined as 1.5, 2.0, 2.5, or 3.0. The lower the number, the faster the memory can be read from or written to. We need to establish why we are seeing non-integer numbers here, if computer clocks only work in whole or integer numbers. The specification is referring to real clock cycles or ticks, not DDR timing cycles. So 1.5 Base Clock Ticks at 200 MHz. = (3.0 DDR clock Ticks at 400MHz. / 2). The less expensive the memory is, the higher the Clock Latency (CL) number is. Standard memory uses CL=3.0 DDR RAM, where-as, Higher performance systems use CL=1.5 or CL=2.0 memory, which is available at a slightly higher cost. Let’s use PC3200 CL=3.0 RAM to be our benchmark. If we purchase PC3200 CL=2.0 RAM, we have decreased the time it takes to be able to read from or write to the memory by 33%. If we purchase PC3200 CL=1.5 RAM, we have decreased that same time by 50%. Notice that we did not buy faster frequency RAM, we bought lower Clock Latency (CL) RAM to get higher system performance.

Answer 2

"CL" is for Clock Latency."CL 2.0" means that RAM need 2 seconds to access or procces the given task..

Answer 3

CAS Latency (CL) is the ratio between column access time (tCAC) and the clock cycle time (tCLK), rounded to the next higher whole number.

Answer 4
