What does "CL" stand for?
CL stands for CAS (column address strobe) latency, which is the number of clock cycles it takes before data starts to flow after a command is received. Low CAS latency at a given frequency is faster than high CAS latency at that same frequency. (For example, CAS2 is faster than CAS3.) However, lower CAS latency will NOT necessarily make your system faster. Your computer will only run as fast as the "slowest link" in your system, so you can't speed up your computer by adding memory that is faster than your current memory. The way to make your system faster is to add more megabytes (MB) of memory.
In general, we recommend using parts with the fastest speeds. This will give you the highest level of compatibility and future upgrade path.
If you don't know the CAS latency of the memory you currently have installed, don't worry; any of the modules listed in the Memory Advisor tool are guaranteed to work in your system.
Those sticks will probably work ......
However , they would work at the speed of the slowest one.......You should really check with Toshiba
