More specifically, the HP T640 device.

The manufacturer declares compatibility with CL22 latency and 2400 MHz clocking. If I buy RAM with CL17 and 2400 MHz clocking, will it work?

    Computers are not specified for a specific RAM latency (the number in CLXX describes the latency of the RAM), you can put whatever you want.

    Just note that in the case that you add a second stick of RAM and that the latencies are mismatched, the computer will pick the slowest of the two (in your case, CL22, so that won’t change anything latency-wise)

      The bigger number is slower because it’s latency represented in clock cycles, and can only be compared for memory rated for the same frequency
