    Hi All,

    Just quickly to clarify that my brand new HyperX 1866 ram works at 1866Mhz on the T420. Like a charm.

    Regards,

    Harry

    Interesting. :eek: What are the memory bandwidth, memory latency and video memory bandwidth according to SiSoftware Sandra.

    Thanks, to compare with my results using 2 x 4GB 1333MHz RAM:

    Memory Benchmark
    Average 18 GB/s

    Memory Latency
    85.9 ns

    Video bandwidth
    8 GB/s

    So you are getting a big boost to the raw memory bandwidth but a lesser boost to latency and the video memory bandwidth.

    Errrr....don't you mean that he's getting a boost in all three departments?

    You might want to reread what you quoted. He DID state that there was a boost in all three aspects, just that one wasn't as large of a boost. ;)

    what about power usage? more speedy RAM = Less battery life? or it's doesn't play so big role?

    Hi,

    Battery consuption is not really an issue with me. I have it pluged in all the time, or most of the time..... However, seeing as the memory runs at the same voltage ( 1.5v ), as as supposedly takes less time to execute a given process, it should in theory use slightly less energy..... ;) Take the same analogy for cars and engines..... a 1.6 TDI engine at 120 km/h with 90Hp consumes more than the same engine with 110 Hp. You need less power to achieve the same results..... Think about it. Same principle appies to virtualization, and other areas in computing.

    Regards,

    Harry

    Interesting theory. I believe that RAM power consumption should be in proportion to the frequency - faster RAM has more access functions per second. However, it will take fewer seconds to complete the activity, so no overall power increase (assuming that RAM idle power consumption is small). Also, the CPU can be getting back to sleep sooner, which is another power saving.
