    Hello

    I bought Kingston HP 8GB 2Rx8 PC3L-12800SE DDR3L-1600 1.35V Memory card and my Toughbook cf 31 wont recognise it. The Toughbook boots up but it wont show in my system. Its just the Samsung same specs that shows on the system. It can be read in CPU-Z its exactly the same as the Samsung brand. Any idea guys?

    Its different because I have other ram that when installed my Toughbook wont boot at all, but this one boots to windows yet it wont show in the system.

    Any help ill be greatly appreciated.

    I have attached the CPU-z for reference.

    Does it work somewhere else? Can you install it as a single module, without Samsung one?

    Did you use msconfig tweaks to use Max memory size?

    So it means it never been enabled. Do you see any black marks especially DRAM ICs or the gold contact pin? Try rubbing the gold contact with a cloth and try again.

    I think you've bought a fake memory. Never buy RAM or flash on ebay.

    If you bought all 4,
    Do the other 3 work?
    Label the memory 1,2,3,4--- Which one is bad? Or are all four not working?

    Do you mean other ram installed won't boot when installed alone?
    Or won't boot when installed with the "bad" 8gb memory stick?

    Depends on seller sometimes they mix good and bad ones when ordered in packs.

    Try one stick at a time. When you find a good stick that boots into windows shut it down and try that stick in the other memory slot to see if it boots into windows. Just want to check to see if both memory slots are ok. In the past I have seen bad memory slots before.
