Hello,
I had two rather slow PCs and the RAM slots were not full, so I bought some sticks to improve the PC: a HP xw 4300 Workstation and an Acer Veriton M420, but both PCs still show 3.5GB usable in the "system" page regardless of whether they have 8, 6, or 4GB.
What should I do??
Thanks everyone for a little response

Configuration: Windows / Chrome 52.0.2743.116

    Hello,
    Are your PCs 32-bit or 64-bit?
    For reference:

      Thank you for your response, as my PCs (running Windows 10 each) are 32-bit, I understand that they cannot have more usable addresses.

      It's a shame because buying 4 Kingston sticks at 2GB each cost me about €160.

      Moreover, the software AIDA64 tells me that my motherboard, as is, supports 8 GB of RAM.
      I believe this software is reliable though.

      Thanks again
