    Ram is 80% hardware reserved after a restart.


    So, i have a PC home that i use to connect with my laptop to do "heavy" tasks that are to slow on my laptop or he just got to hot.
    how ever, after a restart/power off i don't rly know, my PC have 10gb of 14gb hardware reserved i don't have iGPU or thinks that need system ram. Before the shutdown it works all fine. I tried everything, boot settings bios reset but nothing works.

    Hardware Reserved RAM.

    hi all,

    I upgrade my window from 8.1 to window 10, and the usable ram only 3.2 GB.

    But recently i upgrade also my RAM to 8 GB, but the only maintenance on 3.2 GB usable , and the remaining go through the hardware reserved (4.8 GB)

    Anyway to solve this ??

    Ram is 80% hardware reserved after a restart.

    Hardware Reserved 4GB (DIMM Slot 1B)

    So recently my task manager started showing that only 12GB of my 16GB DDR3 RAM in Dual Channel was available stating "Hardware Reserved 4.0 GB"

    These are the steps I've currently taken to attempt to rectify the issue.

    1. Flashed BIOS
    2. Wiped OS and installed to a new drive
    3. Set max page file size to recommended (2.5GB)
    4. Maximum memory isn't enabled in advanced boot options
    5. Replaced the odd stick of RAM (I had a Kingston HyperX Fury) with the same model (now all Corsair Vengeance) so now all sticks match
    6. Resetting CMOS fixed it for a few hours before returning.

    I want to avoid the idea that the DIMM slot is faulty due to a CMOS reset fixing it (even if temporarily).

    The RAM I'm using is: CMZ12GX3M3A1600C9 (3) and CMZ4GX3M1A1600C9 (1) Both the same model of RAM, but the 3 came in a kit for 12GB whilst the other came as a single kit of 4GB, hence the slight difference in the part numbers.

    The motherboard I'm using is 990FXA-UD3 R5.

    I'm asking as a seperate question due to the fact I've tried every other suggestion in the other questions and now feel that my situation is unique enough for it's own question.
