    RAM Limit on 64-bit Windows

    Hey Guys

    I have got myself a new laptop recently with the following specs

    It's a HP Pavilion G6 2253SA

    Intel Core i5 3210M
    Intel HD 4000 Graphics up to 1.6GB shared graphic memory
    6GB RAM DDR3 at 1600MHz
    1TB HDD 5400RPM
    Intel HM76 Chipset

    Anyway I have a 64 bit copy of Windows 8 Pro installed and this has been re-installed as I did not want to bother with all the Manufacture software that was not necessary for my system

    Click image for larger version

    This next part sounds silly and fussy

    Anyway even after reinstallation my ram still does not go up to 6GB as it only peaks at 5.89GB and that 103MB is reserved for hardware

    I plan on upgrading it to 8GB of ram however I do not want to upgrade it if all the extra memory is just going to be reserved for hardware

    Thanks to any replies

    Simple answer -- Integrated video. Your on-board video uses system RAM since you do not have a dedicated video card

    Ahh I see but if I install more RAM since my board supports up to 8GB, Will I actually get the RAM or will it be thrown into hardware reserves

    Hi there
    Max RAM for W8 is 192 GB -- so you shouldn't run into those sorts of problems -- 6 - 8 GB RAM will work just fine. Some RAM is always reserved fort BIOS / Video --even if you have a separate video card.

    (The 192 GB is a software limitation rather than the limitation of addressing 64 bit hardware itself).

    You''ll get the extra RAM but you will ALWAYS have some RAM reserved for video. My Dell laptop is the same way (4GB, 3.8 usable). So if I was to upgrade to 8GB it would say 7.8GB usable. H

    Hope that helps =)
