Only 2 GB Ram being used by Windows despite having 4GB Installed

[GRZ]

Hi,

I have 4GB of RAM installed in my system (2 X 2GB) however when I start the task manager it is only showing 2GB of it being available.

I have checked via the BIOS and CPU-Z and both show 2 sticks of 2GB each.

The task manager also shows 4GB SDRAM on top but on the usage graph is is showing 2 GB. Similarly in the System dialogue of windows it says the Installed Memory - 4GB (usable 1.99GB)

Why is only 2 GB usable? I have a 64bit system

Do you have an on-board/integrated graphics card or a discrete graphics cards? Can you list out your other hardware?

What is your windows version?
If it is windows 7 starter, then 2GB ram is max.

I have a dedicated graphics card. It is the ATI HD5770. It has 1 GB of GDDR5 memory of its own.

Apart from that I am using a MSI P55GD65 motherboard with an Intel i5 750 processor. A 1TB seagate HDD is also installed.

Let me know if you need any other information

No I am not using Windows 7 starter. I am using Windows 10 Pro version.

Windows takes about 2 gb just for itself, so it should show ~2gb in use and ~2gb available.
With only 4GB of ram, a 64-bit OS is kind of overkill, and will perform slightly worse than a 32-bit version on that 4gb machine.

2GB hardware reserved, was the RAM came in a set, or was it 2 individual stick ?

The RAM came in a set. There are two sticks but they came together

I tried adding some more RAM to my computer in the form of a 4GB stick.

Now the PC has 8GB of installed RAM however it is still only using 2GB with 6GB being shown as hardware reserved.

What is happening?

It usually mean the RAM stick not working together(speed, timing, voltage, etc). try taking the 2x2GB RAM, should give you 4GB.

Have you tried updating to the latest BIOS version?
