Hello everybody, I have recently bought a Lenovo G510 laptop with the following specs:

As you can see, I have 4 GB of RAM installed and the windows sees it correctly, but when I was playing a game using the AMD GPU, I got prompted that I was running low on memory. Naturally, I opened up task manager to see what exactly could be taking up 4GB of RAM memory considering The game should only take like up to 1GB or two, and I was running no other heavy duty software at the moment.
Smite was taking up a bit over 1GB of RAM and when I switched to percentage values, it displayed smite as taking over 50% of the available RAM, so I concluded only 2GB of RAM were initially available.
My windows is running an x64 OS so that shouldn't be the problem, and it also displays 4GB in the System window.
My guess would be that 2GB of the available RAM are allocated to the Onboard graphics card (Intel HD 4600) as that is the graphics card that is working when I'm in win explorer or other software like Chrome. The AMD Graphics card kicks in when I'm in-game, as I am running with Switchable Graphics. I have tried running UMA Graphics instead of switchable graphics in BIOS, but the card that got de-activated was the AMD one, so no solution there, so still, I have no ideea if the intel GPU is actually the problem, or if something else limits my memory.
When running nothing but the OS this is what the task manager displays:

This may have been a topic suited for the Win8 section of the forum, or the Graphics section, but as I am not sure, I chose Memory because this is the actual problem, I hope I am not off-topic.
