Usable Ram Issue

[Riddo]

I have a amd a4 4000 apu paired with gigabyte f2a55m-ds2 motherboard. I added a 4gb ram stick to it along with an existing 2gb stick but it shows only 2.47 gb usable. In case of only 2gb ram it showed 1.5 which was understable. I tried all the tricks available on youtube. Like changing maximum memory and disabling page up memory but nothing seems to be working. Please help guys.

are the 2 sticks different speeds? Which ddr version?

it's probably reserved by the integrated gpu

there might be bios options to cap the max ram amount the igpu can reserve, but I don't know for sure on this particular motherboard.

The bios terminologies seems to be very confusing.

 You go to IGX configuration and then it's called UMA frame buffer size
