8GB RAM but only 2gb usable (windows 10 32 bit)

[HurtfulAxis]

I have a problem with my RAM. I have 2x4GB same rams but only 2GB is usable. Why? I tried to fix this ptoblem through msconfig (system configuration). I unchecked the box for maximum memory. I have Windows 10 32 bit. Please help me fix it.

Because your windows 10 is 32 bit.

Try windows 10 64 bit or any other windows in 64 bit.

As Rayler said, you need a 64bits windows os to use more than 4gb ram.

Are you using an amd apu or intel cpu and using the integrated graphics? That might explain it. As others suggested, there's a 4gb memory limit with 32bit windows and many times not even that much. It may cap you at 3.7 or 3.8gb.

If you're also using integrated graphics the igpu may be using 1.7gb for video ram since integrated graphics don't have their own video ram like a dedicated gpu does. It shares the system memory. 3.7gb usable minus 1.7gb for integrated graphics and you'd only have 2gb left for windows and programs. You should consider getting a 64bit version of windows to use all the ram.
