So my motherboard has two ram slots, and the bios only detects slot 2.

The PC only boots with a ram in slot 2, if only slot 1 is occupied, it wont boot.

Windows 10 only detects half my ram as well, sometimes it detects 8gb but with 4gb "reserved for hardware".

And CPU-Z detects both rams.

How do i fix this problem?

Ps: msconfig max memory is unchecked.

That sounds like a partially dead or partially unseated RAM slot. What I'd assume is happening is that the memory itself is not connecting, but the connections for the SPD chip that CPU-Z detects are still working.

A free troubleshooting step is to reseat your CPU - a lot of memory problems are in the connection between the CPU and the socket.

This is common with systems running windows 32 bit with more than 4gb of ram. Are you sure you are running 64 bit windows?

Did you let your motherboard know about this in the bios?

I've read somewhere else that it might be some pins on the cpu slot on the motherboard, but i'm scared to take the cpu off and break something

can you go into the bios and disable the igpu then. 4gb hw reserved is because of a active igpu (the hardware reserved is the ram being dedicated for vram for the igpu)

Those are 2 photos of the bios, you can see it says none on slot 1, but there is one ram.

so... i'm back, today the problem came back, it only says there's 4gb of ram, but there's 8. The CPU reseat did work, but if i just have to do it over and over again, then it didn't really fix the problem. Does anyone know how to fix it?
