So I have installed a hyperx kit 16gb and 5gb of it is reserved any suggestions?



issue was compablity
Hello Fellas,
So I have an issue where almost half of my ram is being hardware reserved. I tried most options including turning on the iommu option in bios and disabling limited ram in msconfig however, the issue still presists.

The Issue:
I have installed:
2x 4gb of ram on slot 1 and slot 3.
2x 2gb ddr3 on slot 0 and slot 2.

I have a ASUS Sabertooth 990fx Motherboard and on boot it only shows 6gb available, looking at the bios memory management it detects that all the ram is seated with the same speed. I have checked each ram individually and it works on slot 0.

Can anyone help me out?
