I have 12GB of ram installed and is recognized by bios. Ubuntu says I only have 9.7GB.
I am running 2 x 4GB and 2 X 2GB. All are DDR3 and I have the larger pair installed in the blue slots (primary) and the smaller sticks in the black slots. The motherboard is a MSI 970A-G43 that can take up to 32GB. I have a 256MB gpu card installed and the motherboard does not have on board video.
I have installed each pair of memory (in the blue slots) without the other and they all are good.
I know it is ill-advised to install ram of different sizes/type, but I feel like if BIOS sees it, Ubuntu should too. How can I correct this?
