need to upgrade sever memory. Currently, by factory installation, server contains 12GB (2gb x 6). Server contains 2xcpu, and 18 memory slots. Each cpu has dedicated 9 slots, or 3x3 memory channels.
I have bought 2x 4GB, and was installed into each 1 channel empty slot. But server/bios is refusing this kind configuration!
I'm confused, as currently not sure what is proper way to upgrade memory.
Powerpoint schema attached.
Thank you in advance for help.
