Memory present disabled

Hi all

I am trying to install 4 x 16G RAM on Gigabyte ga-7pesh2 (in the A0 B0 E0 F0 channels), but I only got 48 GB. The A0 and A1 show present disabled. If I try it in the C0 D0 G0 H0 channels, the D0 and D1 show present disabled.

Is there anything else I can try or may have done wrong? Thanks so much!

According to the motherboard specification GA-7PESH2 (rev. 1.0) | Server Motherboard - GIGABYTE B2B Service the board supports up to 32gb so I guess that explains, but you claim the board is showing 48gb which is really confusing
