Hello,

So, i have an R720XD server and im trying to get 768GB RAM Memory (24x32GB) and, when i put 16x32 memory, its everything okay, server telling me I have 512GB RAM Memory, but when i start added another rams, to the "Green slots" amount of ram start goes to random (386GB/256GB) and i just cant get more than 512GB ram, i use 2xE5-2690v2, bios is the nevest (2.9.0) and memory what i use is all 24 pieces of 32GB 4Rx4 PC3L-10600R-9-12-AB0. HMT84GR7MMR4A - H9 D8 AG . Any ideas why? Of course idrac didnt post any troubles, but im getting message from start. That "Warning: The number of ranks on this device is not supported." So, how can i get 768GB Ram when 32GB memory stick have 4Rx4 or 4Rx8 ?
