    一共四组内存槽，两组内存槽插新的内存，两组内存槽插旧的，每组槽插2根

Answer 3

分开插是啥意思？

Answer 4

谢谢楼上的，我把新旧内存分开插，就可以了

Answer 5

Four, eight, and sixteen FBDIMM configurations of the same FBDIMM are supported.
All FBDIMM's in a Branch must have the same Sun part number.
All FBDIMM's in the server must be the same capacity.
The minimum requirement is four FBDIMMs in the Channel 0, DIMM 0 slots.
