SUPERSERVER 5016T-TB User's Manual

Memory Support

The X8STi supports up to 24 GB of unbuffered ECC or non-ECC DDR3 1333/1066/800 in 6 DIMM slots. Populating the DIMM slots with a pair (or pairs) of memory modules of the same type and size will result in interleaved memory, which will improve memory performance.

Populating DIMMs

For memory to work properly, follow the table below for memory installation:

Memory Population (UDIMM Only Routing)

DIMM	DIMMs	DIMM Type	POR Speeds	Ranks per DIMM
Slots per	Populated		(in MHz)	(any combination;
Channel	per Channel			SR=Single Rank,
				DR=Dual Rank)
2	1	Unbuffered DDR3	800,1066,1333	SR, DR
		(with or without ECC)
2	2	Unbuffered DDR3	800,1066,	SR, DR
		(with or without ECC)

Population Rules: Any combination of x8 and x16 UDIMMs, with 1Gb or 2Gb DRAM density.

Memory Population (UDIMM 3 DIMMs per Channel Routing)

DIMM	DIMMs	DIMM Type	POR Speeds	Ranks per DIMM
Slots per	Populated		(in MHz)	(any combination;
Channel	per Channel			SR=Single Rank,
				DR=Dual Rank)
3	1	Unbuffered DDR3	800,1066,1333	SR, DR
		(with or without ECC)
3	2	Unbuffered DDR3	800,1066,	SR, DR
		(with or without ECC)

Population Rules: Any combination of x8 UDIMMs, with 1Gb or 2Gb DRAM density.

Maximum Memory Possible

Single Rank UDIMMs - 12GB (6x 2GB DIMMs), Dual Rank UDIMMs - 24GB (6x 4GB DIMMs)

Both unbuffered ECC and non-ECC DIMM modules are supported by the motherboard. Using ECC or non-ECC memory on your motherboard depends on the CPU installed.

Due to OS limitations, some operating systems may not show more than 4 GB of memory.

Due to memory allocation to system devices, the amount of memory that remains available for operational use will be reduced when 4 GB of RAM is used. The reduction in memory availability is disproportional. Refer to the table on the next page.
