Memory Support

The X8STi/X8STi-F/X8STi-3F/X8STi-LN4 supports up to 24 GB Unbuffered ECC or Non ECC DDR3 1333/1066/800 in 6 DIMM slots. Populating these DIMM slots with a pair (or pairs) of memory modules of the same type and same size will result in interleaved memory, which will improve memory performance.

DIMM Module Population Configuration

	DIMM1B
Channel 1 Slots	DIMM1A
DIMM1A Slot
Channel 2 Slots	DIMM2B
	DIMM2A
Channel 3 Slots	DIMM3B
	DIMM3A

Note : The motherboard may NOT boot if DIMM module(s) are installed in any of the black slots but none in the blue slots. The first DIMM mod- ule must be installed in DIMM1A, and all blue slots must be filled before populating any black slot(s).

Maximum Memory Possible

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

Note 1: 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.

Note 2: Due to OS limitations, some operating systems may not show more than 4 GB of memory.

Note 3: Due to memory allocation to system devices, the amount of mem- ory that remains available for operational use will be reduced when 4 GB of RAM is used. The reduction in memory availability is disproportional.
