2.8 Installing the Memory
Before installing memory, ensure that the memory you have is compatible with the
motherboard and processor. Check the TYAN Web site at http://www.tyan.com
for
details of the type of memory recommended for your motherboard.
 The Sandy Bridge-EP/EX processor is a quad-channel design with a total of 4
DDR3 channels
 This platform supports Unbuffered DDR3, Registered DDR3, and LR DIMM
(Load Reduced DIMM) DDR3 for buffered memory solutions demanding
higher capacity memory subsystems.
 DDR3 data transfer rates of 1066, 1333, and 1600 MT/s are supported
 Each memory channel is 72 or 64 bits wide for ECC or Non-ECC
 Both 1.5V and 1.35V DDR3 DIMMs are supported
 Gb, 2-Gb, and 4-Gb DDR3 DRAM technologies are supported for these
devices:
— UDIMMs x8, x16
— RDIMMs x4, x8
— LRDIMM x4, x8
 Up to 8 ranks are supported per memory channel. DIMMS may be 1, 2 or 4
ranks per module.
 All installed memory will automatically be detected. No jumpers or settings
need to be changed for memory detection.
 All memory must be of the same type and density. Registered, Unbuffered,
and LRDIMM memory types can NOT be mixed and matched on the
same motherboard.
