2.5 Installing the Memory

Before installing memory, ensure that the memory you have is compatible with the
motherboard and processor. Only DDR2-667/533/400 Registered DIMM modules are
supported. Check the TYAN Web site at: www.tyan.com for details of the type of
memory recommended for your motherboard.
The following diagram shows common types of DDR2 memory modules.
All installed memory will automatically be detected and no jumpers or settings
need changing.
The M4985 supports up to 64GB of memory, S4985 + M4985 supports up to
128GB of memory.
Rules for populating memory :
64-bit support: Choose DIMM slots 0 or 2 by themselves or use 0 and 2 together for
every CPU socket that corresponds to those DIMM slots.
128-bit support: Choose DIMM slots 0 and 1 or 2 and 3 or all 4 together for every
CPU socket that corresponds to those DIMM slots.
NOTE : Please always install memory beginning with CPU4DIMM0 or CPU4DIMM2. You
can choose to install single, dual or four memory modules.
