Hardware Installation
The integrated memory controller in AMD's 64-bit Socket 939
series CPU will directly catch data transmission from DDR RAM
without passing through the Northbridge. Therefore when using 4
identical double side DIMMs or using 2 DIMMs in non-dual channels,
the memory speed will reduce to DDR333. Please refer to the
detailed memory speed shown below.

A DIMM's SPD is originally fixed at 1T. When modules are inserted
in DIMM 1 and DIMM 3, the SPD must be 2T for better system
stability. We recommend inserting DIMMs in DIMM 2 and DIMM 4.
"S": Single side DIMM
"D": Double side DIMM
