2. Both FBD 533 MHz and 667 MHz DIMMs are supported; however, you need to use the
memory modules of the same speed and of the same type on a Motherboard
3. Interleaving memory is supported when pairs of DIMM modules are installed. To
optimize memory performance, please install pairs of memory in both Branch 1 and
Branch 2
4. For memory to work properly, you need to follow the restrictions listed above.
