DIMM sockets. The Motherboard supports the following memory features:
•
240-pin DIMMs with gold-plated contacts.
•
ECC
(72-bit).
•
DDR2 533/667 MHz Memory speeds
•

6. 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
7. 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
8. For memory to work properly, you need to follow the restrictions listed above.
