Buffered DIMM) memory modules.
ECC with memory scrubbing and with the Single Device Data Correction
(SDDC) function is supported.

Module population
–
The memory modules have to be registered Fully Buffered DIMMs (ECC
DDR2 533/667).
–
The memory modules have to be populated in pairs.
–
Each pair must consist of identical memory modules.
–
Each memory bank and channel (module) must be equipped with 2 memory
modules.
–
The module capacity between pairs can differ: pair 1A/1B can be populated
with two 512 Mbyte modules and pair 2A/2B with two 1 Gbyte modules.
