MB, 512MB or 1GB DIMMs (Dual In-line Memory Modules)
with the ECC (Error Correction Control), which operate at a sys-
tem bus clock frequency of 200 MHz.
See “Specifications” on page 252.
The memory can be expanded to a maximum of 4GB by installing
additional memory modules with up to two different capacities.
When installing additional memory modules, add two modules
with same capacities at a time.
The memory controller is conformable to the DDR SDRAM.
When installing additional memory modules, start from the slot
1A and 1B first, the slot 2A and slot 2B last.
When installing memory modules with different capacities, insert
them in the slots 1A/1B to 2A/2B in order of increasing capacity,
that is, the memory module with the smallest capacity in the slot
1A and 1B.
