Upgrading main memory

The slots for the main memory are suitable for 256, 512, 1024 and 2048 Mbyte DDR-DIMM memory
modules. The organisation in three memory banks 0 to 2 enables fast memory access with
interleave. The board supports a maximum of 12 Gbytes.
The memory module banks must be populated in pairs with identical memory modules. Begin with
bank 2A/2B, followed by bank 1A/1B, then bank 0A/0B. This is absolutely required by technical
reasons.
If single (S) and double side (D) memory modules are mixed, only this placements are allowed:
You may only use registered DDR DIMM memory modules. Unbuffered memory modules
!
are not permitted.
DDR DIMM memory modules must be designed for a clock frequency of 266 MHz (meets
PC2100 specification).
