2.3.2 Memory

Memory may be added to or removed from the AlphaServer DS20L.

Each memory bank has four slots that accept 168-pin PC100 SDRAM PLL
registered/buffered based SPD DIMMs. Memory is supported in a size range
from 512 MB to 2 GB.

There are two DIMM banks designated Bank 0 and Bank 1. The slots are
arranged in an alternating pattern. See Figure 2-5.

2.3.2.1 Memory Configuration Rules

A bank must be fully populated; that is, all four slots in a given bank (0 or 1)
must be filled.

Bank 0 must be populated first.

A bank must use the same type, size, and speed DIMMs. Bank 0 and Bank
1 may have different type, size, and speed of DIMMs from each other,
however.
