Unbuffered DIMMs of the following sizes: 16 MB, 32 MB, 64 MB, 128 MB and 256 MB for a total memory size of 1 GB.

Registered DIMMs of the following sizes: 64MB, 128Mb and 256MB for a maximum memory size of 1 GB. Only non-stacked DIMMs are supported because of a server board space constraint.

When ECC memory is installed, the BIOS supports both ECC and non-ECC mode. ECC mode is enabled in the BIOS Setup program. The BIOS automatically detects if ECC memory is installed and provides the Setup option for selecting the ECC mode. If any non-ECC memory is installed, the Setup option for ECC mode does not appear and ECC operation is not available.

Table 4 describes the effect of using Setup to put each memory type in each supported mode.
