For memory expansion, the system board provides two dual inline memory module (DIMM) connectors and supports 133 MHz DIMMs in sizes of 64 MB, 125 MB, and 512 MB. 100 MHz DIMMs may be used in systems with a 100 MHz FSB.

The following information applies to system memory:

Synchronous dynamic random access memory (SDRAM) is standard.

The maximum height of memory modules is 6.35 cm (2.5 in.).

Only PC 100 and PC 133 industry-standard, gold-lead DIMMs are supported.

DIMM connectors do not support RAMBUS Inline Memory Modules (RIMMs).

The PC 300GL supports error-corrected code (ECC). A mix of nonparity types configures as nonparity.

BIOS sepcific auto-configure, auto-detect maximum system memory.

For information on the pin assignments for the memory modules connectors, see “System memory connector” on page 34.

The following table shows some possible configurations for the supported DIMMs.
