Chapter 2: Hardware information

2.5.2 Memory configurations

You may install 64MB, 128MB, 256MB, 512MB, 1GB and 2GB DDR

DIMMs into the DIMM sockets using the memory configurations in this

section.

Important notes on memory configurations

Table 1 Recommended memory configurations

* Use only identical DDR DIMM pairs.

* For dual-channel configuration (3), you may:

Sockets

Mode DIMM_A1 DIMM_A2 DIMM_B1 DIMM_B2

Single-channel (1) — Populated — —

(2) Populated — — —

(3) Populated Populated — —

Dual-channel* (1) — Populated — Populated

(2) Populated — Populated —

(3) Populated Populated Populated Populated

• install identical DIMMs in all four sockets

• install identical DIMM pair in DIMM_A1 and DIMM_B1 (blue sockets)

and identical DIMM pair in DIMM_A2 and DIMM_B2 (black sockets)

1. Installing DDR DIMMs other than the recommended configurations

may cause memory sizing error or system boot failure. Use any of

the recommended configurations in Table 1.

2. In Dual-channel configurations, install only identical (the same type

and size) DDR DIMM pairs for each channel.

3. Always install DIMMs with the same CAS latency. For optimum

compatibility, it is recommended that you obtain memory modules

from the same vendor. See list of Qualified Vendors List on page

2-13.

4. When all four sockets are populated with 1GB DIMMs (total 4GB),

the system may detect only 3+GB (a little less than 4GB) due to

the Northbridge resource allocation.

5. It is recommended to use the black DIMM slots first.
