Memory

The following processor bus frequencies are required for the system to run at the supported memory frequencies.

Memory Frequency

Required Processor Bus Frequency

 

 

266 MHz

400 MHz, 533 MHz, or 800 MHz

 

 

333 MHz

533 MHz or 800 MHz

 

 

400 MHz

800 MHz

 

 

If a memory frequency is paired with an unsupported processor bus frequency, the system will run at the highest supported memory speed. For example, if a 333 MHz DIMM is paired with a 400 MHz processor bus, the system will run at 266 MHz, the highest supported memory speed.

The system will not start if you install unsupported DIMMs.

DIMM Sockets

There are four DIMM sockets on the system board, with two sockets per channel. The sockets are labeled XMM1, XMM2, XMM3, and XMM4. Sockets XMM1 and XMM2 operate in memory channel A. Sockets XMM3 and XMM4 operate in memory channel B.

The system board shown below may be different from the one in your computer.
