The following processor bus frequencies are required for the system to run at the supported
memory frequencies.
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 may differ from the one in your product.
