Memory 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.

For example, if the system is populated with a DIMM that is 333 MHz and a second DIMM that is 400 MHz, the system will run at the slower of the two speeds. ■ In dual channel mode, the DIMM pairs must be identically matched. DIMMs in the XMM1 and XMM3 black sockets must be identical; DIMMs in the XMM2 and XMM4 blue sockets must also be identical. Therefore, if you have one preinstalled DIMM in socket XMM1 and are adding a second DIMM, it is recommended that you install an identical DIMM into the XMM3 socket. ■ In dual channel mode, the DIMM pairs must be identically matched. DIMMs in the XMM1 and XMM3 black sockets must be identical; DIMMs in the XMM2 and XMM4 blue sockets must also be identical. Therefore, if you have one preinstalled DIMM in socket XMM1 and are adding a second DIMM, it is recommended that you install an identical DIMM into the XMM3 socket. If you are populating all four DIMM sockets, use identical DIMMS in each socket. Otherwise, the system will not operate in dual channel mode. F-2 Service and Technical Reference Guide, xw3100

Memory

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 will automatically operate in single channel mode or a higher-performing dual

channel mode, depending on how the DIMMs are installed.

■

In single channel mode, the maximum operational speed is determined by the slowest DIMM

in the system. For example, if the system is populated with a DIMM that is 333 MHz and a

second DIMM that is 400 MHz, the system will run at the slower of the two speeds.

■

In dual channel mode, the DIMM pairs must be identically matched. DIMMs in the XMM1

and XMM3 black sockets must be identical; DIMMs in the XMM2 and XMM4 blue sockets

must also be identical. Therefore, if you have one preinstalled DIMM in socket XMM1 and

are adding a second DIMM, it is recommended that you install an identical DIMM into the

XMM3 socket.

■

In dual channel mode, the DIMM pairs must be identically matched. DIMMs in the XMM1

and XMM3 black sockets must be identical; DIMMs in the XMM2 and XMM4 blue sockets

must also be identical. Therefore, if you have one preinstalled DIMM in socket XMM1 and

are adding a second DIMM, it is recommended that you install an identical DIMM into the

XMM3 socket. If you are populating all four DIMM sockets, use identical DIMMS in each

socket. Otherwise, the system will not operate in dual channel mode.
