Page 281 Intel-Based Systems Computers equipped with Intel-based processors come with double data rate synchronous dynamic random access memory (DDR-SDRAM) dual inline memory modules (DIMMs). The memory sockets on the system board can be populated with up to three or four industry-standard DIMMs depending on the model. These memory module slots are populated with at least one preinstalled memory module.
Page 282: Dimm Sockets
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.
Page 283 In any 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.
