Intel SE440BX-2 Product Guide - Page 30

Installing and Replacing Motherboard Components CAUTION To be fully compliant with all applicable Intel® SDRAM memory specifications, the motherboard should be populated with DIMMs that support the Serial Presence Detect (SPD) data structure. If your memory modules do not support SPD, you will see a notification to this effect on the screen at power up. The BIOS will attempt to configure the memory controller for normal operation. However, DIMMs may not function under the determined frequency. You can access the PC Serial Presence Detect Specification at: http://www.intel.com/design/pcisets/memory/  NOTE All memory components and DIMMs used with the SE440BX-2 motherboard must comply with the PC SDRAM specifications. These include: the PC SDRAM Specification (memory component specific), the PC100 SDRAM Component Testing Summary, the PC Unbuffered DIMM Specification, and the PC Registered DIMM Specification. You can access these documents through the Internet at: http://www.intel.com/design/pcisets/memory/ Figure 12 shows the location of the DIMM sockets. 0 1 2 OM07171 Figure 12.
