Place DIMMs in "X" location. 2. DIMM population must correspond to the above tables. 3. DIMM modules support 1 GB, 2 GB, 4 GB and 8 GB DIMMS. 4. The size of each DIMM must be the same across the configuration. 5. Do not mix UDIMMs with RDIMMs. Memory identification Generally, there are some memory information printed on the label of the DIMM module. Different vendors may have different formats but the convention is usually like this: Density Rank Bit organization Speed Item Density Rank Bit Organization Speed Description 1GB, 2GB, 4GB, 8GB. Intel Xeon Processor 5500 Series CPU supports DIMM organized by 1Gb or 2Gb DRAM chips. 1R = Single Rank 2R = Dual Rank 4R = Quad Rank Note: If quad rank DIMM is used, a maximum of only two DIMMs per channel can be supported. This platform supports x4 and x8. Note: It is not recommend to mix DIMMs with different bit organizations in one system. PC3 - 6400 => DDR3- 800 PC3 - 8500 => DDR3- 1066 PC3 - 10600 => DDR3- 1333 PC3 - 12800 => DDR3- 1600 Memory installation WARNING:Memory of the identical size, speed, and organization must be installed in the same colored DIMM slots. Follow these steps: 1. Power down the server and unplug the power cord. 2. Remove the air shroud (see "Removing the air shroud" on page 46). 3. Locate the DIMM slot on the mainboard. 54 Chapter 7
