Notes: 1. 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:
Item
Description
Density
1GB, 2GB, 4GB, 8GB.
Intel Xeon Processor 5500 Series CPU supports DIMM organized by 1Gb or 2Gb DRAM chips.
Rank
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.
Bit Organization
This platform supports x4 and x8.
Note: It is not recommend to mix DIMMs with different bit organizations in one system.
Speed
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.
