2-4 Installing DIMMs
Note: Check the Super Micro web site for recommended memory modules.
CAUTION
Exercise extreme care when installing or removing DIMM modules to prevent any possible damage. Also note that the memory is interleaved to improve performance (See step 1).
DIMM Installation
1.Insert the desired number of DIMMs into the memory slots, starting with DIMM1A. The memory scheme is interleaved so you must install two modules at a time, beginning with DIMM1A, DIMM1B, then, DIMM2A and DIMM2B
2.Insert each DIMM module vertically into its slot. Pay attention to the notch along the bottom of the module to prevent inserting the DIMM module incorrectly.
3.Gently press down on the DIMM module until it snaps into place in the slot. Repeat for all modules (See step 1 above).
Memory Support
The C2SBA+II/C2SBA+/C2SBA/C2SBE supports up to 8 GB Unbuffered Non- ECC DDR2 800/677 MHz in 4 DIMMs. Populating DIMM#1A,DIMM#1B, and/or DIMM#2A, DIMM#2B with memory modules of the same size and of the same type will result in dual channel,
Notes:
1.Due to the OS limitations, some operating systems may not show more than 4 GB of memory.
2.Both Unbuffered ECC and
3.Due to memory allocation to system devices, memory remaining available for operational use will be reduced when 4 GB of RAM is used. The reduction in memory availability is disproportional. (Refer to the following Memory Availability Table for details.) For Microsoft Windows users: Microsoft imple- mented a design change in Windows XP with Service Pack 2 (SP2) and
Windows Vista. This change is specific to the Physical Address Extension
(PAE) mode behavior which improves driver compatibility. For more informa- tion, please read the following article at Microsoft’s Knowledge Base website at: http://support.microsoft.com/kb/888137.
