2-4 Installing DIMMs
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..
DIMM Installation
Insert the desired number of DIMMs into the memory slots, starting with 1.
DIMM #1A, #1B, then #2A and #2B.
Insert each DIMM module vertically into its slot. Gently press down on the 2.
DIMM module until it snaps into place in the slot. Repeat for all modules. Pay
attention to the notch along the bottom of the module to prevent inserting the
DIMM module incorrectly.
This motherboard supports both dual-rank and single-rank memory modules. 3.
For system memory to work properly, please use all dual-rank memory mod-
ules or use all single-rank memory modules on the same motherboard. Check
the Supermicro web site for other information.
Memory Support
The X7SB3/X7SB3-F supports up to 8 GB Unbuffered ECC/Non-ECC DDR2
800/667 MHz in 4 DIMMs. Populating memory slots of the same bank with a pair
(or pairs) of memory modules of the same size and same type
will result in two-
way Interleaved Memory which will improve memory performance. (See the table
below.)
Note 1 : Due to OS limitations, some operating systems may not show
more than 4 GB of memory.
Note 2 : Due to memory allocation to system devices, memory remaining
available for operational use will be reduced when 4 GB of RAM is used.

( Notes: i. DIMM slot# specified: DIMM slot to be populated; “---“: DIMM slot not to be
populated. ii. DDR2 ECC/Non-ECC Unbuffered 800 MHz/667 MHz DIMMs are supported;
however, please use the memory modules of the same speed and of the same type on a
motherboard. iii. For memory to work properly, you need to follow the restrictions listed
above. )
