Chapter 2: Installation
2-7
Notes:
Due to OS limitations, some operating systems may not show more than 4 1.
GB of memory.
This motherboard supports both dual-rank and single-rank memory modules. 2.
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.
Due to memory allocation to system devices, memory remaining available 3.
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 Avail-
ability Table for details.
2-4 Installing DIMMs
Warning! 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 Memory Support below.)
DIMM Installation
Insert a desired number of modules into slots. (A minimum of two modules is re-
quired.) Gently press down on a module until it snaps into place in the slot. The
memory scheme is interleaved, so you must install two modules at a time, beginning
with DIMM 1A and DIMM 1B, DIMM 2A and DIMM 2B, then DIMM 3A, DIMM 3B.
Memory Support
The X7DCT-L/X7DCT-LF/X7DCT-3/X7DCT-3F/X7DCT-3IBXF supports up to 48
GB ECC Registered DDR2 667/533 in 6 DIMMs. Populating memory slots of the
same bank with a pair 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.

6DIMMs DIMM1A DIMM2A DIMM3A DIMM1B DIMM2B DIMM3B
( Notes: i. DIMM slot# specified: DIMM slot to be populated; “---“: DIMM slot not to be
populated. ii. Both 533 MHz and 667MHz DIMMs are supported; however, you need to 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. )
