Installing Memory

Note: Check the Supermicro web site for recommended memory modules.
Exercise extreme care when installing or removing DIMM modules
Installing DIMMs
1. Insert the desired number of DIMMs into the memory slots, starting with slot
P1-DIMM1A. For best performance, install memory modules of the same type
and same speed in the slots as indicated in the tables below.
2. Insert each DIMM vertically into its slot. Pay attention to the notch along the
bottom of the module to prevent inserting the DIMM module incorrectly (see
Figure 5-5).
3. Gently press down on the DIMM module until it snaps into place in the slot.
Repeat for all modules
Memory Support
The X8DTU-F supports up to 96 GB of registered ECC DDR3-1333/1066/800
SDRAM in 12 slots. (RDIMM modules are supported.)
Notes: Memory speed support depends on the type of CPU used. Due to OS limita-
tions, some operating systems may not show more than 4 GB of memory. Due to
