2-4 Memory Installation
Note: Check the Supermicro website 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
Insert the desired number of DIMMs into the memory slots, starting with 1.
DIMM #P1-DIMM1A. When populating DIMM modules always start with Chan-
nel1 (#P1-DIMM1A and 1B) fi rst. For optimal memory performance, please
use memory modules of the same type and the same speed on the mother-
board. (See the Memory Installation Table Below.)
Insert each DIMM module vertically into its slot. Pay attention to the notch 2.
along the bottom of the module to prevent inserting the DIMM module incor-
rectly.
Gently press down on the DIMM module until it snaps into place in the slot. 3.
Repeat for all modules.
Memory Support
The X8DTH-6/X8DTH-6F/X8DTH-i/X8DTH-iF supports up to 96 GB of Registered
ECC or 24 GB of Unbuffered ECC/Non-ECC DDR3 1333/1066/800 MHz Memory
in 12 DIMMs.
