CAUTION! Exercise extreme care when installing or removing DIMM modules to
prevent any possible damage.

Memory Support

The H8DGU-F supports up to 512 GB of DDR3-1333/1066/800MHz registered
ECC SDRAM or 128 GB of DDR3-1333/1066/800 MHz unbuffered ECC/non-ECC
SDRAM in 16 DIMM slots. See the following table for memory installation.
Memory speed support is dependent on the type of CPU used on the board.
Installing Memory Modules
1. Insert the desired number of DIMMs into the memory slots, starting with
DIMM 1A. For best memory performance, please install memory modules
of the same type and same speed on the memory slots as indicated on the
tables below.
2. Insert each DIMM module vertically into its slot. Pay attention to the notch
along the bottom of the module to avoid installing incorrectly (see Figure 5-3).
3. Gently press down on the DIMM module until it snaps into place in the slot.
Repeat for all modules.
To Install: Insert
module vertically and
press down until it
snaps into place. Pay
attention to the align-
ment notch at the
bottom.
To Remove: Use
your thumbs to gen-
tly push the release
tabs near both ends
of the module. This
should release it from
the slot.
