Installing Memory
Insert each memory module vertically into its slot, paying attention to the
1.
notch along the bottom of the module to prevent inserting the module
incorrectly (see Figure 2-1).
Install to slots CPU1/DIMM1A and CPU1/DIMM1B fi rst, then to CPU1/
2.
DIMM2A and CPU1/DIMM2B, etc. Always install in pairs and in the numerical
order of the DIMM slots. See support information below.
Gently press down on the memory module until it snaps into place.
3.
With two CPUs installed, repeat step 2 to populate the CPU2 DIMM slots.
4.
Always install pairs of DIMMs to both CPU DIMM slots for more effi cient
operation.
Note:
256 MB, 512 MB, 1 GB, 2 GB, 4 GB and 8 GB memory modules are
supported. It is highly recommended that you remove the power cord from the
system before installing or changing memory modules. Please refer to our web site
for memory that has been tested on the H8DA6+/I+(-F) serverboard.
Support
The H8DA6+/I+(-F) supports single or dual-channel, DDR2-667/533/400 registered
ECC SDRAM. Only interleaved memory is supported, so you must populate two
DIMM slots at a time (see procedure above).
Populating two adjacent slots at a time with memory modules of the same size and
type will result in interleaved (128-bit) memory, which is faster than non-interleaved
(64-bit) memory.
Note:
Due to a CPU limitation, fully populating DIMM slots with
DDR2-667 will pull the speed down to 533 MHz. Please see our web site for possible
updates to this limitation.
Maximum Memory
The H8DA6+/I+(-F) supports a maximum of 128 GB of DDR2-800/667/533
registered ECC SDRAM.
Exercise extreme caution when installing or removing memory
modules to prevent any possible damage.
