Chapter 2: Installation

3.Gently press down on the memory module until it snaps into place.

4.With two CPUs installed, repeat step 2 to populate the CPU2 DIMM slots. Always install pairs of DIMMs to both CPU DIMM slots for more efficient operation.

Note: 256 MB, 512 MB, 1 GB, 2 GB, 4 GB and 8 GB memory modules are sup- ported. 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 H8QI6/i-F serverboard.

Support

The H8QI6/i-F serverboard supports single or dual-channel, DDR2-800/667/533/400 registered ECC SDRAM. Only interleaved memory is supported, so you must popu- late 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 pos- sible updates to this limitation.

Maximum Memory

128GB of DDR2-800/667/533/400 registered ECC SDRAM.

Note the notch in the slot and on the bottom of the DIMM.

These prevent the DIMM from being installed incorrectly.

To Remove:

Use your thumbs to gently push each re- lease tab outward to release the DIMM from the slot.
