Memory Support

The X9DA7/X9DAi supports up to 512 GB of registered/unbuffered load reducing ECC DDR3-1600/1333/1066/833 memory in 16 DIMM slots. For the latest memory updates, please refer to the product page on the Supermicro website.

Order of Populating DIMM Slots

For memory to work properly, follow the table below for the correct order of populat- ing the DIMM slots. See the serverboad layout page for slot numbering.

Notes: an "X" indicates a slot populated with a memory module.

Populate the "A" DIMM slots first. Any of the slots may be used. Populate the "B" slots only after all "A" slots have been filled.
