POWER9 Hardware Compatibility List/Memory

Compatibility rules

The criteria for compatibility are essentially:

• must be DDR4;
• must be ECC;
• must be registered (RDIMM);
• must NOT be LRDIMM.

The supported module sizes are 8GB, 16GB, 32GB, 64GB and 128GB. 4GB is expected to work (and is reported working by at least 1 user) but is not officially supported by Raptor.

The supported memory speeds are 1600, 1866, 2133, 2400, 2666 MHz.

Ram will be running at a potentially slower frequency (2666, 2400, or 2133) based on if there is 1, 2 or 4 DIMMs per channel

Platform	Slots	Max. Capacity
Talos II	Up to two sockets, each of 4 channels of 2 slots each	2TiB
Blackbird	Two channels, one slot each	256GiB

Incompatible memory

NOTE: Memory may be removed from this table after firmware support has been added, or there may be a fundamental hardware incompatibility. If you have incompatible memory listed in the table below, you may want to bookmark and check this page from time to time to see if a firmware update has resolved the issue.
