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
