I got an HP Z440 workstation, and bought 8 32GB 2133MHz memory modules for it for a total 256GB (two of those: https://www.ebay.com/itm/234996243550). Also as requested got a memory cooling contraption, and updated BIOS to the latest version.

The system is supposed to run at RAM 2133MHz speed, and has Xeon E5-2690 V4 which is should supportsupports this memory speed.

When I install 2 or 4 modules, it indeed does, but after I add two more or go to all 8, the RAM speed drops to 1866MHz.

Any ideas what could be wrong?
