64GB DDR4 2666 Kit for Supermicro Workstations

This 64GB kit contains two 32GB DDR4 2666 UDIMM modules built for Supermicro desktop and SuperWorkstation boards such as the MBD-C9Z390-CG. It targets IT professionals and enthusiasts who need reliable, high-capacity memory for demanding workloads on validated platforms.

Sustained Load Behaviour at CL19 1.20V

Modules run at 2666 MT/s with CL19 timings and a standard 1.20V supply. The 2Rx8 organisation using major OEM Samsung, Micron or Hynix chips is stress-tested under load to maintain stability during extended compute or virtualisation tasks without a heat spreader.

Verify Board Slots and Memory Type Before Ordering

Confirm your motherboard accepts 288-pin DDR4 UDIMM modules and supports non-ECC unbuffered operation at this speed and rank configuration. The kit is not suitable for systems requiring ECC, registered DIMMs or a different DDR generation.

Questions about this item

How much power does this 1.20V DDR4 kit draw under sustained load?

The modules run at 1.20 V, the standard DDR4 voltage, so power draw stays within normal desktop limits during all-day operation.

Does my motherboard need four slots or will two slots accept this 2x32GB kit?

The kit contains two 32 GB UDIMMs, so a board with two free 288-pin DDR4 slots is sufficient.

Can I keep my existing DDR4 modules and add this CL19 2666 kit?

Mixing kits is possible if the board supports the same DDR4 voltage and speed, but matching capacity and timings gives the most stable result.
