64 GB DDR4 Kit for Supermicro Workstations

This 64 GB kit contains four 16 GB DDR4 UDIMM modules rated at 2933 MHz with CL21 latency. It is built for Supermicro desktop and SuperWorkstation motherboards such as the MBD-C9X299-PGF. The non-ECC unbuffered design suits standard workstation workloads.

Unbuffered 288-Pin Modules at 1.2 V

Each stick uses a 288-pin DDR4 UDIMM form factor and runs at 1.20 V without a heat spreader. The 1Rx8 organisation fits directly into four standard DIMM slots, leaving no need for registered memory support or additional cooling clearance.

Four-Rank Kit for 64 GB Total Capacity

The four single-rank modules provide 64 GB of system memory for multi-threaded applications and virtual machines. Systems requiring ECC protection, registered DIMMs or capacities beyond 64 GB will need a different memory configuration.

Questions about this item

What is the CAS latency of these modules?

The kit runs at CL21 latency as specified for the DDR4 2933 speed grade.

How much heat do four sticks generate under continuous load?

These modules have no heat spreader and operate at the standard 1.2 V DDR4 voltage, so thermal output is low for typical workloads.

Does my motherboard need to support unbuffered non-ECC DDR4 UDIMMs?

Yes, the kit is 288-pin DDR4 UDIMM, non-ECC and unbuffered, so the board must accept that exact module type.
