64GB DDR4 kit for Supermicro workstations

This 64GB kit contains two 32GB DDR4 UDIMM modules rated at 2933MHz with CL21 latency. It is built for Supermicro desktop and SuperWorkstation motherboards such as the MBD-C9Z490-PG. The non-ECC unbuffered design suits systems that do not require error-correcting memory.

Low-voltage operation at 1.2V

Each module runs at 1.20V, matching the standard DDR4 voltage for reduced power draw and heat. Without a heat spreader the sticks rely on case airflow, so a chassis with steady air movement keeps temperatures in check. The unbuffered layout adds no extra electrical load to the memory controller.

Two 288-pin slots required

Installation needs two free 288-pin DDR4 slots on a compatible Supermicro board. The 2Rx8 organisation works with the platform's memory topology without registered buffering. Builders who need ECC protection or registered modules must choose a different kit, as this product provides neither.

Questions about this item

How do I install the 288-pin DDR4 UDIMM modules in a Supermicro motherboard, and what step is often missed?

Align the notch on each 32GB module with the slot key, press down evenly until both side clips click shut, then verify in BIOS that both sticks report 2933 MHz at CL21 1.20 V.

What maintenance or replacement will the 2Rx8 unbuffered DIMMs need over time?

No scheduled maintenance is required; if a module fails the lifetime replacement warranty covers it, otherwise the kit runs until a system upgrade makes the DDR4 2933 specification obsolete.

What limit appears first when the 64GB kit runs sustained workloads at 23400 MT/s?

The CL21 latency at 1.20 V is the first bottleneck; thermal throttling is unlikely without a heat spreader, but bandwidth saturates before temperature becomes an issue.
