Server-grade 64 GB DDR4 module

This 64 GB DDR4 3200 registered DIMM is built for SuperMicro servers and workstations that require ECC protection and registered signalling. The single-module design adds a full 64 GB in one slot, suited for IT professionals managing mission-critical workloads.

288-pin RDIMM with major OEM chips

The module uses Samsung, Micron or Hynix components assembled to a 288-pin RDIMM form factor without a heat spreader. Registered buffering and 2Rx4 organisation ensure signal integrity on dense motherboards, while the standard pin-out allows straightforward installation in compatible SuperMicro systems.

1.2 V operation at CL22 latency

Running at 1.20 V, the memory draws minimal power for its capacity and speed rating. CAS latency of 22 at 3200 MT/s delivers stable throughput for sustained server tasks, and the low-voltage design helps keep system thermals manageable under continuous load.
