64GB DDR4 3200 ECC RDIMM for SuperMicro

This 64GB registered DIMM runs at DDR4 3200 with CL22 latency and ECC error correction. It is built for SuperMicro servers and workstations that require registered memory. The single-module design fills one slot and suits administrators upgrading capacity in compatible systems.

288-pin registered module with major OEM chips

The stick uses Samsung, Micron or Hynix components on a standard 288-pin DDR4 RDIMM PCB without a heat spreader. Registered buffering reduces electrical load on the memory controller, allowing stable operation in multi-DIMM server boards. Installation follows normal DIMM alignment; no extra cables or brackets are needed.

1.2V operation keeps power draw low

At 1.20V the module draws minimal power for its density, helping system thermals in dense chassis. Passive cooling relies on chassis airflow across the bare PCB. Acoustic impact is negligible because the memory adds no moving parts.

Questions about this item

Does this DDR4 3200 module run at the full PC4-25600 data rate in a SuperMicro server?

Yes, the module is rated DDR4 3200 PC4-25600 and will operate at that transfer rate when the platform memory controller is configured for 3200 MT/s.

Will the 288-pin RDIMM fit a standard SuperMicro DDR4 DIMM slot without a heat spreader?

The module uses the standard 288-pin DDR4 RDIMM form factor and has no heat spreader, so it fits any SuperMicro DDR4 registered DIMM slot.

What is the correct sequence for seating this 2Rx4 ECC RDIMM so the register latches engage?

Align the notch with the slot key, press straight down until both side latches click, then verify the module sits evenly across the channel.
