Supermicro Certified 64GB DDR4 RDIMM

This Supermicro certified module delivers 64GB of DDR4 3200 registered ECC memory in a single 288-pin RDIMM. It operates at 1.20V with CL22 latency and uses Samsung 2Rx4 chips for stable server operation. The module is validated for Supermicro platforms requiring registered error-correcting memory.

Suited for capacity-focused server upgrades

Administrators expanding memory in compatible Supermicro systems gain a high-density 64GB stick that fills one slot. Builds needing unbuffered UDIMMs, non-ECC memory, or speeds beyond DDR4 3200 cannot use this registered module. Systems limited to lower maximum module densities should verify support before ordering.

Fits registered DDR4 288-pin server boards

The RDIMM installs in standard 288-pin DDR4 slots wired for registered ECC operation at 1.20V. It frees additional DIMM slots for further expansion while providing 64GB per module. Compatibility depends on the motherboard qualified-vendor list and maximum supported capacity per slot.

Questions sur cet article

What motherboard slot and memory standard does this 64GB DDR4 3200 288-pin RDIMM require?

This module fits a standard DDR4 288-pin RDIMM slot running at 1.20V; the platform must support registered ECC memory and the PC4-25600 speed grade.

How will this CL22 2Rx4 Samsung module behave if installed alongside slower DDR4 RDIMMs already in the server?

The memory controller will down-clock all populated channels to the lowest common speed and tightest latency, so existing slower RDIMMs will set the pace for this 3200 MHz stick.

Which BIOS indicators confirm this Supermicro-certified MEM-DR464MC-ER32 is operating at its rated 3200 MT/s with ECC active?

Check the POST memory summary or BIOS setup: it should show 64GB per module, 3200 MT/s, dual-rank 2Rx4 organisation, ECC enabled and voltage at 1.20V.
