  • 64 GB capacity supports memory-intensive server workloads
  • DDR4 3200 speed delivers high data throughput for demanding applications
  • ECC registered design detects and corrects errors to protect data integrity
  • CL22 22-22-22 timing provides low-latency access to critical data
  • 20 V operation reduces power draw in dense memory configurations

64 GB DDR4 server module

The Kingston KSM32RD4/64SC is a 64 GB DDR4 SDRAM DIMM built for servers and workstations that require registered ECC memory. It runs at 3200 MHz with CL22 latency and operates at 1.20 V. The dual-rank 2Rx4 organisation and 288-pin interface suit high-density configurations.

Upgrade from non-ECC or lower-capacity sticks

This module replaces unbuffered consumer memory or smaller registered DIMMs when data integrity and capacity take priority. The jump is worth it when workloads demand error correction and densities beyond 32 GB per slot. Registered signalling helps maintain stability as the memory subsystem scales.

Fits registered DDR4 platforms

The DIMM fits 288-pin DDR4 slots that support registered ECC operation at 1.20 V. It frees board space by delivering 64 GB in a single slot, reducing the number of populated channels. The module is not for systems that only accept unbuffered memory or that cannot address dual-rank registered modules.

Questions about this item

Does the 288-pin DDR4 DIMM fit a standard server memory slot?

Yes, the module uses the 288-pin DDR4 DIMM form factor that matches standard server DDR4 slots.

How do I install the 64 GB registered ECC module correctly?

Align the notch on the 288-pin edge connector with the slot key, press firmly until both retention clips click, and ensure the motherboard supports registered ECC memory.

When should I replace this 3200 MHz CL22 kit?

Replace it only if memory diagnostics report uncorrectable ECC errors or the system becomes unstable; otherwise the module has no scheduled replacement interval.
