64GB DDR4 3200 ECC RDIMM kit

This 64GB kit contains two 32GB registered DDR4 modules rated at 3200 MT/s with CL22 latency. It is built for ThinkMate and Supermicro servers that require ECC registered memory. The 2Rx4 organisation and 1.20V operation match the platform specifications. Buyers needing non-ECC or unbuffered DIMMs for desktop boards cannot use this kit.

DDR4 3200 registered interface limits

The DDR4 3200 standard caps transfer rate at 3200 MT/s and the registered buffer adds one cycle of command latency. ECC operation consumes one extra bit per byte for error correction, reducing usable bandwidth slightly. Systems that only support lower DDR4 speeds or lack registered DIMM support will not accept these modules.

64GB capacity for multi-threaded workloads

Two 32GB ranks provide 64GB total, sufficient for virtualisation hosts, database buffers and large dataset caching. The 2Rx4 density fits boards with limited slot counts while leaving room for future expansion if more slots are free. Workloads that exceed 64GB or require higher frequencies will outgrow this configuration.

Questions about this item

Should I choose the 64GB kit or buy single 32GB modules to reach the same capacity?

The 64GB kit supplies two matched 32GB modules (2 x 32GB) tested together for dual-channel operation, while single modules are not guaranteed to pair without timing mismatches.

What does the DDR4 3200 rating deliver once installed in a compatible ThinkMate or Supermicro server?

The modules run at 3200 MT/s with CL22 latency at 1.20V, providing PC4-25600 bandwidth for registered ECC workloads on supported platforms.

How does the 288-pin RDIMM interface limit usable speed or capacity on these systems?

The 288-pin DDR4 RDIMM form factor locks the kit to DDR4 slots; it cannot fit DDR5 boards, and registered signalling is required by the target ThinkMate and Supermicro servers.
