64 GB DDR5 RDIMM for server workloads

This 64 GB DDR5 module runs at 4800 MT/s with CL40 latency and 1.10 V operation. It is built as a registered DIMM with ECC and a 2Rx4 organisation using Hynix components. The part targets enterprise servers and workstations that require high-capacity error-correcting memory.

Verify DDR5 RDIMM slot support and ECC requirements

Before ordering, confirm that the platform accepts DDR5 registered DIMMs and enables ECC functionality. The module uses a 2Rx4 rank layout, so the memory controller must support that configuration. Check the qualified vendor list for the specific motherboard or server model to ensure compatibility.

Registered design and ECC maintain stability under

The registered buffer reduces electrical load on the memory bus, allowing sustained throughput in multi-DIMM configurations. ECC corrects single-bit errors in real time, preventing data corruption during long compute jobs. CL40 timing at 4800 MT/s delivers consistent latency for memory-bound server applications.

Questions about this item

What does the 64GB RDIMM module include and do I need extra parts to install it?

The module is a single 64GB DDR5 4800 RDIMM with ECC and registered buffering; it plugs directly into a compatible DDR5 server slot and requires no extra cables, brackets or cooling accessories.

How do I decide between the listed speed and latency figures for this module?

The module runs at DDR5 4800 (PC5 38400) with CL40 latency at 1.10V; choose it when your platform specifies 4800 MT/s registered ECC memory, as the speed and latency are fixed for this part number.

What does the DDR5 4800 rating mean for real server performance?

The 4800 MT/s transfer rate and CL40 timing deliver the bandwidth and error-corrected throughput expected of registered DDR5 server memory, supporting high-capacity workloads on platforms qualified for this speed grade.
