Capacity and purpose

This is a 64GB DDR5 5600 ECC RDIMM module built for server and workstation systems. The registered design and 2Rx4 organisation suit multi-socket boards that require error correction and signal buffering.

Compatibility checks

Verify that your platform accepts DDR5 RDIMM modules at 5600 MT/s with CL40 timing and 1.10 V operation. Confirm the motherboard supports 288-pin DIMM slots and the 2Rx4 rank structure before ordering.

Thermals noise and power

Standard DDR5 voltage of 1.10 V keeps power draw low during typical workloads. The module runs passively without a fan so acoustic output is negligible inside a server chassis.

Questions about this item

Does the 64GB DDR5 5600 module ship alone or as a kit, and are any brackets or cables required for installation?

The listing describes a single 64GB module (1 x 64GB). No extra brackets or cables are mentioned; the DIMM installs directly into a standard 288-pin DDR5 server slot.

Should I choose the 5600MHz PC5-44800 CL40 version or a different speed grade for my HP server?

This module is built to match the HP N69683-001 specification at DDR5 5600 (PC5-44800) with CL40 latency and 1.10V. Select this exact speed grade to maintain the server's qualified memory profile.

What does the 5600MHz rating deliver once the RDIMM is seated in a compatible HP system?

At DDR5 5600 the module transfers data at up to 44800 MT/s per pin. The registered 2Rx4 ECC design buffers address and command signals, allowing the memory controller to sustain that bandwidth across the full 64GB capacity while correcting single-bit errors.
