  • CL17 latency at 1.2V balances performance and efficiency
  • Validated for five Supermicro A2SDi motherboard models

Purpose-Built Server Memory

This 32GB DDR4 ECC Registered RDIMM is designed for Supermicro motherboards including the A2SDi-12C-HLN4F, A2SDi-H-TF, A2SDV-4C-LN10PF, A2SDi-4C-HLN4F and A2SDi-8C+-HLN4F. It targets administrators upgrading workstations, servers or NAS systems that require registered error-correcting memory.

Verify Platform Compatibility

Confirm your motherboard is one of the five listed Supermicro models before ordering. This module uses 288-pin DDR4 registered technology and will not function in standard desktop computers or alongside unbuffered memory. The system must support ECC Registered DIMMs at 1.2V.

Steady-State Reliability

Rated at 2400MHz with CL17 latency, the module maintains data integrity through ECC correction during continuous operation. Registered buffering reduces electrical load on the memory controller, helping sustain stability in multi-DIMM configurations under prolonged workloads.

Questions about this item

Does the module ship with any accessories or mounting hardware, or must I buy those separately?

The box contains only the 32 GB 288-pin DDR4 ECC Registered RDIMM; no extra brackets, screws or cables are included and none are required for installation.

How do I know whether this 32 GB DDR4 2400 CL17 1.2 V 2Rx4 RDIMM is the right capacity and rank for my Supermicro A2SDi board?

The part number 2R4D42R432GB matches Supermicro MEM-DR432LC-ER24 and its variants, so this single 32 GB dual-rank module is the direct replacement for those motherboards.

What does the 2400 MHz PC4-19200 rating mean once the DIMM is installed in a compatible server?

The module will run at 2400 MT/s with CL17 latency at 1.2 V, delivering the rated PC4-19200 bandwidth for ECC Registered workloads on the listed Supermicro platforms.
