32GB DDR4 2400 ECC RDIMM for Supermicro servers

This 32GB module uses Samsung chips and carries Supermicro certification as MEM-DR432L-SL02-ER24. It runs at 2400MHz with CL17 latency at the standard 1.20V. Registered ECC design with 2Rx4 organisation targets enterprise workloads that demand error correction.

288-pin RDIMM form factor and registered buffer

The 288-pin RDIMM fits Supermicro platforms that require registered memory. Registered buffering reduces electrical load on the memory controller, allowing larger populations per channel. Samsung M393A4K40CB1-CRC components are tested to the vendor’s quality programme before shipment.

Upgrade from lower-capacity or non-ECC DDR4

Replacing smaller RDIMMs or unbuffered ECC modules adds 32GB per slot and brings registered ECC reliability to the platform. The jump is worth it when the workload exceeds current capacity or when the system board requires registered DIMMs for full memory support.

Questions about this item

What does the DDR4 2400 PC4-19200 rating mean for real-world throughput?

The module runs at 2400 MT/s with CL17 latency, delivering the standard DDR4 2400 data rate for registered ECC server platforms.

What physical slot and clearance does this 288-pin RDIMM require?

It fits a standard DDR4 288-pin RDIMM slot; the registered dual-rank 2Rx4 design uses 1.2 V and matches the Samsung M393A4K40CB1-CRC form factor.

What is the correct installation step that is often missed with registered ECC RDIMMs?

Align the module notch with the slot key, press firmly until both locking tabs click, then verify in BIOS that ECC and registered mode are active.
