Supermicro Certified DDR5 4800 RDIMM

This 64GB registered DIMM carries Supermicro certification and uses Samsung DDR5 chips rated at 4800 MT/s with CL40 latency. It operates at the standard 1.10V and provides native ECC with a 2Rx4 dual-rank layout on a 288-pin form factor.

For servers needing registered ECC memory

Suited for Supermicro platforms that require certified registered ECC RDIMMs and can run DDR5 4800 modules. Not suited for desktop boards that only accept unbuffered non-ECC memory or platforms that do not support registered DIMMs or DDR5 native ECC.

2Rx4 dual-rank registered ECC

The module is built as 2Rx4 EC8 dual-rank registered ECC, which determines electrical loading and error-correction behaviour on the memory bus. Verify that your system's qualified vendor list includes this exact rank and ECC configuration before purchase.

Questions about this item

Will this 288-pin RDIMM fit in my server's DDR5 memory slots?

Yes, the module uses the standard 288-pin RDIMM form factor for DDR5 4800 systems. Verify your motherboard supports 64GB registered DIMMs before installing.

How do I install this Supermicro certified module, and what step is often missed?

Power down, open the chassis, align the notch on the 288-pin edge connector with the slot key, press firmly until both retention clips click. The step often missed is confirming the BIOS recognises the full 64GB at 4800MHz after first boot.

When will this Samsung-based ECC RDIMM need replacement or maintenance?

The module has no moving parts and requires no scheduled maintenance. Replace only if memory diagnostics report uncorrectable ECC errors or the server fails to POST with this DIMM installed.
