Server Memory Upgrade

This 64GB DDR5 4800 ECC RDIMM module is built for Samsung-compatible servers and workstations that require registered memory with error correction. It suits IT professionals who need dependable capacity for virtualisation, database or compute workloads.

Replacing Lower-Capacity RDIMMs

The jump is worth it when existing 32GB or smaller registered modules leave headroom unused and the platform supports 2Rx4 organisation at 1.10V. Swapping to this single 64GB stick consolidates slots and raises total memory without mixing ranks.

Build Integration

The 288-pin DDR5 RDIMM fits registered DIMM slots on qualified Samsung motherboards; the board and CPU must support ECC registered operation at 4800MT/s. No heat spreader is included, so chassis airflow must handle bare modules under sustained load.

Questions about this item

Does the 288-pin DDR5 RDIMM fit a standard server DIMM slot?

Yes, the 288-pin DDR5 RDIMM form factor matches standard server DIMM slots that accept registered memory.

What BIOS setting is often missed when installing this ECC registered module?

Enable ECC and registered memory support in the BIOS after seating the module, otherwise the system may not recognise the 64GB capacity.

When should the 1.10V DDR5 module be replaced in a 24/7 server?

Replace if memory diagnostics report uncorrectable ECC errors or the server logs repeated corrected errors over time.
