16 GB DDR5-4800 ECC RDIMM for ASUS servers

This 16 GB DDR5 module runs at 4800 MT/s with CL40 latency and 1.10 V operation. It uses a 288-pin registered DIMM format with on-die ECC and a single 1Rx8 rank. The part is validated for the ASUS RS700-E11-RS4U 1U dual-socket platform.

Who this suits and who should look elsewhere

IT teams expanding memory in the named ASUS 1U server will find direct compatibility and registered buffering for multi-DIMM stability. Buyers needing non-ECC unbuffered DIMMs for workstations or consumer boards cannot use this module. Systems requiring a different DDR5 speed, voltage or pin count must select another part.

The spec that decides fit

Registered ECC RDIMM with 288-pin DDR5 interface is the single requirement the host platform must support. If the server manual specifies registered ECC DDR5 RDIMMs this module will install; if it calls for unbuffered UDIMMs or a different generation it will not.

Questions about this item

Does the 288-pin DDR5 RDIMM fit the ASUS RS700-E11-RS4U 1U server memory slots?

Yes, the module is a 288-pin DDR5 RDIMM built for the ASUS RS700-E11-RS4U 1U dual-socket server.

What is the correct way to seat this registered ECC module so the server recognises all 16 GB?

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, then power on and verify 16 GB in BIOS.

When should the 1.1 V DDR5 4800 CL40 RDIMM be replaced in a production server?

Replace the module if memory diagnostics report uncorrectable ECC errors, the system logs repeated corrected errors, or the server fails to POST with this DIMM installed.
