Server DDR5 RDIMM Kit

This 128 GB registered ECC kit contains two 64 GB DDR5 4800 modules built for servers and workstations that require registered memory. The dual-rank design uses 1.10 V operation and CL40 timing to deliver stable throughput in multi-socket platforms.

Compatibility guidance

It suits administrators upgrading DDR5-ready servers that accept 288-pin RDIMMs with ECC and registered buffering. Buyers whose systems only support unbuffered UDIMMs, non-ECC memory, or earlier DDR generations cannot use these modules.

Deciding specification

The registered ECC RDIMM form factor is the single attribute that determines fit; the memory controller must explicitly support registered DDR5 with error correction for the kit to function.

Questions about this item

What throughput limit does the DDR5 4800 interface impose on these modules?

The DDR5 4800 rating means the modules operate at 4800 MT/s, so the peak data rate is capped at that speed.

What physical slot and pin count do the 64 GB RDIMMs require?

Each module is a 288-pin RDIMM that fits a standard DDR5 server DIMM slot with the registered notch position.

What is the correct installation sequence for a dual-channel kit like this 2×64 GB set?

Install one module per channel following the motherboard's population guide; the common mistake is placing both sticks in the same channel.
