Server DDR5 ECC kit

This 128 GB kit contains eight 16 GB DDR5 RDIMM modules built for servers and workstations that require registered ECC memory. It is not compatible with desktop or laptop platforms.

Registered 288-pin design

Each module uses a 288-pin DIMM form factor with single-rank x8 organisation and operates at the standard DDR5 voltage of 1.1 V. The registered buffer reduces electrical load on the memory controller for stable operation in multi-module configurations.

Upgrade from slower DDR5

The kit replaces lower-speed DDR5 RDIMM sets when the platform supports 4800 MT/s operation and CL40 latency. The jump is worth it when workloads demand maximum registered ECC capacity at the baseline DDR5 data rate.

Questions about this item

What data rate does DDR5 4800 PC5-38400 actually deliver?

The modules run at 4800 MT/s, giving a peak bandwidth of PC5-38400 for registered ECC server workloads

What physical slot and module dimensions are required?

Each 16 GB stick is a 288-pin DDR5 RDIMM; the kit provides eight single-rank x8 modules that only fit DDR5 RDIMM server or workstation slots

Which installation step is most often missed with registered ECC DIMMs?

Populate the correct memory channels in the order specified by the system manual so the registered buffer and ECC initialise properly
