384GB DDR5 ECC RDIMM Kit

This 384GB kit contains eight 48GB DDR5 5600MHz registered DIMMs with ECC. It is built for servers that require registered memory and cannot be used in standard desktop PCs. The modules operate at 1.1V with a CAS latency of 46.

Thermals Noise Power

Registered DDR5 modules run at 1.1V, helping to limit power draw in densely populated server slots. The 2Rx8 organisation spreads load across ranks, supporting stable thermals under sustained workloads. No active cooling is included, so airflow must come from the chassis.

Build Fit Requirements

The 288-pin RDIMM form factor fits server boards wired for DDR5 5600 registered memory. Eight modules fill eight slots, leaving no free DIMM positions on typical dual-socket boards. Buyers needing non-ECC or unbuffered memory should look elsewhere.

Questions about this item

How do I install these 288-pin DDR5 RDIMMs and which step is most often missed?

Align the off-centre key notch on each 288-pin module with the slot, press straight down until both retention clips click, then verify in BIOS that all eight 48 GB sticks are detected at 5600 MHz.

What maintenance or replacement will this 384 GB kit need over time?

The modules have no moving parts and run at 1.1 V, so no scheduled maintenance is required; a stick is only replaced if memory diagnostics report uncorrectable ECC errors.

What limit appears first when this registered ECC memory runs sustained workloads?

The CAS latency of 46 cycles at 5600 MHz sets the timing floor, so latency-sensitive throughput plateaus before thermal or voltage headroom is reached.
