384GB DDR5-5600 ECC UDIMM Kit

This 384GB kit contains eight 48GB DDR5-5600 ECC unbuffered DIMMs built for servers and workstations that require error-correcting memory. Each module runs at PC5-44800 with a CAS latency of 40 and operates at the standard 1.10V. The dual-rank 2Rx8 organisation helps dense configurations reach high capacity per channel. It is not compatible with desktop or laptop platforms that lack DDR5 ECC UDIMM support.

Thermals and power draw

Modules operate at the JEDEC-standard 1.10V without a heat spreader, relying on chassis airflow for cooling. The low voltage keeps power draw modest for the total 384GB capacity, and the unbuffered design avoids the extra current of registered DIMMs. Acoustic impact is negligible because the kit adds no active cooling components.

What the bundle changes

The kit delivers eight matched 48GB modules in a single package, removing the need to source individual sticks and reducing the risk of mixing revision codes. Population of all eight slots enables maximum memory bandwidth on platforms with eight-channel controllers. Buyers who need fewer than eight modules or who require registered ECC DIMMs should select a different configuration.

Questions about this item

How do I install the 288-pin DDR5 ECC UDIMM modules and which step is often missed?

Power off the server, open the chassis, align each module's notch with the slot key, press firmly until both retention clips click, then verify in BIOS that all eight 48GB modules are detected at 5600 MT/s.

What maintenance or replacement will the 384GB DDR5-5600 kit need over its service life?

No scheduled maintenance is required; keep air paths clean so the unbuffered modules stay within thermal limits, and replace any module only if memory diagnostics report correctable or uncorrectable ECC errors.

What limit appears first when the eight dual-rank 48GB modules run sustained workloads at 1.1V?

The memory controller's maximum supported capacity or rank-per-channel limit is reached before voltage or thermal thresholds, so confirm the platform's 384GB/2Rx8 ceiling before deployment.
