Server ECC kit for multi-channel workloads

This 64GB kit contains eight 8GB DDR4 modules built for servers and workstations that require error-correcting unbuffered memory. Each module runs at 2133 MHz with CL15 latency and 1.20V operation. The dual-rank x8 organisation helps populate all channels on supported platforms.

Passive cooling and standard voltage

The modules have no heat spreader and operate at the DDR4 standard 1.20V, so thermal output stays low inside populated server chassis. Power draw scales with the number of populated slots rather than clock speed. Acoustic impact is negligible because no active cooling is required.

288-pin UDIMM layout and rank density

Each stick uses the 288-pin unbuffered DIMM form factor with a 2Rx8 configuration, which affects how many modules a memory controller can address per channel. Builders must verify that their system accepts ECC UDIMM modules and supports the total rank count across all populated slots. Desktop and laptop boards are not compatible.

Questions about this item

How do I install the 288-pin DDR4 UDIMM modules and which step is often missed?

Align each 288-pin module with the motherboard slot, press down until the retention clips click on both sides, and confirm the system detects all 64 GB in the BIOS — the step often missed is seating every module fully before locking the clips.

What maintenance or replacement will the 1.20 V ECC UDIMM kit need over time?

No scheduled maintenance is required; the modules have no heat spreader or moving parts, so only a failed stick would need replacement, which is covered by the lifetime warranty.

What limit appears first when the dual-rank 2133 MHz kit runs under sustained load?

The CL15 latency at 2133 MHz sets the throughput ceiling, so sustained workloads will hit the memory bandwidth limit before voltage or temperature becomes a factor.
