Server-grade ECC UDIMM

This RIMLANCE module is a 16GB DDR4 2666 ECC UDIMM built for server and workstation systems. It operates at 1.2V with a CL19 latency and a 1Rx8 organisation. The 288-pin DIMM provides error-correcting code protection for data integrity in critical applications.

Standard thermal and power profile

Running at the standard DDR4 voltage of 1.2V keeps power draw low during typical server workloads. The unbuffered design adds no extra register components that would increase heat output. Normal operation stays within conventional DDR4 thermal limits without active cooling on the module itself.

Sustained load behaviour

Error-correcting code function operates continuously during extended compute tasks such as database serving or virtualisation. The single-rank 1Rx8 layout maintains consistent signalling at 2666MHz PC4-21300 speeds. Reliability is preserved over long periods because ECC corrects single-bit errors as they occur.

Questions about this item

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

Align the notch on the module with the slot key, press straight down until both side clips click shut, then verify in BIOS that the 2666 MHz speed and ECC function are active.

What maintenance or replacement will the 1Rx8 ECC module need over time?

No routine maintenance is required; if a future memory test reports uncorrectable errors, replace the module with another 16 GB DDR4 2666 ECC UDIMM.

What limit appears first when the 1.2 V module runs sustained workloads?

The JEDEC-rated 1.2 V operating voltage and CL19 latency set the thermal and timing envelope; sustained loads will hit the 2666 MT/s data-rate ceiling before voltage or timing margins are exceeded.
