8GB DDR4 2133MHz ECC UDIMM for servers

This 8GB module is built for Supermicro platforms that require ECC unbuffered memory. It runs at DDR4 2133MHz with a CL15 latency and 1.20V operation. The dual-rank 2Rx8 organisation uses Samsung chips and fits standard 288-pin UDIMM slots. It suits administrators expanding capacity in compatible rack or tower servers.

Standard voltage and unbuffered design

Operating at the DDR4 standard 1.20V, the module draws typical power for its speed grade without elevated voltage. The unbuffered topology keeps the signal path direct, which helps maintain low latency in supported systems. No active cooling is present on the DIMM itself, so thermal performance depends on chassis airflow across the memory slots.

Replaces non-ECC or lower-capacity UDIMMs

This kit upgrades systems currently running non-ECC memory where data integrity is now required, or adds density beyond 4GB modules. The jump is worth it when the platform validates the MEM-DR480L-SL02-EU21 part number and the workload benefits from ECC protection. It does not serve boards limited to registered DIMMs or speeds above 2133MHz.

Perguntas sobre este artigo

How do I install this 288-pin DDR4 UDIMM and what step is often missed?

Align the notch with the slot key, press firmly until both retention clips click, then verify the system POSTs and reports the full 8 GB at 2133 MHz.

What maintenance or replacement will this Samsung M391A1G43EB1-CPB module need over time?

No routine maintenance is required; if errors appear, run a memory diagnostic and replace the stick if failures persist.

What limit appears first when this CL15 1.20 V ECC unbuffered DIMM runs sustained workloads?

The JEDEC 2133 MT/s data rate and CL15 latency set the throughput ceiling before voltage or thermal throttling becomes a factor.
