ECC Unbuffered DIMM for Workstations

This 16GB DDR4 module runs at 2666 MT/s with CL19 latency and 1.2V operation. It targets workstations, servers and NAS systems that require error-correcting code memory. The unbuffered 2Rx8 design fits standard 288-pin desktop slots without registration overhead. JEDEC and ROHS compliance ensures a warranty-safe upgrade path.

Thermals and Power in Normal Use

Operating at the standard 1.2V keeps power draw low and heat output minimal during typical workloads. No heat spreader is fitted, so the VLP profile relies on case airflow for cooling. The low voltage and absence of LEDs contribute to quiet, efficient operation in densely populated DIMM banks.

What the Bundle Changes

The module ships as a single 16GB DIMM with no extra cables, brackets or software utilities. OWC validates every stick in-house to meet or exceed OEM specifications for the listed Hynix and Micron part numbers. A limited lifetime warranty and free technical support back the upgrade, but no installation media or monitoring tools are included.

Perguntas sobre este artigo

How do I install the 288-pin VLP DIMM and what step do people often miss?

Power off the system, open the case, align the notch on the 288-pin module with the slot key, press firmly until both retention clips click, then verify in BIOS that the module reports 16 GB at 2666 MT/s and ECC is enabled; the step most often missed is confirming ECC mode in firmware after the physical install.

What maintenance or replacement will the 16 GB ECC unbuffered module need later?

No scheduled maintenance is required; keep interior dust-free and ensure the 1.2 V supply remains stable. If a correctable error count rises or the system logs uncorrectable ECC events, replace the module — otherwise it runs for the system life.

What limit appears first when the 2Rx8 CL19 kit runs sustained workloads?

The JEDEC 1.2 V / CL19 timing ceiling is reached before thermal throttling; sustained write/read streams max out at the rated 2666 MT/s bandwidth, so throughput plateaus at the spec data rate rather than hitting a temperature wall.
