Capacity and role
This 4 GB DDR3 module delivers ECC unbuffered memory for desktops, workstations and NAS systems that require error correction without registered buffering. The single DIMM plugs into a standard 240-pin slot and runs at the JEDEC 1.5 V level.
Speed headroom
Rated at 1866 MT/s (PC3-14900) with CL13 latency, the module handles everyday multitasking and typical server workloads within its validated timing envelope. Performance scales with the platform memory controller, so maximum throughput depends on the host system capabilities.
Build fit
The stick uses a plain black PCB with no heat spreader, keeping the profile low for tight DIMM spacing. It requires a motherboard that supports DDR3 ECC unbuffered DIMMs; no extra power connectors, cooling or software configuration are needed beyond standard BIOS detection.

商品問答
Will this DDR3 1866 CL13 ECC UDIMM run alongside my existing DDR3 modules?
The module operates at DDR3 1866 with CL13 timing and 1.5V voltage. Mixing speeds or ECC with non-ECC memory is not recommended; the system will typically default to the slowest installed module and may disable ECC.
How can I confirm the 4GB DDR3 1866 module is running at PC3-14900 CL13 after installation?
Check the memory speed and timings in BIOS/UEFI or use a system information tool such as CPU-Z; it should report DDR3 1866 MHz, CL13 latency, and ECC support active.
Does the 240-pin UDIMM come with a heat spreader or any extra accessories in the box?
The module is supplied as a single black 240-pin UDIMM without a heat spreader; no cables, brackets or additional components are included.
