16GB DDR4 ECC Kit for Workstations

This dual-channel kit provides 16GB of DDR4 3200MHz memory with CL22 latency and ECC error correction. It is built for desktop PCs, workstations, servers and NAS systems that require data integrity. The modules run at a standard 1.2V JEDEC voltage.

Capacity and Speed Headroom

The 2x8GB configuration delivers 16GB total capacity for multitasking and larger datasets. Rated at 3200MHz PC4-25600, the modules also run at 2933MHz, 2666MHz, 2400MHz and 2133MHz speeds automatically. ECC function adds overhead but protects against single-bit errors in critical workloads.

Unbuffered 288-Pin Design

These unbuffered UDIMMs fit standard 288-pin desktop DIMM slots without registration buffers. The black PCB has no heat spreader, keeping the profile low for tight CPU cooler clearance. Installation is a straightforward DIY upgrade on compatible motherboards supporting ECC unbuffered memory.

Questions about this item

Will the 3200MHz CL22 ECC UDIMM run with my existing 2666MHz DDR4 sticks?

The modules are backward compatible with 2133MHz, 2400MHz, 2666MHz and 2933MHz DDR4, so they will operate at the speed of the slowest installed memory.

How can I verify the ECC function is active after installing the 288-pin kit?

Enter the system BIOS or UEFI and confirm that ECC support is enabled; the firmware will typically display the ECC status on the memory information screen.

What comes in the 16GB dual-channel package and do I need a heat spreader?

The box contains two black 8GB 1RX8 DDR4 3200MHz CL22 ECC unbuffered UDIMMs; no heat spreader is included or required for these 1.2V modules.
