16GB DDR3 ECC Kit for Workstations

This kit provides 16GB of DDR3 1600 memory across four 4GB unbuffered UDIMM modules. It operates at CL11 latency with a standard 1.5V supply and includes ECC error correction. The 240-pin DIMMs are designed for desktop workstations, servers and NAS systems that require data integrity.

Upgrade from Non-ECC or Lower Capacity

Replacing standard non-ECC modules with this kit adds single-bit error correction and multi-bit detection for critical workloads. The jump is worth it when the platform supports ECC unbuffered memory and the application demands protection against silent data corruption. Four modules populate dual-channel boards fully for maximum bandwidth.

Steady Operation Under Continuous Load

JEDEC-standard timings and 1.5V operation keep power draw predictable during extended compute tasks. Without a heat spreader, airflow across the bare PCB manages thermals in typical server chassis. The modules maintain rated 1600 speed through sustained multi-threaded workloads such as virtualization hosting or file-system checksumming.

Questions about this item

Will the 240-pin DDR3 DIMMs fit my motherboard slots?

These modules use the standard 240-pin DDR3 UDIMM form factor, so they fit any desktop, workstation or server board that accepts DDR3 memory.

What is the correct way to seat the four 4 GB sticks, and what step do people often miss?

Open the retention clips, align the notch on each module with the slot key, press straight down until both clips snap shut, then verify the BIOS shows all 16 GB at 1600 MHz.

Do the ECC UDIMMs need any firmware updates or periodic replacement?

No firmware is required; the JEDEC-compliant DDR3 modules run at 1.5 V with CL11 timing and are rated for the life of the system under normal workloads.
