16GB DDR3 ECC Kit

This kit supplies 16GB of DDR3 1066 memory in four 4GB unbuffered ECC UDIMM modules. It targets desktop workstations, servers and NAS systems that require error-correcting memory for data integrity. The modules run at 1.5V with a CAS latency of CL7 and use the standard 240-pin form factor.

Replaces Non-ECC or Smaller Kits

The upgrade is worth it when your current system uses non-ECC memory and you need hardware-level error correction for critical workloads. It also makes sense when the board has four slots and you want to populate them with a matched dual-channel kit rather than mixing modules of different speeds or capacities.

Check Board Compatibility First

Verify that your motherboard or server platform supports DDR3 1066 ECC unbuffered UDIMMs and can address the full 16GB across four slots. Confirm the memory controller accepts 2Rx8 organisation and 1.5V operation. Ensure the BIOS is current enough to initialise all four modules at the rated speed.

Perguntas sobre este artigo

Will the 240-pin DDR3 UDIMMs fit my desktop motherboard slots?

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

What is the correct way to seat the four modules for dual-channel operation?

Insert each stick firmly until the retention clips click; the common mistake is stopping when the gold contacts first touch the socket instead of pressing until both clips lock.

Do these ECC modules need any firmware updates or periodic replacement?

No firmware is involved and the JEDEC-compliant DDR3 chips have no scheduled replacement interval; they run at 1.5 V for the life of the system.
