16GB DDR4 ECC UDIMM for servers

This 16GB DDR4 2400 ECC UDIMM module is built for server and workstation systems that require error-correcting memory. It operates at 1.20V with CL17 latency and uses a 2Rx8 unbuffered design.

Suited for Synology D4EC-2400-16G replacement

This module matches the Synology D4EC-2400-16G specification for compatible upgrades. It is not for systems that need registered or load-reduced DIMMs, nor for platforms that only accept non-ECC consumer memory.

Verify DDR4 ECC UDIMM support first

Check that your motherboard or server accepts DDR4 ECC unbuffered DIMMs at 2400MHz before ordering. Confirm the maximum capacity per slot and total system limit in your hardware documentation.

商品問答

Does this 288-pin DDR4 UDIMM need a server motherboard that supports ECC and unbuffered memory?

Yes, the module is an ECC unbuffered DIMM, so the motherboard must accept ECC UDIMMs and provide a DDR4 288-pin slot.

Will this 2Rx8 1.20V module run stably with my existing 1Rx8 DDR4 ECC UDIMMs?

Mixing ranks is usually possible, but the system will operate at the slowest common speed and timing; check the motherboard manual for supported rank configurations.

How can I confirm the stick is running at 2400MHz CL17 with ECC active after installation?

Enter the BIOS or use a tool like CPU-Z to verify the reported speed of 2400MHz, CAS latency of 17, and that ECC status shows enabled.
