16GB DDR4 ECC UDIMM kit

This A-Tech kit provides 16GB of DDR4 ECC unbuffered memory across four 4GB modules. It is built for servers and workstations that require error-correcting code support and 288-pin DIMM slots. The modules run at 2133 MHz with a CAS latency of 15 and operate at the standard 1.2V voltage. Each module uses a single-rank 1Rx8 organisation.

Suited for ECC-capable servers and workstations only

The kit suits administrators upgrading compatible DDR4 servers or workstations that accept unbuffered ECC UDIMMs. It is not suitable for desktop or laptop computers, which cannot use ECC unbuffered memory. Buyers who need non-ECC memory or higher-capacity modules should look elsewhere.

Straightforward DIMM installation with channel rules

Installation follows standard 288-pin DIMM seating in the correct memory channels as specified by the system manual. The most common issue is installing these modules in a desktop or laptop, which will not recognise the ECC unbuffered format. Verifying the platform's qualified vendor list before purchase prevents compatibility problems.

Perguntas sobre este artigo

Does my motherboard need 288-pin DDR4 slots that support ECC unbuffered UDIMM modules?

Yes, this kit requires a server or workstation motherboard with 288-pin DDR4 slots that accept ECC unbuffered UDIMM modules; it will not work in standard desktop or laptop boards.

Can I mix these 2133 MHz CL15 1Rx8 modules with existing slower or higher-latency ECC UDIMM sticks?

The system will run all modules at the speed and timings of the slowest installed kit, so mixing is possible but overall memory performance will drop to the lowest common denominator.

How can I confirm the kit is running at 2133 MHz with CL15 timings and ECC active after installation?

Check the BIOS memory information screen or use a tool such as CPU-Z to verify the reported speed of 2133 MHz, CAS latency of 15, and that ECC status shows enabled.
