16GB DDR5 4800 ECC UDIMM Server RAM

This 16GB DDR5 module runs at 4800MHz with CAS latency 40 and 1.10V operation. It uses a 288-pin unbuffered DIMM layout with 1Rx8 organisation and on-die ECC for data integrity in server workloads.

Suits servers needing single-rank ECC UDIMM upgrades

Not suited for platforms that require registered or load-reduced DIMMs, nor for consumer boards lacking DDR5 ECC UDIMM support. Buyers needing higher density per slot or registered signalling should look elsewhere.

Installs like any standard 288-pin DDR5 UDIMM

Align the notch, press firmly until the retention clips click, and follow the system manual for channel population rules. Common issues arise when mixing ranks or using non-ECC slots that disable error correction.

Questions about this item

Will this 288-pin DDR5 4800 module work in my current motherboard?

This module requires a motherboard with a 288-pin DDR5 DIMM slot that supports DDR5 4800 speed, ECC UDIMM, and 1.10 V operation.

Can I add this 1Rx8 ECC stick alongside my existing DDR5 non-ECC memory?

Mixing ECC and non-ECC modules is not supported; the system will either disable ECC or fail to boot, so all slots should use ECC UDIMMs.

How do I verify the CAS latency 40 and 4800 MT/s are active after installation?

Enter the BIOS or use a tool such as CPU-Z to confirm the memory runs at DDR5 4800 with CL40 timings and shows ECC enabled.
