Single-module 16 GB DDR4 upgrade

This 16 GB DDR4 2666 UDIMM adds capacity to compatible desktop systems. It runs at 1.20 V with CL19 latency and uses 288-pin unbuffered non-ECC chips. The module is built with major OEM DRAM and carries a lifetime replacement warranty from the manufacturer.

Best for standard desktop boards lacking ECC support

The stick suits mainstream desktop motherboards that accept non-ECC unbuffered DDR4 memory. It will not work in servers or workstations that require registered or ECC modules. Buyers needing error correction or registered signalling should choose a different part.

16 GB density in a single rank

The 16 GB capacity is provided on one module, leaving additional slots free for future expansion. This density fits boards limited to four slots while delivering a useful capacity increase. Verify the motherboard supports 16 GB per slot before purchase.

Questions about this item

Will this 288-pin DDR4 UDIMM fit my motherboard's standard desktop memory slots?

Yes, the module uses the standard 288-pin DDR4 UDIMM form factor and runs at 1.2V, matching typical desktop DIMM slots that support DDR4 memory.

What is the correct way to seat the module, and what step do people often miss?

Align the notch on the module's gold edge connector with the key in the slot, press down firmly until both side clips click locked; the step often missed is verifying both clips have fully engaged.

Does this non-ECC unbuffered module need any firmware updates or periodic maintenance?

No firmware updates are required for this non-ECC unbuffered DDR4 module; it operates without heat spreaders or LEDs, so no cleaning or component replacement is needed during its service life.
