16GB DDR4 2666 ECC UDIMM for ASUS LOCKERSTOR NAS

This NEMIX RAM module provides 16GB of DDR4 2666 memory in a single 288-pin UDIMM. It operates at CL19 latency with a 1.20V voltage. The unbuffered ECC design uses a 1Rx8 configuration built with major OEM chips.

Suits ASUS LOCKERSTOR NAS owners adding ECC capacity

Buyers who need registered DIMMs or a heat spreader should look elsewhere. Systems requiring speeds above 2666MT/s or lower CAS latency than CL19 are not supported by this module. Non-ECC platforms cannot use the error-correction feature.

ECC unbuffered UDIMM decides compatibility

The module is an unbuffered ECC UDIMM, so it only works in platforms that accept that exact memory type. Buffered or registered memory slots will not accept it. Verify your NAS or motherboard specifies unbuffered ECC UDIMM support before purchase.

商品問答

How do I install this 288-pin DDR4 ECC UDIMM in my ASUS LOCKERSTOR NAS and what step is often missed?

Power off the NAS, open the chassis, align the notch on the 288-pin module with the slot key, press firmly until the retention clips click, then power on and verify the 16GB capacity in the system BIOS or DSM info page — the step often missed is confirming the module shows at the rated 2666 speed.

What maintenance or replacement will this 1Rx8 ECC UDIMM need over time?

No routine maintenance is required; ECC corrects single-bit errors automatically, but if the NAS logs uncorrectable memory errors or fails to boot, the 16GB stick should be replaced.

What limit appears first when this CL19 1.2V module runs sustained workloads?

The CAS latency of CL19 at 2666 MT/s sets the access timing ceiling, and the fixed 1.20V operating voltage limits headroom for extended heavy use.
