32GB DDR4 ECC UDIMM kit for ASUS LOCKERSTOR NAS

This 32GB kit contains four 8GB DDR4 2666 modules built to the PC4-21300 standard. Each stick is a 288-pin unbuffered UDIMM with ECC and a 1Rx8 organisation. The memory runs at 1.20V and carries a CL19 latency. It is intended for owners of compatible ASUS LOCKERSTOR NAS units who need to expand system memory for virtualisation, heavy file serving or database workloads.

Verify NAS model and slot count before ordering

Confirm that your LOCKERSTOR appliance accepts 288-pin DDR4 ECC UDIMM modules and has four free DIMM slots for the full kit. The motherboard must support unbuffered ECC at 2666 MT/s and 1.20V operation. Check the vendor documentation for maximum supported capacity per slot and any population rules that could limit usable memory.

Steady throughput under continuous NAS workloads

The CL19 timing and 1.20V voltage deliver stable bandwidth during long file transfers, backup jobs or container hosting. ECC corrects single-bit errors on the fly, preventing silent data corruption during sustained read and write cycles. Unbuffered design keeps latency low for random-access patterns typical of multi-user NAS environments.

Questions about this item

What does the 32 GB kit contain and is anything else required for installation?

The kit includes four 8 GB DDR4 ECC UDIMM modules totalling 32 GB; no extra parts are needed for a compatible ASUS LOCKERSTOR NAS slot.

Why choose the 4 × 8 GB version instead of a different capacity kit?

This 32 GB kit uses four single-rank 1Rx8 modules at 2666 MT/s CL19, matching the ASUS LOCKERSTOR AS-8GECD4-U validated configuration.

What does the 2666 MT/s rating mean once the modules are installed in the NAS?

The memory runs at DDR4 2666 (PC4-21300) with CL19 latency at 1.20 V, delivering the rated throughput the NAS firmware expects.
