Capacity 64GB (2 x 32GB)

  • 64 GB kit adds 2 × 32 GB modules for multitasking headroom
  • DDR4 2666 (PC4-21300) CL19 runs at 1.2 V for efficient speed
  • ECC unbuffered design protects data integrity in NAS workloads
  • 260-pin SODIMM fits ASUSTOR AS7110T Lockerstor 10 Pro bays
  • Backward compatible with 2400 MHz and 2133 MHz systems

Capacity and audience

This kit supplies 64GB of DDR4 ECC SODIMM memory as two 32GB modules for the ASUSTOR AS7110T NAS. It targets administrators who need error-correcting capacity for ZFS pools, virtual machines or database workloads on that specific platform.

Speed ceiling and fallback

The modules run at 2666 MT/s with CL19 latency and 1.2V operation, matching the PC4-21300 JEDEC standard. They will also operate at 2400 MT/s or 2133 MT/s if the system firmware negotiates a lower data rate.

Physical layout and daily handling

Each stick uses a 260-pin SO-DIMM edge connector without a heat spreader, keeping the profile low for dense NAS chassis. The unbuffered 2Rx8 organisation plugs directly into the AS7110T slots, allowing a straightforward upgrade without tools or cable routing.

Questions about this item

Should I buy this 64 GB kit or a single 32 GB module?

The kit contains two matched 32 GB modules giving 64 GB total; using both enables dual-channel bandwidth on the ASUSTOR AS7110T, while a single module would run in single-channel mode and leave the second slot empty.

What does the 2666 MT/s rating deliver in the AS7110T?

The modules run at 2666 MT/s (PC4-21300) with CL19 latency at 1.2 V, providing the maximum JEDEC-standard throughput the NAS memory controller supports for ECC SODIMMs.

Is the 260-pin DDR4 ECC SODIMM interface compatible with my AS7110T?

Yes — the 260-pin DDR4 ECC unbuffered SODIMM form factor matches the AS7110T slots exactly, and the kit is validated for that model; it will also down-clock to 2400 or 2133 MT/s if the system requires it.
