System-specific SODIMM for QNAP NAS

This 32GB DDR4 2666 module is built for QNAP TVS-H674T and TVS-H874T systems. It uses a 260-pin SODIMM form factor with CL19 latency and 1.2V operation. The single stick adds capacity without occupying multiple slots.

Passive cooling and standard power draw

No heat spreader is fitted, so the module relies on chassis airflow for cooling. Unbuffered non-ECC DRAM at 1.20V keeps power consumption low during typical NAS workloads. Silent operation is assured with no moving parts.

2Rx8 organisation on a single 32GB stick

The dual-rank 2Rx8 layout delivers 32GB in one module using major OEM chips from Samsung, Micron or Hynix. Systems limited to one SODIMM slot can reach full capacity. Buyers needing ECC error correction or registered buffering must choose a different part.

Questions about this item

How do I install the 260-pin SODIMM in my QNAP TVS-H674T and what step is often missed?

Power off the NAS, remove the chassis cover, insert the module at an angle until the gold contacts are hidden, then press down until the side clips click — the step often missed is fully seating both clips so the 1.20 V module makes solid contact.

What maintenance or replacement will this 32 GB DDR4 2666 CL19 module need later?

No scheduled maintenance is required; the unbuffered non-ECC SODIMM has no heat spreader or moving parts, so only a future capacity upgrade or a confirmed memory fault would prompt replacement.

What limit appears first when the NAS runs sustained workloads with this CL19 2Rx8 kit?

The CAS latency of 19 cycles at 2666 MT/s sets the timing floor, so latency-sensitive tasks hit that timing ceiling before the 1.2 V power envelope or the 2Rx8 rank structure becomes a bottleneck.
