QNAP TVS-h874T memory upgrade

This 64 GB kit contains two 32 GB DDR4 3200 SODIMM modules built for the QNAP TVS-h874T NAS. It targets administrators who need more capacity for virtual machines, containers or large file caches in that specific platform.

Low-voltage unbuffered operation

Each module runs at 1.2 V with CL22 latency and no heat spreader, keeping power draw modest and acoustics unchanged in the NAS chassis. The 2Rx8 organisation is handled by major OEM DRAM from Samsung, Micron or Hynix.

Two-slot kit for matched capacity

The pair fills both SODIMM slots on the TVS-h874T, delivering 64 GB in a matched configuration without mixing ranks. Builders who need ECC, registered DIMMs or a different form factor cannot use this kit.

Questions about this item

How do I install the 260-pin SODIMM modules in the QNAP TVS-h874T and what step do people miss?

Power down the NAS, remove the chassis cover, insert each 32 GB module at an angle until the gold contacts disappear, then press firmly until the side clips snap shut; the step often missed is verifying both clips lock automatically.

What maintenance or replacement will this 64 GB DDR4 kit need later?

No scheduled maintenance is required; the modules have no heat spreader and run at 1.20 V, so only a future capacity upgrade would prompt replacement.

What limit appears first under sustained load with these CL22 3200 MT/s modules?

The CAS latency of 22 cycles at 3200 MT/s sets the timing ceiling, so latency-sensitive workloads hit that boundary before throughput saturates.
