QNAP TVS-H674T & TVS-H874T memory kit

This NEMIX RAM kit supplies 32 GB of DDR4 3200 memory in two 16 GB SODIMM modules. It is built for QNAP TVS-H674T and TVS-H874T NAS units that accept 260-pin unbuffered non-ECC memory. The kit suits administrators who need to expand system memory for heavier workloads or virtualisation tasks.

DDR4 3200 SODIMM limits

The modules run at 3200 MT/s with CL22 latency at 1.20 V. The DDR4 SODIMM standard caps transfer rates at this speed and voltage, so the kit cannot exceed the platform's maximum supported frequency. Systems that require ECC or registered DIMMs will not accept these unbuffered non-ECC modules.

2Rx8 dual-rank configuration

Each 16 GB module uses a 2Rx8 organisation, which determines how the memory controller addresses the chips. This rank structure must match the NAS motherboard's supported population rules for the upgrade to function correctly.

Questions about this item

Should I choose the 32GB kit or buy two 16GB modules separately?

The kit already contains two matched 16GB modules tested together for the QNAP TVS-H674T and TVS-H874T, so a single purchase guarantees dual-channel operation.

What does the 3200MHz rating mean once the memory is installed in my NAS?

The modules run at DDR4 3200 (PC4-25600) with CL22 latency at 1.20V, delivering the rated bandwidth as long as the NAS firmware enables the XMP or JEDEC profile.

Does the 260-pin SODIMM interface limit the speed or capacity I can use?

The 260-pin DDR4 SODIMM form factor is the standard for these QNAP models; it supports the full 3200MHz speed and 32GB total capacity without any adapter or down-clocking.
