System-specific 64GB DDR4 kit

This 64GB kit contains four 16GB DDR4 SODIMM modules built for QNAP TVS-873/e series NAS units. Each stick is a 260-pin unbuffered non-ECC module rated at 2400MHz with CL17 timings. The kit targets administrators who need the maximum 64GB capacity across all four memory slots in these appliances.

DDR4 2400 SODIMM limits

The DDR4 2400 interface caps transfer rates at PC4-19200 and the SODIMM form factor fits only 260-pin laptop-style slots. CL17 latency and 1.2V operation are fixed by the JEDEC standard for this speed grade. All four modules will run at the slowest installed module's speed, so mixing with slower sticks reduces overall throughput.

Pre-install checks

Verify the NAS model is one of the listed TVS-873/e variants and that all four slots are free for a matched set. Confirm the system runs a 64-bit operating system to address the full 64GB capacity. Ensure no ECC or registered modules are already installed, as this kit is non-ECC unbuffered only.

Questions about this item

How do I choose between the 16GB modules and the full 64GB kit?

The kit contains four 16GB modules for a total of 64GB, matching the four SODIMM slots in the TVS-873/e series.

What does the 2400MHz speed mean once the memory is installed?

The system will run the memory at up to 2400MHz; if any installed module is slower, all modules drop to that lower speed.

Does the 260-pin DDR4 SO-DIMM interface limit capacity or voltage?

The 260-pin DDR4 SO-DIMM form factor operates at 1.2V and supports the 16GB per module density used in this kit.
