  • Runs cooler at standard 1.2V JEDEC voltage
  • Installs easily in 288-pin UDIMM slots without tools
  • Works in slower 2133 2400 2666 2933 MHz systems too

Single 32 GB DDR4 module for QNAP NAS

This OWC memory upgrade delivers 32 GB of DDR4 3200 speed in a single 288-pin UDIMM. It is built for the QNAP TS-h977XU-RP, TS-h1277XU-RP, TS-h1677XU-RP and TS-h2477XU-RP models and runs at 1.2 V with CL22 latency.

Verify slot count and maximum capacity first

Confirm your NAS has a free 288-pin DDR4 slot and that the system firmware supports a 32 GB non-ECC unbuffered module. The board must accept 2Rx8 organisation and operate at 3200 MT/s or fall back to 2133, 2400, 2666 or 2933 MT/s.

Green PCB with no heat spreader

The module uses a bare green circuit board, so it fits tight drive cages without extra height. Gold-edge contacts seat firmly in the vertical DIMM socket and the 1.2 V rating keeps power draw low during continuous NAS operation.

Questions about this item

Does the box contain only the 32 GB module or are extra parts included?

The box contains a single 32 GB DDR4 3200 CL22 2Rx8 288-pin 1.2 V Non-ECC UDIMM. No cables, screws or tools are supplied.

Which of the listed QNAP models does this 32 GB stick fit?

It is validated for TS-h977XU-RP, TS-h1277XU-RP, TS-h1677XU-RP and TS-h2477XU-RP and replaces QNAP part numbers RAM-32GDR4S0-UD-3200 and RAM-32GDR4T0-UD-3200.

What does the 3200 CL22 rating mean once the module is installed in a compatible NAS?

It will run at 3200 MT/s with 22-cycle CAS latency at 1.2 V, and will automatically down-clock to 2933, 2666, 2400 or 2133 MT/s if the system requires a lower speed.
