QNAP TS-351 compatible RAM

QNAP TS-351 compatible RAM

I ordered the QNAP TS-351 and wanted to do a RAM upgrade. I bought a 4GB Corsair ValueSelect DDR3L-1600 SO-DIMM CL11 module (1.35 V). While it fits the recommended QNAP specs, my NAS won’t boot (not the QNAP ADATA RAM product). Since you mentioned a RAM upgrade for this NAS, I am curoius which RAM you used.

I always recommend using Crucial memory. This seem to work all the time while other brands do not.

Just make sure you have same frequency RAM.  DDR3 SODIMM 204PIN  1600MHZ memory.

2 thoughts on “QNAP TS-351 compatible RAM

  1. Hello, by chance have you tried out any 8gb modules in the nas? If yes and supposedly it had been working , which one? 🙂

  2. Hello, I wonder if you have tested the unit with any other bigger memory 8Gb or any.
    If yes, what was working in that ts-351?

    Do I understand it correctly, even if I find samsung memory unit or kingstone or crucial, they will not work in ts-351 only these referenced memory units?
