Best RAM for ASUSTOR Lockerstor 4 Gen2 AS6704T

How to upgrade your AS6704T RAM.

ASUSTOR Lockerstor 4 Gen2 AS6704T is one of the latest Intel-powered NAS enclosures from the company. We’re looking at a speedier Celeron processor, M.2 slots for caching or storage, and 4GB of DDR4-2666 RAM. Thanks to this newer CPU, it’s possible to push this NAS up to 16GB of RAM. This guide will show you how.

What RAM is supported by ASUSTOR AS6704T?

Because the ASUSTOR AS6704T uses the Intel Celeron N5105 processor, it supports up to 16GB of DDR4-2933 RAM, at least according to Intel’s own documentation on the SoC. For this NAS, ASUSTOR preinstalls 4GB of RAM, but this can be switched out for two 8GB modules for the full 16GB.

While it should be possible to use any compatible 8GB module with the ASUSTOR AS6704T, extra care should be taken to select a SODIMM module with as close a match to the DDR4-2933 speed. The kits and modules I recommend here are DDR4-3200, which will underclock slightly to match what’s supported by the processor.

Having 16GB of DDR4 RAM inside the best NAS is one way to create quite a powerful home server for various tasks.

If you want to go the officially supported route, ASUSTOR’s own RAM modules are the way to go for the AS6704T. They’re way more expensive than third-party modules, but you’ll be guaranteed support.

Lexar’s 8GB is a little more affordable than the official ASUSTOR memory and will work well with the Intel Celeron N5105 processor. The 3200MT/s speed would be lowered to match what the CPU supports, however.

We’re now moving into the much more reasonably priced RAM range with the G.SKILL RipJaws. This 16GB kit (consisting of two 8Gb modules) is fast and will run well on a NAS.

Lastly, we’ve got Crucial, which produces SODIMMs for pretty much everything, including NAS enclosures. This 16GB kit is amazing for giving your NAS a boost.

How to upgrade the RAM in ASUSTOR AS6704T

Installing (and removing) RAM inside the ASUSTOR AS6704T is a straightforward process, especially compared to other NAS enclosures. All that’s required is the removal of the outer chassis cover and the two memory slots are easily accessed without any tools.

I’d recommend running a memory test on the purchased RAM using an available PC, if possible, before installing them inside the NAS.

  1. Unscrew the outer case panel on the rear.
  2. Pull the case panel towards the rear of the NAS to remove it.
  3. Remove the preinstalled 4GB RAM module.
  4. Install the newly purchased RAM module into that same slot (or both slots if using two 8GB modules).
  5. Reinstall the case panel by reversing steps 1-2.

That’s all there is to it! Simply power up the NAS and double-check ADM is seeing the full capacity installed.
