Adding RAM - TS-451D2

[andrew.0101]

I have a TS-451D2. The RAM specs indicate DDR4 - "4 GB SO-DIMM DDR4"
https://www.qnap.com/en/product/ts-451d2/specs/hardware

Hardware Info from the actual device suggest there's an A-DATA module installed.

Adding another 4GB, can I assume the following would be a safe bet?

ADATA 4GB DDR4 2666MHz SODIMM Memory Module
• Memory: 4GB
• Module Type: SO-DIMM
• Memory Type: DDR4
• Speed: 2666MHz
• Interface: 260-pin
• IC Configuration: 512MX16

SSH queried the NAS for ram the specs.

The only difference I can see with the RAM I found online and what's reported by the device is the speed:
from webshop: 2666MHz
on device: 2400 MT/s

Could that be an issue?

Yes, I think that module will be OK.

The specs match those indicated by the accessories store for that model NAS: https://shop.qnap.com/index.php?route=p ... ory_id=587

Cheers, I've been searching all morning for that website.
I came across it before I bought the NAS, and couldn't find it again.
In fact, it was my recollection of the $120USD 4GB price! that made me suspicious of the $30USD A-DATA match I've managed to find.

I wouldn't think twice about mixing this in a PC, understanding that the 2666 RAM would just run at 2400.
But I wanted to make sure the same applied with the QNAP nas.

Any idea why it's sooo expensive on shop.qnap?

I can only speculate, so I won't.

Fair enough, thanks for your help.
I just ordered the 4GB ram

[andrew.0101]

For the record the $30USD ram I purchased looks to be identical to the factory installed module.
8GB now and working perfectly.

Nice work.
