The article basically fits into the Aspire C22-820 All-in-One PC, as this supports DDR4-SODIMM RAM with 2400 MHz and only has one memory slot. The RAM must be used as a single module, which is the case with this 1 x 8GB DDR4-2400 SO-DIMM RAM.
It is important that the PC only has one slot and that the new RAM replaces the existing one. The voltage of 1.20 V and the clock frequency of 2400 MHz are compatible with the Aspire C22-820, which uses DDR4-2400 RAM.
Note that there are reports that some 8GB modules do not always boot smoothly, a BIOS update may be necessary if problems occur. Overall, the RAM type and speed is suitable for the PC.
We cannot warranty a full compatibility with the NAS. The product made for it is this article :
N°11908371
You can upgrade until maximum 8 GB (4 GB + 4 GB)

Unfortunately I can't confirm that. I have installed it in my Lenovo ideapad 330. It works perfectly. I simply checked first to see if pin 260 would fit. The product itself is tip top.
Kind regards

I briefly consulted the manufacturer on this, and they recommend only using the QNAP RAM, otherwise the warranty will expire. And with the RAM that is installed, the same performance should also be used, as otherwise the performance can drop.
At Crucial there are 3 different RAMs that meet Apple's conditions:
"Use SO-DIMMs (Small Outline Dual Inline Memory Modules) that meet the following specifications: PC4-2400, Unbuffered and without parity, 260-pin DDR4 SDRAM running at 2400 MHz."

Differences exist between dual ranked and single ranked, among others

Which processor is installed in the device?
Which RAM bar is already present? If possible, use a second RAM with the same characteristics and from the same manufacturer.
yes, you can. but you will have to install 2 (the imac has 4 slots that are divided into 2 banks. you always have to fully populate a bank, so you need 2 or 4 modules. 2 are already in).
Technically yes, but if you want an officially supported module by a memory vendor, then the following module should be considered instead:
Kingston KCP424SS8/8 (1x, 8GB, DDR4-RAM, unbuffered)
It's a bit more expensive though.
