RAM upgrade quenstion for Acer Aspire 5 A515-51G

Hello,

I have an Acer Aspire A515-51G and I want some opinions before I upgrade my RAM.

Right now the laptop has 8GB (4GB soldered on motherboard and 4GB switchable). I'm thinking of removing the 4GB and placing a 16GB, in order to have 20GB (which is the maximum supported for this motherboard). Current RAM run at 2133Hz with CAS 15 and runs at Dual Channel. My two final options are Corsair and G.Skill

1) https://www.corsair.com/eu/en/Categories/Products/Memory/Mainstream-Memory/Corsair-Memory-16GB-(1x16GB)-DDR4-SODIMM-2133MHz-C15-Memory-Kit/p/CMSO16GX4M1A2133C15    [70€ where I live - ~79$]

2) https://www.gskill.com/specification/2/197/1537264131/F4-2133C15S-16GRS-Specification  [58‎€ where I live - ~65$]

My quenstion is do you think that I'll face any problems if I place a 16GB with the current 4GB soldered. Because they won't run at Dual Channel anymore (it's called flex-mode if I'm not mistaken). Will it be better to have 8GB Dual Channel or 20GB Flex-Mode( with thepossibility of problems occurring)? Lastly, do you suggest one of the two manufacturers, did anyone faced a similar problem?

Thanks in advance,

If you choose a 16gb ram model, I believe that there will be no problems, as long as it has the same characteristics as speed, cas latency. However, it will actually work in flex mode, as 8gb will work in dual channel and the remaining 12gb will work in single channel.

Thanks for your answer. You think I will spot the difference on heavy tasks and workload between (4+4) GB Dual Channel vs  (4+4) GB Dual Channel - 12GB Single Channel.

I would choose to buy a 16gb ram memory, even if it works in flex mode. That way, despite the dual channel not working completely, windows would have more free ram memory to perform other tasks.
