Can I add a a 1x8gb stick of ram to 2x4gb of ram?

[Crumbal]

I have 8gb of ram and I want to upgrade to 16gb and a 1x8 stick of ram appears to be cheaper than 2x4 sticks of ram on Amazon but im not sure if it will cause problems if I add a 1x8 stick of ram to 2x4 sticks of ram or not. Any answers will be appreciated.

You will lose the Dual Channel.
On AMD Ryzen this will mean you lose a good chunk of cpu performance.

It doesn't affect Intel as much but does affect nonetheless.

Incorrect. Both AMD and Intel have a flex mode, in which the 2x4GB will keep running in dual channel, and the 8GB will be running in single channel.

That would be correct. If you have anything not Ryzen, feel free to buy the 1x8GB. You'll only notice a difference in memory specific benchmarks. It's inconsequential for real world home applications, because there's a ton of slower stuff dragging you down anyway.

yes but obviosly you dont have to take flex mode youc an use dual channel by simply but the 1x8GB in one channel and the 2x4GB in the other channel. Then both channels have the same ammount and you run in dual channel just fine.
