Different-sized RAM sticks

[IAmAndre]

Hi,

 

I'm buying this black Friday a laptop that comes with 8GB of RAM, which I want to upgrade. Would buying a 16GB stick running at the same frequency impact the performance negatively vs an 8GB one?

 

Thanks

probably not, just be sure it's compatible

Most likely not, do pay attention to the CAS Latency as well not just frequency to make sure every thing is right... only catch is that you will only have Dual Channel enabled up to 16gb (8x2) if you happen to fill above this it'll run on single channel.

 

Do you really need 24gb of ram on a laptop?

You mean putting a 16GB stick and a 8GB at once, it won't have performance issues 99% of the times, but the 16GB stick only 8GB of it will be in dual-channel mode, while the rest will be in single channel mode.

Actually I'll be doing some After Effects,

which can be RAM-hungry.

Interesting, I didn't that was possible. I guess no performance loss in this case

Yeah, it will just operate at the slower RAM state
