I'm wondering if I can add a 16GB DDR4 2666MHz RAM module to my laptop that already has a 16GB DDR4 3200MHz RAM module, especially since my laptop's motherboard is limited to 2400MHz. Will this setup work safely without causing issues?

Mixing RAM modules is generally a risky move and can lead to system issues, especially because you're blending different speeds and potentially different timings. I'd advise against it if you want to keep things stable.
You can give it a shot, but mixing RAM modules isn't always a sure thing. Sometimes it works fine, and other times you might run into problems. Just keep your fingers crossed!
I've seen laptops that have warnings about using memory that exceeds their specs. Even if it says it supports 5600MHz, pushing higher speeds can lead to issues. But since your laptop is limited to 2400MHz, it might still work all at that speed.
In the best-case scenario, they might all run at 2400MHz together. However, it's possible they could drop down to 2133MHz, or there's even a chance they won't work together at all. Just be prepared for any scenario!
It's probably okay to try, but checking with your laptop's manufacturer would be smart since they know the hardware best. Also, remember that laptops use different RAM sizes than desktops, specifically SODIMM.
Thanks for the heads up! I looked it up and I see I need SODIMM for my laptop.
If both RAM sticks are JEDEC compliant, like having CL19 for 2666 and CL22 for 3200, they should default to the lowest speed, which in your case is 2400MHz without any problems.
Sounds like it's safer to avoid the mix. Thanks for the advice!
