Hi, I currently have a Corsair 8GB 2400 MHz system with clock speeds of 14-16-16-31 and a voltage of 1.2V. When idle, about 3.5 GBs of RAM is being used. I’m thinking about upgrading by adding another 8GB or 16GB. Questions: 1) Should I install 16GB 2400 MHz RAM with different clock speeds and 1.35V? Or 2) Should I add 8GB 2400 MHz RAM with different clock speeds and 1.35V? Or 3) Would it work if I upgrade to a 3000 MHz version, like 8GB or 16GB, downclocking to 2400? My main concern is that my RAM is three years old—its clock speeds and voltage aren’t specified. What’s the best approach for upgrading?

Yes, it's technically possible. However, this setup would cause the 8 gigabit to run in single-channel mode and the 16 gigabit in dual-channel, which means you'd experience reduced performance compared to using dual-channel exclusively.

You can mix different speeds of RAM fine but not different voltages. You sure its a 1.2v kit? The VAST MAJORITY of DDR4 is 1.2v at JEDEC spec and 1.35v at XMP spec so do you have XMP enabled in BIOS? If it really is a 1.2v DDR4 Kit (and they do exist) then you're honestly best replacing it all for a matching pair 16GB Kit so you 100% know they'll work together. Edit - Forgot to say that high idle RAM usage isn't necessarily a sign you're running low. Windows uses it to do background stuff while the system is idle and will free it all up again once you start actually doing stuff.

I captured a photo of the RAM module. I believe it's 1.2V. I'm not sure if XMP is activated in BIOS. I was also considering purchasing another RAM package. Typically, when I launch games on Steam, RAM usage reaches up to 6GB. Additionally, I intend to stream, which means I'll need more background applications running.

Would this setup function properly? I don’t mind the performance because there will be ample RAM. The configuration looks solid with the slots arranged correctly.

you'll be running in single channel and all will be clocked at 2400, you can get rid of the original stick and just buy a new kit, as for voltage, i didn't find anything that says it wont work, but im still not sure about it, some people say that it's not ideal but should technically work.
