Hi there! You're taking the right first steps in PC building. The short answer is yes, you can run dual-channel with the new stick if it matches your system's requirements. Just make sure both sticks have the same speed and are compatible with your motherboard. It's also a good idea to double-check the specifications beforehand. Let me know if you need more details!
I think the problems from combining very different RAM sizes, rates, and brands are more than compensated by the speed of single-channel memory. I’d suggest either go back and buy two 8GB units, or keep the 16GB model and upgrade later.
In dual channel mode the system becomes unstable, performing writes and reads from both sticks simultaneously. It resembles raid0 for memory, but with varying stick sizes; crashes occur when writing beyond 4GB on each stick. Single channel mixed sizes work fine without problems.
Thanks for the update. I also think it's too uncertain to proceed. Sadly, giving it back isn't an alternative now. I might have to try selling it to someone else at a slight loss.
It depends on the motherboard and BIOS you have. Certain models support it while others don't. It's not ideal, but if that's the only option, it might work at least.
