Is it fine to use both RAM slots on my motherboard?

Yes, you can definitely use both slots! Just make sure to get RAM sticks that match each other for better performance, preferably from the same kit for stability.

You can use both slots, but keep in mind that the memory controller on your CPU might struggle with more than two sticks if you're pushing limits. Most motherboards are designed this way because most users don’t need more than two sticks.

Yes, as long as the RAM is compatible, you can fill both slots. Just ensure that they’re the same size and speed for optimal dual channel performance.
