RAM Upgrade

I was wondering if anyone could lend me a hand here.
I recently went ahead and upgraded my RAM to 32GB on my Dell XPS.
Now, I’m just a bit concerned—how exactly am I supposed to verify that the entire capacity is actually functioning correctly and that everything is running smoothly?
Thanks in advance for the help!

Open up CPU-Z. It’ll show you the frequency, capacity, and whether you're actually running in dual channel mode.

If you're paranoid about whether your RAM is actually stable or just throwing silent errors, run a stress test—something like Memtest86.
