I've installed 8GB of RAM (two 4GB sticks), but the system is only showing 4GB as available physical memory. I'm using a 64-bit operating system, and I've checked with CPU-Z, which indicates both sticks are recognized, so it seems like a hardware issue isn't the problem. What could be causing this, and how might I fix it?

What motherboard are you using? It could be limited on the maximum RAM it can handle. Just double-check both sticks are the right type for your motherboard (like DDR4). If everything checks out, maybe one of the sticks is faulty.
Just a quick check—in your system settings, is the operating system confirmed to be 64-bit? That would explain why it recognizes only 4GB. But if it's showing 8GB now, it seems like a temporary glitch.
Are you running a 32-bit or 64-bit version of Windows? If it's 32-bit, then it can't address more than 4GB of RAM. But you mentioned you're on 64-bit, so that shouldn't be an issue.
