I recently upgraded my stationary computer with a bunch of new components, just harddisks remaining. Anyway, I bought 32GB RAM, might've been a bit overkill, but RAM is cheap these days. The motherboard support up to 64GB RAM and I'm running Windows 7 64bit. The RAM is 4*8GB, but in windows it only detects 8GB RAM. What can be the cause of this and how do I fix it?
