So I just put together a PC and when reading over the motherboard manual I happened to see something under the "memory" section regarding a 32-bit operating system limitation. Now, I've done some reading and it seems that this is just in regards to how much memory you can use (or something) when using a 32-bit operating system. I just want to confirm that I can indeed install my 64-bit windows 10 OS with 8 GB of RAM onto my "Gigabyte AM3+ AMD DDR3 1333 760G HDMI USB 3.0 Micro ATX Motherboard GA-78LMT-USB3" before I go opening my OS rendering it unreturnable.

Thanks for any help!

As RealBeast says, you can use a 64 bit version of Windows on your system with no problems, and, indeed you should.
The issue is the way the OS counts: A 32 bit OS can only count up to 4Gb then it runs out of fingers (so to speak), a 64 bit OS has more fingers so it can count higher.

I have been running a 64 Bit win home premium on a 64 bit processor for about 7 years now or so. As for the 'memory limitation' through various schemes a 32 bit system can address either 32 or 64 GB of ram. (I can't recall which, sorry.) Naturally nobody will mention that on a sales floor, as informing you would impede a sale. As for the 64 bit OS, you HAVE to have a 64 bit processor to run it. while 32 bits can fit in 64, 64 can't fit in 32.

32 bit versions of Windows can only address 4GB of memory

If you want to use more memory with a 32 bit OS you must use Linux that has a kernel with PAE support, and have sufficient hardware.

However, Windows 7 Home Premium 64 bit only supports 16GB of memory, other Windows 7 versions support 192GB
