I'm new to PC building and trying to help someone revive an old setup with an M2N68-AM SE2 motherboard and an Athlon II processor. The manual mentions that if you're using a 32-bit Windows OS, you can only install a maximum of 3GB of RAM. It also states that for 4GB or more, you need a 64-bit Windows OS. However, it also says the motherboard supports up to 4GB memory modules with Windows XP Professional x64 and Vista x64, but you can only have 2GB DIMMs in each slot. This seems contradictory to me, and I'm not sure what to make of it. Any insights would be appreciated!

It looks like the motherboard can handle a total of 4GB of RAM, but you're limited to using two 2GB modules. So, you can max it out with 2x2GB sticks. The confusion comes from the 32-bit and 64-bit OS mentions; essentially, if you stick with a 32-bit Windows, it won’t recognize more than 3GB, even if you have the hardware to support it.
Yeah, I've seen that in the manual too; it can definitely be a bit misleading. Just remember, to fully utilize 4GB, you need a 64-bit OS, and installing two 2GB sticks is the way to go. The specs in manuals sometimes don’t make it super clear, especially for older tech.
