I have a Shuttle SG32G2 PC that I'm using as a small home server. It has two 240-pin DDR2 RAM slots, and officially supports 2GB per slot, for a maximum of 4GB of RAM, which I already have installed. I'd like to upgrade it to 8GB, using two 4GB sticks, however I've never tried installing more RAM than the motherboard officially supported, so I don't know if I'd be wasting my time or not.
Has anyone tried installing more than their motherboard's supported amount of RAM, and if so, what was your experience? Did it work? Did it render your PC unstable or unbootable? Did you run into issues that you were able to work around?
And for bonus points, if it won't work, why won't it work?
