From What I've gathered, by default 32-bit systems will not recognize the 4GB of RAM, rather it would only recognize up to around 3GB of RAM. My question is simple, will there likely be a performance hit of any sort if I proceed in using the 4GB anyway? I don't mind not "maxing out" the 4GB – just as long as there won't be any significant performance and stability issues I'll be more than happy. I ask because I have a 2 GB stick lying around and it's a shame not to use it.
Thanks for the answers in advance!
