Accessing more than 4gb from a 32-bit OS.

[Ease]

I've also "known" (as far as I can tell) that a 32-bit OS has a limit to the amount of memory it can address, which people consider to be between 3 and 4.2gb. However, a colleague at work is currently insisting that his 32-bit OS at home can access all 16gb of his memory. He couldn't clearly explain how, but insisted that there was a workaround. I was hoping one of you OcUKers could help me.

One more thing,

How does he even have 16gb of ram?

Max you can get is 12gb. That's 6x 2gb.

Unless he managed to somehow get 4x 4gb which cost tons.

He has 4 x 4gb sticks, and yes, he spent over £2000 on them (it was a fair few years ago now) - I would LOVE it if I could somehow prove to him that he's completely wasted his money, but he's very stubborn and ignorant, and wouldn't let me within 200ft of his computer if he knew my intention was to prove to him that he's made a massive mistake Unrelatedly he also insists that your 'real' downstream bandwidth is ALWAYS one eighth of the advertised bandwidth... when I explained he was just converting from bits to bytes he shook his head and said that he was already talking bytes. It's a shame to know that people are living under falsehoods, but some people are impossible to correct/enlighten.
