can a 32-bit OS machine use up all 8GB RAM + 20GB page file?

I understand that I will not be able to use a full 4 GB on my 32-bit Windows 7 installation. I ready have two gigs installed on my machine and a friend just gave me another two gig stick. So what can I do with the memory that is above the Win7 "limit"? A RAM disk? Faster/better video? Nothing?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Take a look at this… – HackToHell Apr 25 '12 at 14:45
Windows will be unable address anything beyond 3.2GB of memory. The rest of the address space will be used by hardware. I won't bother with providing a more detailed answer, this has been asked a million times, and there are a million and one accurate answers. – Ramhound Apr 25 '12 at 14:45
@Ramhound I guess you missed this W7 – Moab Apr 25 '12 at 17:50

Memory above the limit is unavailable, so you can do nothing with it.

Unless you would enable PAE, such that you can access it just like the other memory is accessed, such that the limit is gone. But that slows down memory access a lot...

You can't use it for anything, as far as i'm aware, unless the operating system can see it (which it can't). I believe the actual limit is 3.2gb, so you'll only be losing out on 800mb.
