So you will be able to run a 64-bit OS with no problems.

^^^ This one.
Also you can calculte 32bit limitation and 64bit aswell.
32bit -> calculation 32 times 2. Example : 2x2x2x2x2x... etc etc same for 64bit too.
4294967296 bytes
4294967296 bytes/1024 = 4194304 kilobytes
4194304 kilobytes/1024 = 4096 megabytes
4096 megabytes/1024 = 4GB (is usable ram on 32bit but windows will show you around 3~3.5GB)

your right to the extent of he has 4gb of ram 3 of which is usable. you missed the whole point. his 32 bit os will only allow him to use 3gb thus leaving 1gb unusable, make a ramdisk for that remaining 1gb and use the ramdisk as the pagefile thus utilizing all 4gb. so before you insert your foot in mouth again please read whole post before attempting to drop your $.02

I bet your onboard GPU is taking some of that.

You seem to not understand how memory addressing works. You can't address that remaining (approx) 512mb, even for a ramdisk. It's not possible, because the address of that memory won't fit into any of the CPU's 32-bit addressing registers. How is a ramdisk going to magically address it when windows can't even do it? (the underlying hardware can't even do it as far as windows is concerned, and the kernel controlling the execution mode is running in 32 bit) He needs to upgrade his OS to 64 bit to address that memory; period. And getting more than 8GB would abate the need for any paging at all.

Also, putting a ramdisk in system memory for paging is retarded. You would be reducing the overall remaining memory, creating a condition that requires even more paging, and the ramdisk wouldn't have enough space to page to, leading to memory shortages and crashes.

Who stuck whose foot in their mouth?
