Hardware Configuration
In addition to a 64 bit operating system, you will also need the right hardware in order to use 8 GB of memory. Both the CPU and the chipset must support 64 bit computing and be able to address at least 8 GB of RAM.
All of Intel’s chipsets since the P965 meet these criteria, as do all Core 2 based CPUs including the Pentium Dual Core and Celeron E1x00. The motherboard has to support “memory remapping”. On some boards, this feature can be switched on or off in the BIOS. However, where the feature can be found and even what it is called can vary from one BIOS to the next. In some cases, it is activated together with some of the CPU features. If in doubt, your best bet is checking your motherboard’s manual.
On the AMD side of the fence, all processors for socket F, 939, 940, AM2, and AM2+ offer support for 64 bit computing and thus 64 bit memory addressing right out of the box. The chipset does not play a role here, since the memory controller is integrated directly into the CPU.

I like the charts on the max supported ram per OS, but you need to show the user why they may need 8gb of ram, instead of "because you can" being the reason.
tsebbens' comment is pretty encouraging though. Encoding and gaming are two things I do quite often. But the fact that you can do both at the same time really a consequence of the 8GB or RAM or is it due to the processor (I'm guessing it's a quad?)?
My question is, where does readyboost fit in. I have vista home premium 32bit with a Q6600, and a 2 GB USB for ready boost. About to swap it with a 4 GB readyboost stick, will an 8 GB USB make a difference??
what more ram does is prevent Slow downs due to running low on ram so pageing happens
allso one other Point that is an small error about going past 4gb on an 32bit program it cant happen
if it gets correted an 32Bit program can only allocate 4gb of VM space even with 8gb of ram No page file would be used at all as the program can only use 4gb of space (in games i have only seen this happen on Supreme commander when there is an High amount of units on the map can use quite alot of ram or allacate alot of Vm space taht can be fixed by patching the game.exe file to make it support Large mode so it can use upto 4gb {default is norm only 2gb})
as an test on my pc readyboost makes my games judder when ever the flash drive is accessed
