> 32bit Windows still recognises 4gb of RAm, it just won't use it for Windows... though it does use it as a ram drive for other programs that are built to support extra memory
No, you really can't use the last 500mb/1gb of RAM in a 32 bit system - the actual memory addresses are assigned to VRAM, other system devices, etc. so any physical RAM you install beyond this point will go completely unused.
Yeah it's a limitation of 32 bit architechture. When I said it uses it as a ram drive, I meant it will allocate it to things like virtual memory, vram, and system cache. It still "uses" it, but Windows doesn't "use" it.
Also, I have experienced lots of crashes with opening cap files on my big rig, but only when SLI is enabled. If I turn SLI off, it will open without a hitch. Weird.
