32BIt OS

zxzlenin · 07-07-2008, 07:07 AM

Just wondering since i plan on upgrading my 8600gt 256mb to a 512 or more video.
I keep hearing 32bit OS use 2GB or 3GB of ram max.

So lets say i have 2GB of DDR2 ram and buy a 512mb Video making it 2.5gb of ram would i need a 64bit OS to use it my video card to optimize performance?

Or is that 2GB/3GB ram limit on 32bit OS is only for Physical RAM and does not have anything to do with video memory?

32 bit OS can map up to 4GB of memory, of that your videocard will talke up 512MB, other things take up additional mapping so once you get over 3 you begin to run out of useable memory. It's there but off the map so the OS does not know to utilize it.
