Get the answer kaweee November 15, 2011 11:22:43 AM I'm not too sure about why but it seems like an OS limitation Games shouldn't take too much ram so I wouldn't worry about it m 0 l jsc a c 156 V Motherboard November 15, 2011 11:58:00 AM Memory management is a pretty complicated subject, but basically a 32 bit operating system is built around an address space of 32 lines. 2^32=4GB. But it is worse than that. Intel CPU's use memory mapped input/output - devices are assigned address space that then cannot be used for memory. The end result is that you generally have around 3.25 - 3.5 GB RAM available. 64 bit OS can address 2^64 or 4GB*4GB or a bunch of RAM, well 16 exabites (16 x 10^18). Limitation is generally the motherboard. m 0 l dannny November 15, 2011 5:56:09 PM thnx kawee & jsc jsc what do you mean by motherboard limitation? do you recommend me to upgrade to 64 bit? m 0 l kaweee November 15, 2011 9:45:43 PM Just stick with 32bit, your programs will run absolutely fine. m 0 l Can't find your answer ?
