Problem with new ram

That simply means you are using a 32bit version of Windows

To make use of all 4GB , you need to upgrade to a 64bit version

thanks kaweee

okay but why so in 32bit version of windows?

when i play games then how much is utilized?

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

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.

thnx kawee & jsc

jsc what do you mean by motherboard limitation?

do you recommend me to upgrade to 64 bit?

Just stick with 32bit, your programs will run absolutely fine.
