umm i think windows 7 32-bit supports only 2GB of ram??
No...It is up to 4GB, which is why I was confused...umm...64bits can take up to 8GB ( or more..?)

A 32bit OS can only address 3.25GB of memory... nothing is wrong with your system...

There is also an app from Sysinternals that might prove graphically helpful.

32 bit Windows can address a total of 4 gig of ram.

That 4 gig is used for prgrams as well as memory space needed by various pieces of hardware.

Typically you end up with between about 3.2 up to 3.8 gig free for software use depending on hardware configuration, but can be even less. An individual program on 32 bit windows can only address up to 3 gig of ram at most. (But of course multiple programs can fill all available ram if necesary)

In 64 bit Windows, the hardware still needs memory space but since 64 bit windows can address 64 meg or more (Theoretically it's insanely higher than that but there are some aritificial limitations) the base address for hardware is moved way up above installed ram to not sit on top and waste any of it. Some older motherboards may not allow this however...

So should I just go with 64 bit windows instead of 32bits? I just installed 32bits onto my computer so 'An individual program on 32 bit windows can only address up to 3 gig of ram at most' is that why it is only showing 3GB? I had 64 bits and it always showed 4GB total & available...The only reason I am using 32bits is because Spyware Terminators real time shield does not work on 64 bits windows...( am I losing any performance going from 64bits to 32bits?)

Hey SF, I'm in need of a RAM stick that will work for a Dell Dimension 2400. Anyone know where I could get a cheap stick? Or anyone have one they could part with? Prefer 1gb but beggers can't be choosers. Currently the DD2400 only has 256mb of RAM. :S Thanks, Steve
