750i FTW & OCZ Reaper

hey guys finally got this thing up and going haha but n e way when i first boot my pc it registers i have 4gb of ram (which is right) but in windows it says i have 3gb under my computer and under alienware dock station it says i only have 2gbs... i was woundering how to fix this?

Things I changed in CMOS:
Timing: From 5-5-5-15 to 5-5-5-18 (thats what stock spec is)
Volt: From 1.29v to 2.1v (stock spec again)
mghz: From 800 to 1066 (again stock spec)

my system specs are correct...

I just downloaded the drivers off the EVGA website and installed them for my mobo..

thanks guys!

Its XP32 bit, it can only read up to read 3GB

An OS such as windows XP 32 bit, actually can address exactly 4 GB of Memory. But in that 4GB of address space, it also has to include the space to access the system BIOS. So that space cant be used as RAM. And at the same time even the video bios has to be addressed, and again it is cover inside this 4gb address space, so it further decreases the RAM addressable space, also the bios essential for all other devices which are connected. Even if your GPU has onboard video memory, its addressing has to be done within the allocated memory space of the OS i.e 4GB incase of XP 32 bit. I see that you have a GTX 260, so 896MB of RAM space is already preoccupied. You can isolate GPU memory so that it frees the CPU address space, but it will drastically hurt the GPU performance. So if all your RAM+ GPU ram + bios address space was less than 4gb, then all your ram would have been fully utilized.

So if you want to make full use of that RAM, you will have to switch to a 64bit edition OS like XP 64bit or Vista 64bit. Ofcourse there are versions of 32 bit Windows (Server versions) that can use more than 4 GiB of memory by using a technology called Physical Address Extension (PAE), but that's a radically different area, you are better off installing a 64bit OS rather than this. If you are into gaming, then this transition makes a lot of sense. So go ahead and get 64bit Vista or 64bit XP.
