Anyway, anyone can link me to a reliable overclocking guide so I can give that a try and so how it goes? As for the 4GB RAM, I'm as confused as you, I literally upgraded my RAM and GPU yesterday and my biggest surprise was 7 telling me only 3 of the 4GB are usable. Googling a bit read something about the other GB being reserved for other functions of the PC, but when I was only packing 2 it never said anything of the sort, so a bit dazed there.
I used to have a Athlon 64 5200x they are bad at over-clocking specially with a Stock cooler
You need Windows 7 64bit to use 4GB Ram, also if your Graphics Card has 1GB of memory, it will reduce your memory limit to 1.5GB when playing Games.
if you had 4GB of system ram and a 1GB video card under a 32 bit operating system, each individual program could only use 3GB of that system ram (due to the video card using 1GB of address space) However there is something else most people are NOT aware of.
Under DirectX 9.0C (and lower) video card ram must be duplicated into system ram. That means if you're running on the highest settings with your new shiny 1GB video card - that 1GB of video memory must be duplicated leaving you with only 2GB left for your game.
