When my system boots up, it reads that I have 2555 kbytes of memory when in reality, I have 4.0 gig installed. I have Corsair Ram that is supposed to be "gamers" ram which I am supposed to be able to overclock or tweak. I have done nothing of the sorts to date. I am under the impression that XP Pro 32 Bit, only see's or can actually use 4 gig of RAM, is this true? Why in the bios on my screen does it report less than what is actually present? Also, is the machine taking full advantage of the 4 gig that I have or is it a waste of memory? I do some video transcoding on the machine, which takes forever, but I also understand this is an older machine. I have an ATI Radeon 9600 video card with 256 emg onboard memory. My 16 year old has a quad core system that smokes mine, but he's always on it and it is his to use so who am I to say otherwise, besides his father, giver of life and food? heheh I included my system information hoping that might help answer any questions you may have about the system configuration. All drivers are current as well as the latest bios available.. what's a poor fella that can't afford an upgrade at this point in time to do? Is the system using the resources that it has to the best of its ability or can I somehow change some settings so it "works" faster? Many thanks for the advice!
