Hey guys Sorry, this post may have been answered elsewhere, but I've done a bit of searching and can't find anything concrete. I've got an AMD Athlon Barton XP 3000+ cpu fitted with a Coolermaster Aero V, running on a GigaByte GA-7VAX motherboard. (currently runs at 38C @ idle, and doesnt raise much at all when playing Battlefield 2) I've got 1024 mb ram (512 stick @ PC2700, 2x256mb @ PC3200 - this is all being swapped for new stuff shortly) A new 480w PSU And a Geforce 6600GT 128mb My Mobo came with a program called 'easy tune' which is supposed to be an overclocking deely. I've run it, and I can change a few things. Looks as though the multiplyer is locked, as that's unclockonable, but the FSB can be changed, as well as voltages (I think). I've had a bit of a play, and raising the FSB raises the speed of the cpu - which is fine, but when I reboot the settings are lost. Also, I put the FSB upto 175 from 167, and the PC just rebooted - I guess this means I pushed it too far? I guess I've got a couple of questions: Firstly, can anyone point me in a begginers guide to Overclocking - I.e. what does what. Secondly, can anyone suggest how to get the most out of my CPU. Sorry for such a newbie post - I hate having to ask such lame stuff, but I'll never find out if I dont. Thanks for your time. Alex.
