Hello world. Just a few weeks ago I decided to build a new system. I got all my parts together and all that stuff and now am on my new fun gaming machine. The only problem I have now is, I have this wonderful e8400 but have very little knowledge and experience of overclocking so I can't really use this thing like it should be used. I'm also a reserved person so I'm a bit scared to do anything that I don't know how to do, especially knowing the risks. I'm hoping that with the help of you wonderful and knowledgeable people, I can complete my task of OC this thing to 4.0ghz on air cooling. I have read something articles and posts and whatnot and heard a lot about the FSB and how it can raise it up, so I went into bios and changed it from 333 to 400 and now CPU-Z says I am at 3.6ghz. Just recently I've read even more and hear that FSB raises more than the cpu and am wondering what I should do and if I would be just fine to raise the fsb even higher to get 4.0 with my x9 multiplier. I left everything else at auto because I was unsure of what they all meant and didn't want to mess anything up too terribly bad. Right now, this is my system - core 2 duo e8400 PNY 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 ASUS P5Q SE/R Arctic Silver 5 XIGMATEK HDT-S963 92mm Rifle CPU Cooler I've been checking HWmonitor and it says I idle around 41c with max load at 50-55 I'm using American Megatrends Inc. Version 0409 BIOS if that matters any. Does anyone know of any good starting numbers or what exactly is important to change for OCing?
