I am a few days from receiving the last piece of the puzzle for my first homebuilt PC. I'm excited to have it done, but I am working on a budget so my processor is underpowered. I have heard from various sources that my processor is capable of a nearly 100% overclock - obviously, this interests me, because a dual-core 3.0GHz chip = perfect for my computer needs. I have: nforce570 Slit-A motherboard. Intel E2140 Dual-core processor. Allendale core, 1.6GHz. 2GB DDR2 PC6400 memory, 5-5-5-15. 1) I know that the chip can handle a 40% overclock on the stock cooling fan (all available sources agree - this degree of boost only produced 1*C for several different people). Were I to leave it at this degree of overclocking, would it be necessary (or advisable) in the long run to improve my CPU fan or case circulation? 2) One of the how-to guides I saw online mentioned needing to change the memory "timing" in the BIOS. What does this accomplish in regards to overclocking? 3) Just how difficult is this process, anyway? Is it more a matter of getting past my fear of tinkering and just doing it trial-and-error, with the stock settings written down in case things get totally fouled up? Or should I leave this 100% to someone who has done it before?
