Overclocking a p4 2.4C?

Hi, I'm totally new to overclocking and haven't do it before. My system specs are: Asus p4p800SE, p4 2.4C, 2X512mb GEIL value dual channel memory, ati radeon 9800 pro, seagate 160 gig, antec sx1040BX case 400W.

How can i go about overclocking my system, I don't want to overclock too much, up to 2700-2800 is good on air cooling. I already try the AI overclocking in the bios, but it had the FSB:RAM division thing, I"m not sure what that is, 3:2. The FSB was at 166, and I find it slower somewhat. What's the best way to overclock and get the best performance. I only try AI overclock to 10%. Can I manually overclocking and set the FSB rather.

:confused:

    basically, what that 3:2 division does is make the fsb for you RAM 2/3 that of the fsb of your cpu. so while your cpu is being overclocked, your ram is being underclocked. ideally this isn't what you want, you want that divider to be 1:1. unfortunately for you, your value ram is going to REALLY hold you back. you can manually set the FSB, but it sounds to me like the AI overclocking is actually doing what it should, and if you want to go farther you're going to need better ram

    Do they have a 5:4 setting in bios? Try setting that and then setting the fsb speed to around 235-240 and leave the ram timings set to "by spd" and see what it does. That should still leave the ram running within it's performance envelope and let you overclock the proc to 2820-2880 MHz, which it should be able to do without having to raise the vcore or need a better hsf than the stock retail one that comes with a retail P4.

    Yep, thats what I currently do, my 2.4 is overclocked to 3.3g (276) but the ram only runs at 220fsb using the 5:4 divider. Plus running the ram that slow allows me to enable PAT which is extra performance boost.
