Overclocking P4C800-E Deluxe

Alright, well this is my first post on the forum, so I'd like to say hey to everyone first. Hey! But yeah on to my question, I'm like completely new to this overclocking thing, but I got a lot of high quality stuff in hopes that some day I would overclock it and that day has come. But I don't know how to do it. I have the P4C800-E mobo, and I know how to go in and do the AI overclock in the BIOS by like 10%, 20% whatever(but that drops the memory speed down so that's no good), but when I go the manual setting and try and change the FSB, I can't, it won't let me up the value any. Do I have to press a special button to get it to work or what? I can't hit enter and change anything, can't use arrow keys, nothing. What do I do? Also, my memory is supposed to run stock at 2-3-2-6, but when I set it to run by SPD in the BIOS it's running at 2.5-3-2-6. When I try to manually change it to 2-3-2-6, I exit the BIOS and the screen goes black and I can't reboot into Windows. It just stays black after reboot. I have to do the hit INS trick to get it to load into the BIOS and it keeps saying some message about OC failed. I tried OCing by using Clockgen and it was only stable up to about 220MHz FSB, at 225 programs were crashing and at 230, screen went black and computer cut off. Please help.
 
1. To increase the FSB, hold Shift when you hit the + key. Without holding shift, you can only lower it (with -).

2. SPD didn't work for me either, I had to manual set mine to 2-3-2-6. If it wont boot at those timings, experiment with raising them. Maybe 2-3-3-6. Or 2-3-3-8. You shouldn't have to change the CAS latency, but you might bump it up to 2.5 if you still have problems.

I haven't had much luck overclocking this board. But I haven't pushed it. I don't want to risk upping the voltage, as I don't have terrific cooling. I was running my 2.4C @ 3.0GHz with a 5:4 CPU:FSB ratio. (Changing where it says 400 in the BIOS to 320). I think that worked very well. Some people here are sure to tell you to keep at at a 1:1 ratio though. It's up to you.
 
Alright I managed to overclock the FSB to 220 and it will boot, I tried 230 and it didn't boot at all. So I've got a 3520 MHz core and 880MHz FSB. I can boot my manually setting the timings at 2-3-3-6, but not any lower. A strange thing is I can't boot by setting the RAM speed, if I put it at 400MHz it won't boot, but it will under auto. The bad thing about that is it's making the memory have a 3:2 timing and I'm only running at 292MHz on the RAM. I have Corsair XMS 3200LL-Pro, that stuff is supposed to be able to run at over 400MHz, at least if I paid 315 for it, it better run over that.

Oh yeah by the way on the CPU I've got the Zalman CNPS-7000A-Cu which is a better good heatsink, so I should be able to go farther, but I can't.
