P4 2.4B Overclocking Questions

[xmyxgiantx]

Hey guys,
I have a few questions for you.

First of all:

P4 2.4B
MSI 845PE Max
512MB ValueRAM PC2700
350W Power Supply (I am getting a new one next paycheck along with more RAM)
Zalman 7000A Cu Heatsink
4 Vantec case fans

Processor:
Idle Temp: 30C
Load Temp: Mid 30s

Case:
Idle: 29-30C
Load: Low 30s

Okay so right now I have upped the FSB to 145 and 149 with voltage at 1.525V and AGP/PCI at AUTO, and everything was fine - the temps were still at 34C Idle and just about 40C Load . I ran Prime95 for an hour with the FSB set at 149 and no problems with a max cpu temp of about 44C.

Although I noticed that boot times were taking a bit longer I thought, and also when I upped it to 156 and set the AGP/PCI to 66.07/33.03 the boot time took forever. So I set it back to AUTO and it ended up not booting so I cleared the CMOS and started over.

Questions:
1. Should I up the voltage a bit? .25? .50? How much? (Remember 350W PS)

2. Is the 66.07/33.03 setting correct for AGP/PCI?

3. Also, why would it take longer to boot when its overclocked?

Thanks!

I have an msi 655max board with the 2.4b and the board is undervolted. Try raising the cpu fsb to 150 and the cpu vcore to 1.52 or 1.55, and see if the board will run stable. Set the memory to spd and normal for timings. Msi boards aren't very stable when overclocked, but 150 is a pretty safe setting for the 2.4b. I've tried 5 different chipsets with my 2.4b, and none of them ran stable above 150. 66/33 is correct for the agp/pci setting. Don't know why it takes longer to post when you overclock. Just be sure your bios is set to "fast boot".
