Higher FSB with P3V4X

[The Joker]

I'm using an Asus P3V4X with a Celeron 633 and 256MB PC-133 RAM. The max FSB that I can get it to boot up at is 75 MHz. Anyone know why it wouldn't boot at a higher frequency or what I can do to get it higher? I'm pretty sure I should be able to run this chip faster then 714 MHz. Thanks...

did u try upping the volts what cooling do u have

Yes, I have tried volts up to 1.85 with no luck. I am using a Golden Orb fan. At 714 with zero CPU load it sits at 28 C. When running at 100% load it will get up to 45 C.

My friend is using your board and he related to me that if there is a problem overclocking its because of the auto voltage regulator on the mb. Instead if you would have to change the voltage on the slot adapter hopefully you are using the asus cl370 or the newest asus. then it will detect it at that voltage and you could then adjust the fsb to the 100 you want. Your success will improve.The problem I believe is that when you reboot it will revert back to the auto voltage. This he said was the main advantage of your board over asus's cuv/4x socket 370.Because it can by pass the boards fail safe to revert to the auto voltage which would explain why you can't overclock higher.Also if your cpu is a cbo i believe its 1.85,while the cco has a lot off sucess at 1.75

hmmmmm....strange, i didn't have a voltage problem on my P3V4X when i had it even without a voltage changeable slotkey. I switched my p3v4x for a ABIT BF6 and now have my Celeron II 700 @ 1015 2.2v no games, but 956 2.1v games and stable.

Also sounds like high temps, @ 2.1v i dile @ 21C and full load @ 37C
