Anyone help me?

Just at last time, i have OC my celeron 433 to 540,and it is stable(never change voltage).But i cant choose more in my bios.It only can stand in 540.
Here my questions:
How can i make it more?
How can i change voltage?
Is it enought for Intel fan?
MyPc :Celeron 433@540mhz,192 ram(one 128,one 64,pc133)Gerforce2 MX 32m,IBM 15G,
Mothernoard,Eagle AP1-693A(Apoller pro 693A for north ,Apoller pro 596B for east.)

I'm going to venture a guess that your motherboard is what is holding you back.

I just replaced my A-Trend mb, which had the same VIA Apollo Pro 133 chipset as yours, with an Asus, running the intel i820 chipset.

You don't mention, (and I'm not familliar w/ that motherboard) is it a slot 1 or S370 board, and do you have the option to change the core voltage setting ? Also, what are you using for a heatsink and fan?

You mentioned you haven't changed the vcore. This might be holding you back. It's also remotely possible that you have "hit the wall" as far as going faster with that particular chip. Not every chip will overclock the same, examples, my two cC0 Celeron II 600 chips.

One maxes out at 945, the other at 1045 MHz, and is showing indications, that with a bit of effort, might even make 1062 MHz. These chips are six weeks production apart, with the same "S" code, from the same plant (Malasia).

The problems I had with the Via chipset was memory bandwidth scores I was getting in SiSoft Sandra. Absolutely horrible.....I was getting lower scores with 320MB ram than a "similar system" of a Duron 600 w/ 64 MB ram.

Not good.

Also worth noting, my Celeron 600 that now runs 1045 on the Asus, would only hit 1009 on the A-Trend. I haven't changed the voltage, just the mb.....picked up 4 MHZ of FSB (x9 multiplier = 36 MHz proc speed).

Something to think about......
