|Do you realize we have an overclocking forum?|
If your board has the 8237 southbridge, it's the K7VT4A Pro, not the plain K7VT4A.
And the problem with VIA based boards is that there's generally no way to lock the PCI/AGP at their defaults of 33/66MHz. That limits the overclockability. The max you can increase the FSB without the PCI/AGP going too far out of spec is 188MHz...that would put the CPU at about 2.25GHz, which is a 12.5% increase.
Make your increases in small increments, do not jump straight to 188MHz. You *may* have to increase both the CPU & RAM voltage to stabilize the system. And make sure the RAM stays in step at 1:1 ratio. Since you have DDR333, it may also limit the overclock. You won't know until you try.
BTW, do your overclocking manually thru the BIOS...do NOT use a software program. And make sure Spread Spectrum is disabled.
