What's the maximum CPU upgrade for my old Jetway BX133 board?

The old manual says up to 600Mhz Pentium III, but I'm hoping it will take something faster. The board can take either a Slot-1 or Socket 370 CPU and currently is running a Celeron 400 (Socket 370) chip.

The board is based on a VIA VT82C693A Apollo BX133 chipset. The manual gives the following jumper options:

CPU Freq: 66 - 150MHz
Ratio 2.0x to 8.0x (in 0.5 increments)

Going by those numbers 8x100 = 800Mhz or 8x133=1064Mhz, I'm guessing it would take up to an 800Mhz Celeron or 1GHz P3. Am I close?

What I don't know is the voltage settings of the chipset or those CPUs. Does anyone have any ideas? (The board was designed for PII-266 to PIII-600 chips, so what type of voltage range would that be?) I want to avoid buying a Slocket/Slot-key or Powerleap, if possible.

Thanks for your help.
