After having purchased the CULs2 Assus mother board and the 733flipchip p-III for the purpose of overclocking. I am being told that I can't over clock much faster than 800mhz.
I have an Alpha fan on the cpu a case fan and a slot fan on my video card and I have just change my power supply from 250watts to 300watts.I have 256megs of 133bus dims mem. This board works jumperless so I can't change the multiplier I can change the bus speed. However it suggest that if trying to overclock bus speed over 145 set pci frequency to 133.100.33 rather that leaving it at 133.133.33
What is my limit with what I have as far as overclocking is concern.
Should I just buy a 700mhz with 100bus and cas 2 on the chip and overclock the Bus speed to from 100 to 133 which should bring me to around 933mhz?

Any of the EB chips, of which the 733 is one, are much tougher to overclock and make greater demands of the system hardware. The 700E is possibly the easiest to overclock and 933 is not uncommon at all, with many going to 1 GHz without difficulty. If you have the option of changing from the 733EB to the 700E it will definitely simplify things for you.

Thanks! Do you know if I can overclock what I have at all?

Depends on a lot of factors- peripherals, memory, etc. You might look at the cpu database on the opening page and see what kind of luck folks have had with that chip, and what it took to get there.

i had a p3 733 on a CUSL2-C. the highest i could get it to go was 919@167fsb with the PCI screaming at 41+mhz. u have to set it at 133.100.33 unless u have pc150 ram (not tried tho') my micron pc133 wont run at 166+mhz. it was fairly stable but really not worth the effort (heatsink mods, fans etc) coz of the low multiplier at 5.5.. so i gave it to my sis =P and got a p3 750 which went 1005 easily after some burn in. Tim is right, it depends on alot of factors chip batch, vid card, hd, etc the only way is to experiment.. gd luck =)
