Go to overclockers.com and look up the 700e. At the top of the page you will see:

Celeron
Pentium II
Pentium III
Go to Pentium III and it will tell which 700e's are cB0. Like a SL3XX is cB0. Also, I just build a PC for a friend with the PIII 700e SL3XX, an Asus CUV4X motherboard and a standard heat sink and fan. I could reach 933mhz with 1.85 volts but it was not stable on 3D games. Always remember you MUST use good RAM or memory when trying to overclock. This is why I couldn't hit 933mhz. Also you should get an Alpha heat sink and fan with Artic Silver thermal paste. This will give you the best chance of hitting 933mhz stable. My friends is running at 882mhz - 1.75 volts completely stable. Also, your milage will vary from cpu to cpu.
