There are some issues with 440GX and 440BX chipset motherboards and processors
faster than 600 MHz. See
http://www.supermicro.com/TECHSUPPORT/FAQs/Processor.htm#Question 3
Your P6DBE's are 440BX and therefore affected. These issues include only
being able to handle 100 MHz fsb, bios compatibility with Intel's newer
microcode, and lower core voltage on the 0.18 micron substrate; some of those
boards have the Harris HIP6004CB or HIP6004ACB voltage controller which won't
work. If you've got the HIP6004BCB or a Cherry CS5155 voltage controller
they'll provide the proper voltage for the thinner substrate, but you've
still got to check the bios BEFORE you put the cpus on the board, and
still can't use 133 MHz fsb processors. One or more of these bugs got to me a
few months ago, and our supplier ended up getting us Intel boards instead. Good
luck.
