There is a change in FSB frequency from 400 to 533 during the production of Pentiums 4 cpus. My info says 1.6 1.8 2.0 and 2.6 used 400 Mhz and 2.4 2.8 used 533 Mhz. I can't find any information from Dell on what the Bios updates might fix or if your motherboard can even work at 533 Mhz. I did find this info from a memory supplier that listed the Dell model number with 533 FSB:
A few of the 8200s have a motherboard which will support a 533 front bus speed, these can use the PC1066 RDRAM. When in doubt, give us a call at 1-800-566-3727 to help you determine exactly what you need.

Do you know if your CPU has a Northwood or Prescott core? You might have picked up a Prescott core, and your motherboard may not be compatible with it, after all, it is a Dell.

Much reading scraped some of the crucial details:
To install CPUs with the 533 FSB, the 8200 board must have both the Intel 850E northbridge, and 40ns memory installed (not 45ns, tho it doesn't seem to care if ECC or not - I'm using PC800-40 ECC with no issue.) Some boards have the 850 northbridge - this is not capable of 533 FSB. The CPUZ utility, and others, will report this crucial detail.
