So I tried raising my FSB to 200. No go. Then I tried raising my voltages to compensate. No go, even up to 1.850! Not like it would matter if 1.850 did the trick, my CPU was running at a not so cool 71C. I'm using one 512M stick of Kingston 3200, so what's the problem? Does my CPU just not cut it?

If it's a desktop Barton 2500+, it may not be able to reach 2200mhz stabley. Mine seemed to crap out at about 190mhz. I couldn't go that high on the voltage though. Didn't have good enough cooling. Your chip MAY be able to reach 2200mhz, but I would question whether it's going to be stable at that temp anyway.

Try to work your way up to 2200mhz, and perhaps you need better cooling.
 
It may be the CPU or Motherboard. There's not much that can be done if it's the CPU. What revision is the MB? 1.0x versions had some trouble getting to 200MHz FSB, and the best bios for them was 1004 or 1006. Whatever version the board you have, try different bios versions and see what works best for you. Peace.
 
I also had a desktop 2500+ that would not make 200 FSB. The latest desktop barton cores are not as good as what was being put in the desktops a year ago.

My older 2500+ works great at 2200 with a small voltage increase.

I wouldn't be surprised if it were your processor, nor would I be surprised if you have an A7N8X that can't make 200 MHz FSB. Regardless of which is limiting, the procedure for finding the best overclock is the same:

Start around 180-185 and run Prime95 for a while (several hours). If it's okay turn up the FSB 2 or 3 MHz and do it again. repeat until you can't get higher, then back down. If you end up with different max FSB with different CPU voltage, then your CPU is limiting. If you're always maxed at a particular FSB speed regardless of CPU voltage, then your mobo is limiting.
