How do you ascertain the clock ratio of a CPU

I have just installed an AMD Athlon 3200+ 2.2ghz cpu on a Gigabyte GA-7N400 Pro 2 mobo which supports FSB's up to 400Mhz.What multiplier should the clock ratio be set to(without overclocking) using the DIP switches? The table in the mobo manual ranges from 5x to 18x with an "auto" setting for over 18x.The previous cpu was an AMD Athlon 1800+ 1.53ghz and this worked fine at a multiplier of 11x.
In the BIOS I have set the FSB frequency at 200 which "x memory frequency by SPD" gives a resulting frequency of 266Mhz.Shouldn't this be 400Mhz? What is "SPD" by the way?
Any help would be appreciated

If your cpu runs at 2.2Ghz, then your multiplier will run at 11, same as the athlon 1800+.

SPD is a chip on the ram moduel that sends the data of the ram module to the bios, so it auto detects the setting of the ram and ajusts the bios accordingly.

spd = serial presence detect.
