Front side bus speed on CPU Celeron D331 2.66GHz 256K LGA775

the front side buss is correct. most motherboards will read 100 or 133 or 200 etc on your FSB because thats the pre multiplier of FSB before it equates to 800/1033/1633/2000mt's etc like for example a amd athlon 64 3700 on a socket 939 has either 1600mt's or 2000 mt's for the FSB and it reads on the motherboard as 200 mhz and the multiplier is at X10 times the multiplier by the MHZ ratting and you get 2000 mt's now your cpu's FSB is 133 mhz and your multiplier is between 6.0 to 6.1 and it will be reading between 798 MHZ to 811.3 abut will not say its running at either on of those speeds because if it was at X6 then it will read at 800MHZ for your FSB so everything looks to be correct. there is nothing wrong with the cpu nor how the MOBO reads it

According to the spec's this motherboard has FSB speeds of 800+3.

Here is a link to the page I found stating the spec's for you.

I have read reports of this motherboard having problems though. You might need to get a little better motherboard.
