arre mask u have one of the the best ocing athlon ever - 2500 barton..y r u complaining????..i think u can easily go higher than 2225 mhz by lowering the fsb n increasing the multiplier...forget the **** about higher fsb=higher overall speed....185x12.5=2312 is definitely faster than 200x11=2200...check it out in any benchmark...sisoft..pifast..pcmark..
hey mask do u use both ur ram dimms while ocing??...ie (i think u have 256x2 ddr500??...really envy u man!!)...just use one 256mb dimm.....cause i have heard of cases where dual channel really drags down the oc....i do the same thing...just one 512 ddr400
btw i forgot to mention a very imp. thing....the oc i have achieved (2312mhz) is with just 1.55 vcore ...

...n tested with 12 hrs prime95...so the best is yet to come...
