2000+xp tb walled at 1.9ghz (11.5X165)

So ive tried everything with this chip to get it up to 166fsb but it just will not do it. Ive got a good power supply with tight rails(not even 3% variance. Crucial 2700 ram and the cooling is amazing ran 1.9 volts and temp never capped 35c under prime95. Im pretty sure ive hit the wall for this particular chip. Tried lowering the multiplier and raising my FSB which i got it to boot at 171 fsb with a multi of 11 but wouldnt run stable for more than 20 minutes under prime, i was hoping i could hit 172fsb with the multi at 11 but i guess it didnt wanna do it. That would have put me at my current speed actually 1892 but 7mhz faster fsb would have deffinately outweighed 5mhz clock speed. I am rather irritated by the fact that i can run 165/11.5 on 1.775 volts but cant hit 166fsb with 1.9 volts. What gives? anyone have a clue if im just hitting the wall or is there something that could be limiting me? heres my rig

If this a Palimino T-bird, then i would'nt be all upset about your overclock. What are your ram timmings? And i'll assume you have tried upping the dimm voltage? I think you have hit the wall with the CPU, but I think your ram is questionable as well.
