You may need 1.6 to 1.65 Vcore to get it stable at 11 x 200. My M-2400+ needed 1.625 to be perfectly stable under Prime95 at 11 x 200. If that doesn't get you stable, try bumping up the voltage on your BH-5 just a bit to see if that helps, but it should be able to do 200MHz at those timings with about 2.6V. Good luck!
