@Fizur2002:
You must check/set your DRAM-speed to manual to verify the current "divider".
At present you have no control over the resulting DRAM-speed vs HTT(FSB).
Since you've got a 940 I see no point in "fiddling" with HTT(FSB).
Just let everything exept VCore/MP be "Auto" to find the OC-potential for your "chip".
