With speedstep enabled, Realtemp will report varying multis depending on background activity of computer ie cores active vs not. CPUZ reports constant multi with speedstep enabled, ie does not seem to work correctly with speedstep enabled. If you disable C1E and EIST, then both Realtemp and CPUZ should report a stable multi.
