Help! Noob Question: If ram are running at 1333Mhz what frequency should the NB be?

What the title says. Basically help this noob here --> redface.gif

I am trying to figure out the optimal settings of my rig without crashes, errors, bsods or hangs.

I have C2 PhenomIIx4955 and limit for OC is 3.6Ghz, so I set bus speed at 240Mhz and Multiplier at 15.00x which defaults my HT Link to 2400Mhz and my ram at 1600Mhz. Problem is my system can't handle all 4 sticks(16Gb total) running at 1600mhz, 9-9-9-24 and 1.5v. So I have to set it lower than 1600mhz to 1333mhz, but the lowest speed after 1600mhz is 1280mhz. If Bus Speed is @240Mhz then I can only select 1280, 1600, 18??, and another option lower than 1280. However, if I set my Bus Speed @250mhz and lowering the Multiplier to 14.50x only then 1333mhz is displayed and 1666mhz something.

EDIT: It did however handle my old 4 sticks of gskills @1600 9-9-9-24 1.5v(4x2GB total).

Also should I folow the timings table of my rams displayed on CPU-Z? If so then I can go with JEDEC #4 which is 685MHz 9-9-9-24 1.50v. Is this how they are set normally?

Check the pics for more info of my system.

HT link is too high. Probably the cause. Turn down multi so link is around 2k. X8 should help. There is no gain in high ht link.
