You would need the BIOS to be set to 8x multiplier but it may not let you make that change. You should have a motherboard with a P43 or P45 chipset and preferably not an Intel brand board to get the most out of the CPU you have.
riider has more experience with this generation of board so he may have additional suggestions.

You have to be a little bit crazy to keep you from going insane.

Install CPU-z and see what it shows as your speed.

Also you can go into BIOS set up and read the info there as well.

Your board doesn't support 1333MHz FSB CPUs. What does CPUZ tell you about the bus speed & multiplier?

Surprised the FSB speed is correct. 333MHz x 4 = 1333MHz FSB. Multiplier should be 8x. If might simply be due to Speedstep. Try testing it with OCCT & see if the CPU runs at the right speed when under load:
