|Although you don't have to really 'overclock' anything, basically just have to manually set the RAM to run at 1866 MHz in BIOS. |
Riider is correct, you should be able to use the first set you posted above (post #6), although the other two, being 1600 MHz, you would either have to run at 1333 MHz or overclock them to 1866 MHz (in this case it IS overclocking, as you are pushing the RAM beyond it's factory limits) which may or may not be possible, I'd have to do more research on your mobo.
But yes, you should always be able to run RAM at a lower speed than it's factory default.
