Processor speed vs. mobo ram speed

[DrBEN]

Generally, if mobo compatible RAM is rated at a higher speed than the CPU speed, will the system simply run at the maximum available CPU speed? In other words, is system bus speed limited to the max speed rating of the CPU?

For example, Intel rates i5-6600 at 1866/2133. If the mobo RAM is rated at 2666, will the system force the RAM to run (with no problems) at the max CPU speed of 2133?

You should be able to freely adjust the RAM speed in your BIOS settings. It usually defaults to the rated clock rate of your RAM.
