CPU: Intel® Core™ i7-5960X Processor Extreme Edition
RAM: G.SKILL [Ripjaws 4] F4-3000C15Q-16GB

1- in bios setup program, my ram speed is 2133 but my ram speed is 3000. whats the reason ?
2- if i need to add 32GB 3000 RAM, does this system (especial my CPU) support 8 ram (4x4 & 4x8) ?

thanks for your attention

That's the default setting for Haswell-E. Under Extreme Tweaker in the UEFI, under Ai Overclock Tuner, you can change it to X.M.P. By default, this is set to Auto.

Best practice is to get matched 32GB RAM kit like 4x8 instead of buying of 4x4 kit and then add another 4x4 kit (or 4x8 kit) later on. Each kit has been thoroughly tested.
