Hi,

The specs of Intel i7 4930K says that the memory type supported is 1866Mhz. I wanted to know if Gskill RipjawsZ F3-2400C11Q-32GZM which is 2400MHz will be compatible with this CPU?

I think you're right, though I did read that the more you deviate from 1.5Volts for the memory the higher the risk of damaging the memory controller is over time.

I wish we could get reliable information on all this, though generally I guess just not worry about it. Again, just click "XMP"...

Look at the MOTHERBOARD site.

For example, my i7-3770K states 1600MHz max in stock and I get 2133MHz (when neither the memory nor CPU is overclocked). WHY? I'm assuming that the motherboard has its own memory controller that gets used instead or else it makes no sense.

When I look this up though it seems that my motherboard isn't supposed to have a memory controller, only the CPU. So it's listed as 1333/1600MHz but gets 2133MHz when not overclocked?

*Long story short, just click "XMP" in the BIOS and it probably will default to the optimal DDR3 settings for you. If you overclock the CPU manually though you may screw with the memory settings so pay careful attention to that. And of course run MEMTEST www.memtest.org

the mobo does not have its own mem controller, the reason is that intel doesnt want to get in trouble when they list 2400 support and there is a few cases of that not working, so they list 1600 as compatible, but the i7 4930k should work with 2400 ram almost all the time, with no overclocks.

^^ exactly, which is why intel only lists support for ram up to 1.575 volts, higher than that and intel doesnt want to risk it, however the cpu's are tested up to 1.8 (i think) and the mobo up to 1.7 (i think) for some headroom for slight defects, so 1.65v ram should works unless you got a cpu that passed the absolute minimum test of 1600, but has some slight defects that only let if to to 1600.
