I have a question pertaining to memory standards.

DDR3 3200(OC)/3100(OC)

When choosing ram for this board What information does this tell me? Is this the max mhz this board will run overclocked? I was a little confusd by the (OC). What ram would you get to do this setup justice? Corei7 4790k CPU.

The (OC) just means that the memory will not default to those speeds, even though it is capable of running at them. To run at those speeds they have to be manually set in the Bios (along with the appropriate timings). They are not the maximum speeds for the memory, they are just what the manufacturer specs (ie guarantees). The memory may or may not be capable of higher speeds depending on a whole lot of other things, not the least of which is your overclocking skills.

As an aside, memory specifications are established by the JEDEC, which is a standards body for the global semiconductor industry. The highest DDR3 memory spec they have issued is for DDR3 1600 mhz memory. So, "officially" any memory spec'd over 1600 mhz is overclocked.

this is the specs of supported memory speeds with that board.

Basically it means 1600Mhz is the only memory guaranteed to work. anything above that is AN OC but should work, normally the limitations lie within the CPU IMC

I have 3 CPUs for my current setup I went for the lottery 1 chip will do 4.7Ghz with 2400Mhz memory the other 4.6 with 1866 Memory the one I am running will do 4.8Ghz with 2200Mhz memory, all tested in my sig motherboard.

Put it this way I have 2400Mhz memory it is Guaranteed to operate at these speeds they will do 2400Mhz with 1 out 3 chips I have. I now have under clocked to suit my CPU
they are rated to do 2400Mhz @ 10-12-12-31 2t, I have clocked them to 2200Mhz @ 9-10-10-24 1t I tightened the timings to compensate for the CPUs weak IMC
