ssd is on the list already but ty. so what is the highest speed frequency i could get on an lga 1155 you think because im getting an i7 2600k im thinking
"OC" means that something is being run outside the maker's specs. I think that Intel, for example, only officially supports up to DDR3 1600 on Socket 1155. (I'm running 4 X 4 GB of Corsair Vengeance DDR3-1866 on an Asus P8Z68-V Pro board at the rated 1866 MHz. RAM timings are set manually.) I haven't run DDR3-2133, but I expect that it would work. (It would require setting up the BIOS properly. Plug & Play would default to DDR3-1333.) If you want to try DDR3-2133, why not go for it?
When I said that some believe that there's no such thing as quad channel RAM, I meant that the belief is that there are no differences between the DIMMs in a quad channel kit and the DIMMs of the same ratings sold individually (or in dual channel, or triple channel). I'm agnostic on that - I don't know enough to have an informed opinion.
I'm not a "3D developer", so I can't advise you based on personal experience. The Socket 2011 board support quad channel RAM, and (in principle) the highest available memory bandwidth, but apparently that's only available to applications that support multithreaded memory access. I also can't tell you whether you'd gain much with fast RAM on a Socket 1155 system. For common applications, the faster RAM frequency is sometimes offset by increased latency (delay) as compared to lower frequency RAM.
Some motherboard makes publish qualified vendor lists for RAM. Asus, for example:
ASUSTeK Computer Inc. -Support- Drivers and Download P8Z68-V PRO/GEN3
Alternately, see whether the RAM maker certifies their memory for the motherboard of your choice.
