I would also like to know about overclocking latencies. I have them at default. How low would I be able to lower them and how much is the speed gain when going to 1866mhz in modern Intel setups? So lets say I want my latencies to around four. How much voltages does is need or is it even possible to lower them so much? I do all kind of things from coding in visual studio to creating 3d and making video games.
I have searched google and no luck.

Overclocking memory yields far less (relatively) that OCing your CPU or GPU. The consequences of doing so (OCed memory) is often an unstable system.
I would recommend you keep your memory at stock speeds and focus on the other components of your system.
Stability trumps a small increase in performance any day of the week.
