Decided to go with ASrock X79 Extreme 6 and paired it with i7 3930k.....Having issues getting Ram to run over 1600Mhz, tried XMP 1.2 and PC won't boot, tried setting manually 1866 and 2133 still no post. Only runs at 1600, installed sticks in correct slots as per ASrock, A1,B1,C1,D1? Did not bother to flash bios because i have version 2.20 which is latest at ASrock website......Right now sticks are running at a stable 1600Mhz with timings of 8-8-8-24-1T but was informed that my Gskill Model (F3-17000CL11Q-16GBXL) should have no problems being recognized by board and run at rated speed of 2133Mhz. Never had a problem running these on my Gigabyte Z68 using XMP. What could be the issue here?

Try to reset bios and set the settings(frequency, timing and voltage) manually again. Have you overclocked the processor by increasing black?
Wait for a bios update, until then use it at 1600MHz. The speed will be the same as the timings has reduced to 8-8-8-20 when working at 1600MHz

Ram timing can be picky. If your board supports adjustments to RAM LLC (load line calibration) up it a little bit that can help stabilize memory timings

I have tried setting XMP and manually setting to 1866 and 2133 but it won't boot. Have to then clear bios, it defaults to 1600Mhz with timings of 11-11-11-28-1T at 1.605 V. My board supports both XMP 1.2 and 1.3 and shows profile 1 as being 11-11-11-30-1T if it were actually going to work. I can lower my timings down to 8-8-8-24-1T but i don't score nearly as well using MaxxMem Test as i was when my sticks were running at 2133Mhz the way they are supposed to. I have a mild overclock on CPU right now of 4.2Ghz without touching the voltage, it shows 0.906 V using CPU-Z and CPUID and shows up in bios reading 1.152 V.

Did you increase the blck or just the multiplier while overclocking? If you increased the blck, reset that to default and increase the multiplier.
1600MHz at 11-11-11-30 will be slow.
What is the operating voltage of ram cards? Try increasing the voltage in small steps.

I just did a test OC by raising multiplier to 42x, the specs on my ram are 1.65V but they default to 1.604V. I also tried lowering ram voltage to 1.5V but it just seems to revert back to 1.604V.

The voltages shouldnot revert back by themselves also the default voltages should be 1.5volts and not 1.604volts. I think you should better go and get the motherboard replaced.
