Put everything on default again and start over.
Find your stable vcore first, leaving the Dram @low speeds.
When you find the vcore your stable vcore (5 hours occt or something like that) then move on 2 the memory.
you must up your vvt SLOWLY till it becomes stable.(as i said normally u use vvt 1.3-1.4v for 24/7 but you MAY need higher vvt to stabelize @2000Mhz dram speeds)
Never use cpu pll above 1.8v because it will do nothing or near to nothing (in my exerience)
Your ioh/ich voltage and analog ioh is also to high. near stock should be enough when using 200blck
your ich 1.5v is also to high. i think you could leave it @ stock also.
The dram voltage you can set @ 1.665v if your mem modules are rated 2000mhz 1.65v
you can leave qpi frequency @ auto if your not going higher than 200 blck.

The most important thing off all is that U MUST Read alot to learn about the voltage settings and other settings so you know what you are doing. I gave you a link a few post before and i think it would be good for you to read the topic through. You'll learn alot. Also the first dfi x58 topic here on XS will be great. Maybe some other overclocking guides etc. etc.
Because if you use the voltages the wrong way you'll get instabillity.

hope this will help you!
