@ kullymontana - what are you using for cooling?
980's oc very well due to 32nm but also (in the long run) could be a bit more sensitive to high temps and v's for the same reason.
Looks like one thing NOT to do is to drop down to single cpu, leave all cpu's running - somefolks have instantly broke their 980's doing this.
Intel max v's are vcore and vtt up to 1.4v and cpu pll up to 2v - so you have lots of head room here - provided your cooling can handle it.
also -
CPU Clock Drive-----------------------------------------[700mV] make 900mv
PCI Express Clock Drive----------------------------[700mV] make 900 mv

edit -
Re your memory settings - set you settings manually - Vddq (dram voltage) to 1.66v up to 1.8v if you have sufficient memory cooling.
mem multi at 10x for 200 bclock is good, 8-8-8-24 1T set manually and reduce timings only after you have a solid cpu clock
qpi speed is better at 20 if you can do it - performance should be better vs 16x. This will llikely require you to raise your vtt v.

Also basic question - why 200 bclock - much easier to find max cpu oc if you stress only the cpu.
Maybe take advantage of that unlocked mullti you paid for when you bot the 980?
For 4.2 something like - 30x140.
For 4.3 something like - 30x144
I bench my 980 @ 30x160 quite a bit with no problems (cooling via chilled water).
