Mark your CPU core volts are pretty high, you could try a NB volts bump to see if the would help. If it is possible keep the HT link around 2000MHz.
I've got the CPU voltage as low as I can. Any lower it won't boot (the NB is pretty high as well) I think I just got unlucky with this chip and I'm waiting for Pile Driver chips before I upgrade
Intel® Core™ i7-2600K Processor
Your Tcase max temp is 72.6°C. add 5°C for core temps, your max core temp is 77.6°C.
You will see many OC sites going way over this, so it is a conservative number from Intel.
Have read where Intel can get info from the CPU for the max temp it has been ran at, if the warranty is ever needed.
Evidently they don't use that to void the warranty, according to some posts.
Motherboard auto voltage is notorious for over-volting.
You should always manually adjust your CPU voltage when OC'ing.
Back it down until it won't pass Prime95 or IBT.
1.584v is very high, you should be able to get around peaceful's 1.368v, or lower
