So after many, many hours testing for stability I have finally found my stable overclock (Thank you Earthdog and trents)
At one point I even had my vcore up into uncomfortable territory (1.42 for me) looking for stability.
In the end I discovered my issue wasn't having enough vcore but having what appears to be too much of a load (?) from the cpu overclock and the ram overclock at the same time.
I had been running the xmp oc for the ram at 3200 which was putting 1.35v to the dram. I experienced extreme temps and shut downs during my cpu overclock tests after a certain point (4.6 and beyond seemed to be the point the issues started to appear)
I decided to reset my ram oc and try undervolting it. I finally settled at 2666 with 1.2012v even though the ram I am using is G.Skill 3200. I then attempted my cpu overclock again and was able to push it much higher. Currently completely prime29.4 stable at 4.9 adaptive 1.2-1.332v with a -2avx offset with both avx on and avx off prime tests.
I have my vrm temp monitoring turned off on the motherboard because I could see what appeared to be power throttling on on intel power gadget a few minutes after I had started the prime test. When I turned off my vrm temp protection, the issue disappeared. (I do also have all my power limits maxed out). I have tightened the heatsinks on the vrms and have a 120mm fan pointed directly at them.
I checked the vrm temps (bottom of heatsink) with an ir thermometer and they appear to run around 50-60 with my 2666 1.2v, but way up around 80-90 with the 3200 1.35v which seems odd for ram that is listed as 3200 capable on the chip.
I have memtested the ram at both speeds and it passes.
I was unsure about posting here in the motherboard forum (for the vrm questions) or in the memory forum (for the ram voltage questions)
Does this sound more like a vrm limit issue or like a ram is acting up issue?
