It may not be pushing you to thermal shut down but I bet you anything the spike in cores (which you have shown and admit to) can and will cause instability I have a far greater cooling and pump thank you are and I am moving more water. However I am still very limited. The H100i is very close to my setup so I know pretty sure what the limits can be and what the cause is,
Watch the temps on core and and Your VRMS,
now to explain why it helped stability in a way,
That frequency is what drives how fast the VRMs push out power, The higher the frequency the fast the current to the chip it goes (these are not exact terms but you get the point) the reason why having a high frequency can cause instability is that with so much more current and power draws there is more jitter
Now to put it in practice. If you get freezing and lock up but your voltage is high enough, It could be that the power frequency is not enough for what the chip demands. In which case raising that amount will help a lot (this will raise you VRM temps ALOT)
The instability is if your proc or other components are getting enough power however are getting it to fast the jitter makes the power more dirty and just causes issues leading to further instability,
It is a fine line. To push at the voltages I do I have my CPU frequency to 470, I probably can drop it but I have active cooling that is keeping my VRMs ccol and I a m not dealing with instability from it.
is 350 high? or normal? Max I can set is 400, 350 out of 400 sounds alot to me but I have good airflow in case. What would you prefere me to set it for 24/7 use? I might try 300 instead of 350 later, also yeah I tried before high voltage on 4.6 with auto VRM fixed frequency and it would still freeze, so this setting did help me.
How do I watch my vrm temp? I dont think the motherboard has a VRM sensor but when I touch the case where the VRM is, its not warm at all, its actually very cold/medium warm on load.
Edit: I have a Elite 430 case and there is not much room between the motherboard and case so when the VRM gets hot I would feel the heat at the top of case, I got rear and two top fans all exhaust hot air from the case and vrm etc.Edited by Sold13xr - 1/24/14 at 10:53am
