Hi dacster
Thank you for listing your pc specs.
The first thing I will have you do is install these three programs:
1) ROG Realbench for stability testing.
http://rog.asus.com/rog-pro/realbench-v2-leaderboard/2) ROG CPU-Z for cpu frequency and voltage monitoring. Near the top of this page click setup in the ROG version, then click download now, then click run.
http://www.cpuid.com/softwares/cpu-z.html#version-history3) Real Temp 3.70 for cpu temp monitoring.
https://www.techpowerup.com/downloads/2089/real-temp-3-70Once you get these installed open up all three programs, let's do a test at default settings and see where temps are and how much voltage the cpu is drawing. In Realbench click stress test beside benchmark, select how many GB of ram you have and select duration 15 minutes.
Click start and monitor real temp for cpu temps and cpu-z for the voltage which is the vcore, if the temp goes over 90c stop the test immediately.
Please tell me what the temps are and what the vcore is showing during the test.
