Short summary: I used easytune to implement a very small OC on my CPU and RAM. Then the LED bars on the DIMMs started going out. Then the SPD info shown in CPU-Z and HWinfo64 became corrupted. Then the system started failing to shut down properly. The more the hardware information gets queried, the more corrupt it gets. I'm now out of my depth and seeking assistance.
After moving the DIMMs to different slots I uninstalled the easytune application and the easytune engine, and then forced a few reboots. Still the same problems. LED bars are all lit up on reboot. But immediately upon opening any program that collects the RAM's hardware info, the info becomes corrupted and the programs lose their ability to recognize any of the DIMMs, one at a time, in a seemingly random order.
First of, I have a 4690K on a Gigabyte GA-Z97-HD3. I ran Easytune and it gave me a 4.3GHz... with 1.33Vcore. Stress test OK with max temp going to 81C. After reading a lot I see the voltage is pretty high, even with the temps being OK. Is there anything I can do to lower the voltage, or easytune really tested it to be optimal?
