With my original Windows 10 install, I overclocked my 1950X to 4GHz & 1.25V. The actual frequency says 3.9GHz This was stable with video encoding and I could also run other applications. After I reinstalled windows because I changed M.2 drives and changed the cooler from the Enermax AIO to the Noctua NH U14S TR4, my computer would occasionally freeze up after encoding for a little while (cursor was frozen, computer was unresponsive and I had to force shut down by holding power button down.) I tried to increase volts to 1.262V and still freezes up. I assume the freezing up is instability due to not enough volts? 1.275 volts seems stable but is running a little hot even with the Silver Arrow TR4 that I just installed. (Thanks Kyle for a great tutorial on applying the TIM). Again, the freezing up would not happen 100% of the time but would do this somewhat frequently. What would cause the freezing up? Again, it didn't used to do this with the original install. I have the Asrock X399 Taichi and 4x 8GB Corsair RGB RAM overclocked to 3200 XMP Profile 2.0. Looking forward to insight and a solution. Thanks in advance.
