Windows stops working when I exceed 4.5 ghz
Here are the details you provided, rewritten in a different format while keeping the same length and structure:
So initially, my hardware setup includes a CPU with an Intel core i7 6700k running at 4.0 GHz, a GPU of Nvidia GFX GTX 1070 Ti, 2x 8 GB RAM sticks, and a motherboard from Asrock Z170 Pro4s. The system has an SSD along with two additional HDDs for extra storage. I first overclocked the GPU using MSI Afterburner and tested its stability with the Superposition benchmark. Then I moved on to the CPU, observing that its idle temperature reached 40°C. I attempted to push it to 1.2 volts and 4.5 GHz in BIOS, enabling all cores. After launching Windows, I began stress testing the CPU, which quickly heated up to 80-81°C within minutes. Eventually, the system crashed with a stop code indicating a clock watchdog timeout. I adjusted the BIOS settings, setting multiplayer to 44.4 GHz and 4.4 GHz to see if it would work better. It did, but I still find it puzzling why it doesn’t go higher, even when I try 1.3 volts, though it reverts back to 1.2. The biggest frustration is that it remained stable at 4.5 GHz until Windows decided not to run it anymore.
If it crashes after a while, it likely wasn't stable from the start.
