Temperatures must reach approximately 100c. At that point the processor will either slow down or shut off to safeguard itself. The low voltage used during the attempt to increase the multiplier is usually the main issue. Adaptive will manage the voltage within a range that varies based on the multiplier. There are additional fine-tuning controls that vary with the specific BIOS. For Haswell, the maximum voltage should be around 1.3v. However, Skylake and Kaby Lake can handle up to 1.4v. I settled for 4.2Ghz and lowered the voltage to 1.19V. The cache/ring operates at 3.8Ghz with 1.165V. These values might drop slightly at 4.2Ghz, which I plan to verify later. To date, I've maintained stability across various tests: IBT (10 passes), IXTU (15min), RealBench, Metro benchmark (game), and CS:GO gameplay. I don’t feel the need to push the system to extreme temperatures with other programs—I think Aida64 could handle some testing for a few hours without exceeding 63-64c. I aim to try running it at 4.3/4.4Ghz once more, to assess stability and adjust settings further. Still, I’m puzzled—this motherboard seems inconsistent. Even when I fixed the voltages to fixed levels (including an offset of 0.001V), the CPU would still jump to 1.216-1.224V during stress tests and benchmarks. All settings are set to "Override" where possible, yet I can’t pinpoint why stability drops at certain voltages. Thank you for your responses and any guidance you can offer. If you have further tips or advice, please share them!
