Note: Testing 1.23V crashed Windows 10 (bluescreen) during the RealBench encoding benchmark test. I have the Intel i7-6700K on the ASUS Z170i Pro Gaming motherboard and air-cooled using the nice Thermalright Silver Arrow ITX. Just one pass each boot trying to gauge the relative performance trending between them. Here's a recap of my RealBench and CineBench scores for 4.5Ghz overclocks between 1.30V down to 1.24V so far. Maybe that has to do with the ASUS Digi+ VRM power control being automatically on at 4.5Ghz and below and turning itself off at 4.6Ghz and above. With a 4.6Ghz OC it crashed when trying less than 1.32V for example. It didn't crash during a test until at 1.23V. I'm surprised 4.5Ghz is being so accommodating for me. The ambient room temperature is 73 fahrenheit. I know the temps keep trending down a degree or so with lower voltages but score results seem to be stagnating somewhat. But I'm looking for a good candidate from the results below to do more in-depth stress testing with to verify 24/7 use stability. How do you evaluate overclock benchmark scores to choose what to go with? I like 4.5ghz 1.28V because the temps are in a solid good range compared to anything above it. I measured temperature changes with CPUID HWMonitor. I re-tested my 6700K overclock settings for a target of 4.5Ghz at minimum stable voltage with low CPU thermals and best benchmark performance. Cinebench R20 (Multi-Core) Cinebench R15. 3DMark Ice Storm GPU 3DMark Cloud Gate GPU 3DMark Fire Strike Score 3DMark Fire Strike Graphics 3DMark 11 Performance GPU 3DMark Vantage Performance SPECviewperf 12. So I'm not sure what to make of it, compared to keeping things set to stable 4.4Ghz at 1.28V. Intel Core i7-6700K CPU Review: Skylake, L2 1.0 MB, 元 8.00 MB, base frequency is 4.00 GHz. Just getting a feel for what might be promising to use. Admittedly I didn't do any long duration testing yet. I think the score results will fluctuate with marginally higher or lower results running at the same settings. Today I wondered if my 6700K could do 4.5Ghz at "less than 1.3V" so here are two example stress test runs of Asus RealBench at 1.28V and 1.29V, especially being air cooled with my Thermalright Silver Arrow ITX cooler and Asus Z170i Pro Gaming motherboard. Skylake seems to be a very forgiving processor.
