Highest longterm voltage?
Highest longterm voltage?
I received an I7 6700k overclocked to 4.6GHz @ 1.32xV, but I won’t push it to 4.7GHz. I’m unsure what the optimal voltage should be. My cooler is a Corsair H100i v2 and I’m using a MSI Tomahawk AC (the best board I’ve tried for 100£). Which stabilization testing software should I use? Currently, I’m only using Cinabench and Intel testburner, but I’m seeing very different temperatures. I went from 873CB to 998 without a GPU in Cinabench. Also, what do you think about my English? My teacher says I’m not learning much because I’m not writing things down, but I won’t let them down. If you could help, please say your English is great—it would really boost my confidence! Thanks! <3
It's generally safe as long as you grasp that even "safe" overclocking involves some risks. If it remains stable at a lower voltage than 1.42, keep it as low as you can. Based on what I've seen, if 4.6 works at 1.32, 4.7 should likely work between 1.37 and 1.39. Good luck!
Asus suggests 1.40V is the optimal setting for air cooling, while 1.42V is ideal for water cooling. I respect their guidance fully. Good samples can reach 4.7GHz with a stable 1.40 Vcore. For water cooling, especially with AVX2 routines under stress tests, they recommend up to 1.42V with triple-rad water-cooling, or lower if temperatures are high. Those not focusing on stress testing can aim for up to 1.45V for peak performance.
I don't have specific recommendations, but you might consider checking common stress test programs used in your field.
Many people have their preferred brands, but I prefer Asus RealBench.
However, I'm experiencing significantly varying temperatures in Cinabench and Intertestburn even when operating at 100% load.
It's typical for various code types to affect power usage differently. I prefer RealBench since it identifies instability that other tests miss, and it simultaneously challenges CPU, GPU, and RAM. I don't suggest running Intel Burn Test – the last time it was used, my CPU and motherboard suffered damage.
