Overclocking my i5 4670k
Overclocking my i5 4670k
I'm experiencing an issue while overclocking my 4670k, even when running at 4.1 ghz with 1.19v. During stress tests with linx, the temperature stays around 80-85°C with a maximum of 88°C, and it dropped after about three hours of testing. When I restart, things seem to stabilize. For Prime95 26.6 blend test, the temperature is about 60°C with a max of 65°C. Which one should I use? My PC specs are as follows: CPU i5 4670k, cooler be quiet dark rock pro 3, motherboard gb-series ga-z97x gaming3, ram kingston hyperx fury (3x 4gb 1866 + 1x 1600), case nzxt h440, bios settings with clock ratio 4.1ghz, uncore 3.3ghz, vcore 1.19v, cstates enabled, xmp off, turbo boost off, and the CPU fan running at full speed. My target is 4.4ghz with less than 80°C.
radennstaff, Prime95 v26.6 Blend works well for memory testing, while Small FFTs are optimal for CPU thermal analysis. For system stability checks, Asus RealBench is recommended due to its near 120% workload capacity. Both Prime95 v26.6 and RealBench match about 100% workload usage. • Asus RealBench - http://rog.asus.com/rog-pro/realbench-v2-leaderboard/ Read this Sticky: Intel Temperature Guide - Follow the instructions in Section 11 - Thermal Test Basics: "...
