Overclocking the Intel Core i5 4690k

Voltage readings are long gone from when this was performed (writing this over 9 years later), as were temperature and power readings at each frequency interval. The results from increasing the all-core boost from the stock 3.9 GHz to 4.6 GHz are shown in the performance matrix below, with extra results at 4.7GHz pictured separately.

Extra Results

The following results are at 4.7 GHz. I didn’t get too many readings since I was well over the generally accepted safe voltage for Devils Canyon CPUs of ~1.35v, rather to sustain 4.7GHz for long enough to get the wPrime and SuperPi test results, I had to pump around 1.47v, and had a dedicated cooling fan for the VRM.
