During the tests, the CPU speed was set at 3.3GHz and Turbo was disabled in UEFI. Testing with the same stock timings was possible until 2133MHz was reached. To make the system stable at this frequency, it was needed to relax the timings and the voltage was set at 1.65V; the next step was to tighten the timings in small steps and for any modification I have ran HCI Memtest (Windows utility) with 4 instances for about a half an hour, to determine if the system was stable or not. When the correct timings were found, I have started to decrease the voltage until the memory was giving errors again and raised it with one step in UEFI, to obtain the best timings at this frequency, at the smallest voltage possible.
