My friend and i built a subzero cooling system out of an old AC unit (inspired by Linus's "Chilling Threadripper" video. The cooling unit is functioning beautifully (subzero idle temps), so we are attempting to overclock it. We are using an FX 8350 and a Gigabyte 990fx chipset motherboard. We were stable at 4.8ghz with 1.4725V. We set the CPU Frequency to 5ghz and began gradually increasing voltage until we were stable on Aida64 for 60 minutes at 5ghz 1.525V, but cinebench crashes instantly upon clicking run. We gradually increased the voltage to 1.565 with no change in the cinebench crashes. Both me and my friend are inexperienced overclockers and have little insight into the meanings of many settings in the bios, we would appreciate any pointers or general tips on the subject of overclocking. Below are pictures of my bios settings, the desktop picture is of when we were running aida64 and it was stable, the system only crashes on cinebench.
