I’m concerned after reviewing many forms on the site and seeing my PC’s display acting oddly. I increased my i5-6600k to 4.5 MHz and set the CPU voltage to 1.3V in Gigabyte BIOS, but Prime95 and the Gigabyte monitor show stable performance at 1.2V and 4.5 MHz. Could I have missed disabling an auto setting? Also, my Prime95 run lasted 3 hours and all results were stable with a temperature of 66°C.

Well if it holds steady at 1.2v that's a positive sign. Check HWinfo64 or HWmonitor to find out what the CPU VCORE reads, as gigabyte isn't known for offering top monitoring tools. If it also shows 1.2v, enable LLC (load line calibration) in the BIOS at one of the lower settings and avoid overclocking. This will help reduce VDROOP, preventing the CPU from falling below your specified VCORE voltage during load.

If it holds stable at 1.2v that's favorable. Consider using HWinfo64 or HWmonitor to check the CPU VCORE value; gigabyte isn't known for top monitoring tools. If it also shows 1.2v, enable LLC in BIOS at a lower setting and avoid overclocking. This helps prevent VDROOP, which can cause the CPU to fall below your desired voltage under load. I also used cpu-z to track temperature and voltage. For LLC settings, my BIOS auto-adjusts. Are you certain it's accurate? Also, is it normal for an i5-6600k to run at 4.5MHz with just 1.2v?
