Go for a manual overclock. If you are not going to run BCLK at 100 then it is wise to get the optimal skew voltage and settings as BCLK overclocking isn't very efficient and kind of dangerous.. For now you should manually set BCLK to 100 and then set CPU voltage to offset auto (may have to change a vrm setting from extreme to standard, optimized or manual setting first otherwise it will be greyed out). Later you can manually fine tune the voltage but I find auto is quite accurate for me and was super close to my manual setting. In digi+ menu (not sure if it has it's own menu on non ROG boards), change t.probe to extreme, LLC to 0%, vrm frequency anywhere between 300 and 350, over 350 is overkill for you. This will help stability while lowering voltage and heat. Asus links vccsa/io voltages together so set this to 1.05v and CPU PLL to 1.7 (can continue to lower without hurting stability and thus reducing heat). Mines stable at 1.55. Also, if you don't intend to use integrated gpu, disable it and then set it's voltage to offset -, and put it to the maximum value to reduce power used. Also, disable C3 and C6 states (core parking, causes instability coming out of idle for minimum power savings), and enable C1E and turbo. Oh and disable cpu speed spectrum as clock modulation just causes further instability. Hopefully, you will now be able to go from 4.2 auto overclock to 4.5ghz now and have same temps or lower.
