I lock my ratio at 42 and set core voltage at 1.3, which gives significantly cooler temperatures compared to auto mode. During stress tests, core clocks drop to 4Ghz in auto but stay steady at 4.2Ghz when manually locked. Many experts suggest Ryzen overclocks better than you expect for peak performance, but the high voltage in auto mode likely causes excessive heat and slower cores under load. You might want to stick with manual overclocking to avoid these issues.
It’s common to hear that Ryzen voltage settings are often misused, with values set too high rather than optimized for real performance. People are usually warned against overclocking Ryzen not because it’s impossible, but since it rarely delivers meaningful benefits.
It's hard to grasp why such low voltage settings might still benefit performance over time. While it reduces power consumption, it also cuts clock speeds, which can limit efficiency. The chip can still reach high speeds like 4.3+ GHz when idle, but only under minimal workloads. You might need to verify if the system is handling voltages and temperatures well enough for regular use.
Most configurations I set automatically result in excessive factory voltage. I adjust my Intel systems to boost performance and reduce output when pushing overclock or undervolting. The default values for 4800 and 5000 MHz are much higher than what I can achieve with custom settings, which let me run cooler and handle more voltage. My 2700x is nearly ten years old now. I’ve stuck to stock (PBO) throughout because there’s little room for meaningful improvement. The lower temperatures I achieved on my 9900k with tailored settings let me run at full frequency with headroom, whereas the board’s default limits performance regardless of voltage or temperature. Overall, it doesn’t really pay off to tweak further unless you’re okay with noise or silence.
My 2700x passed 4.3ghz on IBT at roughly 1.475v + high LLC manually overclocked. Beating the PBO boosts requires no less then just having better temps, but beyond that frequency will be a no go. My ROG board with Performance enhancer lvl 3 and 4 where written. By the Stilt. #4 PE is an all core 4.3ghz auto clock and the max the board has to offer. Just as stable as manually overclocking and every bit as much vcore. I've chalked the 2700x to have a max vcore daily of no more than 1.410v. I do know factually that when you get close to 1.6v or at 1.6v, ambient and even a chilled water loop is not enough. This voltage will instantly wipe the cpu right out. No I'm not directly admitting my Ryzen 3 1200 doesn't like me any more, but it still works, just not at high overclocks (exceeding 4ghz) and seems to require chilling now. The max Ive gotten 1st and 2nd gen to about 4.5ghz and that's about all you can squeeze out even chilled water loop. However, the best discovery was how much leakage is reduced when running colder temps. You really can get away with a really low vcore with temps between 0 and 20c. Roughly 1.2v for 4ghz. No need for liquid here. The stock prism cooler handles 140w and the 2700x isnt really going past this wattage. Nothing short of Dice or LN2 will make these chips any faster. Just set it up and turn on PBO and enjoy.
