: Voltage for overclocking
Hi Jimsterino98
Voltage efficiency plays a crucial role during overclocking. Keeping CPU voltage at auto settings often leads to suboptimal performance. As frequency increases, more voltage is needed to keep things stable. Additional adjustments like LLC calibration are necessary to avoid voltage drops during high demand, and voltage offsets help determine the processor’s operating voltage.
Wow, that sounds like a lot of voltage tampering—I won't overclock without some help, cx.
What are the details of your system? Motherboard, processor, GPU, PSU, cooling setup, etc. You can choose to leave it on AUTO, though this may restrict your overclocking options. This setting can affect performance and stability, so testing is important.
Usually "Auto" voltage leads to a higher than necessary voltage. This is true for both CPUs and GPUs. The motherboard or GPU will trigger an error on the safe side because they use a BIOS profile from the maker that covers most chips to keep things stable.
In practice, you usually start with Auto voltage. When instability appears, reduce the frequency slightly so Auto voltage becomes steady again. After that, gradually lower the manual voltage. Reducing voltage means less power and less heat, which gives more room for optimization because temperatures drop.

I can share my experience, but it might differ for you:
I own a Ryzen 1700 in an MSI B350m Mortar. I was able to overclock it to around 3.8G using Auto, with the VCore around 1.34 to 1.36 volts and LLC at 1. At 3.9G it would crash every time I ran stress tests with Prime95 small FFTs. I had to manually adjust the VCore to 1.3875V for stable performance at that speed.
This situation could have changed since those were pre-Gen2 Ryzen models, and the BIOS might have updated. Always verify the OC settings after updating the BIOS, as they may no longer match your previous configuration.
Consider trying auto voltage until it fails, then fine-tune the voltage afterward.
Or keep it at a few straps below where it hits the ground. However, it isn't always straightforward...the temperature must also stay properly regulated.
what are effective tools for stress testing? your cpu runs at 4 ghz with stable auto voltage and no issues.
