Undervolting noob. (assistance with R5 5600)
Hey everyone, I checked a tutorial on Reddit about undervolting. I visited MSI Bios with the newest update, set PBO to Advanced, turned off the PBO limiter, and adjusted the CO to -30. When I ran CinebenchR23, it came out at 4.35GHz with 1.063V and 72°C. Are these results satisfactory? I also tried -25, -20, and -15, but those gave lower clock speeds at the same temperatures. Thanks!
Hey there,
Usually bios works best for OC/undervolting. But if you're new to it, it can cause issues because too many changes are made. Have you tried CTR 2.1 or Project Hydra? Give them a try and check the outcomes. These can serve as starting points for your undervolt settings.
Instead of lowering voltage directly to the CPU, consider using an offset. You might also adjust LLC at the next level above the default. On some motherboards this is set to 1-4, sometimes Low, Medium, High, etc.
Based on what you've seen, 4.35ghz looks fine. Still, I usually set 1.25 volts for 4.65ghz on my 5600x. My CPU is quite responsive, so at 1.37 volts I can push it to 4.65ghz across all cores, and boost two cores up to 4.85ghz.
Check your setup carefully. Once everything is reset, use a CTR of 2.1 as the starting point. To apply an offset or LLC, adjust the relevant parameters accordingly.
So, if you plan to use CTR, then perform it in this way:

- Pay attention to the steps carefully for optimal outcomes. If you apply CTR, keep LLC aside.
For the vcore offset, there is an option beneath the voltage. It could show a '+' or '-'. Pick the minus choice.
:ets mention that if your vcore is set to auto or a precise value, adjust the offset to lower the voltage.
Therefore, if your vcore is at 1.35, adding an offset of 0.05v will bring it down to 1.3v. Understand the point?
