Hey everyone! I've got a 9800X3D CPU paired with a Gigabyte B850M Gaming X motherboard and an Arctic Liquid Freezer III Pro AIO cooler. I've undervolted my CPU, aiming for around 1.2V due to some concerns I've heard, and I'm trying to ensure it lasts a long time. My BIOS version is F4, released on 23/05/2025. When stress testing, my clock speeds never exceeded 5425MHz initially, but after gaming for a while, I noticed my clock jumped up to 5627MHz. Is that expected? Should I be seeing higher clocks based on my settings? What are safe voltage levels for the 9800X3D to maintain longevity? I'm not too experienced with overclocking, so I'd appreciate any insights! I gathered these results after gaming for about 4 hours and then checked with HWMonitor. I'm concerned about the temperatures too, as the max I recorded was 79.5°C for the package. Thanks for your help!

You should also check PBO (Precision Boost Overdrive) for stability using AIDA64. There’s a chance your settings might be unstable if you're seeing those varying clock speeds. It’s definitely worth running some tests!
First off, HWMonitor tends to give weird readings on Ryzen CPUs, so I suggest checking out HWInfo instead. If you don't have Boost Override enabled, your clock speed should max out at around 5250MHz out of the box. But those voltages and temps look fine to me! You’re in a good spot!
I am using Boost Override, just the base +200 and not the multipliers.
Honestly, everything looks good! While the temps are a bit on the higher side, you’re pushing those clock speeds, so that’s to be expected. Remember, clock speeds can fluctuate, and some cores might peak higher for brief periods. You might want to keep your max clock around +100 to manage temperatures better.
It was all cores on the same clock, and I got confused when I saw the numbers jump; I'll keep that in mind.
Alright, I’ll check that out tomorrow!
