The higher limiting voltage improved cooling and performance by allowing better thermal management.

You also have the option to adjust the LLC instead of using offset voltage. Try it out to see if it improves temperature stability.
I've managed to operate them at 4.2 with 1.29v for mainly gaming and light tasks. When pushed hard by demanding work, stability drops significantly and performance becomes erratic. AMD suggests around 1.32v for consistent results, though it usually holds steady at 4.0. Around 4.1 you start seeing issues and it's like a tough win. I stick to 1.34v and revert to the last stable setting if anything goes wrong. If it shows instability, I won't run it.
It seems some silicon performance often comes with a cost. I believe the typical safe operating range for silicon was around 1.32 volts under high current conditions, and up to 1.47 volts for lighter loads. There were discussions about potential CPU issues and gradual degradation, but the system handled 256-bit workloads without major problems. Stability loss due to wear is real—just avoid pushing the processor beyond its limits unless you're into competitive overclocking or just love chasing performance numbers.
The best part is the absence of an LLC option in my BIOS. I'm puzzled about why the voltage controls are so restrictive compared to other Gigabyte models online. However, I do have an offset feature, though it doesn't perform as well as limiting peak voltage. My main worry is that PV limits might affect performance in demanding applications like Cinebench, while others may struggle with insufficient voltage. According to Jurrunio, adjusting the fan curve can help—keeping fans active at higher temperatures and maintaining stable temps. This likely explains why I don’t notice much variation between 40% and full speed for CPU temps (just a few degrees). My cooler handles 65W TDP without issues, but I can't adjust internal temps much, which is probably why the reported CPU temps are accurate. The solution seems to be running the fan at low speeds, resetting voltage to default, and ignoring temperature readings.
Both my wife's and my gaming systems operate at 4.2 volts across all cores at 1.2V. I've checked Blender, cinebench, and F@H for 24 hours—performance is significantly better and cooler than PBO. While I don’t have access to the best silicon options, I need to push up to 1.3V to run 4.4 all cores on my 3600. It’s not stable in Blender or similar tools, but it works smoothly with Kombuster CPU burner. I’ve been using it for a while now without any gaming issues, which is my primary goal.
Began to question the numbers. Blender tests with Chrome background showed performance differences. BMW benchmarks indicate 4.4Ghz at 1.237V runs cooler than stock specs. Is there a reason to increase voltage? Look for tests or benchmarks that confirm suitability for your setup.
I haven't managed to reach 4.4 on any of them. 4.2 was the best so far at 1.34v, but I never achieved consistent results—usually failing around test 3 in prime95. I don’t think anything is stable enough for me until it runs under prime95 for about an hour. It might be that it becomes more unstable there, or maybe just bad luck. My data comes from a very limited group of 3 Ryzen 3600s. If it works at lower voltages, then it’s better. I always stress-test everything in prime95 for an hour or so. That gives a clearer picture of its stability. Prime95 is still an extreme workload for most users.
