I accidentally messed up my CPU help!
hello, initially i had no experience with oc and never tried it before. i faced an issue with the voltage of my cpu core while idle, which should be around 1.300v to 1.350v. people suggested updating the bios, so i did that for the first time. after the update, all my bios settings changed slightly, and the temperature dropped a bit. however, since then, there have been several changes—first the ryan zen master peak voltage reached 1.5 while running an old game, so i switched to manual mode and set the peak voltage in profil to 1.09375. this fixed the voltage problem. now, in task manager, the base speed is 4.00 ghz, which is lower than the previous max of 4.10 ghz.
i have:
amd 5 3600x
asus prime b450m-k
gtx 1070 aero
crosair cv 650w bronze
16 ram
1 tera ssd
sorry for my english and typos, thank you for your time.
Ryzen isn't the same as Intel. Intel CPUs are static, you define the maximum boost and voltage, and the CPU follows those settings no matter the temperature or power demands. If it can't meet them, it will crash.
Ryzen operates differently, even with PBO. They are self-regulating dynamic CPUs that stay within their set limits. PBO mainly increases the working capacity. With a 65W TDP CPU, PBO can raise the limit if cooling is good and voltages are low enough—like 90W in some cases.
Using PBO usually doesn't make much difference because the CPU rarely needs that extra limit.
Consider removing the Ryzen Master, ensuring the BIOS is up to date if necessary, applying optimizations, and disabling PBO before saving and closing. Restart Windows, then download and install the newest AMD chipset driver from the official site, restart and reboot, adjust the power plan to AMD Ryzen Balanced Power Plan.
Updating BIOS without updating chipset drivers might cause various unusual actions. If you're using Windows 10 64 bits, you can download the latest drivers from the provided link:
https://www.amd.com/en/support/chipsets/...t-am4/b450
(Ensure you select the correct ones if needed).
The suggested approach is to remove all chipset drivers via the control panel (if installed manually), restart the PC, enter BIOS, and apply default or optimized settings using the F10 key to save and exit. Then install the new drivers and restart again.
If everything functions properly, you can return to BIOS and enable XMP/DOCP. As mentioned by Koekieezz, it's crucial to keep PBO disabled. Good luck!
Yeah, PBO still has some issues with voltage. I tested it on the b550m gaming rig with an R5 running at 3600, updated the BIOS to the latest AGESA, loaded all defaults and optimizations, and turned on PBO just for testing. It started up fine to Win 11 and got the newest chipset driver installed. I used the Ryzen balanced power plan. When under load (just using AIDA64 stress FPU), the voltage fluctuated from 1.3 to 1.4 quite a bit. But when I disabled PBO, everything ran smoothly—no spikes detected, max voltage capped at 1.35V, and it felt cooler by about five degrees.
Without PBO you are losing some performance but if that meets your requirements and causes issues, it's better to omit it. The main factors are proper cooling and voltage regulation. You might consider checking out this resource: https://www.guru3d.com/articles-pages/cl...ide,1.html, which helps in achieving the best performance at ideal voltages and temperatures. It's more than just an overclocking tool.
Ryzen isn't the same as Intel. Intel CPUs are static, you define the maximum boost and voltage, and the CPU follows those limits no matter what. If it can't, it will freeze.
Ryzen operates differently, even with PBO. They're dynamic processors that stay within their set boundaries. PBO mainly helps push those limits a bit further—only if cooling is good and voltages are low enough. For most users, this has little impact because Ryzen rarely needs such an increase.
Regarding voltages, proceed with caution. The CPU isn't at risk, but your expectations might not match what Intel does. Older games will likely run very slowly, using just one or two threads. Ryzen can handle up to 1.5V for those threads and lower power draw, allowing higher boosts like 90W if cooling and voltage are right.
In practice, PBO mainly affects the most demanding scenarios, not everyday use.
As for performance, Ryzen won't overheat or cause damage unless you misconfigure it. It's better to trust the design rather than rely on manual tweaks that treat it like Intel.
I don’t really enjoy PBO or Ryzen Master. I prefer to trust the engineers who built them—they know exactly what they’re doing, and CTR2.1 is just a fine adjustment tailored for each specific chip, not a one-size-fits-all setting.
Just let the Ryzen run as intended, and you should avoid any problems.
PBO belongs to the Ryzen algorithm, and the Ryzen master is also credited to "engineering geniuses who designed the Ryzen".
CTR comes from 1usmus, a recognized Ryzen expert who uncovered data that AMD hadn't shared publicly. He's also known for memory optimizations.
PB is included in the Ryzen algorithm, while PBO stands out as an additional feature beyond standard operations. It's essentially a minor backdoor bios configuration that enables AIB partners to enhance CPU performance. Fundamentally, it's similar to Intel Z boards which can increase the multiplier beyond the default, but this capability is exclusive to AIB boards and not available on any Intel-manufactured motherboards.
Ryzen Master wasn't developed by the original Ryzens team; it's a utility created by software engineers, likely the same group responsible for coding the Radeon drivers. These developers have consistently produced successful and bug-free software.
Yuri Bubliy (1usmus) is highly skilled and very focused on improving Ryzens performance. He has largely rejected RM and PBO in favor of CTR and the new Project Hydra for Zen3/Zen3+. The BIOS setup required to run those programs actually advises disabling them, suggesting they are not essential. CTR merely fine-tunes each chip to perform optimally within its limits. While users can opt for PBO to push boundaries, it simply expands existing constraints rather than altering core functionality. Ryzen Master operates similarly, but through manual adjustments. Unless you consider yourself a skilled Intel OC, merely increasing limits only offers marginal gains, similar to just boosting an Intel multiplier.
On my 3700x with PBO and RM, I achieved over 4700 with all cores at 4.4GHz and 83°C. Using CTR2.1 brought me to 5010 across all cores at 4.2GHz and 69°C, with a single-thread performance boost of 63 points. I find it hard to dispute those results. Anything I run consistently runs cooler and delivers 5-10 frames per second faster. This includes tasks like using the Drm calculator on both sides.
