PBO and CO inquiries. First-time here.
It’s safe to enable PBO with everything on auto and set the curve optimizer to -30. This configuration won’t harm your CPU performance, and it shouldn’t trigger any warranty concerns if you ever need to return the unit.
We discover this through everyday operation. Adjustments become necessary if you encounter unexpected freezes or shutdowns. Lower the value to -25 and retry. This approach doesn’t change once the device is removed; settings remain hidden from others. In practice, it’s unlikely to be an issue. Most people perform this without considering such details, treating it as a minor concern.
A negative CO offset won't harm anything; it mainly reduces the voltage/frequency line, leading to lower voltage and maybe a slight overclock. The 9800X3D comes with solid default configurations, so noticeable gains are unlikely. Try adjustments one at a time for best results.
Here’s a clearer version of your message. I tried to simplify the points and keep it easy to understand.
You’re wondering whether to use PBO and CO, and you want to avoid any problems with your 9800X3D. I asked ChatGPT for advice and also checked with them again. Here’s what they said:
- **What you have:**
- AMD Ryzen 7 9800X3D
- Corsair iCUE H150i ELITE
- ASRock X670E Pro RS ATX AM5 board
- Corsair Dominator Platinum RGB
- Lian Li LANCOOL III case
- Inland Premium M.2 SSDs
- Dell Alienware monitor
- MSI VENTUS 3X graphics card
- SteelSeries headsets and mouse
- SteelSeries Arctis Nova Pro headset
- Lian Li 24-pin and 12hpvw ones
- **Should you use PBO and CO?**
Yes, they can help boost performance safely if you follow the right steps.
- **How to set them up:**
1. Turn on PBO in BIOS (press Del/F2 at boot).
2. Enable Curve Optimizer in AMD Overclocking settings.
3. Adjust PBO and CO values carefully to keep temps low and stability high.
- **What to watch out for:**
- Keep CPU temps under 90°C.
- Watch stability with stress tests.
- Make sure your cooling and power supply can handle the extra load.
- **Possible downsides:**
- Slightly higher power use and heat.
- Risk of instability if settings are pushed too far.
- Noise from fans might increase.
- **Warranty:**
AMD’s warranty should stay valid as long as you don’t exceed the CPU’s limits. PBO and CO are built-in features, so they shouldn’t void your warranty unless you go over TDP or voltage limits.
- **Tips for smooth operation:**
- Use a good cooling solution (your Corsair H150i should handle it).
- Monitor temps and stability regularly.
- Don’t push settings too high without testing first.
In short, PBO and CO can improve performance, but it’s important to stay within safe limits. If you follow the instructions carefully and keep an eye on your system, you should be fine. Let me know if you need more details or help with specific steps!
ChatGPT replied:
Just keep an eye on your temps and stability. If you’re unsure, start with conservative settings and adjust gradually. You’ve got this!
Don't stress. Just add PBO and CO, crank it up to 200Mhz, and enjoy gaming.
Its okay I'v been in your position where I was scared or worried that something would break. Its good to ask questions and we encourage it. I sometimes also forget that other people are new to this.. I have been doing this for over 2 decades. Back when I started overclocking and messing with systems there was very little information. We just had to try The problem now is, there is too much information and its difficult understanding and finding exactly what you need to know or want to know. The 9800X3D is out of the box a very fast chip. PBO and CO is barely even an overclock compared to 'real overclocking' And adding +200Mhz is nothing major. We have people running this chip at 5.7 and 5.8Ghz and they are pushing it quite abit. Higher clockspeeds will result in diminishing returns, its not linear. So a modest PBO and +200Mhz for a 5.425 - 5.5Ghz is okay So here it is. I plan on having my own 9800X3D for at least another 5 years. I am running +200Mhz, x10 Scalar, PBO and -30 Curve Optimizer and I not worried in the slightest that this will harm the CPU. If i planned on keeping this CPU for another 15 years I would still run this exact setting. Its such a minor tweak compared to proper overclocking that we do on Intel chips or AMD back in the day. PBO and - Curve Optimizer is actually a slight undervolt while increasing performance, so we are actually sliightly reducing voltage instead of increasing it, hence why you see lower temperatures. We are not pumping more voltage and power through it, we are reducing it! So this is actually one of the safest overclocks you can do. Free performance baby! Thats why some AM5 CPU's are not stable at -30 CO as this lower voltage a bit too much but they are stable at -20 CO. So set what you feel comfortable with, stop worrying and use the CPU for what its made for. Play them video games!
