    I have to do per core on this. I have a 5900x with the B2 stepping and I can do 30 on 4/6 cores on CCD1, 28 on the other two, and on CCD0, it's between 15-19 for those cores.
    I MAYBE understand how people can go and slap 25-30 on all core on their CPUs. It has to do with core parking partially, and the boost you add to your clock speeds. With core parking on, a lot of cores shut off, and the couple that stay on will hit the max boost you set when you're at idle. If that isn't stable, then you crash while idling.
    But with core parking off, no cores shut down. And no cores will ever hit the max boost frequencies that you select in the BIOS.

    • @MacCoyzkie
      @MacCoyzkie  6 дней назад

      Sounds like you're really digging into the details of core behavior and boosting. You're right-core parking can definitely affect how boost frequencies behave, and turning it off can lead to more consistent performance across all cores. It’s interesting how stability can vary depending on how these settings are managed!

    • @MacCoyzkie
      @MacCoyzkie  6 месяцев назад +7

      When PBO2 is set to "Auto," the motherboard and CPU handle the boosting parameters automatically based on a variety of factors, including:
      1. cooling Solution: If you have a robust cooling solution, the CPU will boost higher since the thermal headroom is greater.
      2. Motherboard VRM Quality: High-quality VRMs can supply more power, enabling higher boosts.
      3. Workload: The type of workload (single-threaded vs. multi-threaded) will affect how the CPU boosts.
      when PBO2 is set to disable, it forces the cpu to use the stocks settings.
      The reason why i set mine to disable and set the curve optimizer like so is because my build doesn't seem to be doing a good job in AUTO mode. If i play AAA games and render videos my pc keeps shutting down.
      if your build is doing fine with the current settings then I guess you don't need to do what i've done in this video

      @MacCoyzkie  29 дней назад

      @@bassboosted4life342 You're right that many people suggest setting PBO2 to the motherboard's limit as a precautionary measure, especially to avoid potential power delivery issues. The motherboard's VRMs play a significant role in supplying stable power to the CPU, and if they're not up to the task, it could lead to instability or even hardware damage in extreme cases.
      However, if your motherboard has high-quality VRMs and proper cooling, it might be capable of handling higher boost settings without issue. It really comes down to the specific brand & mobo model name you're using.

      yes but be careful. First go to bios, look if the you have the option called "core voltage" then "offset" and usually that is in auto just make it negative increments like -5 millivolts at a time, save and exit bios.
      stress test it until it becomes stable, if you see no display just clear cmos and redo things again until you find your pc's sweet spot undervolted settings

      @@ChikaHakozaki You're correct that some users with b450 mobos, like the MSI b450 Tomahawk, have reported using pbo2 after a bios update. While it's not officially guaranteed across all b450 boards, many have added support for it with newer BIOS versions, particularly with Ryzen 3000 and later cpus. The reason for limitations is that not all b450 boards have the same power delivery or features required to fully utilize pbo2, which is why support might be inconsistent. If someone is looking for more reliable and future-proof support, recommending a b550 mobo is a great choice, as they natively support pbo2 and newer Ryzen features without needing as much dependence on bios updates

      follow the same in this video but in the curve optimizer start value start with 30, stress test it and if it shuts down means it's not stable, go back to bios again and change it to 29 next, stress test again and if it didn't work try 28 and stress test again and so on. increments value should be 1. sometimes you will get no display so simply clear cmos to reset everything to default

    Hey man so first test I set my core offset to -20. It crashed. So I tried -15. Unstable but I notice max temps didn’t drop, but my temps under load are lower. So like when I’m gaming it is lower???? That’s so odd. I’m on a 7600x. I settled on doing -50v cpu vcore. And -10 offset curve optimizer. I get crazy low temps now but still same max temp???? Also would this pbo thing hurt my cpu long term? Thanks.

    • @MacCoyzkie
      @MacCoyzkie  5 месяцев назад

      Setting a core offset to -20 caused your system to crash because the voltage was likely too low for stable operation. At -15, the system was still unstable, which is common if the voltage is insufficient for the CPU under certain loads. Finding stability at -10 is good, as it seems to be a balanced setting for your specific CPU.
      It's normal to see lower temperatures under load with a negative offset since the CPU is operating at a lower voltage, which generates less heat. However, the maximum temperature might not change significantly because PBO2 dynamically adjusts the CPU's power and thermal headroom to achieve the highest possible performance. When the CPU is under maximum load, it will still push to the thermal limit set by your BIOS, which explains why the max temps are the same.
      Using a -50mV CPU vcore offset along with a -10 curve optimizer offset is giving you lower temperatures while maintaining stability, which is great. This setup reduces power consumption and heat output, hence the lower temperatures under load.
      your current settings seem well-balanced for both performance and thermal management. As long as your system remains stable and temperatures are within safe limits, you shouldn't have to worry about long-term damage from PBO2 adjustments. Just keep monitoring and adjusting as needed!

    Mine crashes on 30 all the way down to 15….

      testing increments step should be 1, start from 30, 29, 28. if it still crashes then i guess the pbo2 might not be good for your pc. you can clear cmos to reset everything to default

    Does undervolting with pbo voids warranty. (I am a total newbie)

      it does but you don't need to tell the store that you overclocked it in any way in case you'll be using warranty

    I set that to negative 30 all cores
    I get black screen once in a while but it has a performance boost
    I am ok with black screen, it only freezes for 5 seconds then its back again

    • @MacCoyzkie

      try -1 increment and stress test it until you fine a stable number. that one going black screen is fine for the first time but if its going to become constant that won't be good for your system
