Initial Ryzen setup. Looking for assistance with OCng/Power settings.
Initial Ryzen setup. Looking for assistance with OCng/Power settings.
First Ryzen Build, 5950x, appears much more complicated than necessary when compared to Intel. It’s becoming increasingly frustrating. I have a stable Manual/All Core OC at 1.29V with a speed of 4.67 GHz. I get up to 72 degrees of performance for about 20-30 minutes. However, my single core z scores keep changing between 627 and 637. Others with lower core clock speeds seem to achieve higher single core performance. I thought it might be due to power limitations, but I can only change power limits, TDP, EDC, etc., with PBO enabled. I tried that and got a consistent 640 single core every time (still low, but progress). When I look deeper, people claim PBO/Masnual OC are exclusive. Can I skip using PBO power settings and Manual OC? There don’t seem to be any basic power options in the manual OC section of my motherboard (B550 Gaming Carbon), and it seems to function well. What am I missing?
Why are you trying to OC a 5xxx Ryzen? Enable PBO and keep it as cool as possible. You can also trying applying a negative voltage offset. Just keep an eye on decreasing boost frequency.
Calm down, Francis! No hating was implied at all. I'm not even sure how one could see any hating in it unless they are a fragile, easily offended person.
No, you cannot use PBO and a manual OC at the same time. Happy?
In my initial response I also mentioned some options such as turning on PBO and adjusting the CPU voltage slightly. The latest models of Ryzen perform well in achieving maximum stable core frequency even under stress. Sometimes they adjust the voltage too much, which can result in cooler temperatures and higher clock speeds.
Are you monitoring "effective" clocks to make sure you're not encountering clock stretching?

Thanks for the update. I was expecting something very similar. It seems to be a slight drop in frequency, around 4.65-4.7 with CPU Z fluctuating between 630 and 643. The clock accuracy looks good overall. Under full load, it's about 4.6997, and during single-core testing it's around 640 on CPUZ. When I open the Windows monitor, it drops to roughly 627. It's a bit lower than my usual 4.67, but I'm not sure what's causing this.
Can I help you understand this better?
The scores differ by only about 3%. That’s probably just a normal variation. It doesn’t seem like something significant to focus on. If you’re aiming for CPUz records, you’ll need to be significantly above 4.7GHz.
For everyday use, it’s important to ensure your voltage isn’t too low, as that can cause clock stretching. Try to keep voltages as high as possible to get better performance and save power. After that, just enjoy using the PC.
