With PBO i cant get a good score at Cinebench for example, something about 4800/4900 and i can see at Ryzen Master that the cores goes max at 4.250 full load running the test
I tried manual OC for yesterday all day long and got a sweet spot at 4.4 1.337 vcore LLC Turbo and VSoc 1.1
With this config i can get 5200/5300 at Cinebench and almost the same temps with PBO
Now i have 2 questions
Why my PBO is so low? And can i stay with this manual settings as it seems better at performance? Even at single core it`s doing better, this vcore and all other configs are safe for 24/7 usage?
Tks again friends
What Agesa version are your Bios based on? I saw PBO's best results with Agesa 22.214.171.124 based Bios on my Aorus Master, but it is at stock performance expenses, so I think Gigabyte tuned the Bios for lower stock performance, and you regain that performance with PBO, showing it do something now...
Anyway, PB2 and PBO relies a lot on temperatures. What are your temp after a couple CB r20 runs? Testing my system, I get PBO do something when temps are below 70ºC. Past that threshold, sustained clocks are the same as stock. I run PBO + OC, 5x scalar and 100Mhz offset, and a negative 0.1v vCore offset to low temps. PBO on Auto, or any form of PBO with stock voltages, does nothing for me.
About core voltage, there is no official statement which is the max safe voltage for these 7nm processors. I try to not exceed the voltages I see when running my cpu at stock, all auto settings. For instance, I tune vCore and VRM LLC to not exceed 1.35v at all core workloads, and at the same time to stay as low as possible for idle and low load or single threaded tasks. The resulting clocks at this voltage will depend heavily on the silicon lottery, and your cooling solution. My aim is to not exceed 85ºC at full load when all core OC.
