discussion PBO setting

[fightingfi]

So im using this motherboard, https://www.gigabyte.com/Motherboard/B850-EAGLE-WIFI6E-rev-1x

I see my PBO is disabled. It gives me like 10 different options and Level's of PBO settings. What one do i use if any? amd 9800x3d cpu

PBO Manual. Set your PPT/TDC/EDC, your boost override, your curve, save and exit.

Ryzen master can help you determine some realistic curves and such.

One odd word of warning compared to previous types of overclocking, curve offsets crash on transition from High -> Low load where classic overclocking used to mainly crash on the transition from Low -> High.

My vote is for none. Increasing power limits mostly just increases power consumption and heat. I'd only adjust these if you are often doing a full multi-core load.

As for PBO2 / curve optimizer. Leave it stock unless you are ok with spending FOREVER trying to figure out what core is causing your crash. After 2 years I gave up and went back to stock.

Looks like they finally added 9000-series support in July eh, I honestly thought the software was dead. It was a real pain to get it removed too as I just used my same OS install from my 5000-series chip.

I think most boards have "AI Overclocking" now that you can try. It attempts to optimize all the values for you based on how good your cooling is as it monitors the CPU temperature.

I also vote none. Immerse yourself into tuning, get familiar with the software that people use to test with.

I will tell you this. The curve is not meant for undervolting. The curve meant to be used in conjunction with PPT/TDC/EDC and boost override.

Ryzen loves power, do not be shy with it. Also, do not manipulate vcore, or vcore offsets unless you intend to run a static overclock.
