Auto is disabled. Enabled is default PBO which sets the PPT, EDC, and TDC to default limits depending on CPU's TDP rating. PPT is the wattage limit. EDC is the amperage limit. TDC is the amperage limit when temperatures are too high. For 65W processors like your 3700X, PBO enabled would mean PPT=128 for example. I forget what the EDC and TDC default values …

Apr 30, 2021 · PBO is not an on/off setting. It unlocks three settings related to power consumption - PPT, TDC, and EDC. That's power consumption, sustained current, and short-term current. The defaults for the 5900X are 142W, 95A, and 140A, respectively. If you reduce those values after turning on PBO, you will reduce your performance.

Jan 11, 2024 · PBO stands for Precision Boost Overdrive. It's basically the CPU looking at available power and thermal overhead and deciding that it can use some additional voltage to override the default maximum clockspeed. It is completely safe. Needs to be enabled in the BIOS. And while you're there, make sure that XMP is enabled, as a LOT of folks don't realize that's …

Setting PBO limits to motherboard or manual, means the CPU can draw as much power as it wants, which naturally leads to a nice performance boost, at the cost of the max temperature going up by 10-15 degrees Celsius.

Oct 2, 2021 · There's multiple places to adjust PBO settings in BIOS, some manufacturers even have 3 different places. OP is saying only use the AMD Overclocking section, which I thought was common knowledge, but apparently not.

Sep 26, 2021 · Why different behavior from PBO limit "Motherboard" + Ryzen Master to PBO limit "Manual" + same defined values? Additionally after Ryzen master does its first reboot with profile and applies settings.

Jul 14, 2022 · Pbo limits set to disabled keeps the 3 values at factory limits defined by the cpu, set to motherboard for crazy high limits set by the mobo manufacturer related to vrm supply limits, set to manual to define your own.

Feb 6, 2020 · Hello, i got a Ryzen 5 3600 and i'm wonder if turning on PBO is worth it. My Cinebench Score goes up to around 3630 when enabling it which is around 100 more than without, but also the temps go up from 70 to 80 degrees.

Dec 3, 2021 · What’s the easiest advanced PBO settings so my 5600x can hit 4.6ghz (asrock b450 pro4)
