Apr 30, 2021 · PBO is just stock operation with some limits adjusted. Overall performance should only be slightly better. Also don't manual oc on ryzen it's basically pointless. AMD basically runs their latest chips at the red line out of the box and the only real performance to be gained is with PBO + high speed memory.

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.

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.

Disabling the PBO limits has the benefit of increasing performance, without getting higher temperatures. Optimum tech's video is mostly an undervolting guide , rather a full OC guide with PBO. 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 ...

Oct 2, 2021 · I know on gigabyte there's XFR section for PBO and then Amd overclocking. This one has the scallar and auto oc which xfr doesn't have. If you stick to just PBO, XFR section will have better boost on old agesa. New agesa amd overclocking is better. But new agesa the PBO is already nuked on Zen2. F11 goes to 200w, F34 caps at 165w or so.

Jul 14, 2022 · I watched the OptimumTech guide on undervolting with PBO2 and he said to disable PBO Limits to load the CPU's stock power profile (PPT, EDC, etc.). If I set my own PPT values (AMD CBS -> XFR Enhancement in Gigabyte B550I BIOS), for some reason I still see them reflected in Ryzen master even though PBO Limits are set to disabled.

Sep 26, 2021 · Wont show up in normal gameplay. The top one is the PBO. PBO is a whole lotta hassle for next to zero benefits, for me. I can gain more 1% and 0.1% fps if I had dualrank RAM. Because I tested that too. With dualrank (4 sticks SR) at 200 Mhz lower RAM speed I gained 1 fps avg and 2-4 fps on the lows. What do you know, better than PBO does.

Feb 6, 2020 · PBO helps more in single threaded apps (games) than it does in Cinebench. In general I'd say it's worth it as long as the temps are reasonable. You could try to undervolt the CPU in BIOS, which will help with the temps. Ryzen …

Dec 3, 2021 · I compared the Auto and Disabled settings to different Advanced settings. In the bios I set PBO Advanced settings PBO Limits to Motherboard, PBO Scaler to Auto, Curve Optimizer to negative 30, 30, 8, 30, 30, 30, Boost Override to 0, 50, 100, 200; and Thermal Throttle limit to Auto. I got OCCT errors in Core 2 down to -8, all others were ok at -30.

Jul 18, 2023 · Here are my PBO settings: Core 0 -30 Core 1 -15 (My fastest core based on ryzen master) Core 2 -30 Core 3 -30 Core 4 -30 Core 5 -20 (My 2nd fast core) Core 6 -30 Core 7 -30 For frequency ccd, I didn't do anything to it.
