What the hell is PBO for Ryzen? : r Amd - Reddit 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
What is PBO and is it safe? : r buildapc - Reddit 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
PBO Limits: Disabled vs Manual? : r overclocking - Reddit 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
Set and forget 5600X PBO, Curve Optimizer -30, which tests for . . . - Reddit 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
Best PBO settings : r ASRock - Reddit 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
PBO Doesnt Do What You Think It Does | Precision Boost . . . - Reddit PBO might be needed to power the CPU to hit these higher potential boost clocks, but again this is useless in most cases because the Ryzen 3000 chips hit the temperature limit before they reach their even their stock max boost clocks on all core, so increasing the limit on paper doesn't help when the thermal headroom isn't there to do it in
Precision Boost Overdrive (PBO) worth it? A few questions. 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 Balanced is the most often recommended plan
Guide: Zen 3 Overclocking using Curve Optimizer (PBO 2. 0) PBO 2 0 w Curve Optimizer: Undervolting is a way of overclocking CPUs and GPUs that have an internal table that maps voltage to operating frequency Basically, a 50mV undervolt tells a CPU that instead of operating at, say, 2GHz at 1V, operate at 2GHz at 0 95V instead, and whatever frequency is mapped to 1V is now >2GHz
Question about PBO scalar x10 : r Amd - Reddit The auto options don't work PBO doesn't work Manual OC is apparently too dangerous due to static voltages Ryzen 3700 and PBO has been a complete failure and pure disappointment for hitting advertised boost clocks Not only for the performance, but a complete lack of OC guides that show any meaningful benefits
Ryzen PBO limit - motherboard vs manual : r overclocking - Reddit 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
