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
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
Tuning your 5800x - Offering my experience to help you tune yours Setting the negative offset seems to bring the whole PBO curve down My understanding is the PBO curve is shaped like a funnel and the higher the loads, the less the curve takes out of the set voltage If you want higher boosts, use less negative offset but you may end up with less MHZ under full load because now you are hitting the PPT Limit
What is PBO Scalar? : r Amd - Reddit In my research it holds voltage longer with PBO to hold the higher frequency? This comes at the cost of temperature obviously but when i set a X10 scalar it doesn't just hold higher voltage it applies 0 5v more all the time to core VID I have a custom water loop with CPU under its own 560mm rad Temps aren't an issue Is it worth running scalar?
Ryzen 5 5600 optimization : r Amd - Reddit Set PBO limits to unlimited PPT, increased TDC (e g 80), increased EDC (e g 160) Set Curve Optimizer to -25 on all cores - how stable this will be is entirely dependent on silicon lottery, but -25 on all cores is 100% stable for me Going to -30 was mildly unstable Max boost clock override (AutoOC) +200 MHz
7800X3D Curve Optimizer Question(s) : r overclocking - Reddit I built my first pc couple of weeks ago and I limit vsoc to 1 2njust for precaution and saw many posts about the PBO and curve optimizer so I set it to -20 I know CO allows my cpu to run beyond its limit for better performance, but what exactly does it do? Does it affect performance in gaming? Does it lower temps or increase them?
Ryzen 9 7950X performance to power limit scaling - (Actually . . . - Reddit PBO allows running the CPU with higher power and current limits, potentially allowing it to boost higher and longer compared to stock PBO2 (Zen3 Zen4) also has a subsection which is Curve Optimizer, which can be used for undervolting or overvolting, either the whole CPU, per CCD, or per core
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
7950x3d curve optimizer settings? : r Amd - Reddit I 100% dont recommend ryzen master It fked everything up on my pc It wasnt even starting anymore to Windows I just set my pbo to -20 turned off Expo for the ddr and configured it manually to 6000mhz with the template of that youtuber (forgot the name of the channel) and it works perfectly smooth now
