EDC = 1, PBO TURBO BOOST - Overclock. net For single thread loads I've found EDC 10 and scalar 10x has worked best with a 3800X It will on occasion throttle to keep the EDC to target at idle or single thread load but all other applications usually work for multi-thread loads to have full boost capabilities Others have found that a 3950X likes EDC 25 and a 3960X likes one around EDC 30
Understanding the sizing and limits of PPT TDC and EDC EDC: 117 Run OCCT CPU stress and if you hit 100 percent on EDC in Ryzen master Up the EDC value in increments of 1 until you hit 98-99 never 100 To test the other 2 run cb15 20 all core watch it in real-time with hwinfo at 500ms Adjust TDC PPT based on your all core clocks with runs of cb 15 20
How PBO (mostly PPT TDC EDC CO) fundamentally works. . . Increasing EDC allows for you to set a more aggressive CO Setting mine to 200 allowed me to set an all-core -30, whereas at 160 I couldn't even get by at -20 on my best cores, -15 and -10 on the rest
TDC and EDC values - Overclock. net He never explains what you need to set TDC and EDC at I have an 7500f Trying to limit PPT from 88 (default) down to 75 Questions: 1: So PPT in bios should be 75000 But what do I set the other two at? 2: Curve Optimizer Would lower value of lets say -15 negative use less voltage, than having curve Optimizer disabled?
Guide - Fully optimise your PBO - Overclock. net After you got your EDC value you do the following, set EDC to double your value, yeah I can hear you thinking, "but why do we want to do that", well now we are going to use the CPU VDD Telemetry section 7a CPU VDD_SoC Current Optimisation: Custom Setting 7b CPU VDD Full Scale Current: The optimal EDC setting for your system as previously
