It took me some time and alot of stress tests to figure out a stable setting: Curve optimizer magnitude (-20, -10, -25, -25, -25, -20, -20, -10) If not I thought about setting pbo in bios to motherboard and I'm not sure if it's best to have curve optimizer on per core or all core, so I thought about either putting it on auto or stability testing it each core, but again, not sure if I absoulutely need to find the highest and most stable ppt edc and tdc. That nets CB r23 result 16000+ with all core frequency of about 4860MHz, single core 1650 at best core at 5005MHz all with voltages up to 1. I've found out that CCD0 (0,1,2,3,4,5) maxes out at -14 while CCD1(6,7,8,9,10,11) can handle -30It seems that all cores belonging to a CCD actually behave the same, I will try some find tuning to see if tehre is any real difference between the cores on CCD0 Aug 5, 2021 · Curve optimizer, in and of itself doesn't alter voltage, it alters the boost frequencies at a given voltage. May 14, 2022 · Precision Boost Overdrive 2. Voltage offset removes a flat amount of voltage at all points of the frequency curve - but without actually affecting the curve. Unlike the standalone PBO option, Curve Optimizer requires manual testing and configuration to find your ideal undervolt, and will require quite a few system restarts before you find the best configuration. PBO is auto, voltage is auto and whenever i begin messing with PBO i get lower scores in cinebench. OverclockZone Member. 0 + Auto OC + Curve Optimizer - 11,658 all core, 656 single core (11,740/661 was attained but had stability issues, see "Curve Optimizer" below) Now my settings: PBO Limits: Motherboard PBO Scalar: 3x Max CPU Boost Override: 200mhz Apr 2, 2019 · But it's all pretty irrelevant: if set up right with PBO and curve optimizer you won't crash with CB, P95, Linpac or F@H (unless cooling is completely inadequate. Apr 16, 2022 · AMD has updated Ryzen Master to include the curve optimizer directly within the app and provides support for the Ryzen 7 5800X3D and Threadripper Pro 5000WX CPU lineup.
