Stock power limits are 88W PPT - 75A TDC - 140A EDC

Here's a YouTube Video on configuring Ryzen 7000 series power limits and curve optimizer for lower temps.

Ryzen R7 5700X | B550 Gaming X | 2x16GB G.Skill 3600 | Radeon RX 7900XT
Ryzen R7 5700G | B550 Gaming X | 2x8GB G.Skill 4000 | Radeon Vega 8 IGP
Ryzen R5 5600 | B550 Gaming Edge | 4x8GB G.Skill 3600 | Radeon RX 6800XT

What number do you think ı should limit the tdc and edc  ? Im setting up the ppt as 75w and curve optimizer to -20.Im a real rookie about undervolting so ı really appreciate any help you can give

A 65W TDP processor like my 5700X had stock power limits of 76W PPT - 60A TDC - 90A EDC you could start with those. Open Ryzen Master and run Cinebench Multi-Core benchmark, then monitor the power gauges and adjust the CO offset and Limits to suit what temperature and boost frequency you're aiming for.
