I adjusted PPT to 75w in BIOS, yet the CPU continues drawing 77w - - - is this typical?
I adjusted the PPT to 75W in BIOS, followed all the steps from this video, and ran Cinebench for five minutes. However, my CPU still consumes 77W. The same reading appears in afterburner when playing MH Wilds. Previously it was 75W, but after enabling XMP in BIOS it jumped to 90W, so I had to reset the PPT again. Also, the CPU never exceeds 65°C in Cinebench, yet during gameplay afterburner sometimes shows 72°C and cools down rapidly to 61-64°C within seconds. Is this normal or indicates an issue?
Achieving 95C is the expected stock performance for Raphael (Ryzen 7000). To control this, you'll have to adjust all three limits.
Below are the ECO mode values for the 7600 and 7700, compared to the original specs.
Motherboard defaults usually set these higher than the stock configuration.
PPT Limit: 88000 (Recommended AMD stock 105W settings: 142,000)
TDC Limit: 75000 (Recommended AMD stock 105W settings: 110,000)
EDC Limit: 150000 (Recommended AMD stock 105W settings: 170,000)

Please note this was released before the update that increased power limits.
Adjusting RAM timing, speed, and voltage manually might be necessary instead of using EXPO presets.

I’m not a math specialist, but I calculated these extra options:
Difference & halved & halved:
PPT Stock 142k - ECO 88k = 54k /2 = 27,000 /2 = 13,500
TDC Stock 110k - ECO 75k = 35k /2 = 17,500 /2 = 8,750
EDC Stock 170k - ECO 150k = 20k /2 = 10,000 /2 = 5,000
Stock minus half Difference: <ECO+
PPT Limit: 142,000 - 27,000 = 115,000
TDC Limit: 110,000 - 17,500 = 92,500
EDC Limit: 170,000 - 10,000 = 160,000
Stock minus 1/4 Difference: <ECO++
PPT Limit: 142,000 - 13,500 = 128,500
TDC Limit: 110,000 - 8,750 = 101,250
EDC Limit: 170,000 - 5,000 = 165,000
Thank you for the details. I'll also check TDC and EDC. Appreciate the explanation👍
