I set my PPT to 75W in BIOS, followed everything from this video, and ran Cinebench for 5 minutes, but my CPU still draws 77W. I also see the same 77W in afterburner when playing MH Wilds. Last week it was 75W, but after enabling XMP in BIOS, it reset to 90W, so I had to set the PPT again. Also, the CPU never go above 65C in Cinebench, but when I play games afterburner sometimes shows 72C and quickly coolsdown to 61-64C within seconds. Is this okay, or is something wrong?

Reaching 95C is intended stock behavior for Raphael (Ryzen 7000).
If you want to limit that, you'll need to change all three of these limits.

Listed here are the ECO mode numbers, compared to stock, for the 7600 & 7700.
(Motherboard defaults will often have these set higher than stock)

PPT Limit: 88000 (AMD stock 105W recommended settings: 142,000)

TDC Limit: 75000 (AMD stock 105W recommended settings: 110,000)

EDC Limit: 150000 (AMD stock 105W recommended settings: 170,000)

(numbers are courtesy of overclock3d.net)

NOTE: This was released prior to the update which extended the power limits

And setting RAM timing, speed and voltage may need to be done manually, instead of using EXPO presets.

I'm not a math expert, but I did figure these optional settings:

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

Appreciate the info ill look into adjusting TDC and EDC as well. Thanks for the breakdown👍
