I did a power profiling on a

with the command:
./AMDuProfCLI timechart --event power --interval 100 --duration 100

When I evaluated the CSV-file under full load("stress-ng -t 120 -l 100 -c 256 --cpu-method all") of the server I can see:

Average Power of socket 1: 204W
Average Power of socket 2: 201W
Average Power of cpus: 268W

Is the complete power consumption of the server now: 204W+201W+268W=673W ?
Or do I miss something like power consumption for memory?

Best regards

No ideas?

Hello,

I am also using this CPU "AMD Epyc 7742 and has 64 cores with 128 threads and based on 2. gen of the AMD Epyc series."

But i want to achieve 256 threads. Would you please tell me how  would it be possible. Thanks!
