Ofc this is fasle. But probably amd locked somehow. I dont know.
See, all cpus 9xxxx have this 180A lock limit. But for 9700x it WAY higher than it can consume.
And we have situation where 9950x crippled by this limit and in another side 9700x and 9600x where with this limit we can blow up them.
So, the limit is
TDC =180A
EDC = 250A
PPT = 1000w.
Why the hell do we need 1000w ppt with 180A TDC, knows only the guy who tweaked this number...

No AMD didn't locked anything all this current and power limits are set by the motherboard OEMs for most likely nefarious purpose like artificial market segmentation just like they do with the POST CODES DISPLAY and i beyond upset with this stuff.:mad:

ASROCK! Same here with my B650E Taichi. Stuck and 1000/180/250
Click to expand...
The same with X670E Taichi, last BIOS 3.08 AMD AGESA PI 1.2.0.2.
at the time of purchase this was the top of the line motherboard from Asrock
and I was in no way expecting such surprises.
Was bought specifically for overclocking....
Can't get more than 45400 in CB23.

Asrock Answer:
TDC limit 180A is a value decided by AMD AGESA.

We do not change this value for R9 7950X.

Yes! These are may be the default AGESA settings for the CPU, and should be disabled
if you set your values in PBO Limits or select the “Motherboard” setting.

Gikinjapan, would really appreciate your help.
I'm afraid they will answer me as well as above .... - "... AGESA....We do not change this value for R9 7950X. "

Hey mate, we are trying to collect some info about limits on different motherboards.
Could you run prime95 with AVX512 instruction set?
Make sure that you running it with AVX512 and in the bios your TDC more than 260A and EDC more than 290A.
In HWinfo I need you TDC current in ampresr.
Or insted Prime95 you could show Ryzen mater, first tab with TDC and EDC limit.
For example you could look here

Guess I'll have to sell Taichi x670e and get an Asus x670e HERO (may be x870e Hero).
Asrock boards are not suitable for overclocking 12 or 16 core CPUs.

The problem hasn't been solved since last year and there is no hope that they will fix it.

They limited the top-end board as well as the budget ones.
Possible to set the PPT in 1000 watts, but the TDC 180A does not allow you to reach more than 240 watts.

Same here. Been looking at boards and pricing... Hopefully I can recoup some of the cost by selling the B650E. Didn't but a flagship CPU to be limited in its performance.
