MSI RX 470 ARMOR 4GB with limited frequency

[Traptor]

Hi folks,
I have got an MSI RX 470 ARMOR 4GB GPU with a problem and I dont know where can I start repair and if it is worth it.
The card erlier life is unknown.

The problem is that: when I start gpu test (Furmark Heaven Benchmark) no problem - no artifacts or something - but after a little time and then the pc is rebooting.
I tested the gpu with tserver:
The test with maxmimum memory frequency is OK
./agt -mem=1650
./tserver -boardtest=memfa

But, if I increase the engine frequency I have got error. Whit this parameters the test is freezing:
./agt -eng=1230
./tserver -boardtest=memfa

I loaded the bios to bios editor and I saw this table (in attachment).
So I decreased the engine freq and my case is eng=1147MHz is fully OK.
In windows I fixed the maximum freq to 1147MHz and now every test is fine.

My questions are:
- what is wrong in gpu? I cant imagine where can I start.
- is it fixable or is this gpu dying?
- could I modify the bios and set the 1147MHz limit?

Thank in advance the help.

Is it possible you only get a crash at idle speed when the voltage goes low? That table of voltage is suspicious to me. If you are locking the speed in Windows maybe it never goes low?

I would get a compatible BIOS from tech powerup .com and open it with the editor and see if your BIOS is correct.

Alternatively you could make it so the lowest mhz/mv setting is the same as the second lowest, so maybe it won't crash? I am more familiar with Nvidia, I don't know much about the AMD hacking.

Whether it is worth it depends on what you have a use for it, and if you like fixing; spending many hours working on problem. I bought RX580 2048SP 8GB for $40, and saw 5700xt for $97, so the usefulness of your card may be limited in future.

Thank you for your answer.
I have got explanation from an expert: that problem means the degradation of gpu chip.
The solution is the modified bios with limited frequency or the gpu chip replacing.
