Question Nitro Rx480 8GB when put under full load, freezes the system

[Quanta Girl]

I have this Rx480 which i bought used from someone locally has this weird thing going on, when run with a benchmark software or a heavy game (I ran gta v), it freezes the system.
I tried flashing the latest available v-bios from techpower-up "Sapphire.RX480.8192.160603_1.rom"
even flashed bios from another working card, but nothing. So far, i have reached nowhere, but ya, if the load is like 50-60ish% it works fine. Help me if you can. I want to revive this card so bad.
Also the fan has a whiny sound.

so, I tried it for mining on nicehash, if mem and core and power limit are all underclocked, to max, max and -39% respectively it manages 10mhz.

I am a bit out of ideas.

However, to get a good mining hash rate you need to turn on compute mode:

Enable compute mode in AMD driver settings to increase the profitability of your RX470, RX480, RX570, RX580 GPUs up to two times. No additional apps or special drivers required. Here's how!

It is after switching to compute, and the video from yesterday, was when set to graphics
Normally this gpu is rated for anywhere b/w 25 and 32mhz but im getting 10 only after downclocking the power limit. I doubt if it is a faulty power delivery on the card or maybe something fried out. Idk?!

I think you have tried just about everything you can, which sadly I think just proves that the card has an issue

Not sure if you already tried this, but if not, a long shot would be to DDU it and start over software side.

i tried ddu twice but in vain. i am also certain that the card has some issue.smh
