Topic: Bricked 470 GPU damaging whole rig. Help needed (Read 529 times)

First thing I would do is use a BIOS from one of your other cards if they are the same card. One BIOS from same card may not necessarily be the same since it is could be a different revision.

Now to performance issue with that card being slower maybe to the memory quality even same memory is not exactly to same specs as another one on a different card. So you have to use Wattman and play around with the settings for the one card. Some require less power than others.. so you have to figure out does it need more or less power?  Is memory over clocked too much or do you need to boost it?  Each card is different and no one setting is same for all cards.  I have 6 RX 480 of same card and most are set at a general setting but 1 or 2 have custom settings to bring them to par with the other cards.  They consistently get about 27-28 MH/s for eth..  But I am using a dual miner so that is quite good for eth mining rate.

TIP: Never flash BIOS before doing a backup of the stock BIOS.

Hello everyone, today Im in need of all your wisdom! I hope someone of you can help me.

the story:
3 days ago I had 4x RX 470 8gb working around 26mh/s (micron) and my fifth only did ~22. So I looked for further improvements since my brother has the same card with 29mh/s.
Looked around the internet and downloaded some BIOS (great mistake). Flashed the card and nothing worked anymore. Long story short after 2 days of pure setbacks Ive managed to flash a working BIOS onto the said card which was totally bricked (no pc at all would boot with it no matter if it is the main card or not, was not able to change BIOS via bootable stick and atiflash). I dont know if it is possible but my other cards also seemed to act weird since the incident.

Well now I have managed to get the BIOS which works with my other cards onto the damaged one but it is still not working. Plugging a HDMI cable onto it will just result in no signal at all. Here is what afterburner and GPUZ says (1, 2):

So the result until now is the following:
Both PCs (the rig and another one) are acting weird since I have plugged this card onto it. The SSD is always on 100% utilization (processes only take 0,3-max 5 MB in TOTAL) (3)
The SSD on my rig is also not working anymore I guess. Booting my rig I instantly get the screen in picture (4) and is stuck there.


So right now my rig is not working at all anymore.
I dont really know what to do and where to start.. Is it possible that a bad BIOS damages the Mainboard or SSD?
Do you have any suggestions I should try to fix my problem near future 
At least Im happy that I managed to flash the card after 2 days (even though it might be gone forever..) What should I try to do with the card?

ANY advice is highly appreciated!
