Purchased the card not working.  I was able to clean, paste and replace all thermal pads.  Placed the card as a secondary in my test bench, reflashed correct vbios.  I now have it posting and displaying video.

The problem is it crashes when under a load.  It is not just one type of crash either.  If it is under heavy load it will full reboot the pc.  If it is a light load it will just crash the driver to desktop and repeat.

Normal operation like browsing and windows applications work fine. Temps are great.  But under heavy load it completely shuts off around 40c.

Any ideas?  Card looks clean otherwise

Thank you for your information and videos!
