"Fixing" the BIOS will not bring that card back. The GPU itself is toast, WELL Toasted...
Surin that core of that gpu is cracked. The electrical traces and transistors are not in tact anymore. Stop fooling yourself, Move on and Get a 3850 or 4670.
Cracked, Melted, Burnt. Pick your adjective, it's beyond help.
card is toast thats not burnt thermal pastes thats where the core melted lol
GPUs will similarly suffer meltdowns running at high temperatures for prolonged periods of time. If you surf the hardware support sites, you will realize that the occurrence of GPU meltdown far exceeds CPU meltdowns. cpus are rated for max 95°C-105°C "200°F-225°F" normally.
One advantage GPU has over CPU is that they usually have a larger area to play with in terms of heat dissipation, at the same time the GPU chip is not constrained to a die as small as a CPU, thus enabling a GPU chip to have better tolerance.
At the same time, CPU thermal shutdown is usually set conservatively - most BIOSes by default shut down the CPU when it hits 70°C. Unless you manually override the BIOS settings, it is not often a CPU gets pushed beyonds its limits (thus having less reports, and perceived lower failure tolerance).
However, GPU overclocking is extremely common, and many situations arises where people push GPUs to extreme temps - thus resulting in a perception that GPUs have higher temperature tolerances than CPUs. Not true - I have seen CPUs go up to 100°C "212°F" and still remains stable.
so your gpu is fine if you didn't manually overclock. And a gpu cannot crack up before it hits higher tempratures than the pcb can handle but that wont ever happen since the solder connected to the gpu will melt and become non conductive before pcb or gpu died totally. if you use Liquid Nitrogen it can cause cracks to cpus or gpus.
baking a gpu in a oven exceeds overclocks and even solder limit of melting, and gpu still doesnt crack or die #baking for around 8 minutes at 385°F=196°C#
baking is often used to fix old cards
lowest average melting point for electronic solder is around 375°F = 190°C
Maban's cpu was once under 100°C+ and hes using it fine, i still managed to get 5ghz out of it at a later time even tho it was on 100°C+ for many hours when my pump stopped
so gpu cracking if not under a torch isnt possible
