sorry to hear your Micron VRAM eroded over time... if you open up GPU-Z, be careful with the reading of the voltage on VRAM "MVDDC"... micron when you OC and pushes, it can double the wattage on VRAM and killing it... Samsung VRAM don't fluctuate wildly
For Micron: make sure MVDDC power draw is between 30-32 watts, not 60-70 watts!

I have 2 Micron 3070, can you guess which 2? :)
