Question about disabled Cuda cores

Ok so this might be stupid but I thought it was worth a shot. The 560 ti 448 core gpu is a 570 with 32 cuda cores disabled. My question is, are the cores disabled by firmware, or are they physically disabled (i.e. blocked circuits, cores flat out removed, damaged, etc.)? I was thinking if it was just a firmware limitation, maybe I could flash 570 firmware and essentially "unlock" it.

Thanks!

I don't believe the 560Ti 448s are unlockable. Nvidia probably saw what happened with the reference 6950s being flashed into 6970s, and laser cut the CUDA cores to ensure you couldn't mod the 448s into 570s.

Even if they were unlockable, odds are the extra CUDA cores wouldn't all work properly, as the 448s were 570s that failed quality control testing.
