Are you selling it or are you asking?

Never heard that someone can do that by optimizing the memory timings on GTX 10 series. Mostly rx470 or AMD cards are can be optimized without getting any issue.

Enlargement Pill only works in gddr5x Cards both GTX 1080ti and 1080.

If anyone knows it I hope they can share it here because there are many miners waiting to improve their old cards.
