Obviously, the team has a lot of experience but it's still impressive that they managed to bring this feat to a successful end. Once the card was finished, it booted without a problem. The RTX 2080 Ti's BIOS even automatically recognizes the GDDR6 and runs it at 16Gbps without requiring BIOS modding.
Long story short, it worked. The limitations of the memory controlled prevented TecLab from achieving even higher clocks, but they ended up at 2250 MHz (17200 MHz effective), which is 3200 more than stock 14 GHz.
