A pictures and screenshots shared by Cat T give us a very first look at a special GeForce RTX 2080 Ti graphics card. The Turing architecture may already be 5 years old, but the flagship gaming card from that generation should still give great results.

Turns out, they were were able to add 44GB of GDDR6 memory to this card, which originally features 11GB across 352-bit. This unusual memory design offered up to 616 GB/s of bandwidth, which is on par with modern gaming cards.

As modders have explained, they use Leadtek RTX 8000 PCB and replaced the GPU with TU102-300A (RTX 2080 Ti). Such a mod took many attempts (7 in total) and requires both a custom BIOS and drivers to work.

The GPU-Z output confirms 45056 MB (44 GB) of memory is installed at full bandwidth (616 GB/s). It appears that the card used for this mod was manufactured by Leadtek who are using NVIDIA reference PCB design for their card.

Even though GPU-Z and DirectX diagnostic info screenshots were shared, the card does not actually work in games or benchmarks, as confirmed by the poster. Memory-modded GeForce cards may require custom BIOS or special NVIDIA Control power profile changes, which is a common issue.
