@wnxod has generously shared images and screenshots that provide us with an initial glimpse of a special edition GeForce RTX 2080 Ti. Although the Turing architecture is now five years old, this top-of-the-line gaming card from that era is expected to deliver impressive performance.
Surprisingly, an individual managed to enhance this card by incorporating an additional 44GB of GDDR6 memory, surpassing its original configuration of 11GB across 352-bit. This unconventional memory setup provided an impressive bandwidth of up to 616 GB/s, comparable to that of contemporary gaming cards.
The identical board design is utilized for both the TITAN RTX, NVIDIA’s final gaming TITAN release, and the RTX 2080 Ti. The board has the potential for up to 24 memory slots on each side, although the other side remains unoccupied in the case of the RTX 2080 Ti. The modification process involves replacing the existing modules with 2GB capacity and doubling their quantity by installing modules on the back of the card.
The GPU-Z output verifies the presence of 45056 MB (44 GB) of memory operating at full bandwidth (616 GB/s). It seems that the card utilized for this modification was produced by Leadtek, who opted for the NVIDIA reference PCB design in their card.
Despite the sharing of GPU-Z and DirectX diagnostic info screenshots, it has been confirmed by the poster that the card does not function properly in games or benchmarks. This issue is often encountered with memory-modded GeForce cards, as they may necessitate a custom BIOS or specific adjustments to the NVIDIA Control power profile.
