Modified GeForce RTX 4080 Cards Appear With 32GB of GDDR6X

Unofficial GeForce RTX 4080 cards with 32GB of GDDR6X memory have appeared on the Chinese second-hand market. A normal RTX 4080 provides 16GB across a 256-bit interface. The modified cards replace or repopulate the memory devices to double capacity without changing bus width or memory bandwidth. Extended CUDA memory tests and sustained workloads are more useful than a screenshot from a system-information utility.
