Nvidia CMP 170HX mining GPUs hacked to unlock 64GB VRAM

By PulseAugur Editorial · [2 sources] ·

A software modification called CMP Unlocker has been developed to restore previously disabled VRAM on Nvidia's CMP 170HX cryptocurrency mining GPUs. This hack allows the cards to access up to 64GB of VRAM, an eightfold increase from their original 8GB capacity, and also restores some computational performance and faster PCIe interface speeds. The CMP 170HX, based on the GA100 Ampere silicon used in the A100 accelerator, had its memory disabled by Nvidia for product segmentation, though it's unclear if some disabled memory was due to physical defects. AI
