Below are memory and performance results after applying the unlock:
Performance Benchmarks (OpenCL-Benchmark)
- Linux (x86-64)
- Root access
- NVIDIA CMP 170HX
- nvidia-open 610.43.0x already installed (libs + firmware)
- Kernel headers matching the running kernel (
linux-headers-$(uname -r)/kernel-devel) - Secure Boot disabled (patched modules are unsigned)
- Network access on first install (downloads matching stock
open-gpu-kernel-modulessources) - Python 3 (used at build time to select 8GB/10GB geometry)
To install cmpunlocker, run the following command:
sudo ./install.shTo force a certain memory profile, use the --profile option:
sudo ./install.sh --profile=8gb # 8GB card → 64GB unlock
sudo ./install.sh --profile=10gb # 10GB card → 40GB unlockThen perform a cold reboot (full power off, then boot).

| PCIe Gen 2 speeds | Working ✓ |
| Persistence across reboot (patched modules) | Working ✓ |
To uninstall cmpunlocker, run the following command:
