Memory Unlock Results

Performance Benchmarks (OpenCL-Benchmark)

Requirements

• Linux (x86-64)
• Root access
• NVIDIA CMP 170HX
• nvidia-open 610.xx.xx+ 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-modules sources)
• Python 3 (used at build time to select 8GB/10GB geometry)

Install

To install cmpunlocker, run the following command:

sudo ./install.sh

To 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 unlock

Then perform a reboot.
