GPU Unlock on Windows
GPU Unlock does not have a Windows version. Both the original GPU Unlock and the GPU Unlock Ada fork are Linux kernel modules that run from the initramfs before the NVIDIA driver loads.
Why GPU Unlock is Linux-only
The unlock has to happen before the NVIDIA driver takes the card, and it has to happen again every time the card powers on. On Linux the module runs from the initramfs at exactly that point. The Windows experiments so far do the same job as UEFI programs that run before Windows starts.
What exists for Windows
- RTX 3070 Ti: the GPU Unlock README notes that the same unlock worked on an RTX 3070 Ti from a UEFI port on Windows. It has not been tested with the Linux module.
- RTX 4070 Ti (AD104): the Ada repository holds an experimental MSI RTX 4070 Ti Windows UEFI reference port contributed by Latence.app. It recorded one successful manual boot with NVIDIA 616.56 and cuBLAS gains of +80.1% FP16 and +76.4% BF16. It is tied to one captured MSI Z490 profile and ships no binaries or installer.
Neither is a ready-to-use Windows tool. If you want the unlock today, the supported path is Linux, including dual-booting a Linux install for AI work.
Beware of fake downloads
Because there is demand for a Windows version, expect sites offering a “GPU Unlock for Windows” executable. The official projects publish source code on GitHub only. Do not run firmware tools from unknown sources on your GPU.
Windows questions
Is there a GPU Unlock Windows version?
No. GPU Unlock and GPU Unlock Ada are Linux kernel modules, and neither project offers a Windows installer.
What is the Windows UEFI port?
The Ada repository includes an experimental reference port for one MSI RTX 4070 Ti on one MSI Z490 board profile, contributed by Latence.app. It recorded one successful manual boot. No firmware, Windows or ROM binaries and no automatic installer are distributed.
Can I use a Linux install and then boot Windows?
No. The Linux module only acts while Linux boots and nothing is written to the card permanently, so it is not a way to get the unlock under Windows.
Should I download a GPU Unlock .exe?
Be careful. Neither official project publishes a Windows executable, so a file claiming to be one is not from them.
See the Linux install guide or the risks.
