gpu-unlock compatibility and performance on CachyOS with RTX 3080, including initramfs integration.

Technical Positioning
gpu-unlock aims to provide reliable FP16/BF16 performance unlocking on Nvidia 3000 series GPUs across various Linux distributions, ensuring bit-identical outputs.
SaaS Insight & Market Implications
This compatibility report confirms `gpu-unlock`'s successful operation on CachyOS with an RTX 3080, demonstrating significant FP16/BF16 performance gains (65 to 110-113 TFLOPS) and crucial bit-identical outputs. This validates the core value proposition of performance enhancement without compromising numerical precision. The identified `mkinitcpio systemd-hook drop-in bug` highlights a common developer pain point: ensuring proper module loading order and configuration across diverse Linux initramfs implementations. While a fix was needed, the detailed reporting and suggested solution indicate a path to improved distribution compatibility. Market implications are positive, expanding `gpu-unlock`'s reach to Arch-based distributions and reinforcing its reliability for AI/ML workloads where both speed and accuracy are paramount.

Raw Developer Origin & Technical Request

Source Icon GitHub Issue Oct 23, 2026
Repo: Zagitta/gpu-unlock
Compatibility report: works on CachyOS, RTX 3080 10 GB (PNY) - ~110 TFLOPS FP16/BF16, bit-identical outputs + mkinitcpio systemd-hook drop-in bug

**Result:** Unlocked (`pci 0000:02:00.0: gpu_unlock: unlocked`), driver loads normally, zero Xid/NVRM errors. FP16/BF16 with FP32 accumulation goes from ~65 to ~110–113 TFLOPS at the stock 320 W limit, and GEMM outputs are bit-identical before and after.

**One fix was needed:** on a `systemd`-hook initramfs, the packaged drop-in's `gpu_unlock?` entry is never loaded. Details and a suggested fix are in the last section below.

### System

* **GPU:** PNY GeForce RTX 3080 10 GB (`10DE:2206`, subsystem `196E:136D`) at `0000:02:00.0`, VBIOS `94.02.26.C0.03`, PCIe 4.0 x16. No monitor attached; it renders a KDE Plasma (Wayland) session on a virtual display that is streamed over Sunshine.
* **Host:** Intel Core Ultra 9 285K, Gigabyte Z890 AORUS PRO ICE (BIOS F20), 32 GB DDR5 (at 4800 MT/s)
* **OS:** CachyOS
* **Kernel:** `7.2.9-1-cachyos` (DKMS also built for `6.18.55-1-cachyos-lts`; that kernel's initramfs was checked but not booted)
* **NVIDIA driver:** `615.71.09`, open kernel modules (`linux-cachyos-nvidia-open`), CUDA 13.0 in the test container
* **Boot:** Limine 12.9.0 with `limine-mkinitcpio-hook` 1.39.0, mkinitcpio 42.2 with the `systemd` hook, systemd 262
* **Kernel cmdline:** `... gpu_unlock.targets=0000:02:00.0`
* **Secure Boot:** off (module unsigned, kernel tainted as expected)
* **Power:** stock 320 W limit, no undervolt or clock offset

### Install

* `makepkg -f` in `packaging/arch/`: the pinned inputs downloaded and checked, the firmware was generated, and...

I've seen some other reports that supposedly it works for AD102 as well but I don't have a card to test on myself. I'm happy to expand the allowed device IDs to AD102 as well if I see concrete evid...
CannaraX • Oct 23, 2026
This would be definetly also interesting for 4070 Ti Super, as it also uses the AD103. I have this GPU here, so I could test this if somebody gives me a small guide on what to modify and what tests...

Re-posting here rather than as a separate issue, since AD10x support was already discussed in this thread. Three AD106 cards (RTX 4060 Ti, `10de:2803`), cold boot, no driver bound, `driver=`, `stat...
