GPU Mining (keryx-hash)

• keryx-miner-supr RECOMMENDED v0.4.0

  No prebuilt Windows binary yet — easiest path is WSL2 (Ubuntu) with the Linux instructions above, or build from source with MSVC + CUDA 13.0 + Rust 1.78+. source git clone https://github.com/ocminer/keryx-miner-supr cd keryx-miner-supr $env:CUDA_COMPUTE_CAP=120 cargo build --release .\target\release\keryx-miner-supr.exe -a keryx:YOUR_KERYX_ADDRESS.rig01 -s stratum+tcp://krx.suprnova.cc:4404 --light --cuda-device 0 Windows Defender flags every GPU miner on first run — whitelist the folder. If you'd rather not build, use the upstream keryx-miner Windows zip below.

• keryx-miner upstream prebuilt v0.3.2-OPoI

  Single zip, supports both AMD and NVIDIA. Download (21 MB), right-click → Extract All, then run in PowerShell or cmd.exe: keryx-miner.exe -a keryx:YOUR_KERYX_ADDRESS.rig01 -s stratum+tcp://krx.suprnova.cc:4404 --light

• Rental marketplace support — pending

  Keryx's keryx-hash algorithm is GPU-based and verifier-bound (kHeavyHash + KERYX_MATRIX_SALT + WaveMix ARX). Major rental marketplaces like Nicehash and Mining Rig Rentals do not list it yet. We'll publish a connection guide here as soon as a marketplace adds keryx-hash. In the meantime, run keryx-miner on your own hardware against port 4404.

HiveOS Flight Sheet Setup

• Step 1: Create a Flight Sheet

  Go to Flight Sheets in your HiveOS dashboard and click Add Flight Sheet. Set the following:

  Coin	Select Custom, enter KRX
  Wallet	Create a new wallet with your KRX wallet address, or select an existing one
  Pool	Select Configure in miner
  Miner	Choose one of the miners below (see Step 2)

• Step 2 (recommended): keryx-miner-supr — Custom Miner RECOMMENDED v0.4.0

  The Suprnova fork ships native sm_120 PTX, an unrolled Keccak-f1600 round loop, and built-in OC / monitoring flags. A prebuilt v0.4.0 tarball is published on GitHub — no self-build required. Follow the six steps below to wire it into a HiveOS Flight Sheet from a blank slate.

  RTX 5090 · sm_120 3.28 GH/s stock · +28% vs. upstream

  A

  Open Flight Sheets → Add Flight Sheet

  In your HiveOS web dashboard, expand Flight Sheets in the left sidebar, then click the blue + Add Flight Sheet button. A new empty sheet panel opens on the right.

  B

  Coin → Custom → ticker KRX

  Open the Coin dropdown and scroll to the bottom — pick Custom. A ticker input appears beside it. Type KRX and confirm. HiveOS does not validate custom tickers, so spelling matters.

  C

  Wallet → pick or create your KRX wallet

  In the Wallet dropdown, choose an existing wallet — or click + to add one. Paste your full keryx:… CashAddr address and name it (e.g. krx-main). HiveOS will substitute this wallet anywhere the %WAL% template appears in step E.

  D

  Pool → Configure in miner

  Open the Pool dropdown and scroll to the very bottom — pick Configure in miner. This bypasses the HiveOS pool selector entirely; we'll bake the stratum+tcp:// URL straight into the miner's CLI in step E. (Picking a preset pool here can override our flags silently.)

  E

  Miner → Custom → Setup Miner Config

  In the Miner dropdown, pick Custom. A Setup Miner Config button appears below — click it. Fill the dialog with these exact six values; every field matters:

  Installation URL	https://github.com/ocminer/keryx-miner-supr/releases/download/v0.4.0/keryx-miner-supr-0.4.0.tar.gz
  Miner name	keryx-miner-supr
  Hash algorithm	keryx-hash
  Wallet template	keryx:%WAL%.%WORKER_NAME%
  Pool template	krx.suprnova.cc:4404
  Extra config arguments	--light --cuda-device 0

  Tier flag (last arg) — pick by VRAM: --light = any GPU ≥ 6 GB (TinyLlama, safest) · default = 12 GB+ (adds DeepSeek-R1-8B) · --high = 24 GB+ (adds R1-32B) · --very-high = 32 GB+ (adds LLaMA-3.3-70B). The tier only affects optional AI-task eligibility — PoW hashrate is identical.

  F

  Save · Apply · watch the log light up

  Name the flight sheet (e.g. KRX-supr-v0.4), click Create Flight Sheet, then Apply on your rig. The worker pulls ≈ 7 MB, extracts to /hive/miners/custom/keryx-miner-supr/, and starts the binary. Open the rig's Miner log tab — within ~30 seconds you should see SHARE accepted lines. Your hashrate then appears on Your Stats → a moment later.

  Building from source instead? Clone github.com/ocminer/keryx-miner-supr, run cargo build --release against CUDA 13.0 (not 13.2 — driver 580 caps PTX at ISA 9.0), then tar the workspace's target/release/keryx-miner-supr together with libkeryxcuda.so and libkeryxopencl.so. Host the archive on any HTTPS URL the rig can reach and substitute it for the Installation URL above.

• Step 2 (AMD GPUs): keryx-miner-supr-amd — Custom Miner AMD / OpenCL v0.4.0

  Same Suprnova fork, OpenCL build for AMD Radeon & Instinct GPUs. The binary dlopens libkeryxopencl.so shipped alongside it and finds all AMD GPUs via the AMD/ROCm runtime that's already on the HiveOS rig. Auto-tuned per-arch workload sizes — gfx906 (MI50) uses 2048 nonces-per-dispatch, gfx1102/RDNA3 uses 4096 — no manual tuning needed.

  RX 7600 XT · gfx1102 ~332 MH/s RDNA3 · v_dot8 packed matmul

  CMP MI50 · gfx906 ~421 MH/s thermally capped · 0 rejects

  Archive size 5.8 MB OpenCL · sha256 be60052f…

  Steps A–D are identical to the NVIDIA variant above. The only difference is step E — use the AMD release URL, the keryx-miner-supr-amd miner name, and the OpenCL device flag:

  Installation URL	https://github.com/ocminer/keryx-miner-supr/releases/download/v0.4.0/keryx-miner-supr-amd-0.4.0-hiveos.tar.gz
  Miner name	keryx-miner-supr-amd
  Hash algorithm	keryx-hash
  Wallet template	keryx:%WAL%.%WORKER_NAME%
  Pool template	krx.suprnova.cc:4404
  Extra config arguments	--light --opencl-device 0

  Optional flags: --opencl-device 0,1 mines on specific GPU indices (default: all). --opencl-workload N overrides the per-arch nonces-per-dispatch default — only touch this if you've benchmarked. --disable-gpu falls back to CPU mining (testing only). Tier flag tiers (--light / --high / --very-high) gate optional AI-task eligibility by VRAM and don't affect PoW hashrate.

  NVIDIA & AMD on the same host? Both packages install side-by-side — different miner names (keryx-miner-supr vs keryx-miner-supr-amd) and distinct install paths (/hive/miners/custom/keryx-miner-supr-amd/). Pick the one matching the rig's GPU brand in the flight sheet's Miner dropdown.

• Step 2 (alternative): keryx-miner Built-in v0.3.2-OPoI

  keryx-miner ships built-in with HiveOS — no Custom Miner install required. The built-in image may lag a release or two behind; for the freshly-released v0.3.2-OPoI (Windows keryx-hash + GPU-class hashrate tuning), use the Custom Miner option in the box below instead.

  Miner	Select keryx-miner from the miner dropdown
  Algorithm	keryx-hash
  Pool URL	krx.suprnova.cc:4404
  Wallet	%WAL% (just the address — no .%WORKER_NAME% suffix)
  Worker name	%WORKER_NAME%
  Password	leave blank — unused by this stratum dialect

• Step 2 (alt): Custom Miner — keryx-miner v0.3.2-OPoI latest

  If your HiveOS image doesn't ship keryx-miner v0.3.2-OPoI yet, install upstream's Custom Miner package directly. In the Flight Sheet, choose Custom in the Miner dropdown, then fill the fields below.

  Installation URL	https://github.com/Keryx-Labs/keryx-miner/releases/download/v0.3.2-OPoI/keryx-miner-v0.3.2-OPoI-linux-gnu-amd64.zip
  Miner name	keryx-miner_custom (auto-filled from the archive)
  Hash algorithm	keryx-hash
  Wallet template	%WAL%
  Pool template	krx.suprnova.cc:4404
  Extra config arguments	-a keryx:%WAL%.%WORKER_NAME% -s stratum+tcp://krx.suprnova.cc:4404 --light

  All flags must be set in Extra config arguments — the custom-miner archive contains the binary only, no auto-config. keryx-miner parameter reference: github.com/Keryx-Labs/keryx-miner/Parameters.

• Step 3: Apply and Start

  1. Save the flight sheet and apply it to your worker(s). 2. The miner starts automatically. Check the Miner log tab and look for SHARE accepted lines. 3. Your stats appear on Your Stats within a few minutes. Tip: Port 4404 (VarDiff) is the recommended port for GPU rigs — it adapts automatically and converges in ~2 minutes. Use 4401 for CPU / laptop / small GPU.

• TL;DR — Quick Copy & Paste (HiveOS) no-fuss

  Skip the tables — just paste these three lines into a fresh Custom Miner flight sheet. Wallet is your KRX address; HiveOS auto-fills %WAL% and %WORKER_NAME% from the flight sheet's Wallet field and the rig's worker name.

  Installation URL

  https://github.com/Keryx-Labs/keryx-miner/releases/download/v0.3.2-OPoI/keryx-miner-v0.3.2-OPoI-linux-gnu-amd64.zip

  Hash algorithm

  keryx-hash

  Extra config arguments

  -a keryx:%WAL%.%WORKER_NAME% -s stratum+tcp://krx.suprnova.cc:4404 --light

  That's it. Save the flight sheet, apply it to the rig, and shares start landing within ~30 seconds. krx.suprnova.cc:4404 is the recommended VarDiff High port and works for any rig from a single GPU to a multi-card farm. For small / laptop GPUs use port 4401 (VarDiff Low) instead.

MMPOS Configuration

• MMPOS Setup v0.3.2-OPoI supported

  MMPOS configuration mirrors HiveOS. Pick keryx-miner from its miner list and configure the same fields. If MMPOS hasn't picked up keryx-miner v0.3.2-OPoI yet, install upstream's Custom Miner archive (URL below) the same way HiveOS does.
