Get mining in 3 steps
1 Your C64 address

Paste the C64 wallet address you want rewards paid to. The worker name (e.g. rig01) just labels this machine in Your Stats.

2 Choose a miner

3 Region & connection

Bigger CPU? Try port 6465 (mid) or 6466 (high) for faster VarDiff — same address.

Your connect command

Download: github.com/ocminer/cpuminer-opt-supr/releases — Windows users add .exe to the binary name; full per-OS instructions are below.

Hashrate Rental Services
  • Nicehash / Mining Rig Rentals
    Support for Nicehash and Mining Rig Rentals for RandomX (rx/c64) is coming soon. Use port 6468 (high difficulty, optimized for rental hashrate) when connecting via these services. We will provide a detailed guide once these services add support for rx/c64.
  • Octa.Space Available Now
    You can rent CPU hashpower on Octa.Space. Pool URL: stratum+tcp://c64.suprnova.cc:6468
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 C64
    Wallet Create a new wallet with your C64 wallet address, or select an existing one
    Pool Select Configure in miner
    Miner Choose one of the miners below (see Step 2)
  • Step 2a: SRBMiner-Multi Easiest
    SRBMiner-Multi is a built-in miner in HiveOS — no custom installation needed.
    Miner Select SRBMiner-Multi from the miner dropdown
    Algorithm randomc64
    Pool URL stratum+tcp://c64.suprnova.cc:6464
    Wallet %WAL%.%WORKER_NAME%
    Password x
    Extra config --disable-gpu
  • Step 2b: cpuminer-opt-supr Recommended
    cpuminer-opt-supr is a Custom Miner in HiveOS. You need to provide the installation URL.
    Miner Select Custom at the bottom of the miner dropdown
    Miner name cpuminer-opt-supr
    Installation URL Copy the .tar.gz link from GitHub releases
    Hash algorithm c64
    Wallet and worker %WAL%.%WORKER_NAME%
    Pool URL stratum+tcp://c64.suprnova.cc:6464
    Password x
  • Step 3: Apply and Start
    1. Save the flight sheet and apply it to your worker(s). 2. The miner will start automatically. Check the Miner log tab to confirm shares are being accepted. 3. Your stats will appear on the Your Stats page within a few minutes. Tip: Use port 6465 for mid-range CPUs or 6466 for high-end CPUs for faster VarDiff convergence.
MMPOS Configuration
  • MMPOS Setup
    MMPOS configuration is similar to HiveOS. Use SRBMiner-Multi, cpuminer-opt-supr, or c64miner. Pool URL: stratum+tcp://c64.suprnova.cc:6464 Wallet: YOUR_WALLET_ADDRESS.%WORKER% Refer to the miner GitHub pages for specific MMPOS configuration examples.
