How do I set a fixed difficulty on SupportXMR?

To request a fixed difficulty on SupportXMR, add +NUMBER to the end of your Monero wallet address in your miner’s pool username. For example, YOUR_XMR_WALLET_ADDRESS+100000 requests a share difficulty of 100,000; SupportXMR’s current limits still apply.

Put the difficulty in the wallet field

Your miner usually sends your wallet address as its pool username. That tells SupportXMR where to credit your mining work.

Keep your full wallet address unchanged, then add a plus sign and the difficulty number:

YOUR_XMR_WALLET_ADDRESS+100000

Replace the placeholder with your actual address. Do not add spaces, commas, or quotation marks inside the username.

The setting belongs in the wallet or username field, not the worker name or password field. A worker name is simply a label that helps you recognize a particular mining device.

Keep your existing SupportXMR server address, port, and connection security settings unless you have a separate reason to change them.

Example for XMRig

XMRig is a mining program that runs directly on your computer. If you use its configuration file, find the SupportXMR entry inside the pools list and change its user value:

"user": "YOUR_XMR_WALLET_ADDRESS+100000"

This is one line from the configuration, not a complete configuration file. Leave the surrounding settings intact.

If you start XMRig from a command line, the equivalent username option is:

-u YOUR_XMR_WALLET_ADDRESS+100000

Save your change and restart the miner, or reconnect it to the pool. The pool reads this request when your miner connects.

Choose a difficulty your device can handle

A share is a piece of mining work your miner sends to the pool as proof of its contribution. Share difficulty controls how much work, on average, is needed to find one.

Higher difficulty does not make your computer faster or automatically increase your earnings. It means fewer, more demanding shares.

A useful estimate is:

Average seconds per share = difficulty ÷ hashes per second

Your hashrate is the number of mining calculations your device performs each second. For example, at 1,000 hashes per second, difficulty 100,000 gives an average of about 100 seconds per share. Actual gaps vary because mining involves chance.

Treat 100,000 as an example, not a recommended setting for every device. If you have no specific reason to use fixed difficulty, SupportXMR’s automatic adjustment is usually the simpler choice.

Check that SupportXMR accepted it

After reconnecting, check your miner’s messages for the difficulty assigned to new jobs and for accepted shares.

If the assigned difficulty differs from your request:

• Check that the suffix is in the username.
• Confirm you edited the active pool entry.
• Check SupportXMR’s current instructions and permitted difficulty range.

For browser mining, this only works if your browser miner lets you edit the actual SupportXMR login. A website that manages the pool connection for you may not expose that setting.

The bottom line

Use YOUR_XMR_WALLET_ADDRESS+DIFFICULTY as your SupportXMR username, reconnect, and verify the assigned difficulty. Fixed difficulty changes how often you submit shares—not how much computing power you have.
