Yes. You can connect more than one physical miner to a single Mining Rig Rentals rig.

This is useful when you want several ASICs, GPU rigs, or miner instances to work together as one rentable rig. The combined hashrate from all connected miners becomes the hashrate available through that rig listing.

For larger farms or very high miner counts, see Listing a Large Mining Farm.

When should I connect multiple miners to one rig?

Connecting multiple miners to one rig works well when the miners are intended to operate as one group.

Common examples include:

• several ASICs of the same model,
• multiple GPU rigs mining the same algorithm,
• miners located in the same rack or room,
• miners managed as one operational group,
• miners you want rented together as one hashrate package.

This setup is usually easier for renters because they rent one rig instead of several smaller listings.

Requirements

All miners connected to the same MRR rig should:

• mine the same algorithm,
• use the same MRR rig connection information,
• be stable under normal operation,
• submit accepted shares,
• have low rejected and stale shares,
• stay connected during rentals,
• be included in the rig’s advertised hashrate.

Do not connect miners for different algorithms to the same rig listing.

How to connect another miner

To add another physical miner to an existing rig:

1. Open the rig’s connection information in Mining Rig Rentals.
2. Copy the pool/server, port, worker, and password information.
3. Enter the same connection details into the additional miner.
4. Save the miner configuration.
5. Restart or reload the miner if required.
6. Check the Workers tab for the new connection.
7. Confirm the miner is submitting accepted shares.

The new miner should appear as another worker or connection under the rig.

Identifying each miner

Use a clear password identifier if your miner supports it. You can connect to the Mining Rig Rentals with a password identifier.

This can help you identify individual miners in the Workers tab.

For example, you may want worker names or identifiers that match:

• ASIC serial number,
• rack location,
• shelf position,
• miner number,
• hostname,
• management system name.

Clear naming makes troubleshooting much easier when one miner disconnects, submits rejected shares, or produces lower hashrate than expected.

Check the Workers tab

After connecting more than one miner, review the Workers tab.

Confirm that each miner:

Do not assume the rig is healthy just because one miner is working. Check every connected miner.

Set the advertised hashrate correctly

When multiple miners are connected to one rig, the advertised hashrate should represent the combined stable hashrate of all miners in that rig.

For example, if you connect five miners that each reliably produce 100 TH/s, the combined rig may be advertised around 500 TH/s, assuming all five miners remain stable and accepted shares confirm that performance.

Do not advertise the theoretical maximum hashrate if the miners cannot reliably deliver it through Mining Rig Rentals.

If one miner is unstable or frequently offline, remove it from the rig or lower the advertised hashrate.

Keep similar miners together when possible

For best results, group similar miners together.

Good grouping examples:

• same ASIC model,
• same firmware,
• same algorithm,
• same hashrate range,
• same physical location,
• same network path,
• same power and cooling environment.

Mixing very different miners can make hashrate reporting and troubleshooting harder.

If one miner behaves differently from the rest, consider listing it separately.

Do not hide unstable miners in a group

Do not add unstable miners to a larger rig just to increase the displayed hashrate.

A grouped rig is only as reliable as the miners behind it. One unstable miner can cause:

• lower delivered hashrate,
• more rejected shares,
• more stale shares,
• worker disconnects,
• renter complaints,
• refund reviews.

Fix unstable miners before including them in a rentable rig.

How many miners should I connect to one rig?

For small and medium setups, connecting multiple miners to one rig is normal.

However, bigger is not always better. A very large single rig can be harder to manage, harder to troubleshoot, and more disruptive if something goes wrong.

As the number of connected miners grows, consider splitting them into multiple MRR rigs based on:

• rack,
• location,
• ASIC model,
• hashrate size,
• power circuit,
• network switch,
• stability,
• maintenance group.

This keeps each rig easier to monitor and reduces the impact of a single failure.

For large farms or hundreds of miners, use the guidance in Listing a Large Mining Farm.

When to create another rig instead

Create a separate MRR rig when:

• miners are on a different algorithm,
• miners are in a different location,
• miners have very different performance,
• some miners are less stable than others,
• you want separate pricing,
• you want separate rental availability,
• you want easier troubleshooting,
• the worker list is becoming difficult to manage,
• the group is large enough that failures are hard to isolate.

Multiple smaller rigs are often better than one oversized rig.

Common problems

New miner does not appear in the Workers tab

Possible causes:

• wrong server or port,
• wrong worker name,
• wrong password,
• miner does not support the connection method,
• network or firewall issue,
• ASIC firmware issue,
• miner is connected to an old endpoint.

Check the miner’s pool configuration and logs. If the miner does not support normal reconnect behavior, use the assigned or direct rig port shown in the rig connection information.

New miner appears but has no accepted shares

Possible causes:

• wrong algorithm,
• incorrect pool settings,
• wrong firmware mode,
• miner is not receiving valid work,
• pool difficulty issue,
• hardware problem.

Connection status alone is not enough. Confirm accepted shares.

One miner has many rejected shares

Possible causes:

• unstable hardware,
• overheating,
• bad hashboard or GPU,
• aggressive overclock,
• wrong miner settings,
• firmware issue.

Remove or repair the miner before including it in the advertised hashrate.

Total hashrate is lower than expected

Possible causes:

• one or more miners offline,
• miners not submitting accepted shares,
• high rejected or stale shares,
• advertised hashrate set too high,
• pool difficulty causing short-term reporting swings,
• thermal throttling,
• power or network instability.

Check each worker individually rather than only looking at total rig hashrate.

When to read the large farm guide

Use Listing a Large Mining Farm if:

• you are connecting a large number of miners,
• you are managing hundreds of devices,
• you are approaching connection limits,
• you need to split miners across multiple servers,
• you want a private or dedicated rig server,
• you are unsure how to group a large farm,
• reconnect behavior becomes difficult to manage,
• worker visibility becomes too crowded.

This article is intended for ordinary multi-miner rig setups. Large farms require more planning.

Summary

You can connect more than one physical miner to a single Mining Rig Rentals rig.

Make sure all miners use the same algorithm, connect with the correct rig information, submit accepted shares, and are included honestly in the advertised hashrate.

For small and medium groups, this is normal. For large farms, split miners into manageable rig groups and follow the Listing a Large Mining Farm guidance.
