Steps to Optimize Antminer S19 for Bitcoin Mining

Optimizing Antminer S19 for mining cryptocurrencies can be a complex task, but with the right approach, you can increase your mining profitability significantly. Here are some steps you can follow.

Pool Selection

The first step in optimizing Antminer S19 is to select a mining pool that suits your needs. 

There are many variables to look at before choosing a Bitcoin mining pool for S19 ASIC miner. Task assignment methods, reward distributions, total hashrate, hardware and software compatibility are only some examples.

Each of these factors will impact your mining revenue and profitability.

Hardware and Software Compatibility

some pools may not be accessible if not through specific mining software. They occasionally might even need a specially created program of their own to run.

Compatibility for your mining setup should be the first thing to consider, as no other feature or characteristic will be relevant if that pool doesn’t support your equipment.

Mining Pool Payment System

Not all pools compensate their miners for the same tasks or durations. Different systems are used by pool operators to compute, distribute, and carry out payments.

Some of the most commonly used are:

Proportional Payments

Payments are calculated based on a division into rounds, where a round is a time between one block found by the pool to the next.

At the end of every round, when the pool finds a block and receives the reward, the operator keeps a fee and payments are distributed among the miners in direct proportion to the number of shares they submitted during this round.


When a participant submits a share, they are immediately rewarded correspondingly to the expected value of this share’s contribution, minus fees — it doesn’t matter if the pool finds a block or not.

The operator gets to keep all the rewards for solved blocks. Consequently, the price per share is a predetermined, deterministic value.

Pay Per Last N Shares (PPLNS)

Similar to proportional, but instead of paying per round, pool operators define a specific period of time (N). For the shares submitted within the predetermined time, miners receive rewards.

Additionally, some Bitcoin mining pools may establish a minimum threshold miners have to reach before collecting payments. For miners with low output, this is particularly crucial because it might take them longer to reach that level.

On the other hand, operators may also set a cap for how much each miner can withdraw from the pool for given time periods.

Again, consider your setup and your computing power to decide which payment system suits you best.

Task Assignment Methods

A mining pool’s methods for allocating work to its miners and calculating their share earnings vary.

Some Bitcoin mining pools allow total freedom to individual miners to choose difficulty targets and work ranges. This enables them to work as much as they want without requiring job assignments from the pool.

Other pools assign work units — specific nonce ranges — to miners according to their relative hashrate. The most capable miners might be given more work while their less capable counterparts might be given fewer tasks.

Naturally, the pool modifies its payouts accordingly. In order to maximize output and performance and maximize revenue for each miner, operators take such measures.

Mining Pool Size and Total Hashrate

The size of the pool is another factor that might have an impact on your mining earnings, even though it typically remains roughly constant proportionally over time.

Large pools have better odds of breaking blocks. However, as they have to distribute rewards among more miners, these are often lower.

On the contrary, small pools offer higher profits when solving a block, but this happens less regularly.

It comes down to what you prefer the most: a high probability of lower rewards or a low probability of higher revenue.

Mining Pool Transparency and Fees

Each mining pool has its operator — the entity or organization that manages it, chooses the task assignment method, the reward payment system, etc.

Individual miners who connect to pools can look at different mining pools’ data to ensure that the operators are honest and distributing rewards fairly.

To achieve greater transparency, some mining pools make this information available to everyone online and in real-time.

Each Bitcoin mining pool uses a unique business model, on a similar level. Some pools charge a participation fee, calculated based on various formulas.

Other pools have no participation fees but may have additional costs, like entry commissions, the requirement to purchase specific mining software, or keeping the transaction fees and distributing only block rewards.

Be sure to evaluate these factors and see that the pool operators are well-intended, provide transparent information about pool performance and fee calculations, and generally act fairly.

Firmware Updates

How to Optimize Antminer S19 for Bitcoin Mining

Overclocking your Antminer S19 can increase its hash rate, which translates into higher mining profitability. However, overclocking also increases power consumption and heat generation, so it should be done carefully. You can start by increasing the frequency by small increments and monitoring the Antminer temperature and stability of the device.

Cooling System Optimization
