Optimizing your mining hardware is crucial for achieving maximum efficiency, especially when working with older but still capable GPUs. This guide focuses on enhancing the Ethereum mining performance of NVIDIA's GeForce GTX 1080 and 1080 Ti graphics cards, which utilize GDDR5X memory. With the right adjustments, these GPUs can reach impressive hashrates exceeding 50 MH/s.
Understanding the Optimization Tool
The optimization tool discussed here is specifically designed for NVIDIA GPUs equipped with GDDR5X memory. By fine-tuning the memory operation, it allows these cards to perform at a significantly higher level during Ethereum mining. Currently, the primary beneficiaries of this optimization are the GeForce GTX 1080 and 1080 Ti models.
How the Optimization Works
This tool works by adjusting the memory timings on the GDDR5X VRAM, allowing for faster data access and processing. This is particularly effective for the Ethash algorithm used in Ethereum mining, which is memory-intensive. The result is a notable increase in hashrate without a corresponding increase in power consumption, improving overall mining efficiency.
Step-by-Step Installation Guide
To apply this optimization to your mining setup, follow these straightforward steps.
- Extract the Files: Locate the downloaded package. If you are on Windows, it will be a .zip file. On Linux, it will be a .gz archive. Use appropriate software to extract the contents to a folder of your choice.
- Run the Application: Find the executable file named
OhGodAnETHlargementPill. On a Windows system, right-click the file and select "Run as administrator." On a Linux system, run the command with root privileges (e.g., usingsudo). - Monitor Performance: After launching the tool, closely observe your mining software's reported hashrate. You should see a significant increase, confirming the optimization is active.

Troubleshooting Common Issues
Sometimes, the tool might not work as expected. A common reason is an older memory revision on your GPU.
Using the revA Parameter
The tool includes a command-line parameter, --revA, which allows you to specify which GPUs in your rig should receive the optimization. This is useful if some of your cards have a different memory type or are not responding.
For example, if GPUs 0, 3, and 4 in your system are not the expected models, you can target them specifically using one of these commands:
- Windows Command Prompt:
OhGodAnETHlargementPill.exe --revA 0,3,4 - Windows PowerShell:
.\OhGodAnETHlargementPill.exe --revA 0,3,4 - Linux Terminal:
./OhGodAnETHlargementPill --revA 0,3,4
Ensuring Continuous Operation
For the hashrate improvement to persist, the optimization tool must remain running in the background. Do not close the terminal or command window after executing the command. It needs to stay active for the duration of your mining session.
Maximizing Your Mining Efficiency
Beyond just applying a patch, sustainable mining involves a holistic approach to your operation.
Optimal Mining Rig Configuration
Ensure your overall system is configured for stability. This includes using a reliable power supply, maintaining adequate cooling for your GPUs, and using a mining-focused operating system or a stable version of Windows or Linux. Driver updates can also impact performance, so it's often best to use versions known for stable mining.
Monitoring and Maintenance
Regularly monitor your rig's performance, temperatures, and power draw. Software like HWiNFO64 or GPU-Z can provide detailed insights. Keeping your hardware clean and well-cooled will ensure it continues to perform optimally over the long term.

Frequently Asked Questions
What is the main function of this optimization tool?
This tool modifies the memory timings on NVIDIA GPUs with GDDR5X memory, specifically the GTX 1080 and 1080 Ti. This allows the cards to process the Ethash mining algorithm more efficiently, leading to a substantial increase in Ethereum hashrate.
Is it safe to run this tool on my graphics card?
When used as directed, the tool is generally considered safe by the mining community. However, any software that modifies hardware settings carries some inherent risk. Always ensure your GPUs are properly cooled and monitor them closely after applying any optimization.
Why do I need to use the --revA parameter?
The --revA parameter is a troubleshooting command for targeting specific GPUs in a multi-GPU rig. It is primarily useful for older memory revisions that may not respond to the standard optimization command, allowing you to apply the patch to them individually.
Do I need to run this tool every time I start my computer?
Yes, the optimization is not permanent. You will need to execute the tool each time you reboot your mining rig or start a new mining session. For convenience, you can add the command to your system's startup scripts.
Will this tool work for mining cryptocurrencies other than Ethereum?
No, this patch is specifically tuned for the Ethash algorithm used by Ethereum and Ethereum Classic. It will not provide a hashrate boost for other algorithms like KawPow (Ravencoin) or Octopus (Conflux).
Can I use this on other NVIDIA GPUs like the 1060 or 2070?
No, this tool is exclusively designed for the memory architecture of the GDDR5X VRAM found in the GTX 1080 and 1080 Ti. It will not work on cards with standard GDDR5 or GDDR6 memory.
