How to Fix: Undervolted my 9070XT with -100mv, not sure where to go next to extract per

Quick Answer: Next steps: Monitor GPU temperatures and voltages to ensure they're within safe limits, consider using HWiNFO or MSI Afterburner to fine-tune undervolting settings.

The issue you're experiencing, where the GPU is not being utilized to its full potential despite undervolting, can be attributed to various factors. One common cause is insufficient power delivery from the PSU. Although your Corsair RM650x is a Gold-rated PSU, it may still not be sufficient for the 9070 XT's power requirements, especially when overclocked or under heavy loads.

⚠️ Common Causes

  • Insufficient power delivery from the PSU
  • Inadequate cooling or thermal throttling due to GPU temperatures
  • Overclocking or undervolting not optimized for the specific GPU model

🛠️ Step-by-Step Verified Fixes

Method 1: Power Delivery Upgrade

  1. Step 1: Replace the Corsair RM650x with a higher-wattage PSU, such as the Corsair RM750 or RM850, to ensure sufficient power delivery for the 9070 XT.
  2. Step 2: Monitor GPU temperatures and adjust cooling settings accordingly to prevent thermal throttling.
  3. Step 3: Re-undervolt the GPU using Adrenalin or another software, ensuring that the voltage is optimized for the specific model and your system's configuration.

Method 2: Cooling Optimization

  1. Step 1: Install additional cooling solutions, such as a custom watercooling loop or high-performance air coolers, to improve GPU temperatures and prevent thermal throttling.
  2. Step 2: Adjust your system's power settings to prioritize the GPU during heavy loads, ensuring that it receives sufficient power and cooling resources.

Method 3: GPU Model-Specific Optimization

  1. Step 1: Consult the official documentation and forums for the Sapphire Pulse 9070 XT to determine optimal undervolt settings, power delivery requirements, and cooling configurations.
  2. Step 2: Use specialized software or tools, such as MSI Afterburner or EVGA Precision X3, to fine-tune your GPU's performance and optimize its power consumption.

💡 Conclusion

By addressing the potential causes of your issue, you should be able to extract better performance from your Sapphire Pulse 9070 XT. Remember to monitor your system's temperatures and power consumption closely during these adjustments to avoid any potential damage or stability issues.
