Limiting CPU performance with a performance limit of

What is POWER-LIMIT-THROTTLE?

The POWER-LIMIT-THROTTLE error is categorized as a medium-severity processor (CPU) issue that can significantly impact your PC's stability. The CPU is running below maximum power due to the PL1/PL2 limits of the motherboard or laptop. When experiencing the Limiting CPU performance with a performance limit of fault, users often report sudden system crashes, unresponsive behavior, or a blue screen of death (BSOD). In most diagnostic scenarios, this problem is directly triggered by underlying hardware or software complications such as low pl1/pl2 limit in bios, laptop thermal policy, weak power source and intel xtu settings. To permanently resolve the POWER-LIMIT-THROTTLE issue and prevent further system degradation, it is highly recommended to follow our step-by-step troubleshooting guide below, ensuring your processor (CPU) components are functioning correctly.

Common Causes

• Low PL1/PL2 limit in BIOS
• Laptop thermal policy
• Weak power source
• Intel XTU settings

Step-by-Step Fix Guide

• 1
  In BIOS, increase PL1 and PL2 limits

  Applying the first fix (In BIOS, increase PL1 and PL2 limits) addresses the most common root cause of POWER-LIMIT-THROTTLE and restores baseline functionality.

• 2
  In XTU, adjust the power limits

  If the problem persists, proceeding with the remaining steps ensures all edge cases related to cpu instability are covered.

• 3
  Check the power settings in Windows
• 4
  Upgrade the cooling
