Troubleshooting PC Stuttering Issues after Upgrading to Ryzen 5900X

  • Update BIOS, chipset drivers, enable XMP for RAM to fix firmware and software issues causing stutter.
  • Switch to Ryzen High Performance power plan in Windows to prevent power management instability.
  • RMA faulty CPU only after trying all troubleshooting steps involving BIOS, drivers, OS settings.

Experiencing performance stutters on your PC after upgrading to a Ryzen 5900X processor? This post examines potential causes and solutions.


AMD’s Ryzen 5900X is a powerful 12-core, 24-thread CPU based on the Zen 3 architecture. With its high core count and IPC improvements, it offers a major upgrade over previous generation Ryzen CPUs. However, some users have reported performance stuttering in games and applications after installing a 5900X.

Troubleshooting PC Stuttering Issues after Upgrading to Ryzen 5900X

Symptoms of the Problem

Common symptoms include:

  • Short intermittent freezes and stutters during gaming or other GPU/CPU intensive tasks
    Sporadic mouse lag and reduced FPS
  • Stutters happen even at low CPU usage
  • Mostly affects single-threaded workloads

Potential Causes

There are a few factors that can contribute to stuttering on the 5900X:

  • Firmware Issues: Early batches of 5900X had firmware bugs causing boost and stability problems.
  • Windows Power Plans: Ryzen performance is sensitive to Windows power plans. The default Balanced plan can cause stuttering.
  • Chipset Drivers: Outdated or buggy chipset drivers can affect Ryzen CPU stability.
  • RAM Configuration: Running RAM at JEDEC speeds instead of XMP profile can impact performance.

Solutions and Troubleshooting Steps

Here are some things to try to resolve 5900X stuttering:

  • Update BIOS to latest version for your motherboard to get firmware improvements.
  • Switch to the Ryzen High Performance power plan in Windows. Avoid Balanced plan.
  • Install latest AM4 chipset drivers from AMD’s website.
  • Enable DOCP/XMP in BIOS to run RAM at full rated speeds.
  • Disable PBO, CPPC and CPPC Preferred Cores in BIOS as they may be unstable.
  • Check temperatures during workloads. Thermal throttling can reduce clocks and cause stutter.
  • Try a manual OC if stutters happen at stock clocks. Test OC stability.
  • As a last resort, RMA the CPU if above steps don’t fix the issue.


With the right firmware, drivers, OS settings and cooling, the 5900X can deliver smooth performance in games and applications. Follow the troubleshooting steps outlined to resolve any stuttering issues after upgrading to this powerful Ryzen CPU. Pay close attention to BIOS settings, RAM configuration and Windows power plans.

Frequently Asked Questions (FAQs)

Question: Will a BIOS update completely fix the stuttering issue?

Answer: For early production 5900X CPUs, a BIOS update usually resolves firmware-related stutters. Update to the latest BIOS from motherboard manufacturer.

Question: Can RAM speed changes remove stuttering?

Answer: Yes, running RAM below its XMP rated speed can cause performance issues. Enable XMP in BIOS to run RAM at its full speed.

Question: Is the Ryzen 5900X defective if I still get stutters after troubleshooting?

Answer: Not necessarily. Try all software fixes before concluding its a hardware defect. RMA the chip only if issues persist after updating firmware, drivers, RAM speed etc.

Question: Will a clean Windows reinstall help resolve 5900X stutter?

Answer: Maybe. A clean OS install can eliminate any driver conflicts. Try less invasive fixes first before reinstalling Windows.
