How to Fix Coil Whine and Audio Stuttering on RX 6750 GRE

Coil Whine and Audio Stuttering Issues with RX 6750 GRE 12GB

Coil whine and audio stuttering issues with the RX 6750 GRE 12GB are typically related to design features of the graphics card and can be partially resolved through a combination of driver settings, FPS limiting, and power component verification. Main solutions include limiting frame rate, lowering GPU voltage, using separate power cables, and replacing display connection cables.

Causes of the Problem

Coil whine and audio stuttering on the RX 6750 GRE often occur due to design features of the graphics card and interaction with system components. As noted by users on forums, these issues may be related.

Main causes:

• High switching frequency of the graphics card’s power components
• Insufficient stability of power supply from the power supply unit
• Driver issues, especially in recent versions
• Conflicts between integrated and discrete graphics in a system with 5600G

According to reports on r/AMDHelp, some users note that the issue may appear even under minimal load, as in your case with cursor animation.

Coil Whine Solution

FPS Limiting

The most effective way to reduce coil whine is to limit the frame rate:

• Set a limit of 60-120 FPS in game settings
• Use programs like RTSS (RivaTuner Statistics Server)
• In AMD driver settings, you can set a global FPS limit

Important: When using a 5600G processor with integrated graphics, make sure the discrete card is used by default in games and applications.

Undervolting

Using MSI Afterburner:

1. Decrease the voltage value by 50-100 mV
2. Check stability in a stress test
3. Find the optimal balance between temperature and noise

As noted by a user on r/buildapc, undervolting can significantly reduce coil drone.

Using Separate Power Cables

Make sure the graphics card is powered by separate power supply cables, not from one connector with an adapter. This improves power supply stability.

Audio Stuttering Fix

Display Connection Check

Many users report that replacing the DisplayPort cable with HDMI resolves audio stuttering issues. As described in r/AMDHelp, simply replacing the cable can completely solve the problem.

BIOS Settings

1. Make sure XMP/DOGE is enabled for RAM
2. Check AMD Smart Access Memory (SAM) settings
3. Disable unnecessary peripheral devices in BIOS

Driver Updates

Sometimes driver issues cause both effects:

• Use DDU (Display Driver Uninstaller) for a complete cleanup
• Install a stable driver version (not the newest)
• Try rolling back to an earlier version, as recommended in r/AMDHelp

Additional Methods

Power Supply Check

Although you have a 1000W 80 Plus Gold power supply, the problem may be in quality or aging capacitors:

• Check +12V voltages in an application like HWMonitor
• Make sure cables are not bent and have good contact
• If possible, test with a different power supply

Graphics Card Repositioning

• Try installing the graphics card in a different PCIe slot
• Make sure it’s firmly seated in the slot
• Check for dust and dirt on contacts

Software Settings

• Disable power saving features in Windows
• Install the latest Windows 11 updates
• Check Windows sound settings for conflicts

When to Contact Support

If the problem persists after all attempts, consider contacting the graphics card manufacturer’s support. As noted by users on Tom’s Hardware, sometimes the only solution is to replace the graphics card.

Signs indicating the need for replacement:

• The problem occurs even under minimal load
• The noise is very loud and annoying
• Audio stuttering interferes with normal PC use
• All software methods are ineffective

Conclusion

Based on the experience of other users with RX 6750 GRE and 6750 XT, the following conclusions can be drawn:

1. Coil whine is a design feature, but it can be minimized through FPS limiting and undervolting
2. Audio stuttering is most often related to driver issues or display connection cables
3. Relationship between problems is confirmed by the fact that solutions for one often help with the other
4. Sequential approach - start with simple methods (cable replacement, FPS limit) and move to more complex ones
5. Patience - some problems may require time to find the optimal solution

I recommend starting with replacing the DisplayPort cable with HDMI and setting a 60 FPS limit, as these methods have given positive results to most users with similar problems.
