AMD Radeon RX 6000 Series Main Issues

🔧 1. Unstable memory (VRAM)

Symptoms: artifacts, game crashes, freezes.

Causes:

Video memory overheating (especially in models with GDDR6 and weak cooling).

Incorrect VRAM frequencies in BIOS.

Especially affects: RX 6800 XT, RX 6900 XT with factory overclocking.

 

🌡️ 2. High Hot Spot temperature

Symptoms: core temperature is normal, but Hot Spot can reach 100–110°C.

Causes:

Uneven contact between the chip and the radiator.

Bad thermal pads on the memory/VRM.

Solution: replace the thermal interface, grind the cooler base.

 

⚠️ 3. Driver failures and black screen

Especially at the start of sales (2020–2021).

Symptoms: black screen when loading Windows or when idle, driver crashes.

Causes:

Conflict with Windows 10/11.

Unstable versions of Adrenalin.

Solution: install a stable driver version (usually 22.5.1 LTS), disable Hardware Acceleration in browsers.

 

🔌 4. Coil Whine (coil squeak)

Symptoms: high-pitched squeak under high load (in games/benchmarks).

Causes:

Design features of VRM on individual models.

Lack of proper noise reduction or resin.

More pronounced in: PowerColor, ASRock, some MSI.

 

📉 5. Performance drop (low FPS)

Symptoms: FPS below expected level, stuttering.

Causes:

Poor driver optimization for DX11/OpenGL.

Smart Access Memory is not enabled.

Incorrect BIOS/UEFI settings or PCIe is running in x8/x4 mode.

Solution: update motherboard BIOS, enable Re-Size BAR.

 

🧰 6. Defective/weak cooling in certain brands

Weak cooling: ASUS Dual, XFX QICK, Gigabyte Eagle.

Reliable models: Sapphire Nitro+, PowerColor Red Devil, ASUS TUF.

 

✅ How to minimize problems:

  • Update the video card BIOS to the latest (if available).
  • Use Adrenalin drivers not lower than version 22.5.1.
  • Check temperature readings via HWiNFO64.
  • Clean cooling regularly, change thermal pads.
  • Install the card in a case with good ventilation.
