Since AMD’s auto‑detector no longer supports K15, manual installation is required:
Verification commands (admin PowerShell):
Get-WmiObject Win32_PnPSignedDriver | Where-Object $_.DeviceName -like "*AMD*Memory*"
Get-WmiObject -Class Win32_PerfFormattedData_AMD_PMC_Counter
Expected output: DeviceName AMD Memory Controller, Status OK.
Cause: Each core complex (CCX) on dual-socket Opteron systems gets a separate device node.
Fix: This is normal for server boards. Do not disable either.
| Question | Answer | |----------|--------| | Is “AMD K15 IMC” a virus? | No – it’s a real hardware component. | | Do I need a separate driver? | No – use the full AMD chipset package. | | Can I ignore the yellow bang? | Yes – especially on Windows 10/11. | | Will it affect gaming? | Not at all. |
If you’re still running a Phenom, FX, or A-series APU in 2025, kudos to you. That K15 memory controller has been chugging along for over a decade. Give it a pat on the back (or a fresh tube of thermal paste) and stop worrying about the driver.

Disclaimer: This post is for legacy hardware. AMD officially ended support for Family 15h in chipset drivers after version 19.10. Use at your own risk.
The AMD K15 IMC (Integrated Memory Controller) is a component of AMD's 15h family of processors (such as Bulldozer, Piledriver, Steamroller, and Excavator architectures). Drivers for these components are typically bundled within broader AMD Chipset Driver packages rather than offered as standalone "K15 IMC" downloads. Where to Find the Drivers
You can find the compatible chipset drivers through official manufacturer support pages:
AMD Official Support: Use the AMD Drivers and Support page. You can use their "Auto-Detect and Install" tool or manually select your chipset series (e.g., 9-Series, 7-Series, or specific socket types like AM3+ or FM2+) to get the correct package.
Manufacturer Support: If you are using a pre-built system or laptop, brands like Lenovo and HP provide specific chipset drivers validated for models like the ThinkCentre, IdeaCentre, or Pavillion series. What the Drivers Include
When you install an AMD Chipset package for K15-era hardware, it typically installs several critical sub-drivers: Since AMD’s auto‑detector no longer supports K15, manual
SMBus Driver: Enables communication with the System Management Bus for hardware monitoring (temperature sensors, fan speeds).
GPIO Driver: Manages General Purpose Input/Output signals for motherboard features.
PCI Device Driver: Ensures the operating system correctly identifies and communicates with PCI expansion slots.
Processor Power Management: Optimizes power plans and CPU boost behavior for better efficiency and stability. Why They Are Necessary
System Stability: Installing these drivers can resolve issues like random Blue Screen of Death (BSOD) errors or system crashes (e.g., Kernel 41 errors).
Performance: While Windows may install generic "default" drivers, the official AMD versions often provide better CPU performance and more reliable overclocks. Expected output: DeviceName AMD Memory Controller , Status
Hardware Recognition: Without these, specific hardware components like the integrated memory controller or USB 3.0/3.1 ports might not be recognized correctly by the OS.

AMD K15 IMC Chipset Drivers: A Comprehensive Guide If you've encountered "AMD K15 IMC" while using diagnostic tools like CPU-Z or checking your device manager, you're likely working with a system powered by an AMD processor from the Family 15h architecture. The K15 IMC (Integrated Memory Controller) is a critical sub-component of these processors, and ensuring its drivers are correctly installed is vital for system stability. What is the AMD K15 IMC?
The AMD K15 IMC refers to the Integrated Memory Controller within the AMD Family 15h processor series. This architecture includes several well-known processor lines: AMD FX Series (e.g., FX-8350)
AMD A-Series APUs (e.g., Trinity, Richland, Kaveri, and Carrizo) Athlon and Sempron variants using these cores
The IMC acts as the high-speed bridge between your CPU and system RAM. In older diagnostic readouts, it is often listed as a "Northbridge" component because it handles the critical data traffic that was once managed by a separate chip on the motherboard. Why You Need These Chipset Drivers
Chipset drivers act as the "instruction manual" for your operating system (OS), telling it exactly how to communicate with the hardware on your motherboard.
