How to fix "FAILED TO APPLY MSR MOD HASHRATE WILL BE LOW" error

29 de Agosto de 2024 às 15:57

MSR MOD (Model-Specific Registers) is a useful feature that boosts RandomX performance by 10-30%. To enable MSR MOD, the miner utilizes a particular driver called WinRing0x64.sys.

The error FAILED TO APPLY MSR MOD HASHRATE WILL BE LOW occurs when the miner cannot locate the WinRing0x64.sys driver or lacks administrator rights to apply MSR MOD.

In this article, we will guide you through how to resolve this issue.

Step One — Check Your Antivirus

Many viruses silently mine cryptocurrency without the user's permission. That is why most antivirus programs block miners by default. Windows Defender has this aggressive security policy, too.

Before downloading and running the miner, temporarily pause your antivirus to prevent it from deleting the xmrig.exe file and the WinRing0x64.sys driver. If the antivirus does delete them, be sure to add these files to the antivirus exclusion list.

If you're mining with the Kryptex application, ensure your antivirus hasn't compromised any Kryptex files. Add Kryptex files to your antivirus exception list.

Step Two — Give the Miner Administrator Rights

If you're running the XMRig miner using a batch file instead of the Kryptex app, make sure to grant permanent administrator rights to the xmrig.exe file. The batch file itself should be run without administrator rights.

If you are mining with the Kryptex app, you can skip this step — Kryptex has already taken care of it for you 👍

  1. Right Mouse Click xmrig.exe file
  2. Choose “Properties
  3. Choose “Compatibility” tab
  4. Tick “Run this program as an administrator
  5. Press “Apply” and “OK

    Next, run the miner using the batch file. If the error is resolved, great—enjoy your mining 🤗

If the error persists, reboot your PC to ensure the WinRing0x64.sys and MSR MOD drivers are properly registered in Windows. After the reboot, the error should be gone.

Additional information

If the previous tips didn’t fully resolve your issue, here are a few more suggestions:

  • For Windows 11 users — disable Core Isolation.
  • Turn off virtualization, which is a technology that allows multiple operating systems to run simultaneously. This can be done in your motherboard’s BIOS. Depending on the manufacturer, it might be labeled as VTx, Intel Virtualization Technology, Intel VTT, Hyper-V, or AMT VTT.
  • If you also see the error WinRing0_1_2_0 already exists when starting the miner, it means that the MSR cache is full, busy with another background process or service. How to fix the WinRing error, described in this article.
