Warning #104

MSI is not enabled. Read how to enable it here. Message Signaled Interrupts is a method of CPU-GPU communication. Wiki states that:

When activating MSI, you can actually notice that your GPU will is more stable. Especially if your GPU crashes here and there due to high OC values, the crash will be easily recoverable without PC restart and other GPUs will not be so drastically affected. Without MSI enabled, a crash of a single GPU usually results in a blue screen of the entire OS thus reboot of the PC

Notice: Enabling MSI might cause issues with LHR unlock.

Error #105

This error means that QuickMiner cannot communicate with Excavator. Potential solutions:

• Reinstalling the GPU drivers. Try different versions. It is confirmed that NVIDIA drivers before 511.xx were causing the issues. Follow this guide to correctly reinstall the GPU drivers.
• Make sure nothing is blocking QuickMiner or Excavator. It is known that some antivirus software recognizes QuickMiner or some of its components as a false positive. Read how to whitelist QuickMiner in Windows Defender here. 
• Check if any other program is using port 18000. This is what Excavator uses to communicate with QuickMiner. Open the QuickMiner config file (nhqm.conf) and change this setting: "watchDogAPIPort" : 18000 to some other port like 18032 for example.
• Reinstalling QuickMiner.
