Bypassing GPU lock (such as RTX 20xx GPU) when installing ChatRTX from Nvidia

readme.md

By time time of writting which is 11th Aug 2024, ChatRTX from Nvidia has only offically supported RTX 30/40 series GPU. I have a RTX 2080Ti which Nvidia has abandoned support.

I don't like this.

So I found out the way of bypassing the ChatRTX installation process on Windows 11 with RTX 2080 Ti.

After finishing downloading all the ChatRTX zip file from Nvidia, find some files in the folder and change it. https://www.nvidia.com/en-us/ai-on-rtx/chatrtx/

Steps

1. remove lines in ChatRTX.nvi

<custom name="GpuSupportCheck" level="error" text="${{IncompatibleGpu}}"/>
<custom name="VRAMSizeSupportCheck" level="error" text="${{IncompatibleVRAMSize}}"/>
<custom name="CheckDriverVersion" level="error" text="${{IncompatibleNVDriverVersion}}"/>

2. remove lines in Setup.cfg

<reject tests="DUPLICATES" level="critical" text="${{ErrorPackageCorrupt}}"/>

3. download Microsoft MPI and install it manually before installing ChatRTX from here https://www.microsoft.com/en-us/download/details.aspx?id=105289

4. click setup.exe to start ChatRTX installation
