Is DDR register required when replacing memory and CPU

[mengxueyue]

Hello:

Do I need DDR register programming help when replacing memory and CPU?

Is it necessary to use only the DDR stress tool？

Thanks have a great day!

Hi @mengxueyue 

DDR RPA (or simply RPA) is an Excel spreadsheet tool used to develop DDR initialization for a user’s specific DDR configuration (DDR device type, density, etc.). The RPA generates the DDR initialization script for use with the DDR Stress Test tool.

So, it depends on whether the type, density or pin map of the replaced ddr have changed。

Best regards
