This 8GB RAM is 100% compatible with the Gigabyte AORUS PRO AX X570SI (rev. 1.0). Information regarding memory configuration: The following technical specifications should be considered in advance: Non-ECC or ECC (Error-Correction-Code) RAM can be installed in the device. Modules labeled ECC have error correction capabilities. Non-ECC memory modules cannot be mixed with ECC memory. If a memory upgrade is to be made with the existing RAM, it must be checked which memory technology (non-ECC / ECC) is present. A higher memory clock speed of the memory module will automatically adjust to the clock speed set by the system. This is especially true for larger capacities.
