Introduction: What is an Aptio CRB Motherboard? If you have stumbled upon the term "Aptio CRB" in your system information (often by typing msinfo32 into Windows Run), you might be confused. Unlike an ASUS, Gigabyte, or MSI motherboard, the "Aptio CRB" does not refer to a specific retail brand. Instead, CRB stands for Customer Reference Board , and Aptio refers to the BIOS software developed by American Megatrends International (AMI) .
