Notes: 1. All serial PD data are not protected. 0: Serial data, “driven Low”, 1: Serial data, “driven High”
These SPD are based on Rev. 1.2B Specification.
2. Byte72 is manufacturing location code. (ex: In case of Japan, byte72 is 4AH. 4AH shows “J” on
ASCII code.)
3. Bytes 95 through 98 are assembly serial number.
4. All bits of 99 through 125 are not defined (“1” or “0”).
