Chip marking on M34E04B SPD eeprom : EBTF vs. EETF. What is the Difference?

[HRuck.1]

Hello,

I have a PC system with specific issues to boot with some SO-DIMMs. one of the diffrence between working and non working SO-DIMMs is the Marking on the SPD Chip.

One has EBTF one BBTF marking. Based on internet searches I think to know, that at least EBTF is a M34E04B SPD EEPROM.

So far I have not found the decoding what means EBTF vs. BBTF.

Does anybody know how ti figure out the difference ?
