Hello @IMRANSYF11
We apologize for the delayed response.
Regarding the ECC memory specifications for the PRIME B650M-A, we are still in the process of confirming with the relevant team.
May I ask if you are currently using this model, or are you planning to purchase it?
If you are already using it, could you please confirm the model and part number of the installed memory?
Additionally, since the serial number involves personal data, I have DM you to confirm.
Kindly check the inbox on the top-right corner at your convenience.
Thank you.
