I was going to say unless it is a several year old RAM set, but the date says May 2020 on it. Also looks like a quad channel (4x8GB) kit? I would think it was some sort of Hynix memory based on the timings. That's not a bad thing (unless you paid for B-die). Hynix works just fine for the most part.Thanks for the pic and the newest version of Thaiphoon shows this has B die?
The timings would be the first thing I see on them that would tell me they were not B die.
