So I bought these Teamgroup 16gb sticks used a couple months ago, with the model# FLBD516G6000HC30BK on each stick (no original box). They have a manufactured date of 08/25, and EXPO profile of 6000 30-36-36-76-112. This is my first time on DDR5 so I did a ton of research, and as far as I could tell Teamgroup doesn't tell you anything by model numbers but they were most likely A-die, something I mainly concluded due to the stable tRFC I've achieved (125ns whereas people usually say M-die has to be higher to even POST). They also run at 8000mt/s but I think I need better cooling before I seriously attempt that as my daily setup.
With all that known these are the stable timings I've landed on– *however*, in quickly trying to find some info on a 2x8gb 6000cl38 kit I ordered for my living room PC, I noticed Gigabyte's QVL page lists die types (supposedly the cl38 kit is A-die). Now, neither their QVL nor my X870E-E's QVL lists the model number that was actually on my sticks, but the closest model on Gigabyte's site just ends in 01 instead of BK with the exact same timings and voltage, but it's listed as M-die.
This doesn't really matter to my OC anymore since I've already tuned everything as tight as I can go with the voltage and temps I was targeting, but I'm still curious now… does 16gb M-die actually go this low on tRFC, or is Gigabyte just confused? Or am I assuming too much that the last 2 digits of the model wouldn't actually mean completely different sticks?
