I have an AMD Zen 3 based mini PC with 2 DDR4 SODIMM slots. Everything I've read says dual rank memory has the best performance in AMD systems. How can I determine the rank of a given SODIMM before buying? I'm trying to get a 16GB (2x8GB) 3200MHz kit.
Crucial will list the rank config, but for some they show it can come in 1x8, 1x16 and 2x8. So no idea what I'll get when buying. However, the oldest production were likely the 2x8 with the newest being the 1x16. My best understanding is that counting the chips on the SODIMM should be a good indicator. A SODIMM with 16 chips should be a 2x8 config. I know only having 8 chips or 4 doesn't guarantee that it's single rank, but makes it possible or perhaps likely.
Even chip count doesn't quite solve this... Finding a vendor who will show a picture of the exact RAM they're going to ship instead of a stock image is proving rather difficult too.
Why is this so hard? It seems like only by buying 32gig SODIMMs (DDR4) are you basically guaranteed to get dual rank memory, but I have no need of those and they're quite expensive...
