RAM is not working properly.
They arrived in a package, making them identical. The versions I’ve used for a while started in 2019, while the latest ones came out in 2023.

It's strange the frequency seems too low.
It seems like there might be a display issue. It appears to be running slower than expected despite your settings.
Maybe, though it would increase the intrigue haha
