Ryzen Tuned RAM

Finally getting back in the PC gaming world after many years away. I'm building a new Ryzen B550 based system and looking at RAM.

Scan sell 2 versions of the 2x8GB LPX Black 16GB 3600 MHz DDR4 kit.

They appear to be identical, both 3600Mhz, 18-22-22-42. The only difference I can see is that one is "Ryzen Tuned" with a higher price.

Any ideas if this is just marketing or is there actually a technical difference?

just marketing, i went with crucial billistix 3600 cl 16 much better value

Seems odd... Would have expected a change in CAS / CL or speed, but nope. Feels like a marketing thing
