Title: Beware of the single rank x16 RAM kits sneaked in some laptop models! The 1Rx16 modules have significantly lower bandwidth compared to the 1Rx8 variants

The more bank groups a memory module has, the higher the bandwidth is. Contrary to what the naming convention may suggest, the single rank x8 modules have twice as many bank groups compared to the single rank x16 variants. Laptop OEMs unfortunately never reveal the ranking information.

You should probably link Jarrodtech since he was the originally the one that discovered this memory issue in the first place not to mention he goes into greater details about this

I linked an article that features one of his videos in the second paragraph. I already covered his videos in two previous articles.

Will you provide this data in your future laptop reviews?

This is long known so I think you did fine by quoting jarrod for it bringing to your attention . If you look at the 1usmus stuff you can see that ryzen 3000 has long been sensitive to what rank you buy. Its also always been know to get 4 single rank sticks or 2 dual rank sticks to achieve highest bandwidth so jarrod just rediscovered old info tbh
