256GB all matched and stable at XMP timings, normally workstations used much slower memory at stock timings, like 2666 or 2933.

For many brands the fancy looking stuff is faster/better binned just like you can tell visually when a car is more expensive. There's definitely much more plain memory with good specs like the Ripjaws entry-priced gaming RAM, but some RGB memory can also use their lights to report important status information about your system. For example temperature reporting. This is also why modern memory has a metal sleeve, it's to spread out the heat from the chips. Professional workstations with visual temperature reporting are a godsend, it's very easy to flag a system for cleaning or repasting.
