Edit: this is also why some “extreme overclocking”-type motherboards** only have two DIMM slots: having four actively opposes their purpose.
* And yes, loading an XMP/EXPO profile to get the advertised 3000CL60 or w/e counts!

Of course it isn't normal, that's why I made my comment, to highlight the contrast. And no, my stack is optimized, you have no idea what I'm doing, yet somehow feel confident enough to know what my stack should/shouldn't look like? Man, the hubris of some people...
Next you'd probably tell me my Threadripper 9970X and RTX PRO 6000 is overkill, based on some other unrelated metrics.
Your system sounds great to me, curious what you have going on!
