DEJ915That's the Intel supported specification is to downclock with two dimms per channel so it's supposed to do that by default, it's not a bug. XMP with 4 sticks though, best of luck. https://youtu.be/J4_a0vXGo5U?t=2594
rjbarker...its called new tech and BIOS update and there have been many already..did you check out Shamino's BIOS Updates page? btw that Thread has 5 or 6 people complaining:- one is using Asus AI OC (no enthusiasts I know uses it to OC) - did they try XMP II ?- Of course there going to have to re-set there OC's as they updated the BIOS (thats normal)- One of em is complaining he is isnt stable anymore on "Auto" with XMP and 64G (16*4G sticks)..hhhmm, maybe push your vDIMM and SA up a bit...just a thought.- 4 DIMMS is going to be a bit more finicky (yes even running XMP) with "daisy chain" topology....probably coming from T-topology whereby it was the opposite.- One flashed back to previous BIOS and said it was ok. Its all new tech man,,,of course there will be bugs that will be addressed with BIOS updates.One thing with Asus (especially having Shamino onboard), he provides almost daily / weekly BIOS updates for all there ROG Boards.Thats what makes Asus Boards pretty darn good (the BIOS support). My Z390 Maximus Extreme Board is how many chipset generations old and I believe I had 3 BIOS updates this past year alone...a few of them for both W11 compatibility, as well as Rebar...one other for addressing some minor issues that popped up after the initial rebar BIOS update. I'm sure there will be lots of bugs n BIOS updates with Evga Boards when they make there debut, there were I recall on the Evga Classified Boards I owned.

For the last few generations (X99 and X299) we've been blessed with Quad Channel memory. Seems a shame to not have Quad Channel DDR5. I guess for the Z690 generation, it might be prudent to just get 2 sticks of 32GB instead of 4 sticks of 16GB DDR5 RAM.
