Question No POST with DIMM in A1 or A2 slots

I have a new ASUS ROG Strix Z490-H Gaming motherboard with a i9-10900K installed. I have two memory kits I've tried with it a set of Crucial Trident Gold (F4-3200C14D-32GTRG - 2x16 3200CL14) and a set of G.SKILL Ripjaw V (F4-3400C16Q-64GVK - 4x16 3400CL16). With the motherboard memory settings of 3200CL16-16-16-34 at 1.35 V ( well within spec for all the memory) the system will boot with any one or two of the DIMMs in B1 and/or B2 (I've tested all six DIMMs this way). However it won't get past the memory error LED If anything is plugged into A1 or A2 (both with and without B1& B2 populated).

I'm starting to run out of ideas and haven't found a good set of words to search for so I'm looking for help. Happy to take input on what might be going on or steps to debug this further.

Thanks
-Greg

Pulled the CPU, pins look fine. Also pulled the Motherboard just to double check for a short or any sign of damage on the back, but didn't see anything. Reassembled with no change.

Well I ordered another motherboard (ASUS ROG Strix Intel Z490-F Gaming) so I can see if it's a non-obvious issue there or if it follows the CPU. Fingers crossed
