My new build will only post with one stick of ram and only in slot two. If I put in the second stick the computer will not boot. If I put the module in any other slot I get no activity. I have tried a different brand of ram and get the same results.
ASUS B650E-F (I even updated to the most recent bios)
Ryzen 9 7900X
Gskill 32Gb 2X D5 6000
Corsair 32 GB 5600
Any of the ram modules will work in slot two. Post is quick and I can get into Bios to change memory timing. I reseated the CPU but that didn't help. My error LED (yellow ) is constant with two sticks. With one module the LED is only on for a few seconds.
Any thoughts or suggestions or do you think I have a flaky motherboard?

To verify it doesn't boot with a single stick of RAM outside of just one slot? This also happens with both sticks of RAM being used one at a time?
Only boots with one stick of ram and only in slot two.
One Stick of Ram
Slot 1 = NO
Slot 2 = Yes
Slot 3 = No
Slot 4 = No
Two Sticks of Ram
Slots 2 & 4 = No
Slots 1 & 3 = No
Assuming you have tried placing the other stick of memory in the slot that appears to work in order to test the module. Keep in mind that after changing slot configurations on the board with DDR5 memory, it could take a little while for it to complete it's initial post test, changing the location in the board will trigger a new ram test during post. It is possible you have a bad slot in the board.
In all the failed configurations I waited several minutes to see it I could get a successful post. I'm pretty sure I have a bad memory controller at this point. Perhaps it's time to try a different MB. I'll try calling Customer Support for advice. I hate having to return the board as my nearest Microcenter is 75 miles away. The other alternative site is 100 miles away. 😅 Fortunately my build last fall went without a hitch.
Sounds like you've tried multiple sticks in each slot and only 2 works. This means the other three slots are defective. Could be a bad IMC like you said, more likely to be a defective motherboard. I'd check the CPU socket for damaged pins.
Only because this solved several issues over the weekend for us in the tech shop, are you able to run a BIOS update? And when you can get it posted with one stick do you have your bios settings on the default (no DOCP)
I gave up and installed another motherboard and completed my build. CPU was fine, Memory was fine at 6000. It was the MB that was faulty. Using the new build now. Cloned my old system and all is back to normal (except MS Office for some reason).
I was already past the 20 day return window when I reached out for help. If the socket was bad before, it definitely is now. I see a shiny spot on one area of pins which I may have caused packing up the MB for a return.
Thanks to those who reached out.
Good to hear it is up and running now, if you do have any other questions for us, please let us know.
