TRX40 Creator - "Code 54" After Reboot

You can try;

1. Running HCI memtest to see if any errors are detected, let it run to at least 300%.
2. Increase memory voltage to 1.4v
3. Take 2 sticks out and see if you get the same problem
4. Did you get this issue with firmware 1.7? (non-beta release)
5. Look at the serial numbers on your memory, the final digits will be in sequence. Eg; 0314, 0315, 0316, 0317. Install the memory modules so they are all in order.
6. Try increasing tCWL and tRDWR to 16 or 18.

Have you tried disabling Gear Down mode and manually setting Command Rate to 2T? TRFC should already be set loose enough but you could try adding 50 or 100 to that and see if that helps as well.

What are your full system specs? POST failure on restart is probably a RAM training issue but depending on things like what CPU you have a voltage bump to vsoc might be effective, as might increasing ProcODT. Try downloading ZenTimings and posting a screenshot of it something might stand out.

Do you know what ICs your memory is using? (You can get that infor with Thaiphoon Burner) Quite a lot stands out there;

1. Disable GDM (Gear Down Mode)
2. ProcODT should be ok at 60 Ohms but you can try 68 Ohms as you're running 4x sticks.
3. Try reducing VDDG voltage I've found on the 3000 series at least if that voltage is set too high it can actually negatively impact stability, on my 3700X with 32GB 3600MHz Klevv BoltX I have it set to 0.85v, it could probably go even lower than this. Try 0.9v and slowly work your way down to see if that makes a difference.
4. You have a lot of oddly aggressively set timings considering you are running 4 sticks across all DIMM banks. Try changing TRRDS to 6 or 7, TRRDL to 9 or 10, TFAW try 45, TWTRS try 6 or 8, TWRWRSD & TWRWRDD try 7 or 8, try a TCKE of 9. Lastly TRDRDSD & TRDRDDD might be a little tight as well try a value of 5 or 6.

Micron is a real pain on Ryzen, the only CPUs I have that (kind of) run Micron memory happily are based on Zen+. Hynix based memory works very well on Zen, Zen+, Zen2, etc though. As does the now old and ever growing in expense B-Die. You could try switching CMD2T to 2T to see if that works, disabling PowerDown might help too. Outside of that though I think you're out of luck unless you're happy to reduce the memory frequency a bit.
