Hello,
First of all, thank you to everyone who tries to help.
Here's the thing, I've decided to upgrade my old Ryzen 1600 to a 7800X3D:
CPU: 7800X3D
Mobo: ASUS TUF GAMING B650M-PLUS WIFI
RAMs: Corsair Dominator Platinum RGB - CMT32GX5M2D6000Z36
The issues is that, from the very first time I tried to use the EXPO profiles, the computer took ages to boot up (MOBO DRAM LED on), approximately >1 minute to POST, and although at some point I managed to get past POST successfully, all it takes is a reboot or shutdown to fail POST the next time. In short, I can't boot the RAMs at anything above 5200MHz, and even when I can, the POST takes >1 minute and fails most of the time (at 5200 seems to work fine, and POST times are around 10/15 sec).
I've been trying everything, watched lots of videos about this, tested profiles I've seen online for RAMs with similar modules, but to no avail. I no longer know if the problem is with the mobo / cpu, or with the RAMs because of point 2 (below).
To make things easier, I'll summarize some of the tests I've done:
1 - Test each DIMM individually (1x16) only in the first slot (according to the manual - DIMM_A2) at 6000MHz. Result = POSTs with both DIMMs at 6000MHz, but takes >1 min.
2 - Test each DIMM individually only in the second slot (this is not the correct layout in the manual, but I wanted to test if the mobo slot was damaged?), at 6000 MHz. Result = POST failure with both DIMMs.
3 - Reinstall the 2 RAMs in dual channel, according to the correct position, and tested setting the voltage to 1.4v for the RAMs (VDD and VDDQ) @ 6000 MHz. Result = Usually it POSTs the first time (>1 min POST time), but fails the next reboot or after 2 reboots.
Finally, I tested other set of RAMs from a friend (vengeance 32GB - CMK32GX5M2B6000Z30) and it did POST at 6000 MHz first try, then I tried 3 reboots and the machine always rebooted without failing to POST and, a curious thing, is that the time to POST was much shorter (15 seconds +/-). Maybe it was just luck, and maybe it would fail after a few more reboots, but just the fact that the POST time has normalized makes the behavior very different.
In short: it seems to be the RAM, right? The point is that when I tested booting them individually, they only booted at 6000 in the first slot, and not in the second (DIMM_B2), which made me wonder if it was something on the board...
However, when I tested with these other RAMs, coincidence or not, the system seemed much more stable at POST, and the POST times were MUCH shorter.
Any ideas other than changing the RAMs?
