Nice build DooKey, have you had a chance to play with it at all yet? Also curious on the RAM, does it have any way to control the LED colors / patterns?
I have Trident Z RGB kit also, default is a random rainbow pattern, but there is software available however these kits are fragile on AM4 and die easily (mostly on DRAM OC), one guy left settings at stock and everything was fine but as soon as he used RGB software next reboot one module was dead as a doornail.
I noticed in my MSI X370 Titanium that even with DRAM voltage set to 1.28V it spikes to 1.31V and DRAM is rated for 1.35... I could imagine setting it to 1.35 the spikes would be much higher and could be the reason for modules kicking the bucket. Might have something to do with the LEDs as it seems to be mostly isolated to the RGB kits.
I have mine (3200 CAS 16) set to stock clocks (2129) and MANUALLY set Voltage to 1.28V (1.2V Nominal). So far so good, waiting for BIOS to mature before pushing clocks and voltage or playing with RGB software.
One of the biggest problem with clocking DDR4 kits to their advertised values right now on AM4 is that everyone is stuck at 1T command rate and every kit's rated specs are for 2T, so 1T is already pushing it, compounding things is most BIOSes having limited timing options to tweak.
