You're missing nothing by not installing AISuite except all the headaches. The first thing you will do after installing it is...uninstall it. You need zero of those programs. If you want Aura, just install Lighting Control (although I've had no luck with 1-0-0-5-28 version). If you want BIOS updates, just download the ZIP and extract the CAP to a USB stick.
I built a home PC with the X370 version (ROG Strix X370-F and R5-1600) just within the last two weeks, and all I can say is I'm not pleased with the 3401 BIOS. The lesser model Prime X370-Pro is already at 3404, having had 3401, 3402, and 3403 already. I have 10 BIOS files saved for the Prime X370-Pro since July 7, 2017. And a few I didn't download or keep since they were pulled by Asus. Not nearly as many it seems for the Strix compared to the Prime. I've had the Prime X370-Pro and R5-1600 in the garage since June 2017 doing vSphere hosting duty.
If anyone finds this thread having stability problems with Ryzen, one of my first questions would be "How many DIMMs?" The appropriate answer is TWO. Not to say 4 is impossible, but you will have more stability problems, and you will be limited in your RAM speed quest. Seems like 2400 is max stable IMO with 4 DIMMs on Ryzen. I tried 4x8GB G.Skill Trident 3200 and Chrome couldn't even successfully load a tab. I moved that set of RAM over to a Kaby Lake i5-7600K and Chrome also couldn't successfully load a tab. Turned RAM down to 2800 on the 7600K and found stability there. Tried upping DDR voltage, MC voltage, etc, to no avail.
I got into that predicament by buying a 16GB set of RAM on Black Friday for a "good deal" knowing that the price was likely to keep going up. It was preemptive, without having a specific home the RAM, just guessing that it would come in handy by year's end. And it was more expensive by January when the need arose, but that meant that I needed another set to actually do anything. Cities Skylines and VMware Workstation put me firmly in the 32GB camp - less is painful. Also painful is a constantly crashing system, especially BSODs implicating Memory Management. A few nights ago I lost several hours of city-building and at that point, shut the Ryzen system down and ripped out the 4x8GB G.Skill Trident 3200, and replaced it with 2x16GB Mushkin Ridgeback 2400, which has been perfect so far.
I've had so little stability from the RAM until now that I haven't even fiddled with overclocking this one yet! The Ryzen ESXi server in the garage runs 4x16GB G.Skill FlareX 2400, and I've had the occasional purple screen and the occasional hung/pegged VM (usually my DNS so it's pretty easy to spot: get home from work and host names won't resolve or browsing sucks), but the many BIOS updates for the Prime X370-Pro have helped (though there has been the occasional regression).
Wow, sorry to hear you're having all of those issues. It's not been my experience so far as I also updated to the 3401 BIOS (assuming same base code between models) and things have been ultra stable. D.O.C.P has these G.Skill Ripjaw V 3200 sticks running at their advertised voltage, speed and timings of 16-16-16-36. Granted I know you are running 4 DIMMS but I wonder if you don't have a bad stick in the bunch? I don't know much about RAM speeds on the Intel platform but if it wasn't able to hit 3200 on Intel which IIRC didn't seem to have issues hit above that, then it sounds like you got a bad DIMM.
The whole RAM debacle for Ryzen reminds me so much of the Phenom II X4 965 BE. They had an I and M nomenclature and you could not run RAM at the support 1333 if you populated all DIMM slots, it would run 1066. Not until they released a revised version of the 965 BE could you use all 4 at 1333. Feels just like that, at least in the beginning.
I'm going to keep an eye on my system since I'm running the RAM at 3200, no other "Overclocking" going on, which is one of the reasons I bought the 1600x, didn't want to roll silicon lottery dice and have something be unstable. One day I'll put this puppy to the test.
