Computer is built.
My ram (Gskill Trident Z 3200 CL14) OCed to 3200 (with advertised timings) by a click of the XMP profile. No fuss. I got lucky to be sure. Still getting things settled, and haven't tried OCing the CPU, yet. Boot times are very quick, and I noticed a solid reduction in load times on games and a few other applications seem much zippier. I was coming from a 2500k, though. It (the 2500k) is still a good processor, but it is a very noticeable difference.
Anyway, I was in a rush building it. So, the wire management hasn't been looked at much past getting them out of the way for airflow. It looks ragged, but runs really well. I'll clean it up in the next few days, and eventually get my old PC up and running again with a fresh install for a home media server (music, dvds, blurays, etc) so I can rip my media on it and stream it to anything with wifi. That way I can box up all my physical media besides my Vinyl. I still need a Bluray burner for that, though. I also may need more storage. I may get a smaller case for the old PC, too. The CoolerMaster HAFX is a bit too big for my tastes these days. We will see.
NVME and booting off a M.2 Samsung EVO 960 500gb worked immediately. All Mobo features were working immediately without a driver update (I of course went ahead and updated them anyway). It almost felt like a Linux install in how everything just worked out of box with little fuss. Even wifi and the on board sound card (even though I use a USB DAC most of the time anyway) worked immediately.
I am not using the Ultrafast boot feature as of now, but Asrock (I got the Taichi x370) has a solid in Windows App that will restart from Windows directly into UEFI. This is because the ultrafast boot bypasses the bios splash on boot up. So, I might reinstall Windows with that in mind now that the Bios is updated, and I have all the current drivers/software on a USB stick. I didn't want to mess with it right off the bat. I just wanted to make sure everything worked without error. So, I will likely wait a week or two before I do a Windows reinstall, and make sure everything remains on the up and up.
It wasn't all painless. I had some issues with my case fans running @ full RPM (Noctua 3000rpm fans), and they sounded like it was a Nasa launch. However, this can be chalked up to me building it after being awake for 16 hours and doing a 12 hour shift at work in the middle of that 16 hours. I was too tired for my own good. Got the fans under control and started updating/downloading stuff and got some sleep when I started nearing the 24 hours without sleep mark. It is still a bit louder than my previous PC, but it is much more normal now. My old PC was a handful of larger fans (140mm +). This one is all 120mm. So, a little more noise isn't out of the ordinary. Now it'll be minor tweaks from here on out.
I am really happy with the new build, and have zero regrets moving to Ryzen. Take that for what it is worth. Just my 2 cents.
