So I wanted to follow up with you again. I may be going to Microcenter this weekend, and they have the Aorus Master in stock. Are you liking the board and BIOS? My other in-stock X570 options (excluding the $700 boards and the low end boards) are:
Asus CHVIII Hero (Wi-fi)
Asus Prime Pro
Asus Rog Strix
Asus Rog Strix E
Asus Pro Workstation
Gigabyte Aorus Pro
Gigabyte Aorus Elite
Gigabyte Aorus Ultra
Asrock Steel Legend
Asrock Taichi
For me, it comes down to the CHVIII, Taichi X570, and the Gigabyte Aorus Master. Recommendations? I was planning on using the included cooler, though I do have a spare 240 AIO I got on sale awhile back. Obviously a 360 would be better but I don't think I can justify the cost. I don't think I'll be doing any manual overclocking but on the other hand, the room it will be in can get warm (upper 70s) so at some point I may need to go that route.
I'm thinking I'll let the dust settle a bit with my X370 Taichi BIOS situation and then maybe get a 3700x for that system. I think I've decided to go with X570 for my 3900x build.
This is the RAM you're using, correct?
It's really dependent on which board has the features you need. There seems to be zero point in trying to overclock the 3900X, so according folks like Buildzoid, the VRM design on the $200 and up motherboards is perfectly fine.
I'm not 100% happy with the F5G bios on the aorus master, so I'll flash the backup BIOS with F5E, and see how it is. As far as finding things, it's actually really easy, and mostly intuitive. A lot of the settings you'll want to tinker with are in the Tweakers category in Advanced Mode. I forget the exact name, but there's a subsection in Settings right below AMD CBS that's not shown in the motherboard manual, where you can also tweak other CPU-related settings (that's where I disabled PBO, since there seems to be minuscule difference in performance with it enabled/disabled). Everything else is logically organized.
Here's the one thing I don't like about the F5G BIOS: If it sits there during boot for 30-40 seconds, the monitor has no signal, and the debug LED shows 02 or 04, you may as well just reset the power on the power supply and try again. Those two codes aren't listed in the extensive list in the motherboard manual, so I have no idea what they mean. I've yet to experience any of the specific error codes listed (50-5F, D0-DF, E8-EF, or F8-FF), so that's great. This is the sole issue I've encountered, and it's intermittent. This desktop is gonna be on 24/7, so even if it still happens with F5E as well, I won't encounter it very often (excluding Win10 updates).
Other than that (and Win10 Pro being an absolute PITA. I hate it), things are running very nicely on my new system with the exception of Ryzen Master crapping out after updating Win10 to 1903. No clue what it's malfunction is, but CPU-Z and AIDA 64 work fine, and VMware Workstation Pro 15.1 installed without a hitch (I'm still transferring 12TB of files over to the new desktop, and need to setup VIRL 1.6 in it again anyway).
And yup, that's the exact RAM kit I purchased.
Whomever said those LPX DIMMs are 31mm was off, as I had to raise the front fan on the NH-D15 a little bit. Not as much as if I'd pick up a G.Skill or Ballistix kit. though. That height was the main reason I picked up that RAM, so if you prefer either of those two, and are using a CLC or a cooler that doesn't overhang the DIMMs as much as mine, you'd likely be just fine with those after enabling the XMP profile, too.
I do wanna tinker with the case fans a bit, to see if I can drop the temps a bit further, as well as see if removing the filters makes an appreciable difference. It's a meshify S2, and if I had to do it over, I'd pick up an O11 Dynamic instead. I've got 7 NF-F12 intakes (4 front, 2 on top right in front of the CPU cooler to blow in more cool air, one in the PSU shroud to aim up at the GPU, and maybe get some cool air in the back, where the SSDs and HDDs are). There are two exhaust fans, both behind the CPU cooler (one is up top).
