I have been experiencing a slow POST time on my new Threadripper build.
It takes 25-30 seconds or so from when I power on the system to when it displays the BIOS screen. (from there windows starts very quickly)

-I have made sure to fully reinstall Windows in UEFI mode
-There are no other programs running on the computer, just Windows 10
-I have installed the most current BIOS update
-AHCI is enabled
-RAM is arranged in proper sequence

specs:
CPU: AMD Ryzen Threadripper 1920x
MOBO: MSI X399 Gaming Pro Carbon AC
GPU: EVGA 1080 Ti SC2
RAM: G.Skill TridentZ DDR4 3200 (4x 8GB sticks)(on Motherboard's QVL list)
PSU: EVGA Supernova 850 P2 Platinum
Samsung 950 EVO M.2 250GB (boot drive)
Samsung 850 EVO 500GB SSD

I realize that this might be expected across the new TR4 platform in its early stages, but if anybody knows of any other reason this might be occurring I would really appreciate some help.
I have been reading that this is a common issue across many MSI motherboards running the AM4 platform and was wondering if this problem might extend to their TR4 boards, (and if I should return it and order the Gigabyte Aorus X399 Motherboard instead).

Thanks in advance!

I think that's going to be a normal thing for Threadripper, or the x399 anyway.

Intel's x58, x79, x99 and x299 do take longer to boot up than the main stream counter parts like x77, z87, z97, z170, z270.

I'm pretty sure it has to go through extra steps before loading into windows, we are talking about borderline server class stuff here. A server with 2 CPU's and a ton of RAM will take even longer to boot than a server with 1 CPU and fewer sticks of ram, fewer steps it has to go through to make sure everything is in check. Your Threadripper CPU is pretty much a server chip, top of a new platform.

Keep, your bios updated from time to time and it could improve, Ryzen (Main stream) had some issues with boot up and is slowly improving...

I went from a z77 with i7 3770s with about a 10 sec boot time to an x99 with an i7 5820k to about 30 - 35 sec boot time, it just takes longer with these Enthusiast/server class hardware.

I'm not too advanced with the tests that bios have to complete in order to boot as I'm more of a hardware kind of guy, Someone else with more experience than I would have to chime in to give you more details.
