      description of the problem

      System works fine when powered on but when I reboot or either power off / on the machine hangs at the bios boot screen ( that with logo and F2 to enter setup ) and this happens sometime not every time ( randomly ). When it hang keyboard not work (ctrl+alt+canc not work) and to restart the system I need to power off and power on again or reset.

      This is really a problem for example when I need to reboot the server from a remote station. I tried to update bios at the latest 1001 version but that not helped, tried to reset CMOS and loaded bios default settings, nothing changed it hangs sometime after a reboot or a power-on.

       

      repro

      Though I did not find an exact way to reproduce the problem I can easily reproduce by rebooting more times during hours ( sometime it restart correctly, sometime it hangs ).

       

      question

      Is there a well known solution to this problem ? and if so there will be some expected BIOS update in near future ?

      I would like to use this cpu for the provided performance but I need also realiability and I can't suppose that the server hangs after a reboot so in the meanwhile I'm forced to downgrade the CPU to an A12 9800 hoping the problem doesn't occurs anymore.

          I'd suggest asking on the ASUS forums, but I bet the problem is your RAM. HX421C14FR/16 does not appear on the QVL list, and Ryzen is very picky about which RAM it can work with.

            thx for the reply, I posted the same to ASUS forum board,

            for the RAM

            https://www.amd.com/system/files/2017-06/am4-motherboard-memory-support-list-en_0.pdf

            HX421C14FB results as supported and mine

            HX421C14FR exactly the same apart color coded in the last letter ( R=red B=black )

                The manufacturer of the memory chips (Samsung or Hynix) can vary between models, even if it's as little as a color difference. What does AIDA64 says the manufacturer is? If it's Hynix, that's going to be an issue ESPECIALLY with that board (I owned that board, I hated it, temperamental as an antique car)

                I found the root of the problem,

                I connected 3 backplanes that power 3+3+2 disks to a single rail instead to distribute them among separate rails

                 

                WRONG:

                CORRECT:

                      Sure, if your system like mine you have for example 8 SATA disks,

                       

                      BACKPLANE1 - DISK1, DISK2, DISK3

                      BACKPLANE2 - DISK4, DISK5, DISK6

                      BACKPLANE3 - DISK7, DISK8

                      Note: each backplane required 2 PATA or 2 SATA power connections

                       

                      and having 3 cables rails with each 3 connectors, as shown in diagrams previous post, say

                      RAIL1 - SATA1_1, SATA1_2, SATA1_3

                      RAIL2 - SATA2_1, PATA2_2, PATA2_3

                      RAIL3 - SATA3_1, SATA3_2, PATA3_3

                       

                      what caused the problem for me was that I connected backplane power plug in follow WRONG way

                       

                      BACKPLANE1 ( require 2 power plug ) : I was connected 2 power plug of backplane with a "splitter" to a single SATA1_1

                      BACKPLANE2 ( require 2 power plug ) : I was connected 2 power plug of backplane with a "splitter" to a single SATA1_2

                      BACKPLANE3 ( require 2 power plug ) : I was connected 2 power plug of backplane with a "splitter" to a single SATA1_3

                       

                      this resulted in overload of the rail so that power supply goes down in protection mode expecially in reboot phases.

                       

                      The RIGHT way instead was to connect in distributed manner bearing n mind that each RAIL has a specific power dimensioning ( in my case 3 unit foreach ) :

                       

                      BACKPLANE1 : to SATA1_1, SATA1_2

                      BACKPLANE2 : to SATA2_1, PATA2_2 ( through converter PATA/SATA )

                      BACKPLANE3 : to SATA3_1, PATA3_2 ( " )
