          I don't quite understand your question. Can you clarify it further.


          Also please post your Computer Informations as per AMD Forum Rules: INFORMATION REQUIRED WHEN POSTING A QUESTION .


          Are you saying that you are having a difficult time installing your Ryzen CPU on the Motherboard's Socket?  Or that you are getting an error message when booting up?

                  Do you have the correct BIOS version for your Ryzen?


                  Your Motherboard should have the minimum BIOS version of 0318 installed

                  This is the latest BIOS for your motheboard: https://www.asus.com/us/Motherboards/PRIME-X399-A/HelpDesk_Download/



                  Version 06012018/05/025.29 MBytes

                  PRIME X399-A BIOS 0601
                  Update AGESA
                  recommend to keep C-state [enable]

                  What is the entire Q code (E8, 83, etc)?  Is your CPU fan connected to the Motherboard? Are all your Motherboard power connected?  Which version of Windows are you currently have installed?

                  According to your Motherboard's Manual, your Motherboard has "3" Power connectors from the PSU to the Motherboard. See the image below.

                  If your CPU Fan does not turn on that is a very bad sign. Your CPU will Overheat almost immediately without the fan running.

                  Here is a link to your Motherboard's Manual from Asus Support: http://dlcdnet.asus.com/pub/ASUS/mb/socketTR4/PRIME_X399-A/E13889_PRIME_X399-A_UM_V3_WEB.pdf?_ga=2.167283127.888444841.1…

                  I inserted several photos from the manual that will help you determine if you connected your motherboard correctly and what the Q-codes are. Look at each one and verify. This is taken from the link above from your Manual:

                      Hi elstaci again,

                      No, not in the list. The Ripjaws are a 2-Modul kit 2x16GB F4_3200_C16D-32GVK CL 16-18-18-38-1.35V. Where do i get the current Bios-Version that is installed? Do you suggest to update the Bios first and than tray again? You don't have to post pics, I have the Manual in hand LOL. As for the Q-Code that is not documented, no Beep, no reaction, only the RGB-lights which is pretty useless.


                      Power Connections: 24pol ATX, 8pol CPU, 4Pol CPU, PSU Thermaltake Toughpower Grand 850W also new


                      Thanks again

                          You are probably in the minority who actually reads the Motherboard Manual. Normally I attach photos from manuals to help Users.


                          When you turn on power, What exactly do you physically see that is running? just the RGB lites of the motherboard? The CPU fan or GPU Fan or Case Fans aren't running?


                          No need to update the BIOS yet until you are able to get an image on your monitor and the computer is booting up normally.


                          No chance of you installing another CPU on your motherboard is there? Sounds like a hardware failure so far. Is your PSU have the right power switch on 120 or 220v?  The motherboard's troubleshooting LED's, none are lit up?


                          What is the exact Error code you are getting from the Motherboard? Even if it is not listed?


                          I would open a Asus Support Ticket and see if your motherboard needs to be RMAed.


                          Plus, even if you get your computer working, with a non-supported RAM MEMORY installed it may not be quite compatible with the Ryzen CPU and cause you further problems.


                          Do you have your monitor connected directly on your GPU Card and not the motherboard?  Make sure your GPU card is installed in a PCIe x16  x 8/16 slot on the motherboard.


                          Try booting up with just one RAM MEMORY MODULE installed instead of both. Just for troubleshooting purposes only. Make sure your PSU is working (fan running if possible) and the PSU connections are securely connected to the Motherboard.


                          You mentioned that the CPU Fan was not running, after turning on the computer and the CPU very hot to the touch or cool?

                        tomdooley, please tell us more:  UEFI version, Drives, Power Supply.  Also tell us the status of Onboard LEDs that elstaci pointed to above.  Are you getting this code?  -  0x80 – 0x8F OEM DXE initialization codes

                        I am not sure what this is pointing to but are you Disabling CSM in your UEFI?  While we are in the UEFI, please do a Clear CMOS as defined by your User Guide.  Make sure the CPU power connections are plugged (all - 24 pin, 8 pin and 4 pin) correctly (4-pin can be rotated 90 degrees) and that they are CPU not PCIe cables.  Thanks and enjoy, John.

                            HI John,

                            I don't see anything on the screen , no signal. That indicates the MB doesn't send any data. So no UEFI nothing HDMI connection. Have Clear Cmos done before and I made sure the power connections are ok, no PCIe-cables. On the PSU cpu-cables are black, the PCIe-cables are red and correctly marked.


                            Thank you for reply

                                Thanks, tomdooley.  Please tell us the status of Onboard LEDs (upper right hand of your MB) - please see elstaci post above.  They should be useful - all off is OK.  Also is there any hex code in the Q-Code Hex display, lower left hand of MB?  Things to try:

                                1. Remove all add-ons (Memory, video, drives, etc... all but processor) and see if will give a Q-Code.

                                2. Re-seat Processor and check for bent pins in the socket.

                                If item 1 gives a Q-Code, then add memory and boot, then video and boot, etc.  What is your processor cooler and where is it plugged?  Do you have a volt meter to measure voltages?  I am concerned that the CPU fan is not turning.  Are any other fans turning?  Thanks and enjoy, John.

                                    Hi all,

                                    Thank you for trying to help me. I think too that's a HW-Issue and will send MB and CPU back to the Vendor.


                                    Thanks again

                                        The only other things I can suggest and bare in mind I'm walking into the middle of this.


                                        Ensure fan header for CPU Cooler is plugged into the CPU cooler fan connector and not another by accident.

                                        Ensure Vid card is in the first slot and has all the pre requisite power cables attached.

                                        Ensure your connections are solid to your PSU and you have everything in the right connection holes if it is modular.

                                        With the power disconnected and using anti static protection remove the memory modules and leave them out. reconnect power - are your results any different when powering up?

                                        Remove motherboard from chassis and try running it on the bench in case you have a chassis short.


                                        Sorry if you've done all of this just trying to help as I know how frustrating this can be.

                                            Hi all,


                                            the MB and CPU are currentlly in RMA-Process, so no more testing on my part. @falloutboy yes I have all of your suggestions tested and nothing changed. Meanwhile I recieved a tip for the mounting of the CPU. AMD says to open the socket follow the screws 3-2-1.That's OK. To close the socket in reverse order, but it's better to

                                            turn on screw 2 and 3 first one or two turns before turning screw 1 to the limit, then turn rest to the limit.


                                            To anyone who reads this: Use the Mounting-Tool that is provided with your Threadripper. It's a Torgue-Tool which clicks at the right torgue

                                Check to see if there is a BIOS update to better support your CPU and memory timings
