Just bought a B550M Pro4 motherboard, Corsair DDR4 3200MHz memory (8GB x 2)and an AMD Ryzen 5 5600x processor. have a 750W power supply. When I hit the power button the boot and VGA post lights come on, no post, no keyboard lights. I am trying to use an HDMI monitor. Have checked the cables all are good to go. I know I need to flash my BIOS in order to use this processor, but I cant even get to the bios screen. Any ideas? |

| Correction it is the CPU and DRAM lights |

What GPU are you using? The 5600x will require that you have a dedicated one. -------------

I was planning on using the on board card, but I tried installing my NVDIA GTX960 2GB PCIE card with no luck either |

The onboard outputs require an APU to use. An APU is a CPU with built in graphics. Your 5600x is not an APU and therefore the display outputs on your motherboard won't produce any signal. -------------

As for the no post issue, what BIOS version is on your board? It should be printed on a small white sticker on the BIOS chip. The 5600x will require BIOS version 1.20 or later. If you are on an older version then you will either need to borrow/buy a compatible CPU (with the BIOS version you have) and update or take the board to a tech service center and ask them to update it for you, whichever is most convenient. Here is your CPU support list: https://www.asrock.com/mb/AMD/B550M%20Pro4/index.asp#CPU" rel="nofollow - https://www.asrock.com/mb/AMD/B550M%20Pro4/index.asp#CPU -------------

What would be required to utilize the onboard graphics, a totally different processor? I apologize, its been about 10 years since I built a computer and it seems to have become not as simple LOL |

No need to apologize  You would need a CPU that ends in a "G" The G indicates built in Graphics. A "GE" CPU would also work, the E just stands for Efficient which indicates a lower power CPU. The actual term for CPUs that have a GPU built in is APU (Accelerated Processing Unit). If the 5600x isn't working for you then you may want to look at a CPU from the list I linked that is supported under "ALL" BIOS versions, one that ends in a "G" suffix. This is where things get tricky, BIOS versions and compatibility dependencies. The issue is that the only APUs (G class CPUs) that are supported under all BIOS versions on your board are OEM only parts (only sold to manufacturers like Dell etc). While you can get hold of them it's typically only on sites like Ebay or Aliexpress. There you run into issues with lacking warranties etc. You best option would be to get the board's BIOS updated to the latest version by an IT service center or the like then be able to use any of the G class APUs listed. If you do this before returning the 5600x you can at least test everything using a dedicated GPU and make sure everything else works before ordering the new APU and returning the 5600x. -------------

Just to clarify, ASRock typically updates all the boards they ship out to the latest BIOS available at the time of shipping. The problem is, if the boards sit in a warehouse or on a store shelf for months before being sold the end user often ends up with a board that has an older BIOS version, one that may not support newer CPU/APU generations. The store is supposed to update the boards before shipping them to customers (most good ones do) but many don't. I suspect this is why you couldn't get the system to boot even with a GPU installed. -------------

I think I'm in the same boat. Just finished a new build with my son with a Ryzen 5600G Proc in a B550M Pro4 MB. Per the list posted earlier that chip is certified with BIOS 1.80, but the sticker on our MB is 1.50. We're caught in the catch 22: if we could boot to a CD drive and update the BIOS, we're golden, but since the graphics are bundled with the CPU (that won't boot), our monitor remains dark. I think at this point I will try the AMD borrow-an-older-CPU deal: https://www.amd.com/en/support/kb/faq/pa-105" rel="nofollow - https://www.amd.com/en/support/kb/faq/pa-105 Or try to beg/borrow/steal a separate graphics card. |

Check your local used listings (Facebook marketplace etc) for old used PCIe GPUs. You can usually find something old that is useless for gaming for cheap. I picked up a Geforce 9500gt the other day for the equivalent of about $5USD. I had to go and physically collect it but it saved me paying shipping and waiting. The other alternative is to check with your local IT stores and see how much they would charge to update your BIOS for you. Some where I live don't charge much given how common outdated BIOS issues are. -------------

I have the same MB and CPU and had to update the bios to support the CPU. You will need an AMD Matisse, Renoir, or Vermeer CPU and a GPU. I used a 3600 CPU and an Nvidia Geforce 1660 GPU to upgrade the bios. |

Thanks Xaltar and MadScientist. Gives me hope! Question: when you swapped your Ryzen 5600 back in, did you take out the GPU? Curious if you have both a graphics card as well as the "G" processor with embedded graphics installed, how does the system "choose"? Thanks! |

| Well AMD gave me the run-around and is not going to lend me a legacy processor to boot up with and update the BIOS. Is there a local service provider that could update the BIOS for me? Or am I SOL? I live in the Portland, Oregon, USA area. |

| Tale of woe continues: AMD relented and sent me a Ryzen 3 3100 CPU. Found a cheap GPU on Craigslist. Hooked everything up...still did not boot. Solid red LEDs on the mobo. So now I'm returning the motherboard so ASRock can update the BIOS. Hopefully it's not something else. |

If ASRock updates it for you they will double check to make sure everything is working properly on the board so at least you will know it checks out. I have been assured by my contacts in ASRock's tech support department that they test every board they get in for updates before returning it  -------------

Wanted to pen the epilogue of my tale for posterity. Got the MoBo back from ASRock, plugged in the CPU and all the bits. And it fired right up! Thanks ASRock! |

Fantastic, glad to hear it   -------------
