That a negative on the PCI-E Connector. Made sure it is the 8-pin CPU Power and it took no forcing.

I'm thinking its a bad Mobo. Triple checked the compatibility of the CPU:
https://www.asrock.com/support/cpu.asp?s=AM4&u=613

RAM is not explicitly on the QVL.
Using - CMW32GX4M2Z3600C18 (2x16)
QVL - CMK64GX4M2D3600C18

I should at least get to BIOS and get a Memory error if the RAM is not compatible.

Still looking for solution here...RMA the board and hunt for something different?]]> Wed, 24 Jul 2024 09:17:19 +0000 https://forum.asrock.com/forum_posts.asp?TID=51848&PID=134929&title=asrock-b550m-pro4-no-post#134929 https://forum.asrock.com/forum_posts.asp?TID=51848&PID=134807&title=asrock-b550m-pro4-no-post#134807 Author: Xaltar

Make sure your 8pin CPU power is connected and is the correct connector. The PCIe
8pin power can often be forced into the CPU 8pin header a little too easily. ]]> Mon, 22 Jul 2024 15:08:29 +0000 https://forum.asrock.com/forum_posts.asp?TID=51848&PID=134807&title=asrock-b550m-pro4-no-post#134807 https://forum.asrock.com/forum_posts.asp?TID=51848&PID=134785&title=asrock-b550m-pro4-no-post#134785 Author: Kai-Lord

Oh, and I popped the CMOS and discharged residual power]]> Mon, 22 Jul 2024 05:20:15 +0000 https://forum.asrock.com/forum_posts.asp?TID=51848&PID=134785&title=asrock-b550m-pro4-no-post#134785 https://forum.asrock.com/forum_posts.asp?TID=51848&PID=134784&title=asrock-b550m-pro4-no-post#134784 Author: Kai-Lord

Hello!

Upgrading my son's PC and the Mobo is not posting.

https://pcpartpicker.com/list/FFmg4d

Mobo - B550M Pro 4
Processor - Ryzen 7 3800X
RAM - Corsair DDR4 32GB (2x16) 3600Mhz
GPU - Geforce GTX 1080

Assembly went fine, all headers and connections are properly seated

Troubleshooting steps taken
- Tested single RAM stick all slots
- Reseated CPU & Checked for bent pins, all good
- Reseated PSU Headers
- Removed all other header (HD Audio, USB, SATA etc.)
- Tested against known good HID Devices
- Remove Mobo from case and tested in isolation

Continuing to see No POST lights on HID peripherals and Red Lights on DRAM and CPU mobo indicators.

According to the Mobo specs, should support the RAM fequency and PRocessor with stock BIOS. No way to flash BIOS without POST?

Any leads would be appreciated.

Cheers! ]]> Mon, 22 Jul 2024 04:53:02 +0000 https://forum.asrock.com/forum_posts.asp?TID=51848&PID=134784&title=asrock-b550m-pro4-no-post#134784
