B350m pro4 stuck in boot loop

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi everyone !
This is my first post on the forum and my new build after 15 years.
I have recently purchased the following components:
- Asrock B350m pro 4
- Amd Ryzen 5 1600x
- Fractal Design Celsius S24
- KFA2 1080 Gtx Exoc Sniper 8Go
- Hyperx HX426C16FW2K2/16 (2666Mhz 2x8Go)
- EVGA 210 650w
- Western Digital SSD 250Go
- Western Digital HD Blue 2To
- Fractal Design Mini C

However my build won't post, I'm stuck in a boot loop... All the fans spin and the leds of the gpu light on white.
I have tried the following things :
- 2 ram sticks in positions A2 and B2 (as recommanded), and every other positions positions with 1 or 2 ram sticks
- Minimal setting (out of the pc case) with only the motherboard, power supply, cpu, cooling system, graphic card and ram
- I have also tried the different video outputs on the motherboard and graphic card
- I have seen that the motherboard supports the R5 1600x only after the bios update 2.40, so I have ordered a R5 1600 which is supposed to work on all bios versions, and I still face the same issue
- I have plugged the correct pin for the power supply of the cpu and graphic card
- I have waited at least 6 reboot everytime
- I have removed the bios battery and used the bios reset jumper
- Also, I have checked that the ram is compatible with the motherboard & cpu

I guess that there are some chance that the motherboard arrived DOA, so I've asked for a replacement which should arrive soon.

Now I'm a little bit out of options, this is why I'm looking for your kind help.

Cheers,

	Please check that you have connected the 8-Pin CPU Power located in the upper left of this motherboard. This is the #1 or #2 reason for what you describe, and is commonly overlooked. Even by me every now and then Too, please list the memory Kit P/N. Ryzen is picky.

	Thank you for your prompt answer Sure thing, I have connected the 8-Pin CPU in the correct spot. I have the "Hyperx HX426C16FW2K2/16" which is listed as compatible with the b350 chipset. https://media.kingston.com/pdfs/hx-product-memory-ddr4-amd-ryzen-and-hx-compatibility-us.pdf However I realize that it is listed as compatible with some R7 processors but I can't find any reference regarding R5.

	Processor don't matter. Directly above the top of PCIE1 is your BIOS chip, with a sticker over it. What is printed on this sticker?

	I'm thinking your BIOS needs flashed as it's most likely older due to your location. By the time parts make it into sales/dist channels in your area we Mods usually see this. I checked Kingstons website and this Kit is certified compatible by them for your AB350M Pro4.

	Thank you. The bios version is 2.30. I have purchased the components from amazon italy. Could you help me understand this. Does bios need a flash to be compatible with the processor and/or the memory ? Because I have also tried with a ryzen 5 1600 which is supposed to work for all bios version.

	Hi Didjo, I was wondering whether you fixed your problem because I have the same and don't know what to do?
