[SOLVED] RYZEN 5600X & X570 Tomahawk CPU DEBUG LED

[Krypton77]

Hi all! I have a problem with RYZEN 5600X and MSI MAG X570 Tomahawk mobo. I’m installing a fresh build and my system starts, but there is a black screen and EZ Debug CPU LED is on constantly. All components are disconnected, I tried to boot using only motherboard and CPU and the problem still occurs. I replaced my mobo to another X570 Tomahawk from the retailer and it’s the same. I successfully updated the BIOS to the latest version with the flash BIOS button feature (it took about 7 minutes and then the PC rebooted). But it didn’t help. PSU and all cables are OK I tried a few times to build it again and again. CPU looks like it’s OK, no thermal paste, no bent pins. Do you have any idea what can help me?

Try do exactly. 16GB maximum size usb, renaming bios file, pressing the flash button for a few seconds to start. But short the JBAT1 pins before proceeding with all of this. Putting in one stick of ram (be 2nd slot from cpu) helped the person by the name of OnWritingTerribly.

I think my BIOS updated successfully. It was done exactly as people describe that it should be. It took around 7 mins and then the system turned off and on. But it didn’t help me.

Cpu debug led. Either bios didn't flash properly, cpu not getting power or did you install ram afterwards?

 

[Krypton77]

CPU is warm so it gets power. First I built everything with RAM installed and it didn’t work. Now I’m trying without RAM installed and it’s the same.

Try update bios again but this time try the suggested procedure, ie clearing cmos with JBAT1 first. Afterwards put in one stick of ram then try again.

MSI didn’t include jumper in this motherboard. Is it enough to touch both jbat1 pins with screwdriver for 15 seconds?

Yes, sure. Same thing if using a jumper bridging both pins.

Thank you very much. It worked after I put one stick of RAM to the slot you mentioned. Now I don’t have to buy Intel 😄 For anyone who reads this and have the same problem. You have to put one stick of RAM inside your mobo if other methods don’t help.

Wish manufacturers outline exactly what's required rather than have peeps pull hair out trying all sorts 😉

Glad it's sorted.
