MSI B350M gaming pro EZ debug led for CPU

luksops · May 12, 2017

Hello guys

I bought some new parts to upgrade my pc, a MSI b350m gaming pro, Ryzen 5 1600 and 2x 8gb memory. I have some experience in building, so i decided to do it by myself. I unboxed and installed all components following the mobo guide and got red lights for the CPU.

I removed all components, re-apply the termal paste and try to boot with only one stick of ram connected, nothing more, and got red light on cpu again.

I thought that could be a PSU problem (my psu have about 6 years), so i tested with another psu (another old one) and got same error. Both psu was working well before.

I dont know what to do anymore. I already followed a guide that i found here, just didn't reseted the mobo, cause all 3 parts are new.

Sorry for bad English.

Might be a BIOS issue , it needs an update , to run a Ryzen 5.

luksops · May 12, 2017

How can i update that? Since my pc dont boot.
Thanks for the reply !

Dark Lord of Tech · May 12, 2017

That's the point I was making , if it's the original BIOS you can't boot it with a Ryzen 5 and the only way to update it would be with a Ryzen 7 , which doesn't help you.

Thats a real problem. You sure that i can only boot with a ryzen 7 and thats the problem? I think i can send mobo back and change for a new one. What mobo should i get to boot with a ryzen 5?

What do you recommend?

Thanks again!

I would contact MSI support because they have that BIOS update for the R5's , could be an issue.

luksops · May 13, 2017

How can i check my mobo bios to know if it really needs a update?

@edit
And what other things can i try to do? Could this be other problem?

@edit2
i forgot to say is that all fans spins well and only stops when i turn the power off.

Is there any way to update my b350m gaming pro without a CPU?

Seanie280672 · May 15, 2017

luksops :

no, there is no way, these boards dont have bios flashback on them, as SR-71 Blackbird said, you need an R7 CPU or get in touch with MSI or even the shop you brought it from and tell them you need the bios updating to support your CPU, they should both offer this service for free, if you change the board for another, you just risk facing the same problems with another board.

The answers so far are discouraging. I have the MSI B350M Gaming Pro and the Ryzen 1700 and I have both the CPU and the DRAM lights on so I get nothing to my monitor. I have tried removing the GPU, have tried resetting the CMOS, have tried disconnecting the ram, have tried removing the CPU and putting it back in, . . . nothing has made any difference.

luksops · Jun 6, 2017

I sent my mobo back to the seller and im getting a new and updated (i hope) one. Then ill see if the problem is gone and pick a best answer.

luksops · Jun 14, 2017

I just got a new mobo and a new error too. I set up the mobo exactly like last time, and when i turn on the mobo, it gets a red light on CPU ez debug, then it goes off and the DRAM ezdebug turns on, same again with VGA led and at last the BOOT led turn on. What this problem could be?

Seanie280672 · Jun 14, 2017

luksops :

Thats not a problem, thats normal, its checking the CPU (light on) when the cpu light goes off it means its passed, then it checks the ram (light on) when it passes the light goes off, next the VGA and then boot devices.

luksops · Jun 22, 2017

It really was the mobo that wasnt updated for the 1st time. For the second error was PSU, just bought a new one, PC is working fine now. Thanks for all replys guys !!!!!

luksops :

You bought a new MOBO or PSU?

Luksops81 · Aug 21, 2017

charliefuller4 :

RMA the MOBO

This is the same problem im having rightnow i will try to update the bios to a repair store, how much u guys think will it cost

labrecquefrancis · Dec 1, 2017

Hi had the same issue this week with Ryzen 1500X. The only way I can get to the BIOS is by removing one of the 2 Ram stick (leaving one in the first slot). The minute I add the other one the CPU EZ debug light turn on and I can't go further. I updated the bios to v60 and no help so right now only 1 8Gb ripjaw 2133 works...might be a defective ram

he bought a new motherboard. but then he had the same problem. so he bought a new power supply unit for the new motherboard and it was fine.

luksops · Sep 19, 2018

I had 2 problems, mobo outdated + powersupply problems. I didnt buy a new mobo, i just sent back to the seller. I bought a new Supply !!

toddmccourt17 · Dec 2, 2018

contact AMD i had the same problem https://www.amd.com/en/support/kb/faq/pa-100

they will send you a bootkit which is pretty much an old cpu which requires an earlier bios. once you boot the pc with the boot kit update the motherboard to the latest bios ken you can add you ryzen chip back in, i should also mention you have to send the boot kit back after use. works great
