Replacing my Ryzen 5 1600 with a 3700x and having issues

Schweet

Replacing my Ryzen 5 1600 with a 3700X that I bought from a friend, who was also helping me install it (he's more knowledgeable than I).  With the 3700x in the CPU and DRAM ez debug lights come on and it doesn't boot.  Swapping back it works fine.  We confirmed (via MSI's website) and updated to the bios to the latest version and everything I can find says it should work.  

 

Tried:

* reseating the 3700x
* booting with a single ram stick, trying both by themselves
* reset the bios with the JBAT1

 

This happened a few days ago so there's probably a few more things we tried that I'm not remembering too.  Any suggestions on what might be happening and how to resolve it?

 

Specs:

*OS: windows 10 64bit

*MSI B350 gaming pro MB

*RTX 2080

*PSU: corsair cx550m 550w 80+ bronze

*RAM: crucial ballistix sport Ltd 16gb (2x8) ddr4

Any missing/bent pins on the 3700x?

Does the BIOS confirm that you have successfully updated?

From what I read on MSI's website, the 3700X requires a specific BIOS, not necessarily the latest available. So, you may have to download and flash a new BIOS for the 3700X to run adequately on that motherboard.

The BIOS file is named 7A39v2N.zip and is available on MSI's website.

Good luck !

No, checked multiple times before and after installing it.

Welcome to the Forums!

 

Does the 3700X CPU work in a different motherboard?

Yes, my friend just removed it from his PC to upgrade his PC.

Yes.  Not only does it look wildly different from the previous version, it says the new version name on it.

We had seen that as well, and while that isn't the latest version I would assume they wouldn't remove cpu compatibility with a newer version of the bios.  We did try flashing to that version of the bios afterwards as well and it will not let you revert to an older bios version.

Support wouldn't be removed for a CPU as popular as the 3700X.

 

Have you tried booting with the minimal amount of hardware possible? So just CPU, RAM, mobo, GPU, PSU - no SSD, no peripherals attached, just seeing if you can get to the BIOS.

newest bios on msi b350 typically removes 3000 series support sadly.

They did for some models because the memory capacity for the BIOS was limited. So, for supporting newer CPUs they had to drop some older models.

If this didn't work, you'll have to test your CPU in another computer to see if it is working properly. Even if it was working before, there may be some damage that happened along the way like a bent pin or static electricity discharge.

Hope that helps.
