Problem installing Ryzen 7 5800X3D

Components:
MB: Msi X570 A-Pro
GPU: Msi RX 6700 XT 12GB GDDR6
PSU: EVGA 850 G3
RAM: G. SKILL Ripjaws V Series 32GB (2 x 16GB)
Previous CPU: Ryzen 7 2700 Pinnacle Ridge (Zen+)
New CPU: Ryzen 7 5800X3D

 

So I installed the 5800X3D. Cleared the CMOS by taking the battery out for 10 or so minutes and putting it back in. Turned the PC on but it wouldn't post and the CPU EZ Debug light on the Msi motherboard was showing.

 

After some research I updated the BIOS by copying the update file to a pendrive, renaming it to MSI.ROM, sticking it in the appropriate USB port, and pressing the bios flash button right above the USB port. The update seems to have gone smoothly - slow blinking for a few seconds then rapid blinking for a few minutes before it restarted itself. I shut it off, left it unplugged for a while, and when I turn it back on the CPU EZ Debug light is off but the PC still won't post and now 2 other EZ Debug lights are on: the BOOT light and the VGA light. I've removed and reinstalled all components and it still shows the same thing: VGA and BOOT lights on.

 

Afterwards, following someone's suggestion, I went back and reinstalled the 2700 and it posted and was able to get into Windows. I reset to go into the BIOS and make sure the right update was installed. It was, but I installed via M-Flash anyways just to make sure. Everything went fine again with the 2700 so I removed it and reinstalled the 5800X3D again and I still get the same thing: CPU EZ Debug light comes on for a few seconds before it goes off and the BOOT and VGA lights come on and the PC fails to post.

 

Help.

You’ve done some solid troubleshooting, but here are a few more things to check:

  1. BIOS Version – Confirm you're using the correct motherboard BIOS version that supports the 5800X3D.



    Some users have had success with an older version rather than the latest one.
  2. Boot Mode – Switching from UEFI to CSM in the BIOS has resolved boot issues for some people.
  3. GPU Troubleshooting – Since the VGA debug light is on, try reseating the GPU or testing a different one if possible.
  4. Power Connections – Ensure both the 8-pin and 4-pin CPU power connectors are properly connected.
  5. Potential CPU Issue – If your old CPU works fine but the new one won’t post, the 5800X3D may be faulty. Some users have had to replace theirs.

Okay originally it seems you had the wrong BIOS installed that didn't recognize your new 5000 series CPU.

 

After you updated the BIOS now the new CPU is recognized but you are having issues with your GPU.

 

When you power up your PC during POST, BIOS starts checking and testing the Motherboard and its hardware.

 

When you see the Motherboard's CPU LED Light up and then turned off means that the CPU passed the BIOS test during POST and went on to check the RAM and GPU and Windows drive.

 

Your Ram seemed to have passed the BIOS test since the RAM Trouble LED light didn't light up and stay on. But that doesn't mean it is compatible with your new CPU though.

 

Check your Motherboard's QVL RAM MEMORY List for the 5000 series CPU and see if your RAM you have currently installed is compatible with the new CPU processor.

 

After BIOS test your RAM it then goes on to test your GPU card/IGPU installed.

 

Do you have your Monitor connected to your GPU card or the Motherboard (IGPU video ports)?

 

Make sure you have the PSU/GPU Power cable connected if applicable.

 

If it is try connecting your Monitor to your Motherboard's Video output port and see if it boots up normally while disconnecting your Monitor cables from the AMD GPU Card. If it does that might indicate an issue with your AMD GPU Card.

 

You should keep BIOS in UEFI mode, if you have Windows 11 installed, since your AMD GPU card should be UEFI Compatible.

 

NOTE: Since your last CPU was not a APU (Processor with a IGPU) it is possible that in BIOS it made your IGPU on the new 5000 series CPU the Main Display adapter and if your Monitor is not connected to the IGPU Motherboard's video output ports  it can cause that GPU Trouble LED to light up since BIOS doesn't see anything connected to the IGPU.

Good suggestions.  I bet the default video output is to the motherboard (if there is an HDMI or DP port on the motherboard).  I would certainly remove the CMOS battery, disconnect the power cord to the PSU and leave them disconnected for several minutes to clear the CMOS settings that might have carried over from previous BIOS updates.


As Albert Einstein said, "I could have done so much more with a Big Al's Computer!".

I checked the MSI website and yeah, my RAM does not appear in the compatibility chart for the X570 motherboard with a series 5000 CPU. I ordered some new RAM that does appear in the compatibility table and it should arrive tomorrow. I'll comment back with results.

you can always use that RAM as a backup in case of an emergency if your problem wasn't due to Ram incompatibility.

 

You could also have check the Ram Manufacturer's QVL List to see if it was compatible and also AMD Ryzen RAM Memory list.

 

But normally, from past experience here at AMD Forums, if you have incompatible RAM either the CPU  or DRAM trouble led light will stay on or both will stay on at the same time.

 

But since, according to your post, the Dram light never stayed on does indicate it passed the BIOS Test for the RAM you have installed.

 

But it is best to get QVL List RAM for your new processor to avoid any incompatibility issues.

I was just looking at the CPU support for this motherboard and only saw GEN 2 and GEN 3 CPU's.  I'm guessing that you may have more problems other than GPU and RAM compatibility with the 5800X3D CPU.

I would actually short out the JBAT jumper as opposed to just removing the CMOS battery and see if that fixes your issue.

I've shorted those jumpers in the past, but I still wondered if it cleared out all previous settings if you left the CMOS battery installed.  I know they will go away without any power to retain them in memory.


As Albert Einstein said, "I could have done so much more with a Big Al's Computer!".

Did a little more digging and the motherboard is compatible with the 5800X3D CPU.  However this is the BIOS update that I found 7C37vHG.zip on MSI's compatibility list.

I give up. I cant get my PC to work now even with the old CPU. I think I may have damaged soemething with all this building, taking apart and putting back together. I cant even get it to update the BIOS using a pendrive and the flash buttin on the MB. I think I'm just going to buy a new full combo of MB + CPU + RAM. Any recommendations that will go well with my current GPU and will allow for future upgrades?

Woooooo! Nevermind. Was able to get it to work with the pre-upgrade / pre-problem components. I'm returning the 5800X3D and just forgetting about upgrading for now until I can upgrade to a more modern AM5 Socket Board and CPU. Any suggestions, whether AM5 or otherwise, that will go well with my current GPU will still be greatly appreciated.

It is possible that the Ryzen 7 5800X3D was at fault.  I feel like these haven't really been around for a while and were essentially replaced by the 5700X3D which is now also hardly available.  Not sure where you were able to buy a 5800X3D, but it is likely not a new production model.  Most of what is out there now for AM4 are the XT models like the 5800XT and 5900XT.

 

On the other hand, the issues you are experiencing seem to be common for that motherboard.

Well, I would focus on an AM5 CPU that's on sale.  Your GPU (RX 6700 XT) isn't top of the line, and I guess it really depends on your priorities for either gaming or workstation usage.  Newegg offers combo deals, with a Ryzen 9000 series CPU, a compatible AM5 motherboard and memory (go for 32 GB, not just 16 GB).  From my perspective, I usually just build another computer and keep the old one operational.  Maybe that's why I tend to collect so many machines - I have eleven gaming computers on my LAN.  If you decide to go for a higher-end GPU, I think either the 7900 XT or the 9070 XT is your best bet.  Find one on sale though.  Don't go paying over $800 for one.

I used to purchase products in the past with Newegg. But now since it is fully owned by a Chinese company their return and warranties aren't as good as before.

 

But I have to give Newegg credit for when my HDD I bought was pirated from the front of my condo door.  I sent Newegg a Police Report of the stolen delivered package plus the fact the package was clearly labled Newegg.com thus easily advertising I had some computer hardware in the box.

 

But Newegg refunded me the full purchase price after I uploaded my police report. So I do give Newegg Customer Service a good rating for that specific incident.
