New CPU, No Post (DRAM Led On)

[Broomsticc]

Hi, I recently upgraded my cpu from a Ryzen 7 2700x to a Ryzen 9 3900x and attempted to boot up my PC. But to my surprise all of the leds turned on but there was no display on my monitor. My motherboard is telling me by the DRAM led staying on is that there may be an issue with my ram (4x8gb 3000mhz Corsair Vengence RGB Pro). Could you please help me figure out what the cause may be? Oh and here's my motherboard just in case (gigabyte b450 aorus m). Thank You. {sorry if that was too formal I'm new here}

Have you updated your BIOS?

 

First update your BIOS (with your old CPU as the new one obvi won’t let you into BIOS), and if that doesn’t work try and get it booted with just a single stick of RAM. Or, just try and clear CMOS with the new CPU in then try and boot. Either way though, definitely make sure your on the latest BIOS.

How long ago did you buy the motherboard? It's possible you got it before they started shipping B450 boards with third gen ryzen compatibility out of the box. If so, you'll need to do a BIOS update to make it work with your new CPU. Just put the old CPU back in and update to the newest BIOS available and see if that fixes anything.

 

Unless of course you already updated the BIOS in which case I don't know what's going on. Clearing CMOS is a good place to start if it doesn't work after a BIOS update though

Thanks for the reply. I bought this motherboard late 2019 and the specs tell me that it is ryzen 3000 series compatible. But the the thing about the old processor...well, I may have bent a few pins.

Thanks for replying. Sadly I've tried all of my ram sticks one by one with no boot. Even worse I may have bent three pins on my old cpu and my pc wont even turn on with it in. Even if I somehow made it work I'm pretty sure my mobo is on the latest bios.

Are you sure it’s on the latest bios?

 

Also, you can carefully bend those back...

 

Reset CMOS. That’s really all I can say at this point.

Will do. Thanks again.
