Asus B650E-F ROG STRIX no boot, no POST, orange DRAM light up

[entropy__]

Hi all,

I recently upgraded my computer, new CPU, motherboard and RAM. I had a initially made my build with a MSI motherboard, everything went well for a while, and 2 weeks later it didn't restart, showing CPU red and DRAM orange LEDs. I tried everything I could think of, and ended up thinking it was a motherboard issue and sent it back to be replaced with an Asus ROG STRIX B650E-F motherboard.

I turned the mobo on before inserting anything just to check if it worked, the RGB on the ROG logo light up properly. Then I setup everything with the CPU and RAM installed. When I turned it on, it was displaying a orange light on the DRAM LED.
There, I tried many things:
- only put on RAM stick on the A2 slot and wait 5 minutes for the boot.
- only one RAM stick but on the B2 slot and wait for 5 minutes
- flashed the BIOS to latest version
- Clear CMOS with a jumper (waiting 5-10 seconds)

None of the above worked.
I then tried my RAM stick on a friends' mobo, where they were both properly recognized and working.

At one point, I removed all the RAM sticks, performed a CMOS reset with a jumper, put back one RAM stick in B2 slot, and turned it on. After a few seconds, the orange light turned off and the VGA white light turned on, because I didn't have a screen attached. Then a few seconds later it went back to only the RAM orange LED light up, without me doing anything.

I know my RAM sticks are not listed on the supported RAM but I was hoping it could still manage to function, at least to get past POST and let me into bios settings... maybe that's the issue?

Now, the RGB lights of the ROG logo aren't even turning on, which scares me because it wasn't like this at first. I still have that orange LED coming up every time...
I don't know what to do... anybody have any idea?

Hi @entropy__ , I am sorry to hear about your troubles. As per your board's documentation when trying with only 1 DIMM stick, it needs to go into A2 slot. See page 1-5 page of your board's user guide for details.

Since you have tried few things, can you please give the following a try as well and see if this helps.

• Make sure you have the latest BIOS flashed.
• Now disconnect the POWER Cable to your PSU and using the CLRTC pins, clear your CMOS. See https://www.asus.com/support/faq/1040820/ page for details. You simply need to short circuit these two PINS which you can do it easily with a screw driver. Please make sure that the power cable is NOT connected to your PSU so you do not damage anything when clearing the CMOS.
• Now install only 1 memory stick in your A2 slot.
• Make sure you have a keyboard connected
• Make sure you have a monitor connected to the HDMI Rear IO port. There is no need to have any graphics card installed at this point since we would you to get into a working state first.
• Now connect the power cable to PSU and turn on your computer.

Let us know if you are able to get past the DRAM light and possibly able to see BIOS screen or not. I hope this helps you move forward. Good luck!

Hi @entropy__ 

Please remove the CPU and inspect the pin-pad and socket. Please also note that on initial startup the system will perform memory training which can take up to 3 to 5 minutes.

As you have already tried the user's suggestions and debugging in various ways, and the board has already been replaced following the initial issue, I would suggest taking the system and CPU to a system integrator to confirm whether the CPU has failed.

Thanks both of you for your replies, I went to a computer repair store, they tried the CPU on another board and it seems that the CPU is dead. The guy at the store told me it was a recurrent issue with Ryzen 7 CPUs, so I guess I just had no luck there.

Anyway, thanks everyone!
