Question Ryzen 5700 not POSTing on Asus B350-F Gaming

[NightHawkRMX]

I have a PC with the following specs

Ryzen 7 5700
2x8GB Crucial Ballistix Sport 2400
Asus ROG B350-F Gaming
PNY CS1030 1TB NVME
Gigabyte RX9060XT 8GB
CWT 500W 80+ Bronze

This system originally had a Ryzen 7 1700 and I am upgrading it to a 5700, as well as a new GPU. I ensured the BIOS was upgraded to the latest version, version 6232 (Nov 2024) prior to installing the new hardware.

With the Ryzen 7 5700 installed, the fans spin and the PC lights up, but it does not display any signal to monitor. No debug leds illuminate at all. Normally they flash through a cycle when the system is booting, even if everything is working correctly.

I have tried installing both a Ryzen 5 1400 and 3600, both of which work perfectly. System posts and goes into the BIOS.

At this point I was thinking the 5700 was faulty, I did buy it used. It is specifically with the 5700 that the system has issues. However, I then went and tested this Ryzen 7 5700 in another computer with a MSI B350 Gaming Plus, and the system POSTs with the CPU recognized correctly in BIOS.

Unsure what's the problem here. The CPU is working, and it should be supported by this board and BIOS version, it's on the support list specifically.

Just to update, I also tried with 1 stick of ram, and then tried a different EVGA 8GB Stick I had lying around, no change. I have cleared cmos using the pins with power disconnected, also no change.

sounds like you have an accessible test. Take the memory from the system it works with and try it in the board it did not work with at first. remove the memory that's in it and put the memory it's been proved with in - you can test memory compatiblity without having to keep moving the processors around.

Hey there,

If you haven't already, you need to clear CMOS. Check here and follow the instructions. Part 3 is the relevant one for you. You may have to take out the GPU to get at the battery. But, that shouldn't be too much hassle.

Once done, and then on first boot, you should be directed to the bios, and to reconfigure it. It's a different screen than normal boot, so you'll know if the clear CMOS worked by that method. Hopefully that will get you up and running with the newer CPU.

I have tried to clear cmos multiple times, doesn't seem to change anything. I also have moved the ram from the system the CPU worked in over to the Asus motherboard and it does not change anything. I'm using a single stick of ram for testing now.
