X370 Gaming-ITX/ac, R5 5500 support

Great news, I got it working. I'm not 100% sure what happened but this is my theory. I probably installed a little too much of my old Arctic Silver II when I installed the proc. I think it leaked over and allowed a couple of the pins to conduct to each other.

I pulled the proc before I posted and cleaned it up but it didn't work. The brush I used was a little too stiff and I think I bent a couple pins. Thankfully they didn't break off.

I decided to upgrade my 1600X system so I put that processor in place of the 5500 and the system started right up. I took a soft toothbrush and a bunch of isopropyl alcohol and really cleaned the pins. I inspected the pins to make sure there wasn't a hint of silver between them. Put the proc back in and it started right up.

Thanks for the help!

Thank you. I've ordered another power supply, it should be here in a few days. I decided to upgrade my 1600X as well so I'll have that processor available to test with too.

I'll report back after my other hardware arrives. Hopefully with good news!

I ran into an interesting situation.

After a couple months of running without issue, the PC wouldn't turn back on.

Here's what happened: Just before Thanksgiving, the PC was powered off including the power supply.

Later we tried to power it back on, the fans spin up and nothing else happens. I removed ram/video card/ etc. I got down to just bare bones and it's all the same. Hit the power button, the fans come on and run, the ethernet light will flash but then nothing else happens. After holding the power button, the system will not power off either, I have to use the power supply switch to get it to shut off.

I hooked up a PC speaker to the speaker connection hoping for some beep codes and it never makes a sound.

Thoughts?

Update, with my 1600X I was able to get the BIOS flashed to 7.40 and the 5500 now works and I have a Happy Son!

Thanks for the help!

wino pretty much hit the nail on the head. Your best bet would be to take your
system in to a tech store/specialist and have them update the BIOS for you. Otherwise
you will need a CPU that is supported by version 7.0 to perform the update safely.
