Hello All,

I have a Asrock b450m pro4 and was running this with a ryzen 1600x stable for many months. I then decided to upgrade to a ryzen 3600 and now experiencing random bios resets after I shutdown the computer or leave it off overnight. Never had this problem with the 1600x. I hate having to go back in the bios and changing the fan curve and ram settings over and over after the bios resets. Tried replacing the cmos battery but that didn't solve the issue. Leaving the ram speed at default didn't help. Also I am on the lasted bios of 3.90 and have all the lastest Amd chipset and graphics drivers installed. Went back to the ryzen 1600x and the bios reset issues disappears. Did anyone ever figure out the fix for this?

I had a similar problem with a different CPU. Which could be solved with better cooling.

NUN: Waste heat from the CPU down, fan on the case (back) pulls out. Air is blown in at the front of the case. And cool the RAM.

bios resets indicate
the pc is failing memory training on cold boot and then resetting bios

check what memory timings your using

Did anyone figure out the fix this just happened to me. My timing was off because I forgot to set the xmp profile but I?m not sure if it was the end all be all fix.
