Pretty sure, I had this exact problem this weekend and quite literally just seemingly fixed it (see thread below). What I did that has apparently fixed it was: Down-clocked the CPU (via setting the ratio to 30) to run at 3.0 GHz, and define the VCORE max to 1.3V (rather than an AUTO setting). This allowed the machine to be stable enough to make it into Windows. After I got into Windows, downloaded the newest Chipset drivers from AMD, and updated all other Radeon software. Also made sure I was on the AMD balanced power plan option. Incrementally adjusted the CPU ratio (32, then 34, then finally 36) and the VCORE max (1.3V, 1.325V, and then 1.35V) until it was back to stock.

This was really interesting, and I took a look through it all and the various tests. Idle voltage bounces a fair bit, but if I had to guess in CPU-z it would average between 0.3-0.5V, and in Ryzen Master it was about 0.4-0.5V, so it seems to be okay. I suspect you may be right that the Chipset driver update has perhaps solved the problem. EDIT ~ I got the CPU back up to 3.6 GHz with a max V-CORE of 1.35V; so it looks like the AUTO settings and the old Chipset may have been the problem. Everything seems stable currently and hopefully will remain that way (finger's crossed).

So I just got home; Memtest completed (all four passes on 11 tests) with no errors, so it looks like the RAM is fine. That makes sense. Seeing as the memory passed, I just tested your suggestion of reducing the CPU to 3.0GHz and on restart it seemed to lock up on a blank black screen. But after a CMOS reset, and a second attempt where I also manually adjusting the core voltage to 1.3V and it's made it to Windows and booted. So I'm not sure exactly what's going on. Maybe it's hitting a thermal issue? But the temperatures reported by the BIOS as like mid 30's, and even during Memtest topped at I think 57. I'm currently updating the Chipset drivers, and hoping that makes a difference, but we will see I guess. EDIT ~ For posterity's sake, here is how I fixed it. Down-clocked the CPU (via setting the ratio to 30) to run at 3.0GHz, and defined the VCORE max to 1.3V rather than an AUTO setting. This allowed the machine to be stable enough to make it into Windows. After logging into Windows, I downloaded and installed the newest Chipset drivers from AMD, and updated all other Radeon software. I also made sure to be running on the AMD balanced power plan option. Incrementally adjusted the CPU ratio (32, then 34, and finally 36) and the VCORE max (1.3V, 1.325V, 1.35V) until the processor was back to stock speeds. The machine has been happily running for 10 + hours now, and passed some CPU stress tests from OCCT. So I'm fairly confident that everything is back to normal.

I'm still not a home, so I'm not sure if the how Memtest went, so that's still pending. As for speed it's 3600, but I believe in all my removing of parts/BIOS changes etc. the XMP profile is disabled so from memory it's running at 2133. Interesting that you mentioned the 1.3V as a voltage to use, because from memory I am pretty sure that BIOS was reporting the default VCORE to be sitting around 1.4V. Could it be overdrawing and resetting because of that? I ordered the molex converter to just test and see if it makes any stability difference. If it does, I'll replace it with a proper EPS cable.

Hi team,I recently (Wednesday just gone) just built a new machine (using some old parts, GPU and Drives) after moving to the US and my old 2500k finally dying, and it's been running fine for 5 days. However, yesterday I left it on when I went out as I was downloading some steam files, and when I got back it appeared to stuck in a boot loop. Most of the time it makes it past the BIOS splash page and then just black screens and restarts, other times it was throwing a BSOD with various errors (IRQL not less or equal, and PAGE FAULT IN NONPAGED AREA being the ones I can remember). That said, the BSODs seem to have disappeared today.SpecsRyzen 5 3600MSI X570 Gaming plus16 GB G-Skill Ripjaws V Series DDR4MSI RX480 (old part)Corsair Rm550xSamsung 850 Pro 256GB SSD (Boot drive; old part)Some random HDDs for storageTroubleshooting so far Windows Auto-repair (as during the week a number of updates were installed) Fails to complete with the machine often restarting Flashed the newest BIOS to the motherboard.

Fails, can't make it into the USB CMOS reset via removing battery and unplugging machine overnight; also via JBAT1 reset No changes, still looping The motherboard debug LED on the motherboard seems to indicate a CPU error. But what's weird to me is that the machine can happily sit in the BIOS menu with no problems whatsoever, and I would have thought if the CPU was the fault this wouldn't happen. I am currently running Memtest86 just to double check the memory, I know the first pass completed without error, but I had to leave before seeing the other three.My only thought is that I don't have the additional 4-pin CPU connector plugged into the board, and that is causing issues? I have a Molex to 4 pin convertor on the way, but any thoughts/suggestions would be most welcome.Thanks kindly.
