First thing to do: Update the BIOS, or UEFI, as it’s called ‘nowadays. Of course that didn’t help. Also, the changelog wasn’t very helpful (“improving stability”), thanks, ASUS!<\/p>\n
So I ventured out and and did some research on overclocking and memory timing. Turns out that Intel invented\u00a0XMP<\/a> (Extreme Memory Profile). Basically, it’s timing data stored on the memory bar, read and used by the BIOS\/UEFI. AMD didn’t want to pay the license fee, so they called their version AMP. ASUS, the mainboard manufacturer, called its implementation of AMP D.O.C.P.<\/a> (Direct Over Clock Profile).<\/p>\n Full of hope, I turned on D.O.C.P. It set the timing data to the suggested values from this document<\/a>. It didn’t help. Guess when I bought the new gear:<\/p>\n The crashes have absolutely nothing to do with CPU load or temperature, quite the opposite. Mostly, they happen during the night, after<\/em> backup \ud83d\ude41<\/p>\n “What the hell”, I figured, and bought another memory kit. This time\u00a016GB G.Skill Flare X for only\u00a0\u20ac 197,46. After that the box ran for whopping 5 days without a crash, yay! It still crashed, though. This time I didn’t have X running and saw a kernel message that PID 1 (systemd) was stuck: “Soft lockup: CPU#3 stuck for 23s” (or similar). As always, I could only recover the box by hardware reset.<\/p>\n So today (2017\/11\/24) I updated to the latest BIOS\/UEFI (PRIME-X370-PRO-ASUS-3203.CAP) and down-clocked the memory to 2199 or 2133Mhz, don’t remember the exact number. Let’s see how that turns out!<\/p>\n [To be (dis)-continued…]<\/p>\n","protected":false},"excerpt":{"rendered":" Introduction Since the arrival of my new\u00a0Ryzen system\u00a0I had problems with\u00a0random crashes.\u00a0Seems it’s a memory timing problem, at least that’s what Google suggests.
