Memory instability. The applied settings arent passing training, so the subsequent restarts are the system attempting to do so. With XMP 1 applied, try using Maximus Tweak Mode 1. You may need to tune VCSSA depending on the CPU and memory kit. Â*

Im suddenly having issues with restarting my PC about half the time. Doesn't seem to happen when booting from shut down, only restarts. I've been running the same bios settings for about a year without issue. Any ideas what's causing this?

Hard resets can be a sign of memory instability, test your applied settings with a memory stress test such as HCI Mem test pro or Karhu ram test.

You may also wish to check your event log to see if the system is logging stop codes, and test the system with a different power supply if possible.

So I seemed to have fixed it. I had already done substantial memory stability test before but thanks for the suggestions. It seems my bios had somehow gotten corrupted or something weird with it. I went into bios and loaded optimized defaults. Then I loaded windows and downloaded the latest bios (which is what I was running before) and put it on a freshly formatted USB. I then loaded bios and flashed the bios. I reentered all my overclock settings and it's been running flawlessly ever since. I've done multiple restarts and cold boots with no resets. I'm wondering if something happened when I originally flashed this bios and it didn't quite flash properly or something. Very odd but seems to be working good now so happy about that.

How do I test for memory instability more? I've ran memtest hci for 1000% with no errors. Ive ran prime and occt without crashes and I'm not getting crashes when I use the computer. No resets since I flashed new bios. I'm running the xmp profile on the ram 32gb@4000mhz with io 1.25 sa1.25
