Has anyone been experiencing instability until a reboot? I've noticed this since BIOS 6401 (I'm now on 6903). I don't want to go back to an older BIOS as 6401 and higher seems to have fixed the PWM fan control issue.
What happens is Intel Burn Test shows instability after 5-10 minutes, Witcher 3 and Resident Evil 2 crashes to desktop without any errors. But then after a reboot, it'll be 100% stable all day.
For example, when Witcher 3 crashes to desktop I can start up Witcher 3 again and it'll crash after 5-10 minutes. I can keep doing this and it'll keep crashing unless I reboot. After rebooting, it'll never crash. Sometimes it takes two reboots. Same with IBT.
This is all on stock, nothing overclocked.
Anyone seen this?
Another annoying issue I've having since I've owned the board (1.5 years) is the M.2 PCIe speed. It'll sometimes be in x1 mode. I notice this when I transfer large files as my speed is limited to around 700 MB/s. I open up Crystal Disk Info and it'll show x1. If I reboot, it'll go to x4 and my speeds go up to 1800 MB/s (my SSD rated speed).
I don't think the M.2 speed is related to the instability. What I mean by this, the crashing happens whether my M.2 is x1 or x4.
