XMP Profile causes M.2 SSD to not be in boot list

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Every time I try to set XMP profile to bring my RAM to its rated 2666 MHz speed it causes my M.2 SSD to leave the boot list. The SSD is still visible under under Storage Configuration. I have to reset CMOS to get my system to boot again because it won't boot even after setting to default. When i set it to default after trying XMP the SSD does show up in boot list, but still won't boot. I have double checked the timings XMP is setting but I'm not 100% sure I am checking the right things.

Motherboard: X370 Killer SLI/AC
Processor: AMD Ryzen 5 1600
Graphics: XFX Radeon RX 580 Black Edition GTS 8GB GDDR5
Memory: Corsair Vengeance 2x16GB 2666MHz 16-18-18-35
SSD: Plextor 256GB M.2 NVMe SSD

	I have solved this myself. I set the XMP profile and system did not boot as normal. Then I unplugged the SSD, rebooted the system, and re-plugged in the SSD. The system booted to windows after that. It seems to be stable, because I have run several benchmarks and Cinebench without any problems.
