Welcome to the ROG Forums.
The 124 error is usually QPI/DRAM voltage, either too high or to low.
I say usually because there are other situations that will throw the 124 error at times.
Re-boot, hold the Delete key to enter Bios Setup.
Go to last page, select load Defaults.
Save and Exit, let comp boot to Windows.
Open TurboV (with advanced setting showing) and Real Temp on the desktop.
Also open CPU-Z twice, once with the CPU tab displayed and once with the Memory tab displayed.
Take a screenshot. Crop it, so it's easy to read.
Post the screenshot here.
