I'm seeing the same bsod 124 error code with a new build on a asus z87 pro motherboard. The full spec is: ASUS Z87-PRO s1150 Z87 MoBo Intel Core i7 4770K S1150 Samsung 250GB 840 SSD Basic Corsair 16GB 2x8GB CMZ16GX3M2A1866C10R Corsair TX650V2 PSU I haven't had time to start troubleshooting yet but it's interesting that you have the same issue. Have you managed to resolve this? Googling the 124 error code, a lot of people suggest increasing the vcore? I haven't attempted any overclocking so would have hoped the default settings would be fine? Any advice most welcome.
