I recently purchased the Asrock X99 Extreme4/3.1 with the compatible memory Corsair CMD16GX4M4B3000C15 16gb.
When i go into BIOS and try to set the DRAM to 3000mhz the computer fails to boot and will cycle from bios/black screen to power down and then power back up.
im currently running the following.
MOBO: Asrock X99 Extreme4/3.1
CPU: i7 5820k
GPU: R9 280x
