Restarting once during startup with X.M.P.
Restarting once during startup with X.M.P.
Hi!
I’m dealing with an Asus Z170M-PLUS MoBo setup. It has an i5-6600 CPU without K, and 16 GB of Corsair CMK16GX4M2B3000C15 Vengeance LPX RAM at 3000 MHz. The PC boots fine without XMP, but to hit the 3000 MHz for the RAM I need to enable XMP, which then causes some odd behavior. When I power on, everything works normally—lights and fans operate as expected—but after a few seconds (3-5), the system shuts down completely, with fans and lights cutting off. After a couple of seconds, it restarts, displays the ASUS boot logo, and launches Windows 10. This is quite frustrating.
If I restart from Windows 10, instead of simply rebooting, the PC powers off again before coming back on and starting the OS.
Could you help me fix this?
I double-checked everything during assembly—every component seems compatible according to ASUS guidelines. The RAM timings and voltage look correct, so I’m sure it’s something else.
Also, I used the built-in “EZ tuning” feature for these changes, since I don’t really enjoy overclocking.

For optimal performance when using 3000 and higher DRAM, it's usually necessary to slightly increase the CPU overclocking. This is because the CPU might not be able to handle the increased DRAM voltage, so adjusting the VCCIO voltage around the same level can help.
For optimal performance when using 3000 and higher DRAM, it's common to slightly increase the CPU overclocking. This is because the CPU might not be able to fully optimize itself, so adjusting the DRAM voltage by around +0.05 and keeping the VCCIO voltage similar can help improve stability.
