Z270F can't be shut down completely when holding down POWER button

[harry1511]

I recently upgrade my PC with Z270F and KBL 7700K. I notice that when I need to shut down my computer with the physical POWER button on my chassis (in case I get BSOD or frozen), holding it down will turn off the system, but then in a split second the system start up again. If I release the button, the system is restarted. However, if I keep holding the button even longer, it will shut down eventually, but it is annoying because even holding the button longer, the fans and light inside the case already turn on briefly before they actually shut down.

I checked the connection, I have connected the cable correctly according to the manual. In the BIOS, I tried to hunt down the power management option so I can change it, but it seems only affect in case the power failure. I am still on stock BIOS (0505 I believe), should I update my BIOS? I heard the newest version give some high voltage when using XMP profile. Everything else is on stock atm.

Any idea?

Thanks.

RST is only needed if you have a RAID array, I don't know if that is causing the issue or not, holding the power button to shutdown is only needed in extreme cases so even if this is the case as long as your system is stable it would not be an issue
I only see this behavior when I am tuning memory timings out of spec (overclocking) and the system won't boot which is normal behavior

What Chino is saying is if you are running all default settings you should not have freezes or bsod, if you have these symptoms at default try using only one stick of memory to see if that stops this and then install a second module and so on until all four modules are installed
What is the exact memory kit you are using, model number?

Not really true. Intel RST benefits for single (SSD) drive too.

"Can Intel RST assist me with single drives too?
Through AHCI, storage performance is improved with Native Command Queuing (NCQ). AHCI also delivers longer battery life with Link Power Management (LPM), which can reduce the power consumption of the chipset and Serial ATA (SATA) hard drive."

I've also tested on my system, having significant performance increase with Intel RST vs the default Microsoft driver. Here's the benchmark:

Tested with Crucial MX100 512 GB SSD on Windows 10 Pro 64bit Creator Update.

Yeah, I wanna see some number too. :))

Added benchmark pics. See my previous post: https://rog.asus.com/forum/showthread.php?93186-Z270F-can-t-be-shut-down-completely-when-holding-dow...

Thanks for reply, my system is stable as far as I can tell, no freezes or bsod with stock settings. I also ran memtest and no error after about 3 hours with 2 passes. As for RST, yeah I don't have RAID setup, thinking about uninstalling it too, but it doesn't seem to hurt the performance.

So far with stock settings, everything else is fine, I guess I can ignore this small annoying thing if it doesn't hurt my system. On the other hand, I tried to overclock my RAM with XMP profile last weekend, but couldn't make the system POST at all. I tweaked the VCCIO and SA voltage to about 1.25V, but couldn't get it to POST. Any idea?

The RAM I have is G.SKILL 32GB Ripjaws V Series DDR4 PC4-25600 3200MHz (Model F4-3200C16D-32GVK)

Try uninstalling the Intel RST software to see if it solves the boot problem.

Will try it tonight. Besides, any tip for tweaking XMP profile I posted earlier?

Tweak your SA & VCCIO voltages to stabilize your RAM. You can follow these guidelines:

Follow these guidelines.

DDR4 frequency range	Required CPU VCCIO Voltage range	Required CPU System Agent Voltage range
DDR4-2133 ~ DDR4-2800	1.05V ~ 1.15V	1.05V ~ 1.15V
DDR4-2800 ~ DDR4-3600	1.10V ~ 1.25V	1.10V ~ 1.30V
DDR4-3600 ~ DDR4-4266	1.15V ~ 1.30V	1.20V ~ 1.35V
