XMP - system post in safe mode. Happened once after some time pc off

Hi. My mobo is Asus Z370 Pro Gaming. And rams: Gskill 2x8GB 2133mhz ( XMP 3000mhz ).

Cpu 8700K. When i choose in UEFI first time XMP profile i saved and booted fine to UEFI.

I turn off pc,turn on again after 2 hours, and then, i met screen:

THE SYSTEM HAS POSTED IN SAFE MODE.

This happened just once. Now its booting fine,but i dont know why it booted just once with this message.

This is screen from internet ( not my pc ) ,but the same msg to show:

I tried to reproduce this warning but i am not able to do that. Reverting to standard and then again to XMP save. Turn off pc by power button. But not warning. Any ideas why it happened just once,and still its something wrong?

This occured when pc was off some time , 4 hours . And then. I met users using XMP with the same issue , only after pc was off some time like overnight.

So it not never happen when i turn off pc and immidiately turn on. Only just when pc is off few hours.

Memtest not showing errors also.

Really appreciate it for help. This is my new pc.

If it has only done it once then I would not worry. If it is doing it everytime the PC is switched off then it may be the Cmos battery needs to be reseated or replaced

if you cannot reproduce it dont worry. The Z370 BIOSes are still green and hickups will happen.

Asus mobos are very picky with RAM timings (one of the reasons I would never buy one)

The RAM you are using is on the QVL list ?

I think they are on list.

That my rams:

It happened once after i applied XMP and turned off pc for 2 hours. After 2 hours i boot pc and met that message. Not happened again.

No (page 16) : http://dlcdnet.asus.com/pub/ASUS/mb/LGA1151/TUF_Z370-PRO_GAMING/TUF_Z370-PRO_GAMING_Memory_QVL_report_20170927.pdf?_ga=2.59271471.324849203.1516063526-742818865.1490917776In

I know one rule. Is that working? Yes? Do nothing, and don't even think of doing something.

The big Q is, is your RAM now working at 2133 or XMP ?

Usually, if the Bios reverts to Safe Defaults, it will remain in that RAM Speed mode until you enter Bios again and correct it.

Make sure the Volts are applied properly, 1.35V for DDR4-XMP usually.

My tip, you can try to lower each Voltage to the default value:

those are

0.95 for VCC-IO

1.05 VCC-SA

1.0 PCH

1.0 CPU Standby

the defaults are also listed bottom line on that page in Bios, no need to take notes now ;)

you can safe some temps by doing this. Asus usually applies way too much to stay safe even with the worst of all 8700k.

Asus Ai-Suite does show the RAM speed, you dont need any additional SW to read that value, tho CPUZ is a great help on new systems, so is HWinfo and a few others, the usual suspects.

They are currently working on XMP speed 3000mhz. Yes.

I tried to reproduce this warning but i am not able to do that. Reverting to standard and then again to XMP save. Turn off pc by power button. But not warning. Any ideas why it happened just once,and still its something wrong?

hmmmm, off as in "disconnected from wall" or " only shut down my os"

it shouldnt matter actually but those are 2 different states

Only shutdown system OS. Not from wall. It happened first time when i just shutdown system and turned on again after 4 hours. ( not from wall ). Power cord was still on.

I think they are on list.

So that is a definite yes then ?

It actualy doesnt mean much if they are listed, that is what Asus says themselves.

It is in no way a garanty that your same RAM kit will work in a same modell board.

It only says, one board and one ram kit on their end worked at least once, that's all !

screw the QVL, it's DDR4. If not send it back and stirr up the chain as much as possible to let them know that the guy at the end of the chain, YOU, who pays all bills from all in chain in front of you, gets a non-working product is utmost upset about it.

You dont want me as an unsatisfied customer, you really dont !

If you dont give your untainted feedback nothing ever changes to the better, no, quite the opposite will happen over time.

Hi. So i left my pc off for 12 hours. I booted in morning fine without warning. So its booting fine. Also my question. Ignore that one occurance or its something wrong still?

yes.

The big difference is, depending on setting in Bios, that by default your new board uses FAST BOOT, whereas if you have UNPLUGGED it from 110/230V you force it to do a full boot, which means it does a full self test, ram scrambling and memory detection routines which can take up to 5 min i the config is borderline. All adapter cards, onboard and embedded, get reassigned, etc etc..

DOing a fastboot means, take the old list and table, hope that nothing changed and fire it up.

I HATE THAT ! full BS ! If your PC wont boot, you have to cold boot it to be able to get into Bios, as THAT is the biggest difference that you may encounter. IT WONT LET ME IN BIOS, until you unplug it for 10sec and reconnect, THAT forces the slow boot with the option to enter Bios.

I guess it went into RAM initialisation and failed, then it got stuck, rebooted itself or forced, saw it had a broken boot and went to fail safe. Pretty standard for any misconfigured RAM and boot attempt. The Bios does many things when you boot it up, check the lights on your board what it does when and what light is on when it stops booting, that points you the the root cause usually.

go to bios --> boot settings --> fast boot --> OFF

do a proper boot each time :)

First time when i get that warning i pressed power button from UEFI. But like i said i cant reproduce this issue with the same procedure.:)

It actualy doesnt mean much if they are listed, that is what Asus says themselves.

At least that statement points to how crap Asus are at testing stuff

Yet another reason to avoid their stuff

go to bios --> boot settings --> fast boot --> OFF

In the immortal words of Sweet Brown....I got bronchitis, ain't nobody got time for that!!!! :D:D

Just in case someone missed it.

On a fresh formatted ssd i install Windows 10. When i installed Windows 10 there was a problem with...

1.When i go to windows settings, no matter what i click on system settings it wont opened. SO click and nothing.

2.Problem with web browsers ( Firefox and Chrome ). When i go to some site, and try to download something ( right click save ), browser just hang,and not respond. I had to click X on the browser.

This happens in BOTH Firefox and Chrome, which is why I think it's an issue on Windows' part?

I dont know how but after 2-3 restart now its all fine and working fine. I just ask why that happened? It maybe was related to my rams?

But like i said now its fine. I even tried format again and i installed second time W10 but problem not repeated. Like you think it was related to XMP or just W10 bug?

My computer did the same thing. I clicked on Settings and nothing happened. Then about 5 min later, I closed the blank Settings screen and tried it again and it was fine. My guess is that something was updating in the background?

It's never happened again so I didn't sweat it. But no issues with browser Chrome or FF. Also, do alt-tab through open apps just in case there is a hidden FW popup asking if the program should be let out.

I guess anything is possible, but I can't see your RAM being the cause of this.
