XMP causes fail?

DanteGTX · May 17, 2017

Hello everyone
After building my new pc i was dissapointed seeing ram working on lower speed, 2133 instead of 2400.
After reading forums i've informed about xmp settings in BIOS.
Then i set xpm profile everything and everything went good until next day. PC booted with this message

I've pressed f1 then without changing anything pc normally boots up, but same problem exist next day.
Then i decided to update bios but same next day but interesting thing is that appears only morning.

Mobo: ASUS PRIME H270M-PLUS
RAM: CORSAIR Vengeance LPX 8GB 2400
CPU: I5 7500

DanteGTX :

Overclocked CPU?

Of course not, its not even K CPU

That's interesting. That setup supports 2400 natively, so there should be no need to even turn XMP. It should be plug'n'play. Mind posting screenshot from CPU-Z, tab SPD?

Cpuz shows 1076mhz without xpm but with xmp its 1200

DRagor · May 17, 2017

Not even single JEDEC profile that shows 1200 MHz?

Ok, so XMP needs to be used.
Try this: reset CMOS. At next boot, go to BIOS, select Load Optimized Defaults (F5), Save and Exit. After reboot go to BIOS again, turn XMP on, Save and Exit.
If that won't help, you will probably need to play with ram voltages.

Also the reason problem only appears at morning could be that PSU when starting cold cannot keep voltages in correct margin. If you have access to another PSU, you could swap it and check if problem appears with another unit.

I dont think its can caused by psu cuz xmp not changing voltages its 1.2 on both.
How to reset cmos?

Manual page 1-6, point 12.
"Clear RTC RAM (2-pin CLRTC)
This header allows you to clear the CMOS RTC RAM data of
the system setup information such as date, time, and system
passwords.
To erase the RTC RAM:
1. Turn OFF the computer and unplug the power cord.
2. Use a metal object such as a screwdriver to short the two
pins.
3. Plug the power cord and turn ON the computer.
4. Hold down the <Del> key during the boot process and enter BIOS setup to re-enter data.

If the steps above do not help, remove the onboard battery and short the
two pins again to clear the CMOS RTC RAM data. After clearing the CMOS,
reinstall the battery."

Ty for help ive read about removing battery and holding power button will do the job, is that right?

DRagor · May 17, 2017

Yes, usually it does the trick. If it does not, you simply take the battery out for longer time.

DanteGTX · May 17, 2017

Ill try it tommorow

DanteGTX · May 18, 2017
