TUF GAMING X670E PLUS POST issues

I start to think i choosed poorly when i switched to ASUS and bought the motherboard in the subject . This motherboard kills me slowly.

Since i bought it, had only problems with it. Particulary with the booting. At power on always had a blue screen, when i entered BIOS and boot manually worked like a charm. I reinstalled Windows, though it would solve my problem, and it was solved for a while (around 2 days), the sistem booted on his own. 

After 2 days i get random POST LEDs, sometimes is the GPU, sometimes the RAM, sometimes is a blue screen that says that some online certificate cannot be checked. After i kill my nerves for 10-15 minutes, power downs and disconnects,  i manage to boot it manually and there is no crashing while gaming. The stability tests are ok. 

I honestly do not know what to do and what could be the problem...

If EXPO elieviates the issue then the memory overclock is unstable. Have you tried EXPO II? This is the default DIMM profile and contains slightly less aggressive sub timings.

Hello @Ciprianus 

Can you clarify what "boot manually" means? Boot is always automated, so what exactly are you doing?

At the moment, it sounds like system instability. Can you confirm whether the behaviour persists at Optimised Defaults without EXPO enabled? What memory kit are you using (part number)?

Hello @Silent_Scone . Thank you for your swift answer. 

By boot manually i reffer to the fact that i enter BIOS and select the drive to be booted(with windows installed). Though it's only one. 

Apparently loading optimized defaults with EXPO disabled managed the sistem to boot on its own.  I tried to shut down a few times and it booted successfuly

kindly find the kind of RAM i use attached, currently at 4800 clock speed because i disabled EXPO. How can i use it at 6000 clock speed though?

Tried this, system posted succesfully. Aparently each time i activated EXPO, it automatically enabled EXPO I, didn't checked this setting till now. 

I hope it stays stable , i will update this post in case something with the stability happens again. 

Thank you, mister !

Ok. Yes, EXPO I is the default profile and the one validated by the memory vendor and ASUS.

Contrary to assumptions, XMP/EXPO doesn't ensure automatic overclocking. Tighter timings or higher frequencies may require manual adjustments for stability. Overclocking cannot be assured due to variance between parts when run outside manufacture specifications. XMP/EXPO success also greatly depends on the processor's Integrated Memory Controller (IMC) capabilities.

XMP/EXPO IThis is the validated board profile. Every time a board is validated with a particular memory kit, the memory vendor and ASUS use this profile to validate the kit for the QVL.

XMP/EXPO II - This is the default DIMM profile from the memory vendor and contains sub-timings stored within the SPD EEPROM of the memory module. 

XMP/EXPO Tweaked - This is the fastest profile and contains various tuned sub-timings and memory parameters.

After 5 days not using the computer, out of nowere, the same windows error popups:

When I try to enter the recovery, it stucks în bsod with the DIMM orange led off. After it passed în the inițial POST test. 

This really starts to be frustrating...
