[SOLVED] Asus rog strix X470 F gaming boot issues

[Fragiskos Tsi]

Hello there
After 3 months since i bought my new pc suddenly i got boot problems, for some reason it doesn’t even post unless i change my ram speed up to 2666mhz and it was running perfectly until now at 3200mhz (A2-B2). Also the case fans rpm changed, by the time my issue started my pc become much more quiet whim using it and i didnt do any bios or windows updates by that time. It used to work by default a little high RPM, dont know if this is an issue or not.
Now im running the latest bios version, also i tried clean install of windows, drivers ect. but nothing really changed.
BIOS settings are all set to AUTO except RAM speed(2133-set to 3200).
The orange RAM led keeps ON every time im trying to boot above 2666 mhz. Also i tried CMOS reset.
My ram dimms on another PC worked at 3200mhz using XMP profile, i wasnt very happy that they worked to be honest because why dont they work on mine?
Anyway tomorrow im gonna test another memory to make sure its not RAM problem.
What do you suggest me to do? Should i change any option in bios?

Make sure you aren't just changing RAM speeds. You need to enable XMP.

On my asus mobo there is no option for XMP but DOCP instead. Ive tried resetting bios and enable DOCP which set speed to 3200mhz.
The results are no post even with this option.

Something's not right. Waa this RAM bought as a 2x8gb kit?

Now im trying with brand new g.skill tridentZ rgb 2x8gb A2 and B2 slots. Default settings on bios and boots normaly, by activating DOCP i have the same results. 1st attempt i get RAM error led but in 2nd i have red light cpu. For now im getting red light cpu instead of ram. Im really comfused.

Hey Im having exact problem.. with flare x 3200 and rzyen 2700x.
Iv tried every single thing for 5 6 days..
And I'm 100% sure that we need to revert back bios version.
And the chances are not highest for smooth revert... Things can happen.
Second problem is Ur CPU... cause that bios version downgrade where MB and Ram is stable is old i think the last one for 1000/2000 series.
You can check here lots of us with this MB had lots of problems and u might ask for best bios version for your CPU.
