Excellent Seizantherealone :p and glad you have it sorted. As you have found, there is more than one method to update Bios and EZ Flash from within Bios has worked.
Others cannot enter Bios so...

Yes you need to flash your Bios to latest version 6903 and your chipset driver.
It is simple providing you follow these steps carefully.

Refer to your MB manual on page 2-13 for USB Flashback....

Qcode AE is a Legacy Boot event indicating an error with your SSD or HDD or an improper Bios configuration with your drives priority. So you may in fact have two issues. There is a difference...

During POST (Power on self test) your system is interrogated.

POST begins by checking the BIOS chip and then tests CMOS RAM. If the POST does not detect a battery failure, it then continues to...

Hi Kien18 :) and Welcome to ROG


Qcode AA means the system has transitioned to ACPI mode (Advanced Configuration and Power Interface) and therefore handed over to the OS.

Interesting, It may not be a selectable feature in Bios but I have no problem using my USB3 case sockets to charge devices ( Vape Mod and iphone) when system is powered down. I am using Crosshair VI...

It does make it difficult when Post does not complete and no access to Bios. :(

G.Skill F4-3600C18D-16GTZRX may not be listed on the QVL however that may just mean the MB QVL was not up to date....

Hi raviharshil27 :)

Qcode 8 is a problematic code in so much as it's not documented. It is however quite common and many have found it to be a Memory issue. Your Qcode sequence seems to indicate...

To help understand the MB naming convention, please review this thread: https://rog.asus.com/forum/showthread.php?100962-Motherboard-Name-labeling :p

Never a "silly" question sgmfish :).

The Prime X470-Pro mobo is a completely different motherboard to the Crosshair VII Hero. IMO Crosshair VII Hero is a better board for Overclocking. Prime...

What frequencies and size of RAM you use is dependent on the IMC (Integrated Memory Controller) on the chip and not the MB (if the board officially supports it). High frequency RAM say at 4000MHz and...

@gorpo
That famous quote by the STILT re: the QVL is referring to the RAM manufacturers QVL and not the MB manufacturers QVL.
The benefit of the MB QVL as a reference to what has been tested and...

Even micro coding devs have had issue with Ryzen which as you know is picky with RAM. Only now with Ryzen Gen 2 have we seen better RAM matching with AGESA.
Of all the Ryzen builds so far, not one...

There is no listing for a 32GB (2X16) F4-3200C 16Q-32GTZRX on the MB QVL so they have not been tested. Not to say they will not work however rather demanding on the IMC.

As they are OC RAM (and if...

Your Welcome Mordorr :)

After a while and if your interested enough, your Bios becomes second nature. For some it is frustrating and mainly because of unreal expectation. Many try to MAX out an...

There are many avid Overclockers and some of the best are here on this Forum. How you go about developing your Overclocking skills is to do the hard yards and research.
No one is going to give you...

OMG where to start. OK so gone are the days of good old school OC.

The AM4 platform is far superior to LGA775 and a 2 core platform. You are also dealing with much faster DDR4 RAM frequencies....

1.5V with DDR4 RAM is excessive. Max is 1.35v for longevity. Keep an eye on their temperatures.

Hi Zefram :) Not much help I know however.

You may have a Latency mismatch by combining two different kits especially using 32GB @3600MHz with all slots occupied. If it continues and you can't...

Reason why no one has answered is probably that your system is ROCK SOLID. So what more can be said than congrats.

1. The Stilt's safe 3333 preset for B Die RAM is irrelevant for what you have...

A simple solution, go back to 1002. Most find stability difficult to attain at 4000MHz. It's not the Bios but the use of it.

Thank you and glad you have it sorted. An addition to my rep would be most appreciated.

Bios flash is done using the rear I/O panel and no need to be in Bios.
Download the Bios file from ASUS Support to an empty USB stick formatted to FAT32, single partition.
Rename the file to...

Hi sdamico :)

First obtain the Media Creation Tool (Download tool now) from here: https://www.microsoft.com/en-au/software-download/windows10 and follow the guide.
Extract the ISO file to an...

I'm on 0804 and no issues at all. Would be nice to know what improvements 1002 are supposed to bring.
