Problem Solved: Asus Rog Strix X870E-E vs AMD Processor vs DDR5 Overclocking Compatibility

Before about two months after having my new PC, I had a strange behavior when I wanted to reboot the system "say for any driver update or windows update ...etc". In that time my motherboard Asus Rog Strix X870E-E Q-Code LED indicated once rebooting from Windows the code "0d" and the system stuck without even reaching the BIOS screen. So I had to force shutdown the system after which everything was fine. Code 0d was in terrible so frequent repeating after each rebooting process especially after I enabled EXPO profile from BIOS. 
 
Things I did since more than one month to investigate the situation:
1. Clean installed Windows 11 and BIOS updated from 0706 to 0804. BIOS was kept as default settings. 
2. Did not install Armoury Crate.
3. No third party software installed.
4. RAM sticks removed and reinstalled back in slots A2 and B2.

5. RAM sticks removed and installed back in slots A1 and B1.
6. Other new RAMs installed.

 
After having all above mentioned procedures, code 0d continued coming after rebooting from Windows.
 
The only solution (but very unusual and not practical) that kept the system stable but under default BIOS settings is the following:
** I installed 32X4 gb RAM sticks from the same DDR5 brand (2 Kits). After that, with 128 GB RAM, the system got a stable rebooting. However, code 0d came but in so less frequent and I was happy that I did that and shared it with others.
 
 The following is the final permanent stable and robust solution:
** After all these trials, I came to know from people that AMD (  AMD Ryzen™ Processor Overclocked Memory Compatibility List ) recommended specific Memory Compatibility List with specific "Overclocked Timings" for certain DDR5 brands. From here I started another investigation. 
I found Corsair DDR5  not existed for AM5 and this was a major concern to me as I am using  X870E-E  motherboard with AM5. I also found the same recommendation for DDR5 compatibility vs motherboard in ASUS website  (  ROG STRIX X870E-E GAMING WIFI | Gaming motherboards|ROG - Republic of Gamers|ROG Global  ). 
Immediately, I went for Teamgroup 32X2 gb with Overclocked Timing 6000/38-38-38-78. Once I installed this new DDR5 kit in A2 and B2 slots, everything back stable normal. I kept the system under default BIOS 0804 and rebooted the system for more than 3 days continuously. It was just a stable system.  
Now, it is the time to enable EXPO profile for 6000 MHz. After doing that, the system showed a stable rebooting all the time without a single code 0d since more than three days. 
I installed third party softwares like : GPU Teak III , L-Connect 3 , AIDA46 Extreme ...etc. Still the system stable.
 
Problem solved. So it is just to go to  AMD (  AMD Ryzen™ Processor Overclocked Memory Compatibility List ) recommended specific Memory Compatibility List with specific "Overclocked Timings" for certain DDR5 brands  and see the compatible kit for your AMD processor.
