Asus Rog Strix X870E-E EXPO Profile issue versus bios update
I had bios 0706 and found the EXPO profile does not give my 64 GB RAM full speed at 6400 MHz. Unfortunately RAM speed running at 3600 MHz only.

This morning, I updated the bios for the Motherboard to 0804 and found still EXPO profile issue not resolved. As the case in 0706, I need to stay with Bios default settings. So neither 0706 nor 0804 help to resolve the EXPO profile compatibility.

Then, I tried to go back to bios 0606 but could not. The Bios screen says: Bios version not Valid ...!!

I found the same case with people owning the same MB at ASUS forum.

Please Asus, do something for ASUS ROG STRIX 870E-E. It is supposed to be a high-end motherboard. Let us feel that.

It's not my thought, I copied data from AMD website. It says, with 4 sticks RAM the processor supports the speed of 3600. No matter what kind of sticks you buy. You can overclock it a bit, but you will never get the speed you aim for.

Simple explanation. It is the CPU that is reading from RAM and writing to RAM. There are 2 buses between them, address and data. CPU sets the address it want's to read, the clock is ticking, after so many ticks the RAM sets the data on the data bus. The number of ticks is fixed. The RAM cannot do anything faster than CPU supports. When CPU needs to read some data, and it expects that data after 30 ticks of the clock, the data must be there exactly on that moment. It cannot be faster just because RAM can do.

In summary, your system works fine now.

With no doubt, Asus Rog Strix X870E-E , really needs more support from Asus.


they do not need anything.....you need to understand what you are doing before doing it......4 sticks will never support this speed.....

having 4x32 GB sticks was needed solution as I mentioned to resolve the headache called Q-Code "0d".

Update:
Just now, I removed the two sticks from A1 and B1. So total RAM = 32x2 GB.

When I switched on the system it took expectedly 5 minutes to train the memory. Speed changed from DDR5-3600 to DDR5-4800 without the EXPO profile.

When I restarted the system from Windows; guess what :) ….. the original problem I indicated in the link above came back and Q-code “0d” appeared.

I surrender now. I will back to 4x32 GB solution till Asus will have a solution.
