B650E-E XMP unstable memory (AGESA 1.0.8.0 BIOS v1813)

BIOS v1813 did not allow activating XMP. My DDR5:

the configuration in the images below on 6000MTs was not stable either:

I left the configuration in the images below in a more standard mode, but activating NITRO and MBIST, so I left the timings up to the system. I preferred not to test stability in applications like TM5 because I know it will crash.

Hi there,

This memory kit is not on the QVL. 6400MT with 64GB can to be tough on AM5, hence there are no qualified kits at this density and speed on the QVL. If unable to pass tests such as Karhu RAM Test it's possible that you will encounter stability at some stage, however, if data integrity is not vital simply use the system till such a time you encounter issues

I also reported it to the memory manufacturer.

You are absolutely correct. But if a B650E is going to handle it - it’s going to be the E-E. That VRM is beefy.

The issue is that the user purchases equipment where the memory should be supported, regardless of the manufacturer, therefore, the motherboard being limited by the pre-tested set must be sold together with the compatible type of memory. A standard answer does not solve the problem, especially when the market is free and the motherboard manufacturer has chosen to allow this freedom of choice between different memory manufacturers. That's why I also reported the type of marking on the integrated circuit to expand the possibility of testing without being subject to political issues between countries (this is irrelevant in the eyes of the user) and even so, Asustek has an obligation to mediate the solution to the problem.

 

Hello, not sure if this was put through a translator but some of your post doesn't make sense.

ASUS provides a QVL so that the user has the best chance of obtaining stability when overclocking. 
Contrary to marketing claims, this doesn't provide a guaranteed, foolproof method for automatic overclocking. This makes sense given that  the CPU's IMC is a crucial factor in determining the success of memory overclocking.
