MSI Z890 "Memory Extension Mode enabled"

[BerArtVD]

Hi,

I was reading this article: https://www.msi.com/blog/msi-click-...overclocking-new-looks-and-unmatched-control/ and bumped on this line:
"According to a few tests with Memory Extension Mode enabled, we found up to 14% better performance compared to just setting XMP and calling it a day."

Memory Extension Mode in MSI Click BIOS X is only a click away and offers 4 preset modes at the same frequency —Performance Mode, Benchmark Mode, High Efficiency Mode, and Memtest Mode—to optimize memory parameters like speed and latency to improve performance in scenarios like benchmarking, gaming, etc.

But I do not understand the difference between the XMP profiles and the above setting? If I enable (before saving) the "Preformance Mode" and then click on save an exit (before actualy saving) I can see what the change are that will be made to the BIOS. This is a list of 10 rules. When I activate XMP1 it is only 2 rules of changes. So before I do anything I want to know what it means.

All those do is change a few memory sub-timings like tREFi. I checked yesterday. Its not a new magical fix exclusive to MSI. Same old stuff with a new marketing name.

Performance mode changes tRDRD_sg (from 21 to 8 and tREFi (7k to 32k) is all I found for the kit I tested. I presume it is different per set frequency. It knocked off 5ns in AIDA64

Thx! Clear, I tried the first setting "MSI Performance" and also do not see very much change ..

@ir_cow sins you know a lot how about the NPU, I am a (web)designer and use Adobe e.d. would it be beneficial for me to enable the Ai NPU boost?

I think Ai NPU boost is just changing the ratio up 1-2x with the word AI slapped onto it. Ring, D2D and NPU will boost performance (by lowering latency). However, make sure to run some stability tests to avoid crashes. Especially since you are using the computer for work. Not sure it will make any difference outside of gaming.
