Hello all! I followed the Buildzoid video on tuning RAM for Ryzen X3D chips. I foolishly bought XMP 8000 ram because the X870 Tomahawk supported it. That led to some serious instability using the XMP profile. So I lurked for months trying to find a solution. On a whim I applied the Buildzoid settings to a memory try it profile embedded in the MSI Tomahawk. I was able to get down to 6000CL28 with the 8000MT kit.
I am wondering if there is anything that can be improved on these settings since the video is kind of old and meant for a 7800X3D, Are there any updates to the 9800X3D memory controller I should take into account? Anything I can push lower? These settings passed with flying colors in a full memtest86 run.
Thanks everyone.

Forgot to add the memory kit: [G.SKILL Trident Z5 RGB Series 32GB (2 x 16GB) 288-Pin PC RAM DDR5-8000 (PC5-64000)](https://www.newegg.com/g-skill-trident-z5-rgb-series-32gb-ddr5-8000-cas-latency-cl38-desktop-memory-black/p/N82E16820374449?Item=N82E16820374449)
What is the latency result?
Disable gear down mode and tighten tRFC. tRAS doesn’t do anything for performance (Buildzoid made a video about this), so you’re better off just maxing it out to 126 as it can make your OC unstable.
Rest looks good to me 👍
They were pretty meh on my system. Not bad, but not really any better than the expo tweaked timings asus provides with the crosshair hero
maybe you are not giving enough voltage for the 8000mhz? to get it working, you need vddp to be 1.05v and vddio 1.45v, also make sure that mclk/div mode is 2:1.
Disable PowerDownMode in BIOS
Disable HyperVisor if you want (SVM Mode in BIOS)
Disable Memory Integrity if you want (Windows Settings)
What did you try in terms of stabilizing 8000MT/s? I had a breeze getting it going on my Tomahawk with my older 6800 MT/s A-die kit.
