Low 90s in what app / game?
Update on my 5800X3D
Decided to try 1900IF / 3800Mhz RAM but with default C16.
Fired up the Matrix demo (CitySample_51_DLSS_Cinematic.zip) which is available here.

Watching system logs and look for event 19, inteconnect errors...
Certainly not stable at 1900 IF/FCLK. These X3D chips must be more sensitive to increased infinity fabric clock. I guess the IF (and RAM) matters less though with the increase in cache
I already know the RAM is good for 3800Mhz C14 with GDM enabled at 1.49V in BIOS, so set 3600Mhz/1800IF and flat 14 with GDM off.
So far so good
I also noticed there's a new 'Kombo Strike' feature in the BIOS under ADM overclocking with options for 1, 2 and 3. It doesnt says what it does but imagine its similar to PBO2 tuner, just with a fancy marketing name. Might try that after running a few more RAM tests
