AMD's 3D V-Cache technology has been the holy grail for gaming ever since the inception of the Ryzen 7 5800X3D. With Milan-X and Genoa-X, the idea of vertically stacking cache chiplets atop CCDs spread to servers as well. Interestingly, it turns out that Asus' WRX90 "sTR5" motherboards for the Threadripper 7000 lineup feature an option to manually override or disable 3D V-Cache in said chips per Videocardz. However, no known Threadripper CPU hosts 3D V-Cache, at least not yet.
The documentation for the Asus PRO WS WRX90e-SAGE SE motherboard has a setting titled "3D V-Cache". The description and configuration options, per our deduction, indicate that this feature is used to disable V-Cache chiplets, either completely or based on the number of stacks. Important to note that motherboards for AMD's Genoa-X lineup had a similar setting that allowed users to disable the extra cache.
