I currently have an nVidia Tesla M40 12 GB that I use for various tasks, however I noticed that in nVidia-SMI only around 11.5 GB of VRAM is available. Task Manager in WDDM mode confirms that too even stating that some VRAM is "hardware reserved". I later noticed that right here on TechPowerUp there exists some alternate 12 GB BIOS versions. Apparently the 24 GB variant is in a similar situation, only apparently having roughly 22.5-23 GB of VRAM. However there's no full 24 GB BIOS on this site for the M40. So I'm wondering how these alternate BIOS versions work. How can there be 11.5 and 12 GB BIOS for the M40 12 GB? And is it possible to also modify the BIOS of the M40 24 GB to have the full 24 GB available?
