I have a 3900X + 2080 Super GPU with a ASRock X570 Board -- I've fully updated the BIOS, CPU chipset drivers, GPU driver, and Windows installation. My motherboard supports the feature and my understanding is that the Ryzen 3000 series CPUs are supported as well so the only thing left is on Nvidia's end if I'm understanding correctly. Currently they only have the feature enabled/functioning on their latest 3000 series GPUs, but is there really some hardware reason that it can't be done for the 2000 series GPUs or is Nvidia just being greedy and trying to force users to upgrade or some nonsense? Perhaps I'm misunderstanding something, but SAM simply allows the CPU to access/allocate more than the standard 256 MB of VRAM at a time no? Why would changing this require some "special modern hardware that only the 3000 series cards are capable of" -- at a glance, that seems hard to believe, but perhaps I'm wrong -- it could be my understanding is incorrect there. It just seems crappy that if you have a 2000 series or Super GPU then you can't use Resizable Bar/SAM even if the rest of your components all support it after updates. If there's not some hardware limitation on it being doable, I really think Nvidia should enable the feature at least one or two generations back. If they can do it and just won't, I find that pretty irritating. Or is their plan to enable the feature down the line? Thus far I've not heard anything about that yet, but here's hoping.
