Good setup for QFN on 48GB Ampere GPU (A40)

Anyone have a good config they've found for QFN on a A40 (or similar Ampere GPU(s) with 48GB VRAM)? The system the card is in has 128GB of RAM (DDR3); right now it's running 27B but I'm curious if there's a way to move to QFN to maybe get better speed/a little more smarts. TY in advance!
