Good day, miniZ!

I am running v2 miniZ for some time now, runs like a top without any issues on Win10 running variety of green cards on 2 different rigs. Recently got a 2080TI and needed to D/L miniZ v2 for a new rig and no can do because it's gone? So, I D/L v1.6w and got up and running but cannot run this card below 81% power? It crashes and Windoze takes over to announce that "stop code :Video TDR failure What failed: nvlddmkm.sys" shuts me down and restarts my computer. After much experimentation with various settings, I am currently running straight and true at 81% power (~920mv) 0 core/-500 memory, 242 watts with 42.3 hashes. Not bad, but I want to get the power lower. I will give up a hash or two to get this thing down ~200. Any idea what's up? Sure wish I could run it on v2 I think, but making big changes to other rigs for 40 watts is more than I care to do. Anywhere to score a D/L of v2 to try? Thanks for any help and your fine product.
