Ooh, that seems to have solved it. Haven't had a crash yet, ran The Outer Worlds for hours (addicting game!), ran FFXIV, ran GW2, no lockups. And, if there is much of a difference at idle in watt usage, I don't see it on the UPS meter. Thanks a million! (also of note, when using the valve ACO, as others have noted, you don't even have to do the above to (apparently) solve the problem. unfortunately, that has other issues, my V64 wont clock up high enough when using ACO for some reason, so i dont use it).
