I reinstalled MSI AB and updated to the latest version of GPU-Z, both are now reporting VRAM usage correctly. This is very odd, I didn't even do a clean install of AB (kept settings), I wonder what could cause this sort of issue to require an application reinstall. As for boost clocks, I haven't noticed any real difference on my system. LE: And VRAM monitoring is broken again, it happened randomly while AB was running, it suddenly jumped from ~200 to ~4M again, without starting a game or touching AB at all. I guess reinstalling didn't get to the core issue. Maybe I need to try a clean sweep with DDU too, I'll have to see.
