When displaying the Radeon overlay (Shift Control O), both GPU VRAM UTIL and RAM UTIL are shown. GPU VRAM UTIL is obviously the 8G built into the card. But, if I have the HBCC Memory Segment feature turned off in Wattman (19.9.2), should I be seeing 4G (approx) listed for RAM UTIL? I noticed that if I increased the HBCC Memory Segment and enable it, the RAM UTIL value increases, so I'm assuming that RAM UTIL is the amount of system ram used. But if I have that feature disabled, why am I seeing anything there? It's almost as though the card is grabbing 4G of RAM at all times and that you can't tell it to keep its hands to itself.
