So, I ran into something interesting yesterday when installing my new graphics card. A strange anomaly, I guess you could say:
I recently installed an ATI Radeon 4350 (Overclocked, but I haven't really noticed a difference. Nor is this important). The card has a 512mb of dedicated memory, and as much as I understand shouldn't use any more than that. I have have 4gb of ram installed, and Yes all 4gb are being used by the system.
Now here's where things get interesting. I checked the properties of my new hardware and it states that it has 512mb of dedicated memory, BUT also another 1gb of shared memory. Like I stated before, I have 4gb of ram installed and all reserved for the system. It is not sharing that memory.
Now here's what I think: The motherboard has NVidia integrated graphics with 1gb of dedicated memory (See where I'm going with this?). My hypothesis is somehow the new graphics card is accessing the unused memory of the old integrated graphics.
Honestly, I have no clue what's going on, but I found it an interesting thing to discuss. Any feedback would be nice, even if only to say, "You're an idiot."
