Using Everest to display my video GPU and video Memory clocks (on the OSD), I see that in 2D/desktop mode they are 500mhz/594mhz (GPU/Memory). This is normal and expected for my cards (x1900 Crossfire edition and x1900xt).
When I go into 3D/gaming mode, I'm alt-tabbing back to my desktop so I can see the Everest OSD, and I see that my clocks have increased to 621mhz/721mhz respectively. Again, this is normal and expected.
What I don't understand though, is why is my memory clock rate only being increased to 721mhz when my cards are rated at 1450mhz EACH? The GPU is rated at 650mhz, so I figure 621mhz is pretty much close enough. But the memory clock is running at half the rate, let alone the fact that I have 2 cards, so shouldn't I be getting 3ghz of memory speed?
I'm probably thinking about it the wrong way, so any clarification is appreciated.
