Effective memory clock is the actual frequency of the VRAM. Say, for example the AMD HD 7970, which has GDDR5 memory: its base memory clock is 1375 MHz, but its effective memory clock is 5500 MHz. There can be a difference between 4800Mhz and 5600Mhz, but it depends on the application. 2. OpenGL is a graphics API (application programming interface). This can be used on all operating systems.
