My 6570 card is causing 4GB of main memory to locked. That is half of the total 8GB not available. I found the formula used to calculate this
but no clue as what is used for. Can it be turned off or controlled in some way? Is this a feature on all Radeon cards? I have always used
ATI/AMD video but this is unacceptable. This has nothing to do with the OS or MB.
