Q. I purchased an EAH4650/DI/1GD2 V2 graphics card recently. This card should support HyperMemory function. That means part of the system memory can be allocated to this graphics card. However, according to the ATi control panel, no system memory is allocated to the graphics card. The memory size of this graphics card is still 1GB. This issue occurs under Windows XP only. HyperMemory functions properly under Windows Vista. How do I resolve this issue?

A. This is a software limitation. Windows XP will only support up to 1G of graphics card memory. Since the EAH4650/DI/1GD2 V2 card already has 1GB of onboard memory, Windows XP cannot allocate more system memory to the card. Consequently, it appears that the HyperMemory does not function.
