Finally, Microsoft has an irritating problem since long time in Windows 7 and Server 2008 R2 is recognised.
Many times Windows 7 contains incorrect RAM on computers that are a chipset with Integrated GPU have. Now Microsoft has released a hotfix to resolve this problem.
SYMPTOM:
Assumes that you have a computer running Windows 7 or Windows Server 2008 R2. The computer is running on a chipset that reserves memory for a integrated Graphics Processing Unit (GPU) that aperture range memory-mapped i/o (MMIO) does not support. For example, the computer has an Intel GMA 3600 GPU installed.
In this situation, Windows reports that less memory is installed on the computer, then actually is installed on the computer.
CAUSE:
This problem occurs because Windows locks the primary surface and then use the CpuTranslatedAddress address to shadow the primary surface. It is therefore the primary surface assigned exclusively from a segment of memory that is visible to the CPU.
Most integrated Gpus have a MMIO aperture range. In this situation, you must have Windows memory at startup are reserved, and expose the reserved memory as a dedicated memory segment. By default, must be a primary surface are located in a segment of memory that is visible to the CPU. This is a segment of linear memory space that exposed the GPU using a CpuTranslatedAddress address.
SOLUTION:
A supported hotfix is available from Microsoft. However, this hotfix is intended to correct only the problem that is described in this article. This hotfix only to systems that have the problem that is described in this article occurs.
After you install this hotfix, support Windows 7 and Windows Server 2008 R2 primary surfaces of Gpus that do not yet have a MMIO aperture range.
