Я под персоналки не пишу, но английская страничка вики вот чего пишет. А вот как застолбить её - уже другой вопрос, я так полагаю - через PAE. https://msdn.microsoft.com/en-us/library/aa366527.aspx

AWE depends on Physical Address Extension support when reserving memory above 4 GB.[2] AWE was first introduced in Windows 2000 as a new API superseding the PSE36 method (from the Windows NT 4.0 Enterprise Edition) of accessing more than 4 GB of memory, which was no longer supported in Windows 2000.[3][4] Among the first applications to make use of AWE were Oracle 8.1.6[4] and Microsoft SQL Server 2000.[3]
If the /3GB boot flag is used to repartition the 32-bit virtual address space (from the 2 GB kernel and 2 GB userland) to 3 GB userland, then AWE is limited to accessing 16 GB of physical memory.[3] This limitation is because with only one GB reserved for the kernel, there isn't enough memory for the page table entries to map more than 16 GB of memory.[5] Additional restrictions on the maximum amount of memory addressable thorough AWE are imposed by the Windows licensing scheme. For example, Windows 2000 Advanced Server was limited to 8 GB, while Windows 2000 Data Center Server supported 64 GB.[6]
Единственно - это только из установленной планками физической RAM? Если так - то не факт, что это поможет ТС.
