Virtual Memory Constraints in 32-bit Windows: an Update
نویسنده
چکیده
This paper discusses the signs that indicate a machine is suffering from a virtual memory constraint in 32-bit Windows. Machines configured with 2 GB or more of RAM installed are particularly vulnerable to this condition. It also discusses options to keep this from happening, including (1) changing the way 32-bit virtual address spaces are partitioned into private and shared ranges, (2) settings that govern the size of system memory pools, (3) hardware that supports 37-bit addressing, and (4) hardware that supports 64-bit addressing but can still run 32-bit applications in compatibility mode. Ultimately, the option of running Windows on 64-bit processors is the safest and surest way to relieve the virtual memory constraints associated with 32-bit Windows.

Virtual Memory Constraints in 32-bit Windows
Many server workloads can exhaust the 32-bit virtual address space in the Windows server operating systems. Machines configured with 2 GB or more of RAM installed are particularly vulnerable to this condition. This paper discusses the signs that indicate a machine is suffering from a virtual memory constraint. It also discusses options to keep this from happening, including (1) changing the way...
متن کاملWindows Operating System Agnostic Memory Analysis
Memory analysis is an integral part of any computer forensic investigation, providing access to volatile data not found on a drive image. While memory analysis has recently made significant progress, it is still hampered by hard-coded tools that cannot generalize beyond the specific operating system and version they were developed for. This paper proposes using the debug structures embedded in ...
متن کاملNetwork Connections Information Extraction of 64-Bit Windows 7 Memory Images
Memory analysis technique is a key element of computer live forensics, and how to get status information of network connections is one of the difficulties of memory analysis and plays an important roles in identifying attack sources. It is more difficult to find the drivers and get network connections information from a 64-bit win7 memory image file than its from a 32-bit operating system memor...
