About this tag
Memory ranges in Windows refer to the address spaces assigned to hardware devices like graphics cards and PCI buses. Discussions on WindowsForum.com cover how Device Manager displays memory ranges for onboard graphics using shared system RAM, and how these ranges appear under 'Resources by type' for the PCI bus. Another topic involves SQL Server data corruption when a memory range is accessed via the SetFileIoOverlappedRange function, with a fix for Windows Vista and later. Users also troubleshoot issues where Windows 7 does not use allocated shared memory, as indicated by memory ranges in Device Manager, often pointing to driver problems on older hardware.
