Warning: This only works correctly for systems with less than 4 GiB RAM. New code should try GlobalMemoryStatusEx first.
Description
KiCHiK came up with this NSIS code to check free RAM using the System plugin (original forum posting)
The Function
System::Alloc 32 Pop $1 System::Call "Kernel32::GlobalMemoryStatus(i) v (r1)" System::Call "*$1(&i4 .r2, &i4 .r3, &i4 .r4, &i4 .r5, \ &i4 .r6, &i4.r7, &i4 .r8, &i4 .r9)" System::Free $1 DetailPrint "Structure size (useless): $2 Bytes" DetailPrint "Memory load: $3%" DetailPrint "Total physical memory: $4 Bytes" DetailPrint "Free physical memory: $5 Bytes" DetailPrint "Total page file: $6 Bytes" DetailPrint "Free page file: $7 Bytes" DetailPrint "Total virtual: $8 Bytes" DetailPrint "Free virtual: $9 Bytes"
