🔧 “MSI N1996” isn’t a real model number. It’s the PCB code (MS-7191 v1.0 / v2.1) printed on the board. The actual models are usually MSI RS482M or MSI MS-7191 (Socket 939 era).
Many N1996 boards have an older BIOS that will not recognize 2 GB DDR2 modules unless they are "low density" (16-chip, 8 chips per side). Modern "high density" 2 GB DDR2 sticks often cause boot failures. If upgrading, use 1 GB sticks for guaranteed stability. msi n1996 motherboard technische daten
