MSI G41M-P21 LGA 775 Board

This motherboard fits LGA 775 Core 2 Quad and Core 2 Duo processors with a 1333, 1066 or 800 MHz front-side bus. The Intel G41 chipset provides dual-channel DDR3 support up to 8 GB and a single PCI Express x16 slot at version 1.0. It targets basic desktop builds and legacy hardware upgrades.

Sustained load behaviour

The board runs the VRD 11.1 power design for stable voltage delivery during long sessions. The Realtek 8103EL Fast Ethernet controller maintains 10/100 connectivity without extra add-in cards. Onboard Realtek ALC889 audio handles 8-channel output continuously. Four SATA 3.0 Gbps ports keep storage throughput steady.

Installation notes

Micro ATX dimensions fit most chassis designed for the form factor. The package supplies a CMOS battery, one SATA cable and an I/O back panel for immediate use. No WiFi antenna is included because the board lacks a built-in module. Verify processor stepping and memory speed match the supported list before fitting.

Questions about this item

How much power does the LGA 775 socket draw under full load all day?

The board uses Intel VRD 11.1 processor power design standard for the LGA 775 socket.

Which DDR3 modules must I already own to reach the 8GB maximum?

You need dual-channel DDR3 1333 (overclocking), 1066 or 800 MHz modules to fill the two slots up to 8GB.

Will my PCI Express x16 graphics card work in the 1.0 slot alongside older PCI cards?

The board has one PCI Express x16 slot at specification 1.0, one PCI Express x1 slot and one 32-bit PCI 2.3 slot for legacy cards.
