LGA 775 Pentium 4 board

The DELL 915G motherboard uses the Intel 915G Express chipset and a Socket T LGA 775 interface for Pentium 4 processors. Four DDR2 slots accept 533 or 400 MHz modules up to 4 GB total. An ATX form factor provides one PCI Express x16 slot, one PCI Express x1 slot and two additional expansion slots for add-in cards.

Onboard video and dual Gigabit LAN

Integrated graphics output through a VGA port while two Intel Gigabit Ethernet controllers handle wired networking. Six USB ports and two SATA connectors support storage and peripherals alongside an Ultra ATA 133 channel and a floppy controller. The chipset runs at stock speeds with standard desktop cooling and no extra power phases.

Legacy I/O and expansion layout

A parallel-style floppy header, serial ATA headers and the Ultra ATA 133 connector cover older drive types. The single PCI Express x16 slot is wired for graphics cards, while the x1 slot and two general slots accept sound, network or I/O cards. No bundled software or accessories are mentioned in the specifications.

Questions about this item

How do I install the Pentium 4 CPU into the LGA 775 socket without bending pins?

Lift the socket lever, align the processor notches with the socket keys, lower the CPU straight down without forcing it, then close and latch the lever; the lever tension secures the chip — no screws or thermal paste are included.

What maintenance or replacement will the onboard video and DDR2 memory need later?

The integrated graphics cannot be upgraded; if it fails the board must be replaced. DDR2-400/PC2-3200 or DDR2-533/PC2-4200 modules can be swapped in the four slots up to 4 GB total.

What limit appears first when the board runs sustained loads with the Ultra ATA/133 controller?

The Ultra ATA/133 interface caps drive throughput at 133 MB/s, so storage bandwidth becomes the bottleneck before the PCI Express x16 slot or dual Intel Gigabit LAN saturate.
