  • Two Gigabit LAN ports provide redundant network connectivity
  • 1 PCIe x16 plus 1 PCIe x4 and 2 PCI slots enable flexible expansion
  • 4 SATA 2.0 ports plus 1 IDE and 1 FDD support diverse storage configurations
  • Micro-ATX form factor fits compact chassis while retaining full feature set

Socket LGA775 Micro-ATX Platform

The DFI EL330-DR is a Micro-ATX motherboard built around the Intel Q45/ICH10DO chipset for Socket LGA775 processors. It accepts Intel Core 2 Quad, Core 2 Duo, Pentium and Celeron CPUs. Four DDR3 DIMM slots support up to 8GB of system memory at 1066MHz. The board targets embedded or legacy desktop builds that require long-term availability.

Expansion Layout and Rear I/O

One PCIe x16 slot and one PCIe x4 slot handle graphics or add-in cards while two legacy PCI slots remain for older peripherals. Storage connectivity includes four SATA 2.0 ports, one IDE connector and one floppy header. Rear I/O provides two Gigabit LAN ports, eight USB 2.0 ports, one VGA output and two COM ports. An 8-bit digital I/O header supports industrial control tasks.

DDR3 Memory and SATA 2.0 Limits

DDR3 memory tops out at 8GB across four slots and 1066MHz speed, restricting capacity for modern multi-tasking workloads. The SATA 2.0 interface caps drive throughput at 3 Gb/s, so newer SSDs will not reach their rated performance. PCIe expansion uses older signalling rates, limiting bandwidth for current high-speed add-in cards.

Questions about this item

What bandwidth does the PCIe x16 slot actually deliver?

The board provides one PCIe x16 slot and one PCIe x4 slot for expansion cards.

What are the exact mounting dimensions for this Micro-ATX board?

It uses the standard Micro-ATX form factor with mounting holes that align to Micro-ATX chassis standoffs.

How do I install memory correctly on the four DDR3 slots?

Populate the four DDR3 DIMM slots with up to 8 GB total at 1066 MHz; the common mistake is exceeding the 8 GB limit or mixing speeds.
