While a number of features are different between the EP45-DS3L and EP45T-DS3R, the layout isn't remarkably different. Starting with the system memory again are four DIMM slots in the upper right hand corner next to the 24-pin ATX and FDD connectors, but this time around, the memory interface is for DDR2. The P45 motherboard supports up to 16GB of DDR2 memory with supported speeds of DDR2-1200/1066/800/667MHz.
Surrounding the Intel ICH10 Southbridge are six Serial ATA 2.0 ports, one IDE connector, two USB 2.0 headers, front panel header, and the CMOS battery. The ICH10 is using the same heatsink as what's found on the ICH10R with the GA-EP45T-DS3R. While the GA-EP45T-DS3R has its IDE connector located along the edge of the PCB and rotated 90 degrees, the GA-EP45-DS3L does not but is just situated near the SATA ports.
The expansion slots on this motherboard include four PCI Express x1, two PCI, and one PCI Express x16. The lone PCI Express x16 slot is PCI-E 2.0 compliant.
The heatsink covering the Intel P45 Chipset is the same as what's found with the EP45T-DS3R. With both motherboards relying upon the same Chipset, both of these motherboards support the same Intel LGA-775 processors. In the upper left hand corner of the CPU socket is the 4-pin ATX power connector.
At the I/O panel are two PS/2 ports, optical S/PDIF output, coaxial S/PDIF output, eight USB 2.0, one Gigabit Ethernet and six audio jacks. Some of the other ASICs on the GA-EP45-DS3L include a Realtek ALC888 HD audio codec, a Realtek 8111C Gigabit Ethernet adapter, JMicron 368 IDE, and ITE IT8718 Super I/O.
