The processor operates at 1.66 GHz, and supports single-channel DDR2 667 MHz memory. Due to the lowered thermal footprint of the chipset, ASUS used a single heatsink to cool both the processor and chipset. It provides two DDR2 DIMM slots to hold up to 4 GB of memory. The lone expansion slot is a PCI. Storage comes in the form of two SATA 3 Gb/s ports. Connectivity includes 6-channel audio, 10/100 Ethernet, four USB 2.0 ports on the rear panel, four by headers, D-Sub for display, serial and parallel ports, and PS/2.
