The Asus M2N61-AX Motherboard is an OEM (Original Equipment Manufacturer) version custom built to be used inside of a Dell Inspiron 531 desktop computer. This motherboard and the CPU are the only differences between the Inspiron 530 and the 531, with the 531 providing the user with the more powerful AMD processor, which the 530 lacked.
This is an AM2 supported motherboard with an AMD Athlon 64 3800+ Sempron CPU, which uses an nForce 430 chipset. It runs an Nvidia Geforce 6150 Onboard VGA graphics processing unit that clocks at 475MHz and supports high definition play back.
There are available expansion slots for one PCI express 16X and one PCI express 1X, which are both compatible with PCI software, two regular PCI parallel bus', four DDR2 RAM slots, one VGA out port, an RJ45 and S/PDif in and out ports.
The M2N61-AX has a Realtek RTL 8201N 100M / Nvidia nForce Gigabyte Ethernet 10/100/1000 LAN connection (using the RJ45 as mentioned above), as well as eight USB ports (four situated on the back and four situated on the front). Connecting speakers to the motherboard will allow the use of Realtek's eight-channel high definition ALC888 audio codec.
