Building a computer Part 2 – That mother of a board
March 9th, 2010
By Gordon Meyer
Back when personal computers were new, motherboards were relatively simple devices that simply served as kind of a parking garage for all the circuit boards needed to complete a computer’s functionality. Key functions like graphics, sound and even connecting to printers and other computers required its own dedicated “card” that slipped into slots on the motherboard.
It’s a very different story today. The MSI 890-GXM motherboard that, together with the AMD Phenom II X4 CPU forms the foundation of my new system, is actually a pretty sophisticated piece of electronics. Although this specific motherboard is made by MSI, the same basic design, features and 890GX chipset can also be found on motherboards made by ASUS and Gigabyte. (As an aside, AMD is planning to launch a six-core version of their Phenom II processor later this year called the Phenom II X6, which will be supported by the 890-GX.)
This board was designed for graphic-intensive applications like games and HDTV, which means it has to have three big qualities: Kryptonian speed, surround sound that would rival your nearest Cineplex and incredibly sophisticated HD video capabilities. Part of the speed comes from the 890-GX’s support for DDR3 memory, which transfers data at up to twice the speed of its predecessor DDR2 memory technology.
To describe the motherboard’s graphics capabilities, I turn to IT News Online: “With Integrated ATI Radeon HD 4290 Graphics, users can enjoy accelerated and enhanced high definition and 1080p Blu-ray playback including dual-stream PiP (Picture in Picture) on Blu-ray 1.1. Standard DVD movies can be viewed in near high-definition quality with DVD upscaling with post-processing to enhance standard and low resolution videos and movies on HD displays. ATI Radeon HD 4290 Graphics are designed to decode and play back Blu-ray and other HD content with support for MPEG2, VC-1 and H.264 formats.”
One of the things I find really cool about the 890-GX’s graphics is the built-in DVI and HDMI ports in addition to the standard VGA connector. This makes it easier for a system built around this motherboard/CPU combo to serve as an incredibly sophisticated home theatre system complete with Blu-ray player/burner (sold separately). For those people who want uber fast gaming graphics, this motherboard supports up to two high-performance ATI Radeon Premium Graphics cards with ATI CrossFireX technology. Coincidentally, AMD acquired ATI a few years ago to take advantage of the latter company’s expertise in high-end graphics.
Moving on to sound, since the 890-GX was designed for use with Blu-ray drives and uses the Realtek ALC889 audio chip that fully supports Blu-ray’s 24-bit / 192 kHz lossless audio standard. The board includes a fiber optic digital audio out compatible with most Dolby Digital/DTS multichannel surround sound amps and receivers as well as 7.1 channel audio connectors.
In terms of connectivity, you have a now-standard Ethernet/LAN port that can support speeds of up to a full gigabit (1,000 megabits) per second, both USB 2.0 and the new USB 3.0 ports for extra high speed connections to external devices, plus full support for the latest generation of SATA III connectors for hard drives with up to 6Gbps bandwidth. This will come in very handy with the 2TB Seagate Barracuda XT hard drive I’ll be installing on this system. (More on the Barracuda XT later in this series)
Here’s the bottom line on connectivity. The more sophisticated and bandwidth-intensive graphics you have, including HD video and 3D HD, the bigger and faster a data pipe you’ll need to handle all that info. So you want SATA III and USB 3.0.
As I wrap up this installment in the series, it’s important to remember that pretty much all motherboards these days are designed to work with specific families of CPUs. The 890-GX motherboard can only be used with the Phenom II family of CPUs from AMD and both complements and extends many of the capabilities of those CPUs. If in building your own computer, you decide to use something other than an AMD Phenom II processor, you’ll want to be sure you’re using a motherboard with the newest chipset designed for your CPU.
Coming up later this week, choosing the right case.
