Soyo's K7ADA ALi DDR Socket A Mobo...
With some Crucial PC2100 RAM and a WBK38 thrown in!

It seems that regardless of which PC component we speak of today the subject of bandwidth, and more specifically memory bandwidth, seems to take center stage. Recent discussions in the video card arena have really brought the importance of alleviating the memory bandwidth bottleneck to the top of many enthusiasts' minds. Video cards are not the only parts where performance gains can be realized by increasing available bandwidth though.

In the never-ending quest to bolster the overall performance of systems based on their CPUs both major players, AMD and Intel, have embraced newer...potentially "faster"...memory technologies. Intel's current flagship setup, a Pentium 4 coupled with expensive RDRAM, shows huge memory performance gains. AMD has gone a different route though, and are promoting chipsets that utilize much less expensive DDR SDRAM. AMD's own DDR enabled 760 chipset was the first to hit the streets, and even at this relatively "immature" stage is showing an approximate 10-20% increase in available bandwidth. With a little "maturity", and the influx of true CAS2 PC2100 RAM there is potential for even greater gains. Unfortunately, the AMD 760 chipset isn't widely available (and probably won't ever be), opening the door for third parties like VIA Technologies and Acer Laboratories (ALi) to become the dominant manufacturer of DDR chipsets. VIA already has DDR enabled chipsets available for the Pentium III and Athlon and will soon have one available for the Pentium 4. Their Athlon part (the KT266) has hit a few speed bumps along the road of acceptance though, which has allowed ALi's ALiMAGiK 1 to garner a lion's share of press.

The board we've got in the HotHardware Labs today, the Soyo SY-K7ADA, is based on the ALiMAGiK 1. Soyo is no stranger to the "Performance" motherboard market, having offered excellent products based on virtually every major chipset to be introduced in the last few years. Their SY-6BA+100 was among the best BX based motherboards, and was universally praised in virtually every review. Is the SY-K7ADA Soyo's next winner? Let's find out...

The specifications and feature list seems very complete...and so is the bundle, with one notable exception we'll get to a little later...


Included in the box with the SY-K7ADA, you'll find a basic users manual, a CD containing all the necessary drivers for the chipset and on-board sound, the usual package of cables and surprisingly, a small bag of thermal paste!  It was great to see this simple addition; with motherboards based on the same chipsets usually being so similar, small items like this may sway your decision from one product to another.
