DFI AD73-RAID KT266A Motherboard Review

Subject: Motherboards
Manufacturer: DFI


This content was originally featured on and has been converted to PC Perspective's website. Some color changes and flaws may appear.

Even though this will be my first published review of a DFI motherboard, I have had lots of experience with this company’s products. We began working with DFI back in 2001 with the release of the KT266 motherboard. I had the board, was testing it, but with the release of the KT266A chipset, we all agreed that reviewing the older board was pointless and I waited for the new KT266A motherboard to arrive.

After I had that, had tested it and started on the review, DFI was promising me an updated version of the motherboard with more features making it friendlier to the PC enthusiast market. Being that cater to that market, I decided to wait for that board, the AD73, to arrive.

Now, we have that motherboard, tested it and are finally able to publish what I think is a complete review of DFI’s AMD line of motherboards: the cumulative end to a lot of work on DFI’s engineer’s part.

Many of you may not have even heard of DFI before as they are much more popular overseas and in the OEM market than they are with the DIY market. Since the move of Scott Thirwell from Abit to the DFI marketing staff, the company has been on a move to change that. I have gotten as many questions from DFI as I have asked them as they researched and tried to find out what the user wanted in their products. While not everything is in this particular model, I fully expect future DFI boards to implement most of what was suggested.

Here are the board specs:
