Overclocking and System Setup

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

The DFI AD73 is the first DFI motherboard I have seen to make a good attempt at giving the user some overclocking options. They have included nearly all the options an overclocker needs such as FSB adjustment, multiplier changes and Vcore options. While the bus speed and Vcore changes can be done in the bios, to change the multiplier, you will still have to use a dipswitch setup method. While this isn’t a big problem, it just means that if you have taken the time to unlock your processor that you will need to take a little more time to adjust the settings on the board.

My short overclocking tests on the DFI AD73 RAID board showed it to be competent, but not overly so. I was able to reach a front side bus of about 158 MHz with an unlocked processor without running into any problems. After that I noticed some video tears and minor instability. Overall, not a bad performance for DFI’s first jump into the overclocking realm.

The system setup may look a little odd to some of you. :) Today’s article is the first to include the Intel Pentium 4 processor benchmarks. Some of you will complain, and others will praise – but that is to be expected. However, I do want to note that the P4 I chose to use is not an exact comparative processor here. The Intel P4 1.6A (based on the Northwood core) is a less expensive processor than the Athlon XP 2000+ and so isn’t in the same field, in reality. However, this is all the P4 hardware I have here at the time, though I am working on getting a setup that will allow closer comparisons between AMD’s and Intel’s systems. The motherboard I used was the Shuttle P4X266A motherboard. A big thanks to Shuttle for helping me out with that! Also, thanks goes out to Monarch Computer for supplying me with the P4 1.6A processor.

Other than that, the tests and benchmarks are the same. Off we go!
