Test Setup and Overclocking
This content was originally featured on Amdmb.com and has been converted to PC Perspective’s website. Some color changes and flaws may appear.Let’s jump right into things here. I am sure you all are aware what the Athlon Thunderbird and Duron processors offer the user, so I won’t bother describing (again and again) about the core and technology of the Thunderbird. Besides, the Athlon MP has changed much of that.
The test setup, that you see below, is pretty standard. I decided to use a couple different motherboards, one AMD 760 and one KT133A. Using the new king of the AMD 760 hill, the Epox 8K7A and one of the better KT133A motheboards, the Asus A7V133 I have lined up what I think will give a clear indication of the speed increase from 1.33 to 1.4 GHz as well as how the Duron 950 MHz fares.

As you might guess, the Duron 950 MHz overclocked much more (on a percentage basis) than the 1.4 GHz Thunderbird. Using the KT133A for overclocking, the Duron was able to reach 1.3 GHz very comfortably without any freezing or errors. Pushing the Athlon was a bit more of a hassle. By raising the FSB and lowering the multiplier, I was able to find its limit, with standard air cooling, to be 1.65 GHz. This is certainly a great bit of overclocking. While I haven’t looked much into, the folks at AthlonOC seem to think the steppings and codes are behind it all. I suggest you give them a look and see what they say about it.
