Overclocking and System Setup

The Athlon MP processor is essentially the same as the Athlon XP processor. Therefore, it is likely and expected that the two would perform the same in terms of speed, heat and overclocking – and it is true. In fact, it was almost identical to my overclocking experience with Athlon XP 1800+.

Several readers have posted questions in the AMD Forums about how exactly I was able to change the multiplier on the processors. The reasoning is that the processors that AMD sends out to reviewers before they are made available to the public are already unlocked because most of them are engineering samples. While I cannot yet say why AMD has made it more difficult to cut the traces on the new packaging nor can I tell you a definitive way to unlock them, I can tell that the ones on the processors I received were in fact trace broken.

In the end, I was able to reach almost 1.7 GHz, coming in just shy at 153 MHz X 11x for a total clock frequency of 1683 MHz. This was of course at the maximum voltage available, 1.85v, and not on any dual-Athlon motherboards. I used the Epox 8KHA+ KT266A board to do the overclocking on the Athlon MP 1800+ as it was one of the few boards I had available that had support for the new Palomino cores and SSE support.

The system setup for the benchmarks is below. For the two-processor tests, I used the Tyan Tiger MP motherboard, the cheapest available, yet incredibly stable, dual-Athlon platform. For the single processor tests, I used the Athlon XP 1800+ processor on the Epox 8KHA+ KT266A motherboard. The memory that we used on the Tyan boards was 256 MB of Registered ECC PC2100, which will inherintently, slow the memory down some, thus affecting various tests slightly. But since Tyan officially requires the user to have Registered ECC memory I assumed it was only fair to include it in the tests against non-ECC PC2100 memory on the single processor test system.
