For what it's worth,
SharkyExtreme (a strong AMD backer) also tested the XP2200+ and came to the same general conclusion as THG:

On the surface, the 0.13-micron Thoroughbred would seem to have a lot of overclocking potential, but the actual results were a bit disappointing. If you're thinking of buying the Athlon XP 2200+ for overclocking purposes, then stop right where you are. The highest reliable core speed we could get was 1931 MHz using a 143 MHz FSB and a core voltage of 1.775V. You may be looking at the core voltage and wondering why we didn't use 1.8V or higher, and that would illustrate the main problem we had when overclocking.
All overclocking exercises are a give and take between core speed, voltage and overall heat levels and stability. The Athlon XP Thoroughbred took this to a whole new plane, as even slight voltage increases would ramp up core heat quite noticeably (like you had crossed a line in the sand), while lowering the overall overclock speed. Finding a happy medium is a tedious and extremely long-term process, and even hitting over 1.9 GHz took a whole lot of tweaking. For all testing we used a Vantec copper HSF, a 7000 RPM fan and Arctic Silver 3, and it was still tough going at some points.

Mind you, they liked the CPU and gave it an 8.5/10 rating.
