X-bit Labs reports some facts about the overclocking capacity of the Athlon XP 2800+ :
We have already discussed the situation around availability of the newer Athlon XP processors earlier today (see this news-story), and I expressed some doubts about AMD’s ability to start the volume shipments of the 2800+ CPUs on time. By now I have received indirect confirmations to my concerns. Apparently, Athlon XP 2800+’s 2250Mhz frequency is very close to the highest core-clock the core can function at.
Unfortunately for AMD, I now have to admit that with Athlon XP 2800+, AMD has reached the point of the maximal frequency the Thoroughbred can achieve. Our friends from OverClockers.ru web-site managed to grab a sample of the mentioned processor and tried to overclock it. To their great disappointment, they only succeeded in launching the CPU at 172MHz FSB, while the nominal frequency is 166MHz. The resulting core-speed was 2327MHz. They did not test the processor on stability at this clock as there is no sense to overclock so fast CPU by 77MHz
