Also, we tried underclocking the CPUs as well while still running an overclocked FSB, but this made no difference in the stability of the 2500+s or the 3000+.
Now the next question that you might be thinking is what do I really loose if I am "stuck" at 166MHz FSB. We thought we would look at this as a worst-case scenario as we have not seen any chips that would not do at least 185MHz FSB stable."[/COLOR]
Update by Per: You might be interested in taking a look at [URL=http://lowyat.isentral.com/guides/athlonxp/]this site[/URL] and their findings regarding the product code all AMD CPU's has... Disappointingly though [H] did not include the product codes of the CPU's they tested.
