You may in fact have point. However, I bet the parity, ECC, or whatever had more to do with it than clcok speed. Some of the older boards couldn't accept non-parity (or parity can't remember which). But, in most cases, clock speed can be safely lowered below guaranteed operating spec, but not above.
Of course, the O/C'ing community has shown in many cases that stuff is spec'd at a much lower speed than it is capable of doing. There are many reasons for this... but regardless, if AMD sees you O/C'd your chip by 1MHz over spec'd range, and poof, warranty is null and void.
Anywho... if I'm wrong and misled someone, sorry....

The rating just means the MAX speed the ram was tested at the factory and GUARANTEED to operate at. Just like the Athlon XP. You can buy a 3000+ and run it at 500MHz. not sure why you'd want to, but you could.
I'm no expert on RAM by any means, but I think this is partially false or at the very least misleading. I purchased some PC133 RAM and put it in someone's computer who had previously been using 66MHz ram. The computer would not even boot with the new RAM in it. Now I remember way back when there was issues with parity vs. non-parity and stuff like that so I don't know what the culprit was, I just know that newer RAM wouldn't work in the old computer even though the type was the same (I think they were both SIMMs)
