I have seen this many times before, not only with my very own CPU but in other circumstances ad well. Remember all the press a few years back about how a certain marking of P2-300s would overclock to 450MHz and even 500--when 450MHz was the fastest P2 at the time? That was a remarking. Actually why delve into the past? Take almost any newly manufactured low-end or mid-range chip today, even intel chips. Yields have been very good, especially for AMD. Quite a few of these chips are remarked well below what their test value was. I have heard (but haven't verified at all or seen for myself) that some of the latest Athlons of series AXIA and AZIA are labelled at around 1500MHz. > > 1200's, AMD will sell 1200's as 900s.

Do you think that AMD and Intel have a different set of manufacturing equipment for each and every CPU revision? How inneficient would that be, balancing the production capacity of each one with the market demand. This is actually fairly public knowledge. Please feel free to contact either manufacturer on the issue... Don't trust me, trust the source. _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
