What is an Athlon K7 700mhz with a 900mhz core?

Is this junk?
I saw it for sale at Icompz.com for $235.00

Is something like this made by AMD and do they still warranty it?

Thanks,rnmcd

No, it's not junk. It's most likely a week 17-19 Athlon.
Those Athlons were shipped as 700-750 mhz but had 900 mhz cores. In other words, they are 900 mhz certified cores in sheep's clothing. Most Athlon overclockers want to get their hands on them because 900 or higher is garaunteed with those particular Athlons. It's legit, but a bit pricey. Then again, lots of people wanting to snatch those up.

There's really no such thing as a "900mhz core"

In reality, these are parts that, if they had passed all the tests, would have been marked 900. But instead, because they failed some tests, they were down binned (and retested) at a lower speed until they passed.

A "900 mhz" core does NOT mean that 900mhz is guaranteed, as jj650 suggested
