2.0A Ghz Processor, What Does The "A" Mean?

[Counter-Strike]

I want to buy a 2.0A Ghz processor for my 2nd P.O.S. Dell. Now, it says it supports up to 2.4 Ghz, 400mhz FSB, and 512k cache. But, would it not work if it has that "A" in it? What exactly does that mean?

I don't want to buy it, then have it put in and not work. Here are the specs for the Dell I have:

Scroll down to processor.

Thanks!

It will work. Don't worry. Btw, how much are you spending on that proc?

Like $35, my dads friend owns a computer store, so I am getting one cheap off of him.
