How To Tell An “Old” From A “New” 2200+ TBred

At least one reseller has banner ads talking about “new Thoroughbreds” with “smaller core, cooler operation and increased headroom” at various websites including . . . uh . . . here.

BTW, our wide banner ads come to us from our ad agency Ad-Flow. The companies that advertise through them don’t deal with us, and we don’t control (or even know) what’s going to be displayed.

Is this a Revision B TBred or isn’t it? How can you tell?

There’s a few ways to tell the difference between the two:

An old TBred 2200 will begin with the code AXDA2200DKV3C. The “K” means it’s supposed to run at 1.65V.

However, according to AMD’s datasheets the “new” 2200+ is supposed to run stock at only 1.6V. Therefore, the code for that should be AXDA2200DUV3C

Another indicator is that the second line of code on an old 2200+ will begin with something like “AIRGA,” while a new, revision B TBred will have something like “AIUAB.”

For the website in question, the sales page for the processor gives no indication that what they are selling is a Revison B CPU, and the AXDA code on the page indicates an “old” TBred.

So don’t make any assumptions about this, because in this instance, if you ordered and got an “old” one, that’s what they said they were selling you, and if you don’t want it, they’ll take out a restocking fee.
