The TLB issue only affected the original revision B2 Phenom X3 and X4 processors. These were the X3 8400 and 8600 and X4 9500 and 9600. The erratum was fixed starting with revision B3 (aka every other model other than 8400/8600/9500/9600).

Edit: The first B3's came out March of 2008 after which all B2's were EOL'd.
