Alfred Eugene Mack appeals the district court’s order denying his motion for modification of sentence. Mack argues that the district court erred by failing to reduce his sentence based on Amendment 706 of the Guidelines, see U.S. Sentencing Guidelines Manual § 2D1.1(c) (2007 & Supp. 2008); USSG App. C Amend. 706, and United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005). As we recently observed, “Amendment 706 ... amended § 2D1.1 of the Sentencing Guidelines by reducing the offense levels associated with crack cocaine quantities by two levels.” United States v. Hood, 556 F.3d *429 226, 232 (4th Cir. 2009). Mack’s sentence was determined by the career offender guideline, USSG § 4B1.1, and was not based on a sentencing range lowered by the amendment. The fact that the district court reduced Mack’s sentence under 18 U.S.C. § 3553(e) (2006) and USSG § 5K1.1 is irrelevant to the applicability of Amendment 706. Hood, 556 F.3d at 234. Moreover, Mack’s contentions that the court could have considered a sentence below the amended guidelines range and that he is entitled to a full resentencing under Booker are foreclosed by our decision in United States v. Dunphy, 551 F.3d 247 (4th Cir. 2009), petition for cert. filed, 77 U.S.L.W. 3559 (U.S. Mar. 20, 2009) (No. 08-1185).

We have reviewed the record and find no reversible error. Accordingly, we affirm the district court. We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before the court and argument would not aid the decisional process.

AFFIRMED.
