Because the processor uses Quad Data Rate bus the effective bus speed is 533 MHz This processor is labeled as Pentium 4 2.8A GHz. This is done to distinguish this part from Pentium 4 2.8 GHz processors with different set of features. ◆◆◆以上资料摘自产品官方主页CPU-WORLD等，以拿到产品实物为主                   如果您无法使用支付宝，可向以下银行直接汇款
