Intel发布了一份新的产品改变通知PDF，通知合作伙伴双核及四核Xeon的步进改变。双核和四核Intel Xeon 5100 Woodcrest以及5300 Clovertown将升级到G0步进。 G0步进降低了C1E挂起状态时的功率消耗，但Intel没有指明具体降低了多少功耗。另外G0也该进了VT（虚拟化）功能，包括： * APIC任务优先注册器 (TPR)虚拟化 * NMI-window退出 * 针对进出的高级VM退出信息所有G0步进处理器都将获得新的CPUID。Clovertown CPUID将从06F7改为06FB，而Woodcrest将从06F6改为06FB。同时新步进CPU还将获得新的SSPEC号码。本次步进升级同样需要主板升级BIOS以辨认新的微代码。更新微代码后，用户可以在多处理器系统中混合使用不同步进的处理器。
