英文原文出自 http://fab51.com/cpu/barton/athlon-e23.html 转载请注明出处英语水平极其有限,敬请指正. 此文章适用于Barton,Thoroughbred,Thorton和Applebred核心的CPU,相应产品为Athlon XP,Sempron和Duron.当然,这些内容未必一定正确的,请自己斟酌.
桌面型CPU各金桥功能
L1: 连接L3和BP_FID
L2 L9: 2级缓存控制
L3: 默认倍频设定
L5: CPU工作模式设定
L6: SFID,移动版CPU倍频设定
L8: SVID,移动版CPU最大核心电压设定
L11: VID,默认启动电压
L12: CPU FSB设定
L1:连接L3和BP_FID L1金桥连接L3和BP_FID管脚,因此为了实现在主板上改变倍频,L1必须是全部连接的. 
L2:2级缓存控制 通过L2控制2级缓存的大小,因此默认情况下L2是全部连接的. L9是全部断开的,这并不影响到L2的设置.(但是,当从CPU外部控制2级缓存时,它又是必需的) 
注意,这和你看CPU的方向是相反的

尽管这些金桥都是连接的，正确地做法是修改L2缓存并不是必要的操作 我们建议你使用Prime95（软件使用方法不在本文讨论范围内，使用方法见这里）做个极端测试。 我认为L3[1]和L3[0]可能是对L2缓存无效区域的选择。这个金桥似乎和Palomino的功能一样。请查阅这个页面。Palomino/L2 details L3：系统倍频设定
警告：在被超级锁定的Athlon XP和Sempron中，即使你改变了金桥的连接依然不会改变倍频。对于设定Athlon XP的倍频来说，这些金桥是非常重要的。 
L3-FID 4连接：5X-12.5X L3-FID 4断开：超过13X 在这个页面上，倍频金桥就是L3-FID金桥。

L5:CPU工作模式
XP,MP,Mobile….它们都是由生产的时候所具有的金桥决定的。因此，把它称为“生产ID”可能更合适。 
L5[3]连接：多处理器支持 L5[2]连接：移动处理器模式 L5[1]断开：默认（L6有效） L5[0]连接：默认（L8有效）

OPN:指令编号
令人惊奇的……即使在CPU运行期间改变了金桥的状态CPU依然会继续运行。这个改变在Mobile版和桌面版相互转变的时候都是可能的。这个情况在T-Bred1700+和K7S5A组合的情况下验证过。不管怎么样，据认为,这并不取决于良好运作的BIOS或厂商.
L6:移动版CPU倍频设定
L6不使用在桌面版CPU上，所以是连接着的。在与主板对应的移动版CPU中,L6起着标称倍频的作用. L6还涉及到PowerNow!技术.
