南北桥的供电测试点

<TABLE class=t_msg cellSpacing=0 cellPadding=4 border=0><TBODY><TR><TD class=line style="PADDING-TOP: 10px" vAlign=top height="100%"><SPAN class=bold>南北桥的供电测试点</SPAN><BR><BR><DIV class=t_msgfont id=message5020>很多刚开始搞的朋友都说找不到南北桥的供电点,现以MS-6580实物为例子,以上两图分别为NB、SB，他们的供电点可以通过在桥旁边的小电容来丈量，小电容一般一端接地，另一端就是供电端。如北桥的CB115 、C80、CB107、CB109、CB110这些小电容的一端都跟CPU的VCORE相连，CB129是5V，L12和C72是跟内存供电相连的2.5V，南桥的供电测试点也多是在电容脚上.至于怎么会知道这些,实在没什么好方法,多量实物,想办法多搞些电路图看一下,假如能找到跟手上板子相同的电路图,一定一定一定对照图把板上每个元件的作用搞清楚!!!!!!!其它不同型号的板要举一反三,熟能生巧了,到时你想不成高手都难.看完这些东西心情激动吧,哈哈!不到之处请各位多指正批评.&lt;/font&gt;<BR><BR>[<I> 本帖最后由 断箭 于 2007-4-28 23:21 编辑 </I>]</DIV><BR><FONT style="FONT: 12px Tahoma, Verdana; COLOR: #050505"><BR><BR><DIV class=msgbody><DIV class=msgheader><DIV class=right><A href="http://www.chinafix.com.cn/bbs/member.php?action=credits&amp;view=getattach" target=_blank><IMG alt=查看积分策略说明 src="http://www.chinafix.com.cn/bbs/images/default/credits_attachlist.gif" border=0></A></DIV>附件</DIV><DIV class=msgborder style="PADDING-RIGHT: 0px; PADDING-LEFT: 0px; PADDING-BOTTOM: 0px; PADDING-TOP: 0px; BORDER-BOTTOM: 0px"><DIV class=t_attachlist><DIV class="right smalltxt">2007-4-28 23:21<BR></DIV><IMG class=absmiddle alt="" src="http://www.chinafix.com.cn/bbs/images/attachicons/image.gif" border=0> <A class=bold href="http://www.chinafix.com.cn/bbs/attachment.php?aid=1701&amp;nothumb=yes" target=_blank><U>NB.jpg</U></A> <SPAN class=smalltxt>(115.11 KB)</SPAN> <BR>&nbsp; <BR><IMG onmousewheel="return imgzoom(this)" onmouseover="attachimg(this, 'mouseover')" style="CURSOR: pointer" onclick="attachimg(this, 'click', 'attachments/20070428_a994b162efcd74696defnnnBvBW5WsLV.jpg')" alt="点击在新窗口查看全图&#10;CTRL 鼠标滚轮放大或缩小" src="http://www.chinafix.com.cn/bbs/attachments/20070428_a994b162efcd74696defnnnBvBW5WsLV.jpg" width=716 border=0 resized="true"> </DIV><DIV class=t_attachlist><DIV class="right smalltxt">2007-4-28 23:21<BR></DIV><IMG class=absmiddle alt="" src="http://www.chinafix.com.cn/bbs/images/attachicons/image.gif" border=0> <A class=bold href="http://www.chinafix.com.cn/bbs/attachment.php?aid=1702&amp;nothumb=yes" target=_blank><U>SB.jpg</U></A> <SPAN class=smalltxt>(135.13 KB)</SPAN> <BR>&nbsp; <BR><IMG onmousewheel="return imgzoom(this)" onmouseover="attachimg(this, 'mouseover')" style="CURSOR: pointer" onclick="attachimg(this, 'click', 'attachments/20070428_c0461513d1b4acd48a37KXnLd3l1kIWB.jpg')" alt="点击在新窗口查看全图&#10;CTRL 鼠标滚轮放大或缩小" src="http://www.chinafix.com.cn/bbs/attachments/20070428_c0461513d1b4acd48a37KXnLd3l1kIWB.jpg" width=716 border=0 resized="true"> </DIV></DIV></DIV></FONT></TD></TR><TR><TD vAlign=bottom><BR></TD></TR></TBODY></TABLE>
