工作站z820加了个cpu后显示器不亮了

[Hweiwen1983]

加了个cpu后显示器不亮了，机器风扇很大的声音一直吹。809842@qq.com. 机器在保，cpu自己买的维修的吗？

小键盘灯也不亮，显卡风扇正常转。

下面是z820支持的CPU型号

另外，如果加下面型号的CPU，需要供电电源达到1125W

Intel Xeon  processor   E5-2687W is ONLY available with Liquid Cooling AND with the 1125W Power Supply.

Intel Xeon  processors E5-2643, E5-2637 v2, E5-2643 v2, E5-2667 v2, E5-2687W v2, E5-2690 v2 and E5-2697 v2 REQUIRE the 1125W Power Supply Option.

[坏坏的笑]

需要注意的几个问题

1.电源是否是大功率的，1125W的

2.添加的CPU需要与原来的CPU型号相同

3.添加第二CPU后，内存需要按照双CPU的插法重新拔插，如下图所示

z820 不同CPU控制不同的PCIe通道。

PCIe3 x16, qty 3 (qty 2 when optional 2nd CPU is not installed)

NOTE:
3rd PCIe x16 slot is ONLY available when 2nd CPU is installed. This is Slot #4 on the system board and is designated by a white-colored PCIe connector.
PCIe3 x16 (8), qty 1 (qty 0 when optional 2nd CPU is not installed)

NOTE:
This slot is ONLY available when 2nd CPU is installed. This is Slot #3 on the system board and is designated by a white-colored PCIe connector.

不是上述CPU，谢谢你的回答

4跟内存不是分别插2边的1和8吗

CPU不一样的话，说什么都不行

单CPU的内存插法和双CPU的插法不一样，以上面的图片为准
