机器2:25g软交换
功耗情况
整机包括:主板,e5 2650 v4,8gx2 普通内存,gt1030低功耗亮机卡,dc电源。开机进入bios后整机99瓦,进入ubuntu server后,整机待机功耗41.3瓦。
后面安装 debian 12 之后的测试,这个主板 + e5 2630l v3,dc电源。在进入系统之后
- 8gx2 普通内存,r5 240低功耗亮机卡,待机40瓦
- 8gx2 普通内存,不插显卡,无头模式进入系统,待机34瓦,也就是r5 240低功耗亮机卡大概是6瓦的待机功耗
- 将内存从8gx2 普通内存换到16g x 4 的 reg ecc 服务器内存,待机54瓦,也就是每条 16g reg ecc 服务器内存需要5-6瓦的功耗
- 继续用8gx2 普通内存,不插显卡(基础功耗为34瓦),增加一块cx4121a网卡,待机功耗增加到44瓦,也就是一块cx4121a网卡大概要10瓦待机功耗。
bios设置
为了尽量降低整机功耗,需要的bios设置:
“M.I.T.” -> “Advanced Frequency Settings” -> “Advanced CPU Core Settings”
- Hyper-threading technology: disabled
- cpu enhanced halt (c1e): enabled
- c3 state support: enabled
- c6/c7 state support: enabled
- cpu eist function: enabled
“C hipset”
- Audio controller: disabled
- PCH internal Lan: disabled
- Intel VT for Directed I/O(VT-d): enable
- execute disabled bit: enabled
- intel Virutalization Technology(vt-x): enabled
机器硬件
cpu 用的是 e5 1660 v3,超全核4.5g,cpuz测试成绩如下:
内存用的是海力士 reg ecc 内存,ddr4 2133,afr 颗粒,四条单根4g内存组成4通道16g。

Cas Latency = 16
tRCD = 20
tRP = 20
tRAS = 40
rRFC = 660
Command Rate(tCMD) = 2 要不要改成1t?
tREFI = 30000
Channel B/C/D 同样设置。
M.I.T. -> “Advanced Voltage Settings” -> ""
DRAM Voltage (Ch A/B) = 1.40v
DRAM Training Voltage (Ch A/B) = 1.40v
DRAM Voltage (Ch C/D) = 1.40v
DRAM Training Voltage (Ch C/D) = 1.40v
主板bios超频设置2
技嘉x99 ud4 主板 + e5 1660 v3 cpu + 英睿达内存8gx4.
基本设置
风扇设置
“M.I.T.” -> “smart fan settings”
- “cpu”: silent
- “2nd System”: 用来给网卡、ssd进行散热,因为风扇转速低,因此需要设置为 “Full Speed”.
虚拟化支持
“chipset”
- 设置 “Intel VT for Directed I/O(vt-d)” 为 enabled
- 设置 “Intel Virtualization Technology(vt-x)” 为 enabled
顺便关闭主板自带的声卡和网卡:
