batch-file - WMIC 命令未显示正确的值？

Question

我们使用一种产品向我们的平台报告 RAM 和 CPU 等审计信息。

但是，当涉及到 RAM 时，我们得到了不同寻常的结果。

产品使用命令：wmic computersystem get totalphysicalmemory

输出值为 2.3GB RAM

但是它安装了4GB。我们使用这些信息为我们的客户创建路线图，因此需要准确。知道为什么吗？

wmic memorychip get capacity

使用 Hybrid [batch-Vbscript] 文件，您可以执行以下操作：

@echo off
Mode 55,10 & color 0A
Title TotalPhysicalMemory ^& Memorychip Capacity
Set "WMIC_TOTMEM=wmic ComputerSystem get TotalPhysicalMemory /format:Value"
Set "WMIC_Capacity=wmic memorychip get capacity /format:Value"
Set "CAP=Capacity"
Set "TOT=TotalPhysicalMemory"
Call :GetTOTMEM %TOT% TotalPhysicalMemory
Call :GetCapacityMem %CAP% Capacity
echo(
Call :Convert %TotalPhysicalMemory% TotalPhysicalMemory_Converted
Call :Convert %Capacity% Capacity_Converted
echo   -------------------------------------------------
echo     TotalPhysicalMemory = %TotalPhysicalMemory%
echo     Memorychip Capacity = %Capacity%
