How to query physical memory chips using SMS hardware inventory

The question about how to inventory physical RAM chips installed on SMS clients seems to come up a lot. I've created this blog post to create a centralized location for the answer to this question. Anyway, the MOF edit I use for this is below. If you modify this extension be sure to take note of the compound key (Tag and CreationClassName) and array designator [] for DeviceLocator--leave those in the edit or you will have issues...trust me. The SMS_Units property I added is just to make the information more 'human friendly' when displayed in Resource Explorer.

 

[SMS_Report (TRUE),
SMS_Group_Name ("Physical Memory"),
SMS_Class_ID   ("Microsoft|Physical_Memory|1.0")]

class Win32_PhysicalMemory : SMS_Class_Template
{   
                [SMS_Report (TRUE)] string BankLabel;   
                [SMS_Report (TRUE), SMS_Units("Megabytes")]  uint64 Capacity;   
                [SMS_Report (TRUE)] string Caption;   
                [SMS_Report (TRUE)] string DeviceLocator[];   
                [SMS_Report (TRUE)] uint16 FormFactor;   
                [SMS_Report (TRUE)] string Manufacturer;   
                [SMS_Report (TRUE)] uint16 MemoryType;   
                [SMS_Report (TRUE)] uint32 PositionInRow;   
                [SMS_Report (TRUE)] uint32 Speed;   
                [SMS_Report (TRUE),Key] string    Tag;   
                [SMS_Report (TRUE),Key] string    CreationClassName;
};

 

Hope this helps,

Hi Jeff.  When implementing this edit; 1 company noticed that changes were not being correctly reflected unless they had the pragma deleteclass.

#pragma namespace("\\\\.\\ROOT\\CIMV2\\SMS")

#pragma deleteclass("win32_PhysicalMemory",NOFAIL)

That most likely means that the class was already there from an earlier attempt. You should only need the #pragma deleteclass line if you've changed something in the edit and need to totally re-create it.

Jeff,

Thanks for this: it was just what I was looking for.

One question.  Is there a way that I can get this information into a report?

Here you go, just save this as a .mof and import it into your reports. Watch for word wrap here and make sure all the comments start with //. I've picked a couple values more or less from random that look good to me for this report. More information about the values returned can be found on MSDN for this class--I've put the link in the report comments.

Jeff,

That's absolutely fantastic.  I had to edit a couple of lines to get the MOF file to import(specifically removing the ReportGUID and UnicodeData lines) but after that, it worked perfectly.

Really appreciate you taking the time to get back to me.
