C#

ConnectionOptions connection = new ConnectionOptions(); 
connection.Impersonation = ImpersonationLevel.Impersonate;
ManagementScope scope = new ManagementScope("\\\\.\\root\\CIMV2", connection);     
scope.Connect(); 
ObjectQuery query = new ObjectQuery("SELECT * FROM Win32_PhysicalMemory");  ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query);  foreach (ManagementObject queryObj in searcher.Get()) 
{    
System.Diagnostics.Debug.WriteLine("-----------------------------------");     System.Diagnostics.Debug.WriteLine("Capacity: {0}", queryObj["Capacity"]);     System.Diagnostics.Debug.WriteLine("MemoryType: {0}", queryObj["MemoryType"]); 
}

Win32_PhysicalMemory class [^]

i want to know it is DDR1, DDR2 or DDR3

nika2008 5-Sep-12 2:38am

check the link u have all type u need
string BankLabel;
uint64 Capacity;
string Caption;
string CreationClassName;
uint16 DataWidth;
string Description;
string DeviceLocator;
uint16 FormFactor;
boolean HotSwappable;
datetime InstallDate;
uint16 InterleaveDataDepth;
uint32 InterleavePosition;
string Manufacturer;
uint16 MemoryType;
string Model;
string Name;
string OtherIdentifyingInfo;
string PartNumber;
uint32 PositionInRow;
boolean PoweredOn;
boolean Removable;
boolean Replaceable;
string SerialNumber;
string SKU;
uint32 Speed;
string Status;
string Tag;
uint16 TotalWidth;
uint16 TypeDetail;
string Version;
check what u need from this and just put it on

queryobj["somthink"];

C#

ConnectionOptions connection = new ConnectionOptions(); 
connection.Impersonation = ImpersonationLevel.Impersonate;
ManagementScope scope = new ManagementScope("\\\\.\\root\\CIMV2", connection);     
scope.Connect(); 
ObjectQuery query = new ObjectQuery("SELECT * FROM Win32_PhysicalMemory");  ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query);  foreach (ManagementObject queryObj in searcher.Get()) 
{    
System.Diagnostics.Debug.WriteLine("-----------------------------------");    
System.Diagnostics.Debug.WriteLine("Capacity: {0}", queryObj["Capacity"]);     System.Diagnostics.Debug.WriteLine("MemoryType: {0}", GetMemoryType(Int32.Parse(queryObj["MemoryType"].ToString()))); 

}

following is method which differentiate between DDR1,DDR2,DDR3 you can check other types on
WMI Physical Memory Types[^]

C#

public string GetMemoryType(int MemoryType)
        {
            switch (MemoryType)
            {
                case 20:
                    return "DDR";
                    break;
                case 21:
                    return "DDR-2";
                    break;
                default:
                    if (MemoryType == 0 || MemoryType > 22)
                        return "DDR-3";
                    else
                        return "Other";
                    break;

            }
