RAMSPDToolkit-NDD 1.1.4

RAMSPDToolkit

A toolkit for accessing RAMs SPD. Primarily used for reading temperature and data from SPD.<br/> Reading from SPD is standardized by JEDEC, for the most part.<br/>

Warning - writing via SMBus and to SPD is dangerous

It is possible and supported to write data via SMBus, but NOT recommended and dangerous for your hardware.<br/> You can also write data to the SPD via SMBus, when write protection is disabled, which is also NOT recommended.<br/> Doing so COULD brick whatever hardware you're writing to, rendering that hardware part useless.<br/> Writing to something you should not write to means: this piece of hardware WILL be a rock, once again.<br/> Do this at your own risk and only if you know what you are doing.

Feel free to give feedback and contribute to our project !<br/> Pull requests are welcome. Please include as much information as possible.

Developer information

Integrate the library in your own application

Sample code

static class Program
{
    static void Main(string[] args)
    {
        //You can enable logging and set level, if you need logging output
        Logger.Instance.IsEnabled = true;
        Logger.Instance.LogLevel = LogLevel.Trace;

        //Check for Windows before loading driver
        if (OperatingSystem.IsWindows())
        {
            //Init OLS driver
            DriverManager.InitDriver(InternalDriver.OLS);

            //Check if OLS driver was initalized and could be loaded
            if (DriverManager.DriverImplementation == InternalDriver.OLS
             && DriverManager.Driver.Load())
            {
                Console.WriteLine("***** Driver is open. *****");
            }
            else
            {
                Console.WriteLine($"***** DRIVER ERROR *****");
                throw new Exception("Driver is not open.");
            }
        }

        //Detect SMBuses
        SMBusManager.DetectSMBuses();

        //Go through available SMBuses
        foreach (var bus in SMBusManager.RegisteredSMBuses)
        {
            //Go through possible RAM slots
            for (byte i = SPDConstants.SPD_BEGIN; i <= SPDConstants.SPD_END; i++)
            {
                //Detect what kind of RAM we have
                var detector = new SPDDetector(bus, i);

                //We have a RAM stick here
                if (detector.IsValid)
                {
                    if (detector.Accessor is IThermalSensor ts)
                    {
                        //Get temperature, if possible
                        if (ts.HasThermalSensor && ts.UpdateTemperature())
                        {
                            //Output temperature for detected RAM sticks
                            Console.WriteLine($"DIMM #{i - SPDConstants.SPD_BEGIN}: {ts.Temperature}°C / {TemperatureConverter.CelsiusToFahrenheit(ts.Temperature)}°F.");
                        }
                    }
                }
            }
        }

        //Check for Windows before unloading driver
        if (OperatingSystem.IsWindows())
        {
            //Unload the driver - this removes extracted driver files and unloads them
            DriverManager.Driver.Unload();
            Console.WriteLine("***** Closed driver *****");
        }

        //Save log file to current directory, if you enabled logging output
        Logger.Instance.SaveToFile("Log.txt", false);

        //All done
        Console.WriteLine("Press enter to exit...");
        Console.ReadLine();
    }
}

Administrator rights

Some functionality requires administrator privileges to access the data.<br/> Consider adding a manifest file to your application and set requestedExecutionLevel to requireAdministrator.

Can I use my own driver ?

Yes, you can implement your own driver via our IDriver interface.<br/> You just have to assign an instance to RAMSPDToolkit and it will use your implementation instead.<br/> Please be sure to use a well tested driver.

NDD Build / Package (No Default Driver[s])

We also provide a version without any internal driver implementation or binaries. You can change compilation configuration for that or use the NDD package.
