A toolkit for accessing RAMs SPD. Primarily used for reading temperature and data from SPD.
Reading from SPD is standardized by JEDEC, for the most part.
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.
You can also write data to the SPD via SMBus, when write protection is disabled, which is also
Doing so brick whatever hardware you're writing to, rendering that hardware part useless.
Writing to something you should not write to means: this piece of hardware be once again.
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 !
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 OS and load driver
if (OperatingSystem.IsWindows())
{
//Load driver
if (DriverManager.LoadDriver(DriverImplementation.WinRing0))
{
Console.WriteLine($"***** Driver {DriverManager.DriverImplementation} is open. *****");
}
else
{
Console.WriteLine($"***** 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.
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. This can be done using our IGenericDriver interface.
If you will be using any of our pre-defined drivers you will find specific interfaces for them aswell, which you can implement.
Whatever you do, please be sure to use a well tested driver.
New driver suggestions are welcome. Please open an issue on the repository and we will check.
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.
