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 NOT recommended.
Doing so COULD 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 WILL be a rock, once again.
Do this at your own risk and only if you know what you are doing.
Project overview
Project
.NET Version[s]
RAMSPDToolkit RAM SPD functionality for your software / application. Also includes various SMBus implementations for Windows and Linux. Depends on WinRing0Driver.
.NET Framework 4.7.2 & 4.8.1 .NET 8 & .NET 9
WinRing0Driver WinRing0 driver implementation and binaries. This is required for RAMSPDToolkit.
.NET Framework 4.7.2 & 4.8.1 .NET 8 & .NET 9
ConsoleOutputTest Example Application to show how some library functionality can be used.
.NET 8
GZipSingleFile Small ("internal") console application used to zip driver files.
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 before loading driver
if (OperatingSystem.IsWindows())
{
//Load WinRing0 driver - this extracts driver files and loads them
if (!DriverManager.LoadDriver())
{
Console.WriteLine($"***** DRIVER ERROR *****");
Console.WriteLine($"-> OLS Status Code: {DriverManager.Ols.OLSStatus}");
Console.WriteLine($"-> DLL Status Code: {(OLSDLLStatus)DriverManager.Ols.GetDllStatus()}");
Environment.Exit(1);
}
else
{
Console.WriteLine("***** Driver is open *****");
}
}
//First, go through available SMBuses
foreach (var bus in SMBusManager.RegisteredSMBuses)
{
//Go through possible RAM slots
for (byte i = SPDConstants.SPD_BEGIN; i <= SPDConstants.SPD_END; i++)
{
//Detect what kind of RAM we have
var detector = new SPDDetector(bus, i);
//We have a RAM stick here
if (detector.IsValid)
{
if (detector.Accessor is IThermalSensor ts)
{
//Get temperature, if possible
if (ts.HasThermalSensor && ts.UpdateTemperature())
{
//Output temperature for detected RAM sticks
Console.WriteLine($"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.UnloadDriver();
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.
