    I wish to see temperature of CPU in OSD. Monitoring plugin for it.
    I read samples in SDK folder. I read FAQ and SDK.chm.
    I don`t undestand how I can create plugin for it. My experience is not enough for it :)

    CPU: Intel P4 3.0 GHz (531)
    MB: ASUS P5GDC Pro , Sensor: Winbond W83627EHF/EHG (ISA 290h) - info from Everest UE
    BIOS 1008

    If you have any K8 CPU - you can do it. But there are no plugins for Intel CPUs currently available, sorry. So you're out of luck.

    About AMD: I think, you talk about NVSU.dll (?) But my friend has Athlon 64 X2 and MB Asus M2N-E (nForce 570 Ultra) and NVSU.dll don`t work, no monitoring. Maybe, I don`t understand what is NVIDIA System Utility SMI ? Need special driver or Asus (as always :) ) created own individual monitoring system and sensors?

    I understand, you cannot create plugin for ever sensor :) , but how Everest working for all?

    My congratulations with Final Riva !

    NV plugins are for Nvidia mobo's. You would have to know programming with the SDK in order to make one for other mobo's.

    Nope, you're misunderstanding everything.

    Is there any skeleton source code for CPU temperature monitoring? I would like to implement monitoring for Core 2 Duo CPU termal diodes.

    K8 CpuCoreDiode plugin is written by third party developer and unfortunately there no public sources for it. However, RivaTuner's SDK contains sources of all the plugins included in the distributive. You can use any of them as a base for your plugin. For example, you may use CPU plugin, which performs CPU frequency and usage monitoring.

    I know that, I just wanted a simpler sample of I2C part. Never mind, will try to figure it out on my own.

    Unwinder, how do I access MSR registers? Does RivaTuner export any APIs for that purpose? RDMSR can be executed only in kernel mode.

    I should have looked there, thanks. I have a working plugin, but I still have to figure out a few things, namely Tjunction temperature (depends on CPU model). Then I will release it.

    Unwinder, what would be more proper in your opinion?

    1. To detect CPU features in DllMain and abort plugin loading by returning FALSE
    2. To detect CPU features in GetSourceDesc() and return FALSE

    ?

    Both ways are valid but the second one looks more correct for me, because the rest plugins use such logic.

    Sorry to disappoint you but as far as I know that is not possible. Older CPU's diodes are read using Super I/O chip register and there is a myriad of them available with each having different reading procedure.

    I literally hacked a quick temperature monitoring plugin for Core 2 Duo (and hopefully Core 2 Quad too). It may even work with Yonah and Core Solo.

    There may be bugs so be carefull and above all, do not try to use it on older CPUs because reading model specific registers which do not exist on your particular CPU can crash your computer and cause you to lose data.

    Good job. We'll wait for some feedback from C2D owners then put it in guru3d downloads.

    Haven't I told you that it won't work?

    How to install C2DTemp plugin

    Download C2DTemp plugin.

    Here are the instructions on how to install C2DTemp plugin:

    1. Double-click on C2DTemp.rtu in Windows Explorer and click Ok on the following dialog

    [​IMG]

    2. Start RivaTuner

    [​IMG]

    3. On the Main tab click on the first Customize... button and then on the fifth icon from the popup menu (Hardware Monitoring)

    [​IMG]

    4. Click on the Setup button in the lower right corner

    [​IMG]

    5. Click on the Plugins button in the lower left corner

    [​IMG]

    6. Place a checkmark next to the C2DTemp.dll and click Ok

    [​IMG]

    7. Place a checkmark next to the newly available data sources and click Ok

    [​IMG]

    8. That's it. Now your hardware monitor should look something like this:

    [​IMG]

    I am waiting for your feedback.
