Bsod

[dhs]

2 days with random BSOD.

Uninstalled CC2. No more BSOD

I'm sorry but i can't even send a log; the bsod seems to happen before any log can be saved.

What can i do to help?

[CrystalControl Admin]

Try the new version (20060226).
This may be caused by the same DLL issue.

[dhs]

Still BSOD.

BUT, i found out it happens *only* when CC2 is reading values from SpeeFan.

If speedfan is running, no problems.
If CC2 is running, ni problems.

If CC2 is using the speedfan plugin, after a while, BSOD.

So, i think the problem lies in the SpeedFan plugin. Maybe it's not fully ok with x2 processors.

EDIT: Nope, it happened again, even without speedfan running or screens needing the speedfan plugin

[dhs]

Did some other tests today.

Looks like if i set the logging on (file_level=1) no more BSOD.

The best bugs always disappear when you turn debugging on

[CrystalControl Admin]

If speedfan is running, no problems.
If CC2 is running, ni problems.

If CC2 is using the speedfan plugin, after a while, BSOD.

Before the BSOD happens, is CC2 showing the correct speedfan information?

[dhs]

Yes (beside the fact that the latest release i can't show anymore Fan2).

I'm using SpeedFan and CC2 version 20060216 (haven't got time to upgrade yet) to read fan-speeds, temps and voltage using a P4 with HT and it works. Is your system a real dual-proc or is it HT.
I *think* that SpeedFan is using memory mapped files to communicate the values and my thought was that if your system is dual-proc then it could be that perhaps one processor (the one that originally did not execute the plugin) tries to read the mmf and causes a violation that causes the BSOD.
To test if it is processor related set affinity on the cc2_service.exe.
Otherwise run System applet from Control Panel, click on the Advanced tab, click Settings button in the Startup and Recovery section, Uncheck the checkbox for Automatically Restart and hit some Ok buttons on the way out.
Next time you get the BSOD you have the opportunity to write down the error messages and post it here and perhaps some one is able to help you.

It worked for me too with 20060216 (beside the bsod).
It doesn't read Fan02 with the latest release.

AMD64 4400 x2.

Problem is that BSOD happens even when SpeedFan isn't running and CCD isn't using the speedfan plugin.

I will. Thanks

To test if it is processor related set affinity on the cc2_service.exe.

BTW, how do i do this?

[dhs]

Attacched: logs and ini from the last crash.

Note: you will notice that CC2 creates IDs only for some sensors in speedfan, while speedfans actually sees everything (fans 1-3, and so on).

Download ProcessExplorer (it is by the way the best program in this category) http://www.sysinternals.com/Utilitie...sExplorer.html
Run it and right click on the cc2_service.exe (it is listed under System in the tree view) and choose Set Affinity..., uncheck any of Cpu 0 or Cpu 1. Unfortunately this has to be done every time you reboot your system.
This procedure will not work with windows taskmanager since you get permission denied when trying to set affinity...

I'll check and see if there is an Win32 API to set affinity on processes or if someone has solved this problem allready.

Perhaps there is a way to set affinity when the service is installed, but I leave it to CrystalControl Admin to check it up.

Ok, i tried to set the affinity (only on cpu0), started CC2 and after some seconds, bsod

TRAP_CAUSE_UNKNOW

STOP: 0x00000012 (0x00000001, 0x0000b080, 0x00000000, 0x00000000)

[meklubba]

According to my Visual Studio Documentation there is such a function. I'll check into it later, I can not promise when.

Since it works for me with HT, which isn't really dual CPU since, as I've understood it, it is the instruction streams that is splitted into two inside the CPU, but the two simulated CPUs still share the same caches. With dual proc you have separate caches which introduces cache coherency problems. Further more you get accessing issues to RAM, Virtual memory and internal busses amongst other. It could be related. I did a quick search with google and found other that had experinced the same problem but with other programs.

I'll get back here if and when I have something I think is usefull...

I'll have to go, but that indicates hardware - driver compatibility problems.
