If I remove the tick for VT-x/AMD-V activate SpeedFan works fine again.
It seems there's a collision while using the virtualisation machine.

Are you running Speedfan on the host or the guest machine(s)?
I am using VMWare, running SF in the host OS only (of course) and never encountered any problem regarding virtualization.

I'm running it on the HOST machine. Because I want to measure real temperatures.
Has VmWare a setting where you can choose using the VT mode of the CPU or not?

But it might be that this malfunction depends on my hardware type (e.g. chipset).
I've an ASUS P5N-E SLI with an Intel Core2Duo E6400 and 4 GB RAM.

Kind regards,
Andreas

I have the same problem. Only occurs when the VT-x/AMD-V box is checked. Reported this to VirtualBox as well: http://www.virtualbox.org/ticket/988 [^]

But there no solution has been posted yet either...
Annoying little problem...

Ah, maybe relevant information:

I have an Asus P5B Deluxe motherboard...maybe this is only an Asus problem?

I have the same motherboard. I will try to find some time to check it, but I would ask Virtual Box because it seems specific to that tool.

Alfredo, here is the situation with VirtualBox (So you can replicate the problem):

Speedfan is running, when I then start VirtualBox everything is ok until I start a virtual computer, lets say Windows XP. The virtual windows computer starts up as normal, but as soon as the windows logo appears speedfan gives 00 as temperature. If you then stop speedfan, and start it again you get an error message. In my case: Access violation at address 00620EF2 in module 'speedfan.exe'. Read of address FFFFFFFF.

I don't think this is a speedfan, nor a virtualbox problem, I think this is more a memory collision, because both programs work fine when the other isn't running.

Uploaded another file with the info that speedfan gives me after all the temperatures have gone to 00

I have the same problem: SpeedFan works fine until VirtualBox is turning on. After this, reads from SpeedFan stucks into "00" and if you try to restart then you get a "access violation" error from speedfan... Maybe the virtualbox gets exclusive access to CPU or to yours sensors?

Ok. I installed VirtualBox 1.6 on my Windows Vista Business. I have an Asus P5B Deluxe with an Intel E6420 and 2GB RAM. I installed Windows XP Pro in VirtualBox and enabled VT-x/AMD-V. I've seen the access violation. The solution is to stop GIVEIO.SYS service. SpeedFan 4.35 beta will include a new command line parameter (/NOGIVEIO) to start SpeedFan without any access to the GIVEIO service.
