Access to Intel(r) Performance Counter Monitor has denied (no MSR or PCI CFG space access) message is showing with pcm-memory.x

Jump to solution

Hello, i am jerry 

I am trying to run the pcm-memory.x and pcm-power.x on windows platform with WinRing0X64.dll and sys driver files instead of recompiled msr.sys. 

By the way, pcm-win.x is running well but pcm-memory and power tool have some problems to run them.

they are alway showing below messages 

for pcm-memory.x

In case of pcm-power.x, my CPU(i74790) seems to not be supported because of non-xeon series.

By the way, i am not sure for pcm-momory.x. I think it should be running well. 

Do you have any ideas for this?  

Once message "Access to Intel(r) Performance Counter Monitor has denied (no MSR or PCI CFG space access)." looks like

my CPU can not get access to Specific MSR register and PCI CFG bar with MMIO since my CPU don't have these kinds of feature.

thanks in advance.

Hi,

pcm-memory is not supported on your processor (it does not have the performance monitoring units that the tool requires).

Thanks,

Roman
