Can't run a lot of analysis on supported CPU

I'm trying to run the "Memory Access" analysis but i'm getting the following error "This analysis type is not applicable to the current machine microarchitecture."

Reading the docs here https://software.intel.com/en-us/vtune-amplifier-help-memory-access-analysis I can see that the following are supported

 

Support Limitations

Memory Access analysis is supported on the following platforms:

  • 2nd Generation Intel® Core™ processors

  • Intel® Xeon® processor families, or later

  • 3rd Generation Intel® Atom™ processor family, or later

 

This is running 2018 Update 1 (build 535340) on windows 10 with a X5650 so i'm assuming it should work as its a Xeon processor.

I'm also getting the following warning "On some systems based on the Intel microarchitecture code name Nehalem / Westmere with C-states enabled, this analysis type may cause system hanging due to a known hardware issue (see errata AAJ134 in http://download.intel.com/design/processor/specupdt/320836.pdf). To avoid this situation, disable all "Cn(ACPI Cn) report to OS" BIOS options before sampling with VTune Amplifier on such systems."

It does BSOD my machine if I run it but I have no idea how to disable. Cn(ACPI Cn) report to OS. Any suggestions ?

The documentation is not quite accurate here. Memory Access is supported on Intel® Xeon® processor code name Sandy Bridge or tater.

Your CPU is older and it is not supported.
