I'm using '-O0 -g3 -no-pie' for builds that I use to debug issues and
'-O3 -no-pie' for builds that I use for daily work. If I were to change
this (involving some 50 builds on various machines and partitions) I
would need to be convinced that the new options would not change
anything when running the debug builds and would not slow down anything
when running the optimized builds.

It offers me an overclock mode with a CPU frequency of 200 MHz and a
PCIE Frequency of 100. I also have M2 Boost disabled whatever that
means. Still no idea whether that means that I have a Black Edition.
Maybe I'll install a program called CPU-Z (or CPUID ?) to find out.
