CPU is the 64c oem version. Motherboard is H12SSW-iN.

Yeah, turbostat was reporting frequencies of 3800 MHz (all core) consistently under load. No throttling, but cpu voltages were getting a bit high (1.4+v when clocked higher than 4000MHz).
Regarding the power draw it seems to reach 300w or higher when setting OC to 3800+ and running a full load. Power draw statistics were obtain using turbostat. The cpu thermals I was seeing was low to mid 70s. Also IMPI was reporting vrm temps at high 60s.
Hmm, the UOPS_EXECUTED.CORE_CYCLES_GE_XXX events seem to do what you think it does. The percentages do add up pretty close to 100% in your second post (~99.7%). The 5% difference from your first post is probably due to noise? Vtune is taking samples so some noise is probably expected.
This was the command I used for the overclock
sudo ./zenstates.py --no-gui --oc-frequency=3400
The system is running linux. I don't think Corona bench 1.3 is supported? However I did notice that performance is actually lower when overclocked (compiling some projects, bench-marking y-cruncher)...
Very nice work to everyone involved! I'm surprised you were able to get that much more perf from those early 64c ES. Is this currently supported on windows only or can existing tools on linux be modified to make OC work?
