Anil V Dharans Benchmark for the 3939k

shows core conflict in the first test - Logical processors found "12" for the "6"

You have to go into the bios and disable Hyperthreading to get logical processors down to 6!!!

Once again - Logical processors found:12

Processors to use 12

I have not read the entire thread, so this might have already been mentioned, but I use Process Lasso to disable HT when it's not available in BIOS:

BTW, after the July 10 2013 update, I started to have a "nag" screen when booting, so that's the version I use. I'm not sure if that was implemented for all versions after that, or just for those using the free version after a certain time.
