Virtualization you can enable under advanced > cpu configuration > SVM mode.
As far as your PC crashing in idle goes. I dont know, really. Did not have that problem with same board, CPU. I have similar g skill 3200mhz cl14 ram. For that I choose some prebuilt ram oc profile, then dialed down the voltage to 1.35v and did some minor timing changes. Thats really all I did as far as oc goes so far.
Some of the things are renamed very strangely. I didnt exactly find XFR2 for instance either. It seems to be working, although only boosting to 4.2ghz max in single theaded cinebench for instance. Only reaches 65° with some jumps a little closer to 70°. Dont really know why it does not do 4.3ghz yet. The 65°-something more close to 70 are not single threaded temps. Its max temps ever when its at 100% load. But it reaches that way before 100% load. After that fan speed changes is all.
What OS are you using though? Have you by any chance tried to use an existing Windows installation with new hardware?
