the 8350 has 4 modules each contaning 2 cores...err more of a split core really, but its fine, it just depends on how the program views the Threads/Cores
If you look at the screen shots, it shows he's using an 8350.
Windows sometimes does this due to the AMD FX archeticture, as each "module" is 2 cores sharing resources. Which is why some OS's pick it up as 4 cores, but 8 logical threads. Don't worry though, it will still use all 8.
Virtulization just enables youto virtualise on the CPU.
CPU unlock is a feature hanging around from the Phenom II x3 days. Where if a x4 had a deffective core, it would be disabled and repackaged as a x3. So no CPU unlock would do nothing
windows is big sell out to the Intel. That is why I hate it every day more and more (Intel). All windows platforms support and are made for hyperthreading. That is intell stuff and AMD can't use that because of copyrights. So FX processors use modular cores and stuff. Which windows 7 doesn't support at all and they 'told' us the win8 will be supporting, but I can't really see it. That is why it is showing 4 cores and stuff. They are really 8 cores (do not read stuff about 4 cores and 4 imaginary like ppl use to say on some forums) and the ppl think it is quad because they made each processor share L2 cache. While intel has one core one cache L2.
