I'm trying to Overclock my 8350 but i donno what are these in CPU FEATURES

Core C6 State
IOMMU mode
C1E Support
SVM Mode
AMD Cool'n'Quiet

ps. can anybody tell me in what range should i change NB Voltage and CPU NB Voltage in BIOS

ok since after 6month from the original post I know everything right now and the number of reads on the thread is more than 1000 i see the need to explain them myself

in a nutshell for those who dont have the time to read them all
I overclocked my rig in a stable manner, and have all the options Enabled except IOMMU mode & SVM Mode which are for virtual machines to work better and I dont need them

in this case i dont have any problem with my overclocking, when im idle, the CPU Voltage goes from 1.4 to 0.999 which seriously helps ur bills
and this effect comes solely from Cool'n'Quiet Enabled NOT Automatic, I tested it, Automatic wont do it, Just put it to Enabled

Core c6 state let ur idle core to remain at c6 state which let ur cpu to consume less power concordantly less bills to pay
HPC mode works very close to cool'n'quite and lower ur cpu's clock instead of its voltage which helps to have less need of Voltage
C1e support works similar to HPC mode but it twiddles with the multiplier for lowering ur cpu clock
thats all I know, there are more professional details on net
hope it helped

May our only true God watch over our path
