First of all thanks very much for the answer,

I have a question which are these two for:?

Hardware prefetcher - [disabled]
Adjacent Cache line prefetcher - [disabled]

And these voltages?

IOH voltage - [1.15v]
IOH PCIE voltage - [1.5v]
ICH voltage- [1.15v]
ICH PCIE voltage - [1.5v]

i know PCIE ones should be ones who control PCIE frec but the others? is it useful to take them in consideration while overclocking?

third and last question

temps on load with linx are in the 70s using a true push pull setup , is that ok?? or i should consider getting something better?
