Thanks for answering that! I figured it would be the case, but in the bios for the OPT header it just says N/A. Never mind, it seems to be doing the job!
Quick noob question about overclocking the rig in my sig. I have read all the guides and forum posts I can find but I'm still a little confused:
I am aiming for 4.5GHz (x45 multi). Everything is on auto except that Speedstep is disabled, and I am using X.M.P. mode. I have entered a manual cpu voltage (in my case 1.230v in bios, which gives 1.224v idle and 1.216v under load) which in early testing seems fairly stable.
I would like to re-enable Speedstep and have lower power usage at idle, so as I understand it I have to use Offset voltage.
When I re-enter the bios and change from manual to offset cpu voltage, is the offset taken from my previously manually entered cpu voltage (ie 1.230v)?
The reason I ask is because when I did this, and then entered an offset of +0.005v (LLC at 50%), cpuz gives an idle of 1.280v and a load of 1.256v....
