So the main voltage I should be monitoring is only the CPU Vcore then?

Well I've never tried what you are suggesting on a Gigabyte motherboard - they do have two different settings for CPU, unlike most boards, so maybe it is actually possible. Give it a shot - if nothing else, you'd be able to see if it really does work even if you don't end up using it.

The Vcore is all you really need to worry about at those speeds. Once you start looking at 4.8+ then you'd find advantage in adjusting some of the others. As Flashfir mentioned, you can usually lower the CPU PLL a little without affecting stability, and it normally does cut the temps a few degrees.

Alright then, but just an FYI here if you don't know already: I'm not going to be touching the voltage options. I'll be leaving everything on auto and let the BIOS do the work. biggrin.gif

Oh yeah, I have another question. What is the point in OC'ing memory when OC'ing the CPU? Do I have to do this if I set TB's clock up to around 4.4Ghz?

No touch the vcore. The auto setting uses way more voltage than is required

I know the auto settings uses more than the required voltage but I don't see the harm in it as long as the voltage doesn't go past 1.36-1.40V.

You should be fine on Auto at 4.4, but be sure to check the temps. There's not a whole lot of advantage in overclocking the memory - I would just run it at the rated speed. Since you are using multipliers to overclock the CPU the memory isn't automatically overclocked like it used to be, so you can just leave it at stock.

Alright, thanks. By the way, what mode should I run 10 passes of IBT on? Standard or the Maximum/Extreme mode?

Very High or Maximum. I don't think there is any benefit in running the extreme mode (the one you get to by right-clicking the start button).

OK. I'll try maximum then.

Another question came to mind when I wanted to look at CPU-Z. The clock speed/multiplier varies at x37 to x38 (3.7 to 3.8Ghz) at idle while the voltage is at around 0.700 to 0.800V. Is this normal? I thought the BIOS was supposed to down clock the CPU to around 1.6Ghz at idle? Anyway, everything works fine with it like that and it's not like the voltage is a constant 1.080V which is, according to HWmonitor, the max Vcore. However, it makes me wonder why it's not down clocking or at stock 3.4Ghz when idle.

This is just a minor concern of mine that would be nice to have an answer to before I start OC'ing. XD

P.S. - Thank you for all of your support so far. biggrin.gif

If you have High Performance set in the Windows power plan, then CPU-Z will show the full speed freq all the time. So it's probably that. Otherwise you can check the BIOS options and see if they are enabled - EIST, C1E, C3 and C6.

Huh, really? I didn't know that. mellowsmiley.gif

It makes sense though, as I do have my power settings custom on high performance. Is having power settings on high performance a bad thing?
