4.) Is it recommended NOT to change BCLK?

5.) Why is "per core" setting not recommended by many? Does it affect the overclocking potential of the CPU?
1) It's mostly going to be 1600Mhz and overclock. I do sometimes see odd numbers like 2.0GHz, 3.0GHz, etc. But for the most part those are the 2 you'll see.

2) Enabled. It's required for the downclocking to function correctly.

3) Yes, VRM Frequency should be 350Mhz for best results.

4) Yes / No. I was running 105MHz BCLK for my overclock. I just bought a SSD though, and I've heard that BCLK changes are tempramental with SSD's, so I'm back to 100MHz for now till I can test that. Feel free to toy with BCLK if you're bored...but if you have a SSD, use at your own risk.

5) Per core will just make things that much more difficult in testing.

Not with Sandy Bridge. It's not better than Prime95, so all it really does it generate more heat for no reason.

My frequency and core voltage dynamically adjust based on load. Although I think the CPU frequency is always either 1.6GHz (idle) or 4.8GHz. I mean, it seems that even a SMALL amount of load ramps it up to 4.8 GHz even though the core voltage adjusts to all sorts of different amounts based on the CPU load.

Enabled if you are not adjusting the BCLK, and disabled if you are adjusting it. Spread Spectrum has something to do with reducing EMI. Disabling it helps make BCKL overclocking easier because it frees up that system resource. Therefore, leave it enabled if you are leaving the BCLK at 100.0 MHz.

Using 350 allows for scaling to a multiplier of 50 and beyond without issues.

It's absolutely up to you, but I prefer to leave the BCLK alone so that my memory stays at 1866MHz. Plus, it enables me to have an easy time overclocking. Adjusting the BCLK complicates this (but that is more fun for some people).

Because it's not necessary. Some people prefer being able to individually adjust the cores, but not me. I don't have a reason to.

Besides, if I try to have a different multiplier for even one of my cores, then that makes stress testing much more complicated.

Alright so I finally got my parts and got them set up but I have a couple of doubts/problems:

First of all I am getting the double/triple boot post problem a couple of people have been reporting and I remember hearing there was a fix for this but I thought this problem would go away with the new GEN3 boards.

Another thing I want to ask is if the following temps look normal as I remember my old AMD Phenom running around 27-28 at idle when OC'ed and I'm currently running my i5 stock and it seems to be a bit higher.

One last thing anyone know what that CPUTIN reading is? 60 C seems way to high.

I'm not sure if i5s actually run warmer or if the sensor is just in a different place, I think it's the latter, but it's normal to see temp readings quite a bit higher for i3/i5/i7 chips. My old Phenom 720 idled at 20 and P95d at 42, my i5 idles at 30-35 and P95s at 70-80 depending on my OC (still fiddling around). I don't think the i5 ACTUALLY runs twice as hot (sure doesn't feel like it putting my hand to the exhaust/on the heatsink).

So yes it's normal and nothing to worry about.

As for double/triple boot, enabling power on via PCI-E has lessened the frequency, but it still happens to me occasionally. Manually setting the ram frequency/timing profile is also supposed to help, but it didn't work for me.

But, "does it really matter?" is the question. 2.0 cards don't even utilize their full bandwidth, which has been talked to death about, so 3.0 seems more of a marketing gimmick now more than anything.

That's what I figured. Even if Nvidia/ATI release PCIe 3.0 cards, it won't matter since PCIe 2.0 speeds haven't even been saturated yet. I guess us without those 'Gen3' boards don't really have anything to worry about, plus the previous boards are cheaper anyway.

Thanks for the reply, forgot to mention room temp is around 24-25 degree. I live in Puerto Rico so I assume it's gonna be a little hotter.

EDIT:

Just played a round of BF3 and temps have stayed around 44-46 C so I guess I'm good for the moment. Get around 60 fps with everything on high and the textures on ultra. This processor is amazing even at stock speeds.

Right now on newegg, the Gen 3 version of the Asus P8Z68-V Pro is cheaper than the non gen3 by $10. Strange. I have one on the way.

That is pretty weird, I'm pretty sure the non-gen3 was 195 when I bought my gen3 on Sunday.

Can I join the club? I have a P8Z68-v Pro/GEN3

I bought it before Newegg could notify me that it was available :3

Ok.

Why are there duplicate settings in the UEFI? Like EIST, it is available in CPU Power Management under AI Tweaker and also in CPU Configuration tab. Same as with Turbo Ratio. What will happen if I set my Turbo Ratio Multi in the CPU Configuration tab and not in AI Tweaker?
