ASUS P8P67 Pro/Evo/Deluxe OC discussion thread

Voltage will not drop if you set a manual voltage, only way to get it to track processor speed is by using the offset mode.

Also, could you (or anyone) explain the offset mode exactly? I looked in the book, but it doesn't really say too much. Maybe this has already been explained somewhere on the forum. I'll look around as well.

Thanks.

I know the theory, but not the way it really works. Offset just adds (or subtracts) whatever voltage you specify to the base voltage. So if the base voltage is 1.2 and you need 1.4 for your overclock, you would specify a +0.2 offset. Problem is knowing what the base voltage is, and I haven't seen anywhere that spells that out - so I think it is trial and error where you have to set an offset, then check, then change the offset, and repeat.

Since I can't get mine to sleep above 4.5Ghz, I am just using Auto for now, and it works as advertised - a little high on the load voltage, but nice and low at idle.

I see...thank you very much for the explanation.

Trying to decide between the Pro or Deluxe for my OC/gaming rig.

Wont use any of the additional features on the Deluxe, and will likely do crossfire later on.

It's $100aud diff between the two...so really, when does the 16phase help? I really wanna get a 2600K as close to 5ghz.

Will a Pro suffice?

But it really depends on the 2600K cpu you get from what I read on another forum where a Asus rep posted basically saying that -----> Expectations regarding K series overclocking in general and on ASUS P67 motherboardsPrior to the recommendations on overclocking the K series, I am outlining our results to set expectations.
The results below are based on the range of the CPU turbo multiplier when overclocking.
Results are representative of 100 D2 CPUs that were binned and tested for stability under load; these results will most likely represent retail CPUs.
1. Approximately 50% of CPUs can go up to 4.4~4.5 GHz
2. Approximately 40% of CPUs can go up to 4.6~4.7 GHz
3. Approximately 10% of CPUs can go up to 4.8~5 GHz (50+ multipliers are about 2% of this group)

Hope you are one of the 10% or 2% which finds that golden cpu..

They might've been talking about the auto OC feature? Or some arbitrary voltage ceiling? Much more than 10% of the CPUs I've seen can do 4.8+

Hi, I have my 2500K stable at 4,8Ghz, he made it thru 4,9Ghz but I needed to give him more cpu voltage, wich I'm not confortable with...

The problem is, that after all tests he's stable, but when I turn it on the next day, the mobo doesn't turn on, it just reboots 2x times and the EFI gets the cpu in stock mode.

Does this happen to anyone? Or is it just me?

Thanks


EDIT: Sorry, didn't saw this thread

Anyway is it true that 1,35v is the maximum safe voltage for the Sandy cpu's?
