1.376v is what I need in cpuz at load. That's what most people mean when they tell you their voltage.

What is this Power limit % you speak of?

ASUS motherboards have an option in the bios called CPU Current Capability. Setting this to 140% lets the system use up to 40% more power at load than it would by default, which allows more performance at higher overclocks, since the processor doesn't have to slow itself down due to reaching its power limit.

Does this mean I get to say my chip can do 4.4GHz @ 1.309v even though I need to set vCore to 1.395v?

Yeah, basically. I use offset voltage and not manual, so my voltage goes down to around 0.9v at idle and only goes up to 1.376v at load.

What % do I need for 45x OC?

What would be the equivalent of offset voltage overclocking on gigabyte motherboards?

Apparently I have to set vCore to Normal and then adjust the Dynamic vCore.
I'll have to look into that some other time.

But if anyone would like to save me the work
What would setting be the equivalent of getting to ~1.310v at load using DVID?

Also how would I set the 'power limit' on a Gigabyte board?
would it be a smaller scale of something like this?
Quote:
B.If not already using turbo options, please do so. Now set upper limit on TDP and TDC at 200-300 to removed TDP and TDC limitations. If your board has OCP (over current protection) you can disable this if you want a very high overclock.

From Sin's OC guide.

The main reason I can see is if you're using manual voltage and don't want your idle voltage to be high.

For example, if you need 1.4v at load and set your voltage manually, you may need need 1.5v in the bios to end up at 1.4v load (due to vdroop). This means your system will probably idle near 1.5v, which a lot of people don't want.

In this case, LLC lets your voltage stay near 1.4v at all times, which lowers heat, power usage, and probably increases processor life.

However, if you're using offset voltage, your voltage will drop to 1v or under at idle, so LLC doesn't bring much benefit here. I'd mainly use it in this case if it helped me get stable at a lower vcore, which I haven't found to be the case on a decent motherboard @ less than 1.4v.

I'd just set it at 140%, which is what ASUS reps have recommended for overclocking. 45x probably won't need 40% extra power, but that setting just sets the maximum power limit--not how much power it will actually use, so with it at 140%, you won't have to worry about the power limit holding your overclock back.

Gigabyte calls it dynamic vcore, and it's located under the cpu vcore option in the bios.

Cheers for the reply munaim1 it will run the fft tests no prob with those settings you showed me and the temps are 59-62 on load but thing is soon as i try run a blend torture test on prime it blue screens straight away wth.gif
so any tips too help me stabilize 5ghz would be greatly appreciated

current BIOS settings as follows

clcok ratio - x51
BCLK ratio - 99.7
PLL overvoltage - enabled
turbo boost and real time ratio changes in OS - both disabled
(C1E) - disabled
C3/C6 state - disabled
cpu thermal monitor - disabled
EIST Function - disabled
PROCHOT - disabled

multi steps load line - level 9
Vore *normal 1.395V* *Current 1.440V*
PLL voltage is 1.8 as of now but was at 1.74 before

if theres any settings you want to know that aren't there please let me know

cheers
Ryan.

edited my previous post after some quick searching on the forums.

another thing I'm interested in exploring is ehume's method of dropping the vCore in idle with power saving options.
Quote:
If you really would like to see your Vcore drop, try this:
Control Panel > Power Options > High Performance > Change Plan Settings
Change advanced power settings > Processor power management > Minimum processor state >
Something small (I have mine at 2%, but 5% will do)
This will allow your voltages to drop when EIST is enabled.
So enable EIST and watch your temps drop. It's fun.
And your Vcore will still rise up to meet demand when it is needed.

But it seems to me that that is more or less what offset does.

So it's more of a liability than an asset when you enable LLC while using Offset?

For me it was because (on ASUS p8p67 boards) you usually have to disable c3 and c6 reporting to stop BSODs at idle when you're using higher LLC levels and offset voltage.

Disabling these doubled idle cpu power usage because I guess the processor wasn't able to utilize the deeper sleep states for idle cores, so by disabling LLC, I was able to leave c3 and c6 reporting enabled and save some power.

I've also heard disabling c3 and c6 reporting hurts hard drive performance, but I haven't tested that first hand.

I have no issue with BSODs on idle and I use offset and high or Ultra High LLC smile.gif

Yea, I tested the C3 AND C6 states to see the performance and enabled gave me like 5% better performance or so.

I see you're using a p8z68, so I guess it's a problem with ASUS's p8p67 boards.

I'm sure asus could fix the problem with a bios update, but they've basically stopped updating our bioses, so I won't be counting on that.
