I don't think there is,basically from what i understand using offset is basically like using adaptive except u set your own offset instead of the mobo doing it. Everything i've read says u should use adaptive instead,they say it is more efficient. It is what i use and it works great

Usually it's actual vcore, or pretty darn close! Should always be a bit higher than the vcore reading in HWMon.

If you are using the low power C6 or C7 state in Haswell, voltage automatically drops to virtually zero. There is no need to use offset voltage if you have all of the C States enabled. C States can save far more power than using offset voltages.

You can use RealTemp T|I Edition if you want to see what C States your CPU is using. It's always a good idea to make sure your motherboard bios selections are working properly.

Oh amazing I had no idea there was a new version of RealTemp, I love this one! Now here is my question!

I'm curious how I should mess with my C States in the BIOS this is what RealTemp is showing me:

post #7545 of 19637
The way these Intel CPUs work is that individual cores can drop down to the low power C States like C6 and C7 and once all the cores are in the same C State, then the entire CPU package can also drop down to the same low power C State for further power reductions. If you look at my screen shot, you can see that my 3570K is using the individual core C States as well as the CPU Package C States.

RealTemp shows your individual cores are using the low power C7 state but the entire CPU package C States are disabled and not being used. You can have a look in the bios to see if you can enable these for further power reductions. I was helping one user that had this option in the bios but it only enabled the C2 Package C State and nothing deeper.

I released the T|I Edition over a year ago and created a new thread for it in the Intel CPU section but it got shuffled off to the Other Software section where no one can find it.

http://www.overclock.net/t/1330144/realtemp-t-i-edition

It's one of the very few tools available that can show you what your CPU is really doing. Give that old thread a bump if you have any questions. Closely watching the C States is a great way to track down all of the background crap running on your computer. Over 99% in C6 or C7 is a great number to shoot for. Some drivers are poorly written so they can interfere with the C States.

Hey folks,

I'm just curious what should be expected about the haswell's temps at stock clock on Prime95 or similars using heatsinks such like the Hyper 212 or the H100.

I was googling somewhere and I found folks complaining about their stock temps during a stress test using the H100.
Is it normal to see stock temps at 60C range during a stress test for a H100?

I would say yes

Share my new settings.

IBT make my temp reached 93c. I might change my thermal paste from mx-4 to liquid pro to get a better temp.



Settings :
4770K L316B828 Malaysia
CPU/Cache : 47/47
Vcore/Vcache : 1.296v/1.310v Bios (error reading on HWMonitor 1.342v)
CPU input voltage : 1.94v
SA : + 0.250
Others : Auto
Memory : Patriot Viper 3 Red 2x8gb 2133 11-11-11-30-2 1.5v @ 2600 12-13-13-27-1 1.65v
Cooling : Single loop 420 rad push/pull with EK WB Supremacy Nickel

Cheers

Could really need some help now. I have been trying a lot lately but can't really get any stable clocks. mad.gif
I want to try to get it to 4.4Ghz stable and after that maybe go higher if my temps allow it.
But right now it seems impossible to get it running. It always crashes when starting up or at desktop, even if I crank the volts up where I consider it high. So I don't really know what to do now.

The last overclock i tried was:
CPU Ratio: 44
Ring Ratio: 34
DRAM Frequency: 1600Mhz
X.M.P: Enable
DRAM Timing Mode Link
Vdroop: +25%
Vcore: 1.3v
VCCIN: 1.9v
DRAM Voltage 1.5v

I have also tried with even higher, vcore, vccin, ring voltage and both higher and lower ring ratio.
So now I'm clueless on whats causing the crash. I'm getting the BCCode: 124, btw.
Only clock I get stable is the OC genie at 4.0ghz, lol.
I can take some screenshots of my bios settings if that helps.

Use manual instead of xmp for starters,put vdroop to auto
