OCCT and 4790k questions

Okay, so I have read both of these articles/reviews:

http://www.overclock3d.net/reviews/cpu_mainboard/gigabyte_z77_overclocking_guide/1


http://www.overclock3d.net/articles/cpu_mainboard/how_to_manually_set_and_undervolt_your_cpu_vcore/1

Now specs:

CPU: Intel i7 4790k
MB: MSI Z87-GD65 gaming
PSU: XFX PRO 750 W Black Edition

So. I manually set the voltage to 1.100 V (MB reads 1.112 V).
Core Multiplier x44.
Mode being OVERRIDE, of course.
VDROOP offset set to 100%

In the article the voltage was set to 1.13 V and OCCT correctly displayed that as 1.13 V with VDROOP set to extreme.

Mine is displaying under 1 V.

Here are some screen shots:



Core Temp seems to be the only one "correctly" displaying the Core Voltage i set.





Any idea why the CPU VCORE is not displaying 1.100V or something close to it in OCCT?

Thanks guys

=========================== EDIT for Update ==================================

I was able to get 4.5 GHz stable at 1.140 V. However, I'm still getting similar readouts from these programs:

OCCT: 0.905 V
CPUZ: 1.160 V
Core Temp: 1.1412 V

Still confused about why the voltage in OCCT is displaying so low. Thanks again

=========================== EDIT for Update 2 =================================

Unless anyone states otherwise, I'm going to chalk up the difference between CPUZ and Core Temp (0.02 V) as normal, and that OCCT is not optimized for the 4790k. I'll check for updates and get back to myself haha

hey! I'm kind of having similar issues. Like OCCT displaying 1,5 in vcore when both AIDA64, HWmonitor and cpu-z is displaying the value 1,188(which is the one i set in bios)
anyway, since the base voltage without overclock is set to 0,86v in OCCT this might be displaying incorrectly. (just a theory) i know that my 4690K can run base speeds at 0,713v. i think you can easily chalk up the 0,02v difference as normal, i also experienced that with other programs depending on load etc.
im not sure if the fact you also are running a haswell refresh with a z87 series mb makes a difference as well.
sorry im not much more help with this
btw, how did you edit your signature?

Hey puck I was talking with JJ from Asus a few weeks ago about stability tests on the Haswell platform and he mentioned that programs such as Prime95 and OCCT aren't really the best to use with the Haswell chips as they have seen some very odd results.

AIDA64 is the best stability test for Haswell according to JJ from Asus as it was written with Haswell in mind were as the 2 previous programs I mentioned were not.

Again I am not pulling this from thin air but an actual conversation I had with JJ from Asus i.e the people who work with Intel.

Thanks for the response! It may be like Dicehunter said. The programs just aren't the best for Haswell. As far as a signature edits go, it will be available to you when one of the mods get to your account. Same with a picture. Welcome to the forums!

Okay thanks! I was concerned for a bit! Now I'm having GPU issues haha my life

Well the programs are good just not written for Haswell, Again incase I get told off for this I got the info straight from a very reputable and well known Asus employee.

I believe you

Are you overclocking with a manual or adaptive voltage? That makes a huge difference to which test might be dangerous or not.

Personally I can't see the point of an adaptive voltage when the fiVR will automatically drop the voltage off load anyway. Many programs, like Prime, will not react well to the adaptive voltage table and can dangerously over volt your CPU.

This is override voltage. At least, that's what my option is in the BIOS. Override, Adaptive or Auto are my options. I went with Override
