CPU Z reads different from ASRock UEFI

post #1 of 13
Thread Starter 
Hello guys,

just wondering if somebody ever had this problem before, just tried to OC my current setup using offset and stress with P95 for 20minutes without any error but the reading (values) of my i7 3820 manually set on the UEFI are different from that of CPU Z? can anyone enlighten me on this issue? below are the screen shots of my setup.

your help is highly appreciated.

thanks



UEFI multiplier set at 44






Core speed at 4620 MHz with UEFI version L2.14 (Beta version from ASRock website)


CPU Z is indicating multiplier of 43 and core speed of 4514 MHz


P95 completed for 20 minutes without error.

Hi

CPUZ is indeed displaying a different voltage value (slightly up) than the one I have in BIOS.

But the multiplier and speed values are the same in BIOS and in CPUZ.
Did you hit F10 before leaving the BIOS? upsidedwnsmiley.gif

It's a known fact, that the Asrock boards using more voltage than CPU-Z shows look at this thread
http://www.overclock.net/t/1349216/is-asrock-really-cheating-us-on-software-voltage-readings

Got the same with my Extreme 6 best you can do is to use level 4 Loadline calibration this setting have the less difference in voltage

hi thanks for the quick reply, actually its the difference of the core clock speed and the multiplier that were preset on the UEFI and the reading displayed on CPU Z that puzzled me, really got no idea on how to go around this. For the voltage value, I would say that its acceptable for me.

hi, thanks for the reply, don't you think that the voltage of 1.344V for 4.5+Ghz core speed on CPU Z is acceptable? TBH i'm quite happy with this voltage with no error with P95 stress for 20 minutes compared to my previuos set up that reaches 1.395V at 4.6Ghz core speed.

Anyway i will try LLC at level 4.

many thanks for your reply

sorry, i don't get what you mean? Afterburner for CPU overclocking? I've got no problem with my GTX560Ti DC2 in SLI with 1050Hmz core speed. can you please tell me where to find the option to disable power play in afterburner? rolleyes.gif

Looks like you got a voltage hungry chip there :-) i need only 1.328 v to get 4.8 stable but you are on a save voltage

have you tried disabling the ez oc settings? You are setting everything manually, there is no need for the ez setting to be on auto. Not an expert opinion, just a guess, and a simple one to check.
