haswell overclock voltage question

username455 · April 17, 2014

Hello everyone

I am working on overclocking a 4770k (4.1 is as high as it likes to go) but I am bothered by my voltages. They are always higher than what I input in the BIOS (asus maximus vi hero).

I have voltage set to manual, input 1.25, and get readings of 1.265 up to 1.28. I have triple checked I am not on adaptive mode but it still rises above what I set for a manual vcore. I have left everything else on auto for the time being.. am I missing a setting somewhere? I have also reset to defaults twice now, re-entered my voltages, and same result.

I use realtemp, cpuz, HWmonitor, prime95, and Intel ETU for testing

I'm not sure but I think prime95 uses more than specified

Well even on the desktop it reads higher voltage than my settings.

Also, for whatever reason my voltage is fluctuating now. For testing I try to turn off all power saving options to keep a constant voltage. I dont know what setting is enabled somewhere causing voltage to drop down to 0.2. That sounds a lot like adaptive mode, but again, I am using manual. kind of frustrating

I think I got the exact same problem. You're getting BSOD's from this right?

Haswell sensors may be a little off sometimes. Its hard to say what your true voltage is, unless you can measure with a multimeter. shame on asus for not including vcheckpoints on a board priced over $200.00

I would rely on what the asus AI software tells you your cpu voltage is.

Does your Voltage still increase if you stress test with XTU? make sure to confirm in XTU your voltage mode is set for static

under load it is normal to be out +\- .002V when in static mode.

Heres what cpuz, xtu and msi software say my vcore is at! which one is accurate? The MSI voltage reading is most accurate (hardware monitor). I have confirmed this with a multimeter thats why I say your best bet is to monitor your core voltage with AI suite.
