Z87-G45 - CPU Core Voltage plus 0.030 V
Z87-G45 - CPU Core Voltage plus 0.030 V
Hi all,
today I tried to overclock my Intel i7 4770K. I achieved 4.2GHz by adjusting the CPU Core Voltage to 1.270V. But CPU-Z and HWMonitor are displaying 1.300V instead. I looked into some settings and noticed they often show 0.030V more than the value saved in the UEFI of my MSI Z87-G45. For instance, setting the core voltage to 1.250V would result in 1.280V according to those programs. Can anyone clarify this?
Rather than using a fixed voltage that works across all frequencies, I opted for a voltage offset. I adjusted a minor offset to turn off the automatic voltage from the motherboard, allowing my 3570K to run at 4.1GHz with the standard voltage.
It's pretty common for BIOS and software to read different vcore. It's also no guarantee that the mobo is right unless you measure with a multimeter. Either way, not a big deal if it's only .03V difference. Enjoy

The thing is that even the BIOS shows +0.032V (1.312V) even though I set it to 1.280V. Why is this? This can't be normal.

got the same Motherboard like me, sets his Core Voltage to 1.140 and just got a slight difference of +0.001V in CPU-Z under load (1.141).
Here's a picture of my BIOS:

once you get your CPU stable you will have fun with it for years, my 4770k currently stable at 4,2 GHZ with 1,175 vcore (69° in Prime95), i only OC for WoW. at this point there is no AMD CPU that might bring me a big difference in WoW and the 9600k which is the best option for WoW gamers is not a great deal atm.
