msi z77a-g43/i5 3570k overclocking issues

southernorth · 19 Dec 2016 at 02:26

I'm using an msi z77a-g43 with an i5 3570k, which is running at 4.2ghz @ 1.33v.

The voltage seems a bit high, but not dangerously high. I want to lower this voltage but I don't seem able to in my bios. I can only put it to auto voltage, or increase it in small increments (not decrease).

I have attached some images below of my bios overclocking screen.

Thanks in advance for any helpful suggestions

Try cpu-z for your voltage reading.

Thanks, now 1.304 - 1.1312 is being reported.

Maybe I'm just looking into a non-issue but I've read that running CPU's at 1.3v or above isn't good longevity wise?

4.2ghz overclcok should run at about 1.25 to 1.275 v core, you could check to see if you got the latest bios for your motherboard that may nelp.

Yep, is on newest version.

In the second picture I posted there is "CPU Core Voltage [+ 0.020000]"

When I click this there is no option to reduce voltage, only go up in small increments.

Just found on the web that the motherboard you have has limited adjustment for voltage options and only can be adjusted slightly with the cpu core voltage.

Basically the motherboard is auto adjusting the voltage to your overclcok which is slightly higher than you would like.
