Title: Gigabyte Z77M D3H - CPU Voltage Adjustments?
Post by: Yamcha on May 08, 2012, 06:01:13 pm

Hello,

Just bought this motherboard a while back and everything seems to be working perfectly however I see that there is no CPU Voltage adjustment.. Now is there a way to enable this? Or am I stuck without this feature?

Hope someone can shed some light on this..

Thanks

According to manual in Advanced Voltage Setting you can adjust only DRAM Voltage.

Thanks for reply, It's as I expected but I was hoping there was a hidden menu.. Anyways I really hope we see voltage adjustment in entry level Gigabyte boards in the future..

I'm having the same issue with the DS3H.

It really doesn't make much sense that you can set the CPU VTT ,PLL and DRAM, but not the Vcore.

I must say that I am a little surprised at this myself and expected it to be an available feature on all boards. Maybe it is something that could be enabled in a BIOS upgrade. ex58 is the one to answer that though.

BIOS upgrade won't help.
It is the hardware limitation (GIGABYTE All Digital Power Engine).

Must have at least Z77-D3H , to change Vcore.

Thanks for the explanation ex58 at least we all understand now why the limitation is there on this board.

Dark Mantis and ex58. I know that Z77M D3H has Auto Vcore adjustments. Do you what is the maximum voltage that it can deliver to the CPU on auto? I have mine at 1.164V running a 4.3Ghz 3770K. If I increase the frequency to 4.4Ghz, it won't increase the voltage and it crashes. Is it the maximum already?
