Hello

I installed a new Gigabyte Z97X-Gaming 7 motherboard today with a i7 4770K CPU that I had set aside spare from another member that I procured a while back.

When installing the kit I noticed that my H100i tubing caps had perished massively so I swapped it out for a H100 that I had spare.

In the process this made a small scratch in the board just south of the CPU socket.



Since then I have noticed that the UEFI, BIOS and System Information Viewer have been reporting that the CPU has been running at higher and higher voltage that keeps increasing.

In Gigabytes system Information Viewer it says that the CPU is sitting at 2.172V.

which seems crazy high to me but the CPU and PCH are reporting around 25-35 degree range.

The system has been locking up when I run CPUZ as well.

No matter what I do in the bios to tell it to not run above 1.28v for the VCORE it seems to continue to with these voltages.


I'm hella confused and a bit worried, but correct me if Im wrong. But would the CPU not be showing stupid heat levels or very unstable unable to boot to windows if it was really 2v+?

Any advice is welcome :(:(:(
 
F4 which is the latest, the scratch on the board does expose the copper channels but it hasn't broken them and they aren't touching each other...

The voltage is now sitting at 2.208v, I cant think this is reporting correctly, would have thought the CPU would be fried by now.

Whats the best way of doing this Stulid?

It seems to staying about 2.16-2.204v's under load at about 4.3Ghz, temps are about 40-45 with the odd push to about 55 when really loading the CPU.

Does these volts make sense to you, also is it possible that its a voltage leak from those lines I have exposed due to the scratch?

Also I failed to note that I had to take my Corsair Obsidian 800D Sata hotswap bay array back plate off and directly hook up the drives to the sata ports on the motherboard.

It would not see my boot SSD on any channel while my SATA3 and SATA2 array PCB was plugged in between the cable and the hard drive.
 
try latest bios first,download/extract it to a usb stick,reboot into bios and press f8 or end and point qflash to the bios file on the stick

then see what the temps are,you can always seal the scratch with some clear nail varnish,it might pickup the hdd's aswell,if not try enabling hotswap for each sata port in the bios
 
I have upgraded the bios via a reboot and no luck with the voltage, this morning in the bios it started at 0.7v and now in windows the gigabyte software is reporting 1.344v as I type this.

Can the scratch be causing this, when I did the bios last night the voltage went straight back to 2.2v.
 
I have heard of people killing haswell with 1.5v through them. Using 2.2v in reality your temps would be going nuts, possible shutdowns and most importantly would the system even work ?

I am thinking more along lines, faulty temps reports/monitoring. Possibly caused by the scratch you mention ?

Download hwmonitor and see what that states ?
 
Can you download the latest CPU-Z.

Install and run it and look at the main CPU tab.

What does the Vcore read when idle for a few minutes and when you stress the system with something like a Cinebench run.
 
I have updated CPUZ to the latest version and it shows the Core Voltage hovering at 0.717v spiking at times as its doing some processing of outlook mail just now. Gigabytes System information viewer is showing 1.848v at the same time constaint.

Could the scratch on the keyboard becausing the software to be reading this wrong?

Once outlooks done I will run a Cinebench run.
 
It depends what V the gigabyte software is reading, early CPU-Z use to read the Vid and not the true Vcore and thats the only program I have ever used.

With CPU-Z running and visible, run cinebench which will load your CPU and the vcore reported should jump up to its true maximum value.
 
Hello Stulid

the VCore in CPUZ goes as high as 1.081v when doing a CPU run in Cinebench R15 (Run 4 times). The CPU also pushes to about 60 degrees on the temps monitor in gigabytes software, the voltage of the CPU in the software as well just keeps increasing. Its at 2.016v according to the System Information Viewer.

I'm wondering where each program is taking a reading from...

I'd be more inclined to trust CPU-Z.

Let me just install the giga software and see what it says vs CPU-Z.
 
I get this (but with a 4970K,

Are you sure the value you are seeing is not Vrin?
 
Where your CPU entrie is in the Gigabyte software mine reads 2.136v and CPU-Z is showing around 0.717v.

My CPU VRIn is at 1.72v

Could this be the scratch?
 
I have no idea if the boards been damaged.

But if it was getting 2.136 I would expect higher temps than 60C and maybe even a non working CPU.

What do other programs such as HWmonitor say?
