Hi,

I have a question about overclocking with the GA-X79-UD3 using F10 (or F11b, F11c) BIOS.
I am using an i7 3820 CPU (my full pc specs are in the blue link top-left corner of this post).

Overclocking using the 1.00x strap is a breeze and the board is rock solid stable.
I am using SVID (vcore set to normal in BIOS) with a DVID offset of 0.00v.

With this method the SVID value increases properly as I increase the CPU multiplier and reboot.
Doing it this way lets the board idle at 1200MHz with a vcore of only 1.0v or so, and the vcore increases
to 1.265v when the CPU is running at 4.3GHz as it should. Both the BIOS and Easytune 6 show power-on vcore
to be 1.24v and I have no problem cold-booting.

When I use the 1.25x strap however I have a problem. Power-on vcore stays at 1.00v regardless of how high or low the cpu
multiplier is set and how many times I reboot. I think this is preventing me from booting the system past about 2.5GHz - 3GHz. If I set vcore
manually to 1.265-1.275v I can boot at 4.5GHz no problem. But now the vcore will stay at 1.265-1.275v even when the CPU is idle
as SVID is no longer active.

Is there a way around this problem? Or can we get a fix for the power-on vcore in the next BIOS please? When using higher
straps I don't think the power-on vcore is supposed to be 1.0v. It would be great to be able to use SVID (+DVID if needed) when using
1.25x strap so that the CPU can idle at low voltage but still achieve a good overclock (4.5GHz or higher).

Apart from this one issue I just want to say this is a great board and well priced too!


Thanks.

Belkin KVM won't work with Gigabyte motherboard

This is a rather strange one.
You would think that connecting a KVM to a USB port on the computer would just be a straight forward 'plug-and-play situation.
Apparently not.
I bought a BELKIN SOHO KVM to switch between 4 USB computers: 3 Macs and a PC. The unit works perfectly with the Macs but not the PC.
I'm running Win XP SP3 with the Gigabyte motherboard listed below.
The Kbd and Mouse are Gigabyte USB type.
The motherboard is GA-H61MA-D2V.
When switched to the PC, the Mouse and Kbd don't work and the LED flashes on the SOHO switch - indicating there is a problem.
'Found New Hardware' comes up on the PC and in Device Manager it says it is looking for the driver: Combo Free KVM.
I'm not aware of any driver of this type and anyway the BELKIN unit should work without software.
The odd thing is that the Kbd and Mouse work OK in BIOS and the LED on the KVM is full on, but when the computer boots into Windows - they don't work.

Can anyone help?
Any clues please.
Belkin technical help seem to be useless.

Hi I believe you still need the windows xp to recognize the device and install a driver. In most cases this is automatic. Did you try the auto update on Belkins technical web site? You may want to try to enter your Belkin SoHo KVM model number at the following web site. I believe you would need to be on the xp computer while performing this. Unsure of your model for more research, but it's worth a try.

Thanks for the suggestion,
Tried it. Didn't work.

Is there anything in the BIOS that needs to be enabled?

The motherboard obviously sees the KVM because the mouse and keyboard work during BIOS setup, but when the computer boots into Windows it's asking for a driver:
Combo Free KVM

Is there such a driver somewhere I can download?

Belkin are absolutely useless - nothing on their site. They just keep saying it doesn't need a driver.

Any clues? Anyone ?

Do you have installed latest Etron USB drivers,I think is Etron USB 3.0 driver v.112.
And try with latest F4 BIOS.

Anyway,I doubt you can do this in XP.

Hi,

I received yesterday the GA-Z77X-UD3H and set it up to test (outside of case).

It will boot up ok initially and I will get a brief view of the Gigabyte splash screen and then the screen will go blank. It does not matter which connection I use this always happens. Everything is still running but the screen is blank. I have used both onboard outputs and the graphics card output but to no avail.

I have tried without the graphics card plugged in but the same thing happens.

The USB keyboard and mouse are lit up and all fans are going but no display after the brief view of the splash screen. Is the motherboard faulty? Or am I just missing something?!

Thank you in advance.

Try to clear CMOS (unplug PSU) and update BIOS.

Thanks Stasio,

Not sure how I can update the Bios when the screen just goes blank. I have tried pressing End during post. It gets to splash screen, I press End and I get a flashing cursor in top left for about 1 sec and then the screen goes blank again.

I have cleared the CMOS to no avail.

I am no expert by any means but I am certain I have everything set up right (I have kept it very simple just to try and get it to display properly.)

Try keyboard with PS/2 or other USB port.
Any other keyboard?
You must went in BIOS first to arrange first boot from drive IDE/AHCI.

Never got into Bios at all. This has been happening from first power up.

The keyboard is definitely working. On a couple of occasions I have seen the screen (very briefly) where there are 2 options available (load defaults and reboot). This screen only flashes up after resetting CMOS and then I have to remove and replace the VGA cable to see it briefly. However when it disappeared I pressed down on the cursor on the keyboard, took out the VGA and replaced, screen flashed up again and the highlighted option had moved down one. When I pressed enter the system rebooted.


Splash screen then comes up again and then disappears. I only ever get any screen up for less than a second.

Looking at the codes that come up as it start up it goes through a different numbers. Get to 99 (super IO initialization), then A3 (Acitivated all currently connected IDE devices; that is when splash screen comes up), quickly jumps to A9 (BIOS setup started; splash screen disappears & everything goes blank) and then settles on A6 (Detect and install all currently connected SCSI devices).


Also when I have cleared the CMOS and reboot it switches itself on and off 3 times before powering up properly.



My concern is I received this motherboard yesterday and it looked like the static bag had already been opened and resealed. I guess I might have to send it back. Spoke with customer services who will refund it on return. I might just order a new one today for delivery tomorrow. I hate giving up on a problem though!
