Hi Guys,

I was having a little issues with the most recent P95 27.7 AVX version and my Overclock, you can read all about it in this thread:

Z77A-GD65 + i5 2500K Overclocking - How to start?

Have you guys also had issues with this version of Prime? I was able to stabilize 4.6 GHZ with a 1.38 Vcore on IBT but P95 would constantly fail and give me a BSOD, I managed to do 4.6 on Vcore 1.43 but eventually I decided to lower the Vcore to 1.4 and settle for 4.5 which was completely stable.

Would love to hear what you guys think, thanks.

One did read the manual and followed that part of the manual to the letter (along with every thing else :). Connected mouse and keyboard to USB2 ports, and installed Windows off a USB drive on the front USB2 port. USB3 drivers were installed before connecting anything to the ports.

The UD5H has 3 USB controllers but only 2 out of the 3 seem to be working. There have been no devices connected to these ports before now and only two USB3 controllers are showing up in device manager.

Given the board is less than a week old I'm inclined to RMA it and grab a new one.

Bold added by me.

I believe you are supposed to have a device (i.e., mouse, etc.) connected to a USB 2.0 port before installing the USB 3.0 drivers. Try uninstalling the USB 3.0 drivers and then plug a mouse and/or keyboard into a USB 2 port, then install the usb 3.0 drivers.

Due to a Windows 7 limitation, please connect your USB device(s) to the USB 2.0/1.1 port(s) before the Intel USB 3.0 controller driver is installed.

I find the wording a bit vague.
Is one installed usb 2.0 device sufficient?
Should a usb device be installed in each separate pair of usb ports?

I sent an email to Gigabyte about this asking the same thing and got a reply that they are looking into it. See thew volley below...

[I]I visit lots of user forums that converse about this motherboard (Z77X-UD5H).

It seems the USB hardware on this board is always a topic of discussion. We have found not all USB ports are equally functional. According to the device type used it dictates if rather the case/wired ports, or if the on-board ports work best. Very frustrating.

One thing we would like an explanation on is a statement from the user manual.

“Due to a Windows 7 limitation, please connect your USB device(s) to the USB 2.0/1.1 port(s) before the Intel USB 3.0 controller driver is installed.” We would like Gigabyte support to elaborate more on this statement.

• Does it mean assemble the system and install Windows then the Chipset Drivers, then insert a USB 2.0 device and let Windows acknowledge it. Then install the USB 3.0 drivers? The (s) in USB device(s) makes us wonder if we have to already know of all the USB 2.0 devices we plan to use.
• Please explain the Windows 7 limitation mentioned or reason.

As you can see the statement in the manual is very vague and leaves so much open to interpretation.

We would also like to see the USB functionality work better at boot so wireless keyboards are recognized soon enough to use the “Delete” key so to enter BIOS. My GA-EP45-UD3P & GA-EP35-DS3R do great in this area. Why did the ZX77-UD3H lose this functionality? We love a fast board but it seems is skipping by this area.

*********** The Reply***********

We’re not awared of any known-issue with the motherboard, but we got to know that the latest Bios update for this board will actually improve certain type of keyboard compatibility and enhance chipset performance, please check and ensure that you’re using the latest Bios for this motherboard:
GIGABYTE - Motherboard - Socket 1155 - GA-Z77X-UD5H (rev. 1.0)

We’ll look into this statement: “Due to a Windows 7 limitation, please connect your USB device(s) to the USB 2.0/1.1 port(s) before the Intel USB 3.0 controller driver is installed.”

That is what I said I did. The section you highlighted in bold refers to the USB3 ports. I had the mouse and keyboard plugged into the rear USB2 ports the whole time (before, during and after installing the drivers). I only started plugging other peripherals into the USB3 ports.

I find it strange that 2 of the USB3 controllers work but one doesn't. Based on the motherboard layout and block diagram onpages 7 and 8 of the user manual I'm assuming the following (I could be wrong but I've assumed the VL810 chips are located near the ports they service rather than being too far away):

• Intel Z77 Chipset runs F_USB30_1, F_USB1, F_USB2 and the rear USB2 ports (all working fine)
• Front VIA VL810 Chip runs F_USB30_2 and F_USB30_3 ports (powered but no devices will connect)
• Rear VIA VL810 Chip runs rear USB3 ports (all working fine)

If it were I driver issue I would expect to have both VIA VL810 chips not working, rather than one working an one not working. I've RMA'd the board and pickup up a new one today anyway so will try the drivers if this one doesn't work (I know that's taking the easy way out).

Replaced the motherboard and now my problem with the internal USB3.0 headers is resolved. Didn't need to reinstall windows or mess around with any drivers.

Updated first post with Bios screen shoots and added a couple bios to the list

[Acebmxer]

Max overclock so far...




CPU-Z Validator 3.1

[profJim]

I'm impressed!!
How are the cpu core temperatures? at idle? while stress testing?
Stability?

[Acebmxer]

only stability was cpu-z validation. I can get 5.2 stable with w/prime but temps hit 105 on core2 when using 4 theads.
