Gigabyte GA-Z77X-UP7

Introduction
Product Page Gigabyte GA-Z77X-UP7

My Opinions
In my opinion, after experiencing the ASUS P8V77-V motherboard with the bad Realtek ALC 892 chip when recording line/mic, hibernate issues with add-in video cards likely due to legacy PCI, technical support contact issues; this Gigabyte GA-Z77X-UP7 board was an extreme pleasure working with. I did find the BIOS somewhat trivial to navigate, but it's similar to all motherboard BIOS these days.

Bought this hardware several months ago and has been rock solid ever since. Not one issue. A good example of, you get what you pay for! And at this cost, it better! ;-)

This motherboard does include an onboard serial DB9 port, incase there is ever a LinuxBIOS/Coreboot attempt.

From my past experience, I would just install the maximum amount of RAM now, rather than waiting; as the prices may likely increase or the type of RAM may not be as readily available. RAM prices are not like they were a decade or more ago! (ie. Corsair Vengeance 32 GB DDR3 1600MHz CMZ32GX3M4X1600C10) Expect Windows 7/8 to only use 4-8G of RAM. Almost all applications/games currently expect to use no more than 4G. However, you'll notice Linux will gladly buffer whatever you have!

A good quality cheap basic case is the Cooler Master HAF 922 (RC-922M-KKN3-GP). (Switch for turning-off the eye candy red lights.)

If you're an audiophile or Blu-ray Movie buff, you might want to pipe your audio through an external DAC (ie. Yamaha RX-V375) via HDMI. Lots more options are stated below.

Performance
Compiling the kernel takes mere minutes to no more than a minute using MAKEOPTS -j8. Compiling world, or all your needed applications and packages for your Gentoo O/S, takes only a few hours -- or maybe an hour. I'm not sure, and have no desire to time the exact amount of time as I'm used to compiling world on an x86 requiring 24-48 hours.

Linux Compatibility
To the best of my knowledge, everything works.


 * 1) USB-3 Ports work, but I have no USB-3 hardware for benchmarking to verify USB-3 speeds. I assume they are.
 * 2) I have no Bluetooth hardware, but Fedora states Bluetooth is working.  No warnings or issues.

Integrated Motherboard Chips
These are some chip details, which are omitted within the sales brochure and vendor documentation. You'll need to know this if you're looking for drivers, or comparing chips (ie. Intel SATA vs Marell SATA specs) for optimizing your setup for best performance.

Realtek ALC898
The audio and microphone is of good quality with no static or low volume issue during playback or while recording. Comparing to a ASUS Xonar Essence STX PCIx card, the Xonar displays a, to be expected, better frequency range of sound. If you're an audiophile or demand quality mic recording, then as usual, consider the ASUS Xonar Essence STX PCIx add-in card upgrade. However, I am very impressed with the quality and find the ALC898 very good for everyday use by most normal users. (Used several months, but migrated to a ASUS Xonar Essence STX PCIx card.)

I have heard one report, SPDIF/Toslink port provided by these many onboard audio chips, can only transport uncompressed two channel stereo audio and not compressed Dolby/DTS, as the SPDIF protocol specifies compressed Dolby/DTS should be possible. During extensive research of the forums looking for quality reports, I've heard the onboard SPDIF/Toslink is slightly not as good as a dedicated high quality sound card. (Although, this is for those finicky with audio quality!)

Atheros 8161-BL-3A or AR8161 Ethernet Controller
The Atheros chip looks like it has less pins and surface area then the Intel chip. Use alx driver from compat-wireless. (Disabled within my BIOS settings as I use the below Intel Ethernet port, with no need for a second port.)

Intel 82579V Ethernet Controller
Likely use this, #2 port, as the primary Ethernet port as it likely will perform better than the above Atheros Ethernet chip. Uses the e1000e in kernel driver.

VIA VL-800-Q8 USB 3.0 Host Controller
Rear case ports.

Etron EJ168 USB 3.0 Host Controller
Internal case ports, for wiring to front case ports.

ASMEDIA 1442 x 2 HDMI Chips
HDMI Ports. Likely you can utilize these to pipe audio to an external DAC or Receiver. (ie. Yamaha RX-V375). Using the HDMI port for better audio quality than onboard, will allow you to pass through uncompressed audio for Blu-ray and Dolby/DTS movies. SPDIF/Toslink can only transport either uncompressed two channel stereo audio or compressed Dolby/DTS and not Blu-ray quality audio. It is preferred to utilize the HDMI ports for DVD Dolby/DTS or Blu-ray audio. Most music still uses stereo, and an add-in sound card with SPDIF/Toslink might take some load-off the bus for other CPU demanding tasks, while simply passing through digital audio to the receiver with maybe better quality then the onboard optical or HDMI ports. Lots of choices here!

Marvell 88SE9172(-NNX2?) x 2 Storage Controller Chips
Use this controller for the Windows XP hard drive. Trying to install Windows XP on the Intel Storage Controller will result in blue screens and other instability issues! (Windows 7/8 can go on the Intel Storage Controller.)

Add-in 802.11 & Bluetooth PCIx card
Atheros AR5B22 (or ARB522, see AR9462 for specs?) mini-half-sized card with 802.11 & Bluetooth (04ca 3006), with bluetooth being attached to internal USB port.

Optional Aftermarket Accessories
The parts below are not purchased with the Gigabyte GA-Z77X-UP7 mainboard. The Intel i7 i7-3770K CPU, as of this writing, is probably the CPU you will likely buy for this board, unless a newer faster one is available. The ASUS Xonar Essence STX and EVGA NVidia GTX 670 2G RAM are completely optional, and for most users, not needed at all as I think the onboard RealTek ALC898 sound and the onboard Intel i7 i7-3770K CPU graphics (called iGPU) are completely adequate. Only reason why you would want to upgrade, you want to reserve more CPU for other tasks or are an audiophile. (The information provided below is to advise you these pieces of popular hardware work well with this mainboard.)

Intel i7 i7-3770K CPU
This specific Intel CPU provides some accelerated Virtualization features (ie. VirtualBox) along with adequate onboard graphics output commonly referred to as iGPU. Open Source drivers for iGPU are within the Linux Kernel, including source code for accelleration for media players. (ie. MPlayer) (As of this writing, it's still the best bang for the buck.)

This BX80637I73770K or boxed version, does include an adequate fan. I didn't initially realize this and based on past experiences, I just bought a Cooler Master Hyper 212 Plus CPU Cooler (RR-B10-212P-G1). I'm not sure if I wasted my money on the fan, as the included generice seems similar.

ASUS Xonar Essence STX
The ASUS Xonar Essence STX PCIx card, a competitor motherboard manufacture, works fine on this Gigabyte motherboard. Apart from the other ASUS hardware, this card's quality is phenomenal. If you're an audiophile, well worth the money for the Brown-Burr SNR 128db DAC, still far superior from todays receivers. Even so, still provides SPDIF/Toslink for digital audio pass through, likely off-loading some of the audio digitization from the onboard parts to a soundcard dedicated to audio quality.

NVidia GTX 670 2G RAM
A EVGA NVidia GeForce GTX670 FTW 2048MB GDDR5 PCIx card works fine, even when using NVidia's binary drivers -- including full bug-free hibernate and suspend support, so far. The basic Linux Kernel Nouveau video driver, without 3D accelleration, works as expected.

Testing Your Hardware
In the meantime while waiting for me to publish all the chips with driver names (ie. Linux Config file), users can easily use a recent Fedora LiveCD which should certainly display and test that all your hardware is certainly working! I haven't tested with the latest Gentoo LiveCD, as the latest version wasn't released until after I had put my board together. Readers can follow-up here and note if the Gentoo LiveCD displays working wireless and bluetooth drivers. Most everything else should just work.

Compile in Memory
The following tip, if you've installed a large amount of memory such as the full 32G, will specify Portage to compile all packages within memory instead of using a hard disk filesystem. The speed-up is phenomenal, but I'm finding on these 64bit platforms, it might not be as fast as you would think due to bottlenecks and collisions. Some packages also may have bugs with this feature and will fail during compile. Probably not a good idea during your initial "emerge world". (If you do use this, and find a package fails, remember to submit a bug to Gentoo Bugs.)

Check Microphone/Line-in Quality
Check using Gentoo's Wiki "ALSA - Test Mic Recording".

Bugs

 * 1) [Not a Bug, but frequently over looked.]  This motherboard includes a wireless WI-FI and Bluetooth Combo add-in PCIx card.  The PCIx bus handles the WI-FI feature, while users need to plug the Bluetooth into an onboard internal USB port with the included USB cable.  Without the USB cable attached, users may experience no BlueTooth within Linux, while Window's users will not be able to install the Atheros drivers due to the driver package failing to find both, the Wireless and Bluetooth devices.  From memory, this device only works within Windows 7/8 and not Windows XP due to Atheros not publishing drivers for 32 bit platforms.  (Going from memory as to the reason for lacking Windows XP support.)
 * 2) [Only for MS Windows' users.]  In order to be able to use the USB-3 ports within Windows 7/8, users need to download the Intel USB3 drivers directly from Intel's website as the Gigabyte drivers for this motherboard omit them.  (This appears to be a licensing issue.)  Intel does not provide 32 bit, or Windows XP USB-3 drivers.  This issue is irrelevant for Linux only users, as USB-3 should work fine as they're included within the Linux Kernel.
