BIOS

The SuperO BIOS starts off with an EZ Mode which displays pertinent information about the current system state. Across the top gives date/time as well motherboard and BIOS version as well as information about the CPU (clock speed, BCLK, VCore) and Memory (capacity, frequency, voltage), and includes temperature readings for the CPU and chipset. 

Users are able to change the boot order and HDD list on the right side. As a side note about booting - the board arrives by default setup for legacy BIOS and I was unable to get the drive within the boot order until it was switched to UEFI. Outside of that, we are also able to load CPU profiles, enable/disable XMP profiles, as well as enable/disable Fast Boot from the EZ Mode Screen. One thing that does look out of place however is the text clipping between the motherboard name and some of the information.

Once in the Advanced Mode, the bottom 2/3 of the screen changes with a menu on the left side and display areas to the right. There are a total of six sections - CPU, Memory, Advanced, Thermal & Fan, Save & Exit, and BIOS Update. The BIOS is a new design from SuperO compared to past offerings. While most items are located in logical places, if you have never used a consumer level SuperO board, it may take a bit of getting used to. 

The CPU section is information on the first page with three options to dig down. The CPU Overclocking section (two smaller images below) contains most of the options needed for overclocking including CPU Ratio, BCLK, Voltages, and power limits among other items (no current limit settings, more on this in the overclocking section). The CPU configuration section is where we can enable/disable CPU specific features such as Hyperthreading or VT-d for example. 

 

The Memory section holds the keys to editing anything memory related. Users are able to enable XMP profiles, change memory frequency, timings, and voltage within this section. The board offers a lot of primary, secondary, and tertiary timings that can all be edited. There still needs to be tweaking with this design however, as shown with the inability to line up values in the list below.

 

The Advanced section contains multiple sub-headings where system features are able to be accessed and edited. Items such as Boot Features, Graphics Configuration, SATA and RST Configuration, and USB configuration among several others. 

 

The Thermal & Fan section displays system temperatures as well as voltages from the power supply as well as internally on the motherboard. Inside this section, users are able to configure fan speeds for each header. There are standard profiles as well as the ability to customize each. 

The Save and Exit section contains boot mode selections (Legacy and Dual) as well as boot order priorities. In order to get the board to recognize my standard SSD in the boot order, I needed to change it to 'Dual' upon first boot. Though oddly enough, once I selected dual and set back to optimized defaults, the drive was still there even though it was in Legacy mode again. 

Last but not least is the BIOS Update page. When selecting the Start Update function on this screen we are prompted to go to the SuperO website to download it, or not. If you click No, it will then open up a dialog box looking for the BIOS file. In previous generations it has been a struggle to update the BIOS on these sorts of boards, however we are glad to now have the option.

Overall, the BIOS worked out pretty well. As mentioned earlier, if you are not used to these BIOSes from SuperO, it may take some getting used to, however, almost all functions are there. I would like to have seen current limit settings as well as an LLC option so as to bypass the strict power limits (see overclocking section) and stabilize voltage under load. 

Software

The SuperO C7Z30-CG-IW's driver disk offers a basic list of drivers and software used to set up the system properly. Simply click on any of the buttons and the software will install, however there is not an 'install all in one shot' option (with the ability to deselect items not needed) as with the primary motherboard manufacturers. The latest drivers will need to be downloaded from the website as this disk as there is no live update tool.

The SuperOBooster software is SuperO's Windows-based utility for monitoring and overclocking/tweaking the system, updating the BIOS, as well as controlling the RGB LED lighting on/attached to the board. It also has profiles for overclocking with an OC Mode and an Auto Tuning function said to find the best overclock for the board. 

The Luminous section below is used for manipulating the RGB LEDs on board. It has a total of six different profiles users are able to select plus an off function to set these up just the way the user likes. 

For Audio, SuperO uses the premium ALC1220 codec and does not use additional software on top. Below is the Realtek HD Audio Manager software used to adjust any audio feature from pre-defined room acoustics to custom equalization. Your audio options will all be found here.

    Hi Joe, How is the Realtek Wifi card compared to Intel? And How many onboard USB Headers are available? and which versions are available, I see you mentioned USB 3.0 but are there others? Thank you... Reply
  • Srikzquest - Monday, April 30, 2018 - link

    Sorry, read it again and I see there are 2 USB 3.0 and 2 USB 2.0 onboard headers available. I still would like to know more about the Realtek Wifi Card though, I haven't see any itx boards with that so far. Reply

    On page 4 of the review under "Board Features" the card is listed as:
    1 x Realtek TRL9922BE Wi-Fi ac 2T/2R

    I don't have any direct experience with this model, but I have used their previous generation RTL-8821AE which is a 1T1R wireless-AC card. It came with a mini-ITX H97 board I bought for home theater use.

    For Wi-Fi only duties the card performs fine, but the link rate is limited to 433Mbps due to the single stream nature of the card. With good signal I got almost exactly half the sustained transfer rates as with a 2 stream Intel 7260 or with the 2 stream Broadcom BCM94352. So in that regard performance seemed to be pretty good, matching what was expected based on the specs.

    That said, I definitely saw some strange behavior when I tried to use Wi-Fi and Bluetooth simultaneously (playing audio to a BT speaker while watching streaming video online). Either the audio would have frequent dropouts OR the data stream would be interrupted, causing buffering.

    My guess would be that, despite having both 2.4GHz and 5GHz capability, they only had 1 full transmit/receive chain and that the radio was having to cycle back and forth between the two to maintain both the wireless AC and Bluetooth. I worked around it by using a USB Bluetooth dongle I had on-hand until I was able to replace the card.

    Hopefully Realtek has addressed this with the newer model.

    There is interference between USB 3.0 and 2.4ghz wifi. As far as I know there is no solution other than moving the 2 as far apart as possible. Intel has a page about it here https://www.intel.com/content/www/us/en/io/univers... Reply

    Thanks, but:
    1. I was using 5GHz WiFi
    2. The card is mini-PCI-E, not USB.

    Yeah, the Bluetooth is probably connected over USB, but I've tested both the Intel 7260AC and Broadcom BCM94352, and neither of those has issues streaming video while also doing Bluetooth audio.

    I did further reading and looks like this particular card has MU-MIMO capability, may be that will help with the transmit/receive pipeline. Reply

    Anything stopping us from pulling out the Realtek Wifi card and putting in a card with the same interface, i.e. mPCIe Intel 8260, or a M.2 2230 9260NGW? Reply

    As limited as this boards power distribution appears to be I'm not convinced lifting the current limits is a good idea. Reply
  • Roen - Monday, April 30, 2018 - link

    The power distribution is better than the Asus, even though it has less phases, it can handle more juice. Reply
  • Srikzquest - Monday, April 30, 2018 - link

    It has all the features compared to other flagship boards except for Thunderbolt port I believe which if I am correct not many people use or need but other boards also do have their share of omissions.

    1. Asus ROG Strix Z370 I (No HDMI 2.0, No rear USB 3.1 ports, only Header available)
    2. Asrock Fatality Z370 I (No USB 3.1 Ports)
    3. Gigabyte Z370N Wifi (No USB 3.1 Ports)
    4. MSI Z370I GAMING PRO CARBON AC (No HDMI 2.0)
