ASRock Z77 Extreme4 – BIOS

The ASRock graphical BIOS has evolved from the initial days of Sandy Bridge into a bright blue screen with options we see below.  With a graphical BIOS, there are two things to focus on – presentation and usability.  Not by any great stretch of the imagination, one could design a great BIOS for everyone to use – with an infinite color palette and tools it could look amazing.  However implementing such a system could be tricky, as a BIOS is currently limited to approximately eight megabytes in size.  This has to contain all the initialization parameters for the board, as well as all the BIOS options we get to play with.  I can imagine that should that limit ever increase to 16 or 64 MB, we would have a lot nicer things to look at.

I could wax lyrical about what I want in a BIOS, but as it currently stands, we will never get a work of art or functional awesomeness.  ASRock make a fair attempt, one of the better ones in fact, and it turns out to be easy to use.

The main screen shows the BIOS version, CPU, memory and frequencies.  What would put the cherry on the top would be the CPU voltage and temperatures as well.  If there is room, perhaps some fan speeds (similar to ASUS’ EZ mode) should also be included.  The main screen also has a system browser element, which is a top down view of the board with details on what is plugged in.

Overclocking options are essentially all bunched in one list in the OC Tweaker menu:

Important options like the CPU multiplier and BCLK are plain to see, as well as voltages and load line calibrations.  The ASRock BIOS had no issues in applying the XMP settings on my G.Skill DDR2-2400 kit of memory.

The Internet Flash utility is something new to consumer level BIOSes – ASRock implements this in their Advanced Menu.  If your motherboard is linked via Ethernet to the internet (thus on a network, or via ICS), then it will probe the ASRock servers for the latest BIOS.  It will then be downloaded and applied without hassle.  I really like this feature – it makes my life a lot easier at least!

Fan settings are all controlled in the H/W Monitor screen.  This shows temperatures, voltages and fan speeds, and gives options for the various fan headers on-board.  The main issue I have with ASRock fan options is the fact that they are not clear.  We should have all our options regarding temperatures and target temperatures – instead we get a ‘Level’ system.  This means that ASRock should probably invest in better fan controllers so they can talk back to the system regarding RPM, temperatures and relating these all to sensors on-board.

Software

ASRock’s software has not changed in any major detail since their last outing on X79.  At the heart of the system is ASRock eXtreme Tuning Utility (AXTU), which controls OS overclocking, fan controls, energy saving and XFast RAM.  XFast RAM itself allows 32-bit OS users to unlock memory not found, or 64-bit users to enable a RAMDisk to speed up certain caching utilities in the operating system.

Also from ASRock is the XFast LAN software, which in fact is a licensed version of cFosSpeed with ASRock decals.  This software allows full management of the network facilities on the motherboard – shaping traffic for different functions as well as monitoring tools amongst others.

XFast USB is another of ASRock’s licensed software bundled with each motherboard.  This utility will change the driver from the standard Windows one to one that can implement BOT (Bulk-Only Transfer) protocols.  In reality, this allows for quicker transfers due to less overhead, at the expense of latency.  For bulk transfers, I find that this utility works really well, especially with incompressible transfers.  The downside being that it is only applied to one USB port at a time.

    Are Q connectors proprietary of ASUS? I seem to find those only their motherboards. Love them to death.

    Great review. I enjoy these tremendously. Almost makes me go out and upgrade my i5 2500k.

    My MSI P67A-GD55 has the same thing, unfortunately the connector block is too tall and bumps into my second 6950 so I couldn't use it. Reply

    I, too, am a fan of the Q Connector mostly for the front panel connections (power, reset, HDD light). The USB and audio connectors seem to be pretty well standardized at this point, rendering those Q Connectors redundant IMO. This would seem to be a very simple and inexpensive feature for a mobo manufacturer to have (at least for the front panel connector). Reply

    Thank you for including this important benchmark. I hope that every motherboard review going forward will include this.

    The ASRock has the best time but 8 seconds is still too long. I wonder why BIOS developers can't get their act together and initialize hardware in parallel. That would surely speed POST times up tremendously.

    I've been struggling about that issue myself. I mean - it probably was in times of BIOS, but now, with all fancy UEFI is it really that hard? (considering more resources spent on bios/uefi in mobo)

    Altough I'm not big fan of 200$+ motherboards, I would seriously consider buying one if it POST in 2s.
    Even though there are probably POST requirements such as cpu cant be tested before ram or opposite it would be awesome to have really low boot times.
    Sad when even having SSD cant give You instant full boot (not hibernations/sleeps).

    It's one of those small features that are soo awesome (like reset/power buttons, and perhaps, in future : complete per component (ram/disk/SB/NB/coolers) power usage).

    Nevertheless 8seconds is damn nice.

    Does anyone know how enabling AHCI in the UEFI affect post time these days? I'd like to remove the other 7-10 seconds this adds to it. Reply

    How do those Chromebooks shave time off of the POST? Seems like similar techniques could be implemented unless there is a good reason not to. Reply

    Chromebooks use OpenBIOS IIRC. OpenBIOS is Linux Kernel based and boots very fast because it initializes things quicker and it's custom built to the hardware on the board. Personally I wish all the Boards would start using it and toss these BIOS down the hole of history. Reply

    They've got a very stripped down set of hardware to initialize. The more stuff you have on board, the longer it takes. EFI was supposed to fix this by allowing multi-threaded boot (BIOS was strictly a single threaded design); but either firmware makers aren't generally taking advantage of it yet, or dependencies in the startup process are limiting the gains.

    Don't forget the graphics card (if using discrete) will need to support UEFI (GOP) Booting too! Reply
