ASRock Z77 OC Formula BIOS

With the ASRock Z77 OC Formula being around the top of the ASRock range (Extreme11 and Fatal1ty branding aside), we get the full meat of the latest BIOS on hand, with all the additional features ASRock likes to add in to its products.  Over the generations ASRock has dabbled in various faces of their BIOS, going from on old blue livery to what is now a nice looking feature with decent resolution images and no color conflicts.  Also in the pocket of ASRock is their Description window on the right hand side which informs users about the option they are changing.  Every BIOS should have one of these.

A few words about BIOS versions – for our review we used BIOS 1.80 as it is the latest public release.  Users will have to upgrade to above BIOS 1.30 if they want Multicore Acceleration, and to 1.60 or above for Windows 8 compatibility.  In order to keep things fair between reviews, I always update to the latest BIOS available to the public – no media or beta BIOSes which may influence results that the public never gets to use.

There is also a semi-important issue worth noting.  In an overclocked state using the Auto OC profiles, the BIOS does not reduce the system speed and voltage down to idle when no load is applied.  The voltage given to the CPU is constant, which could increase heat generation and power draw during those idle scenarios, albeit by a small amount.

To the BIOS itself, and unlike most other BIOSes we are not greeted with an easy mode for those new to the BIOS.  We get straight to the heart of the BIOS in the Main tab, which gives us some of the vital information I expect all boards to share on entering the BIOS: the motherboard model, BIOS version, the CPU installed, the speed of that CPU, the memory installed and the speed of the memory.  What is missing is some CPU temperatures and perhaps a rundown of the important voltages, just as a quick visual check.  In the Main tab we also get an option to adjust which screen we see when entering the BIOS – useful for competitive overclockers to go straight to the OC options upon entry.

With the board being called the Z77 OC Formula, the OC Tweaker tab is where all the action is.  In this tab our options are split up into suitable sub headings which all make sense, and every option available gets an explanation in the description box.

The first set of options gives us the Automatic OC list from ASRock in-house overclocker Nick Shih.  This opens a menu to give options between 3900 MHz and 5000 MHz in 100 MHz increments for an i7-3770K, along with an option to get 5565 MHz if you are running sub-zero temperatures (this setting is not recommended unless you are using dry ice/phase/LN2 on the CPU).  For a full rundown of these options, check out our overclocking section of this review.

The OC Tweaking and Super Pi 32m tweak are options specifically for competitive benchmarking, but if a user wants to manually adjust the overclock, the options below the CPU configuration heading are the place to start.  We can adjust the CPU ratio either per core or all cores, along with the BCLK.  MultiCore Acceleration is ASRock’s term for applying the top turbo bin on the CPU while at stock – any change in the CPU Ratio will cause this to disappear as it will not be needed.  Other standard options relating to SpeedStep and Power Limits are also in this menu.

The memory options allow for XMP settings, changing the memory straps, and DRAM configuration.  In terms of subtimings, the OC Formula allows a significant amount of timings to be adjusted (most of which I still don’t understand), but perhaps not as many as some rival boards.

The voltage options are also substantial enough to have fun with.  Aside from the normal voltages and Load-Line Calibration options we get on most Z77 motherboards, options such as PWM Switching Frequency and PCH voltages are also available.  When selecting one of the Nick Shih overclocking profiles, all of these are adjust automatically to take into account almost every CPU out there (though your mileage may vary).

Moving on through the BIOS we get an Advanced Tab which offers all the other system configuration tools for onboard controllers, storage, integrated graphics, audio, RST et al.

The Tool tab is something newer on the ASRock front – over the past 12 months ASRock has been adding new features like the System Browser, Online Management Guard, Dehumidifier and Internet Flash.  These were dotted around the BIOS, but now ASRock have placed them all under one menu:

The System Browser is a 2D version of Gigabyte’s 3D BIOS, except instead of offering options for each of the areas of the motherboard, ASRock uses this to determine whether installed components are actually detected by the system.  This is really useful if at random a SATA device is not found or a memory stick stops functioning – take a look in the System Browser before opening the case to see if the BIOS still recognizes it is installed.

As noted in the Z77 OC Formula overview, the motherboard has a total of thirteen motherboard temperature sensors as well as those used for the CPU and chipset.  The Multi-Thermal Sensor option in the Tools tab lets you see where they are, and hovering over each one gives a temperature readout.  All that is missing is perhaps a heat map generated by the values produced.

The Online Management Guard (and badly punned acronym OMG) in the Tools menu allows users to be able to disable network access for given times of the day.  This applies to all users, meaning if you want the children off the internet at 9pm, no-one can go on until OMG says so.  This is despite the fact that it is not password protected, and anyone can navigate into the BIOS to change it.

Also in the Tools tab is the option to update the BIOS, either by a file on an attached USB stick, or through the Internet.  The BIOS will probe the local ASRock server for the latest BIOS update and perform the process automatically for the user.  The main limitation is that the machine needs to be directly attached by Ethernet to the DHCP router in the property – no WiFi or ICS allowed.

All the fan controls get placed in the H/W Monitor tab:

Along with all the temperature sensor readings (notice the motherboard sensors are only to the nearest degree), we get our basic options for the fans.  These options by default are all placed on 100%, but can be adjusted following the old ASRock system of target CPU temperatures and target fan speeds.  The OS controls for fans are a lot easier to use and offer a greater selection of options.

Elsewhere in the BIOS are our booting options, with an option for Fast Booting when using Windows 8.  All that we are really missing is a Boot Override option to allow for a single time boot from a selected device.

    In the gaming benchmarks the ASRock Extreme4, $100 cheaper, gets the same result, even after the massive overclock on this board. While the overclocking is impressive, you can get a decent overclock with any cheap Z77 motherboard, and spend the difference in price on a better on a better video card, or the next grade of processor.

    I'd like to pass along my own experience with ASRock Customer Support. Cutting to the chase, it was entirely positive. I had obtained the review sample of an ASRock board from another site, which meant there was no warranty coverage. Unfortunately, the board died in the middle of a game. CPU temps were good, and I'd not [yet] had any reason to OC. Although I'd kept it at stock, it was a mini-ITX in a PC-Q08R, and the presence of a HD7870 in the build may have allowed something on the board to overheat, despite the pair of case fans. Anyway, I initiated an RMA request, fully explaining this situation, not trying to avoid their $50 service fee for out-of-warranty products. All correspondence was by email, and was handled quickly, with same or next day (if late) responses. I did pay the fee, but the RMA was handled quickly, and the new board is now just waiting for a brain (I used the original i5-3570K CPU in another build). Reply

    Ian, you are a MOTHERBOARD MADMAN!!! I can't keep up, but I try anyway.

    Sincere THANKS for these recent reviews. Wow.

    I like this board. In fact I like ASRock more and more. I remember the old days when their entire lineup was silly looking, bad performing boards. Those days are gone now and that is great. But that is not the point of this comment.

    The point is to say that I'm feeling a bit offended by having to read through the same bloody lines, once at the very beginning, and again at the very end of the article. Great technical knowledge Ian, but have some kind of respect for yourself and your work, and don't copy\paste the same lines from the first to the last page. What happened, ran out of things to say? Embarrassing and outrageous for someone who takes the time to read through your entire piece.

    I see that you are finally testing for some idea of sound quality, and I am quite grateful, but why aren't we hammering on these companies over missing features here? I care about one thing and one thing only; Dolby Digital Live encoding. I don't see why I should be forced to by a $150 Creative labs POS just so I can use the fiber connection for my 5.1 audio.

    This is a feature that was available as far back as the Nvidia Nforce 2 for crying out loud! Why is this not standard on $200+ motherboards? It cannot be that difficult, and I am sure there are more than a few gamers out there that would be happy to see this.

    As of right now, the ONLY motherboard on my radar is the Gigabyte Sniper 3. Sadly, they used a Creative chipset to get the job done, but at least it is built into the board.

    Anand, could you possibly reach out to these manufacturers and get them to understand people want this? The worst part, is that it is quite obvious there is very little in licensing costs involved, if Creative is anything to go by ($5 to get DDL on your current product!) and that is money well spent.

    Would you be interested in B75 with a Creative chip? Drop me an email with specifics. I'm not an audio nut (tone deaf too), but I can pass on some info :)

    I was very close to picking up the Z77 OC Formula. The only thing that I didn't like was that tiny fan for the VRM. I've had an Abit board before with the southbridge fan and about 2 years in, it started to get louder and louder until all you hear is grinding noise. Issue was that whole assembly was proprietary and replacing the fan means replacing the entire heatsink. Since then, I've vowed not to get any mobo that needed a fan of any kind.

    My question is.. do the VRMs get that hot that they require active cooling? I mean no other boards, including that monster Gigabyte UD7 needed fans? Or is it just for show.. if so, it is a retarded move. Second question, is it like a standard 40mm fan that can be replaced easily? If not, is the board still stable with NO fan attached.

    To the poster above wondering about the Sniper board.. I have it and that audio is the best I've ever had from a motherboard. I have a Gigabyte board with Realtek 889 audio and the Core3D just crushes it in every way. Now I haven't heard Realtek 898 on my sound system, so I can't compare.. but I'm really blown away by the sound. Not really impressed by Killer NIC though.

    The VRM fan is predominantly there in case (a) low air flow situation, like a closed-loop liquid cooler, or (b) hot ambient climate. You are perfectly justified in taking the connector out if neither of those apply to you. VRMs during normal stock usage are easily cooled by cross air flow, but as you start hitting 4.8 GHz+, they might start kicking out some heat if you are constantly hammering the CPU with loads. A small 40mm fan probably doesn't do much in that case, but it does something.

    With regard to the UP7, they use IR3550s, which are designed to pump out less heat for the same power - and there's 32 of them, so the heat generated is spread around such that the long extended heatsink can take care of everything.
