ASRock Z87M OC Formula Software

As mentioned in the Z87 Extreme6/AC review, one area that ASRock needs to focus on more than any other is Software.  In previous generations ASRock likes to push forward their XFast system – RAM, USB and LAN.  Each of these technologies is always advertised as offering 5x performance, although specific selection of benchmark and testing for each often helps that claim.  Over a number of reviews we always analyze these features, and all three of the XFast range can generate a positive buzz for ASRock.  In terms of the standard software package with the Extreme6/AC, the OC Formula gets a bump with corrected spelling, more accurate voltage reporting, and overclock oriented memory configuration.  One thing missing in the ASRock software stack is an auto updating service, which we will no doubt see over the next year or two.

Installation of the drivers and software from ASRock has been good for the last few generations, often requiring one click to install everything (after a deselection screen).  The sole issue I usually have with these systems is the inclusion of 30-day trial anti-virus software from big companies that most enthusiasts like to uninstall.  This option gets deselected when I test the motherboard, but I always have to scroll down to deselect it. 

For the Z87 platform release, ASRock have decided to re-skin their software to bring it more into this decade.  Instead of the ASRock Extreme Tuning Utility (AXTU), normal motherboards get A-Tuning, and OC motherboards get Formula Drive, which opens up with automatic overclocking options:

By default we are in Standard Mode which is the default method of operation.  In Performance Mode the system essentially moves into ‘High Performance’ power mode, offering 39x CPU multiplier at both idle and any core loading.  In Power Saving mode the system reduces to 8x when idle, and then under continued load slowly ramps up the CPU speed to the full 39x.  This process takes about 5-8 seconds of constant load to reach the top speed ensuring that short operations do not cause the CPU to draw a lot more power than required.  When Performance Mode is selected, an additional option ‘Auto Tuning’ is given which performs a tuning based automatic overclock – we go over this operation in the Overclocking section.

The Tools menu is next, and l would assume by the amount of whitespace and the size of the buttons to be the area where future ASRock ideas are implemented:

X-Fast RAM

The first up is XFast RAM which gets a new interface but performs much the same operation as last generation – partition an amount of memory off for cache and temporary files.

Good Night LED

The Good Night LED menu option allows users to disable any lights on the motherboard or connected to the motherboard when the system is in operation.  This allows users who have to leave their PC running overnight in the same room in which they sleep to not be distracted by the lights on their PC.

FAN-Tastic Tuning

In order to mitigate the noise of the fans, or produce a fan profile suitable for overclocking, ASRock have a fan control system that actually implements how a fan control system should work, even on 3-pin fan headers!

With the fan options, users can get the software to test the fan to find its power-to-RPM profile which ASRock then translates through software into an 8-point gradient graph of Fan Speed vs. temperature.  This is 95% of what fan controls should be!  The only thing missing is a small amount of hysteresis – fan speeds are kept at the high speed as the system cools down in order to help the system to cool down quicker.

Dehumidifier Function

The Dehumidifier function is one from last generation, offering users in humid climates to keep the fans attached to the motherboard on for a fixed amount of time after the PC is shut down.  This allows the air inside and outside of the case to equilibrate faster – users in these climates can suffer from condensation if the air in the case cools down and the water saturated air causes the water to form droplets on the inside of the case.  This function helps keep the temperature inside and outside the case constant after shutdown, meaning if there is an issue for condensation it would apply to the whole room, not just the case.


One of the new features on ASRock’s motherboard range is the inclusion of a HDMI Input on the rear IO.  The purpose of this is to have an all-in-one entertainment system on the desk.  Imagine having a PC and a console on the desk – this would require two inputs into the monitor plus extra cables around the rear of the monitor.  With HDMI-In we can plug the console into the PC and then use a hotkey in the OS to switch between the two.  I was unable to test the feature as I do not own a console (I sold them all), but one thing about the HDMI-In software I found was that there is an invisible window present at run time.  This can affect options such as ‘Show Windows Side-by-Side’, as it includes this invisible window.  It is also selectable by alt+tab.

OC Tweaker

For manual overclocking in the OS, ASRock has skinned its OC Tweaker in the new style.  I like the fact that the options are now easier to see and manage, although ASRock are missing the ball by not including the ‘current’ values alongside the ‘adjusted’ ones.  This would allow users to see what is currently selected against what is currently applied.  A simple menu alongside an advanced menu would be a nice addition, as well as a series of information in the whitespace to the right showing default values.  A lot of motherboard manufacturers are also offering inputs by typing as well as sliders, which is something that ASRock may want to look into for the future.

The information for the system is under System Info, which acts more like a Hardware Monitor:

One flaw that has been fixed is the CPU Voltage reported.  Previously on the Z87 Extreme6/AC, it would the CPU VIN voltage (from the FIVR) rather than the voltage actually being applied to the CPU.  This is now fixed.

Timing Configurator

Despite the reasonable assumption that memory suffers from the effects of hitting the limit of diminishing returns as you improve speed for real-world performance, overclockers love squeezing as much synthetic performance out of memory that is physically possible.  ASUS have had their MemTweakIt tool on the last few generations of ROG boards, and ASRock have their second platform now with Timing Configurator which allows users to adjust memory timings on the fly.


One of the more long-standing positive features in ASRock’s product stack is XFast USB.  The premise is simple – the Windows 7 USB driver is not as optimized as it could be.  With XFast USB ASRock are implementing a BOT driver to both USB 2.0 and USB 3.0 which improves USB peak speed at the expense of latency.  In our USB testing we see this as a large improvement in terms of both peak and real-world speeds.


ASRock bundle a licensed and skinned version of cFosSpeed to help with network management.  XFast LAN allows users to give certain programs a higher priority over others, meaning they are rearranged in the Windows network stack appropriately.  XFast LAN also offers extensive analysis of network traffic, although as this is all a software implementation, could arguably increase CPU loading.

    Who overclocks anymore? Better off to just save your money and buy the next CPU up IMO.
  • Horza - Wednesday, August 14, 2013 - link

    So if I buy a 4770k and overclock it to 4.5hgz (kind of the point with the K series) what's your advice?

    Overclocking is an easy way to get some free performance and can be a bit of fun at the same time.
  • Pessimism - Wednesday, August 14, 2013 - link

    Since you're already at the top end for desktop parts, my advice would depend on what task you perform that saturated the 4770K at stock speeds.
  • RealiBrad - Wednesday, August 14, 2013 - link

    So if I'm a gamer, its better for me to buy an I7 over an I5, even though I can get an I5 and OC it past the base performance of any I7.

  • Pessimism - Wednesday, August 14, 2013 - link

    You will spend more on the rest of the computer to do it than if you had bought the i7 in the first place. You will also spend more on electricity to power your PC. Yes you will gain a little CPU capacity over a stock i7, I can't deny that. However you haven't provided any example of an everyday gaming or computing scenario that saturates an i7 and justifies all the extra expense, energy consumption and hassle. Don't get me wrong, I was clocking the snot out of a 2500 Barton back in the day like everyone else, I just think the cost/benefit ratio isn't there anymore when you look at how far hardware is past software right now.

    Starcraft II. I can bring my 4.6ghz 4670k to its knees in real world scenarios if I want too. That wasn't hard :P
  • karasaj - Wednesday, August 14, 2013 - link

    Real world scenarios being team games and intense 1v1's.

    "All the extra expense"... how much do you think it costs? With an unlocked multiplier on the CPU's, its quite easy to overclock and doesn't incur much added expense. Any halfway decent motherboard that has the features you want on it is going to be fully capable of overclocking quite a bit anyway. The electricity difference is going to still be there, but is probably fairly small.. Maybe 20-30W ? With TDP's on the Intel chips these days, it really doesn't take a big cooler to cool them, even if overclocked. A CM Hyper 212+ can be bought for something like $20 and does the job really well. Lots of people would be buying an HSF capable of handling the additional heat anyway. You could easily build a rig capable of overclocking for less than it would cost to jump to a high-end i7 and get equal or better performance.
  • RealiBrad - Wednesday, August 14, 2013 - link

    So if I'm building a new system, and the game I'm likely to play will have a cpu bottleneck with an i5-4670, its cheaper for me to spend more on upgrading to a locked i7-4770 for $90 more and get a few frames increase at best? Why would it not be better to take that same $90 and get a i5-4670k and a mobo that can adjust the multiplier? If an i5 is bottlenecked then getting any locked i7 will do nothing. Its far better to get an unlocked i5 and OC it to reduce the bottle neck. yes, the mobo will cost a little more, but the jump from an i5 to an i7 is still more expensive than getting a i5 k and mobo.
  • IanCutress - Wednesday, August 14, 2013 - link

    It depends what you do. If you overclock and get another 25% performance, that enables you to complete 5 tasks in the same time as 4. If the reward for doing that task is more than the cost of the electricity, then it's a no brainer. This is particularly relevant in the financial industries, where every millisecond counts, or for careers that are throughput limited.

    That's just for workloads - gamers are often not worried about the cost of electricity when it comes to pure performance, and overclocking to increase single core performance, particularly in games like Civilization V that respond well to overclocking ( result in a rise of FPS.

    There is also the aspect of competitive overclockers, who see it as a challenge to out-overclock their competitors. As mentioned in the review, this is one of the target groups for OC-oriented motherboards, and the motherboard needs to have features to appeal to this crowd.

    Just because you do not overclock anymore does not mean that the activity is dead/no longer useful. It is alive and kicking - the amount of pre-overclocked systems on sale today is just one prong of this.
