ASRock Z87E-ITX In The Box

It would be easy to predict that a $150 mini-ITX motherboard has the bare essentials included in the box – at a guess we would expect a couple of SATA cables as a minimum.  The Z87E-ITX goes a little further, giving:

Driver DVD
Rear IO Shield
Four SATA Cables
WiFi Antenna
DVI to D-Sub Adapter

Some motherboards use a built in antenna, but ASRock offers their own version here, designed to hang from a high spot above the system.  Aside from the two extra SATA cables, it is a little surprising to see a DVI to D-Sub adapter included, but welcome nonetheless.

ASRock Z87E-ITX Overclocking

Experience with ASRock Z87E-ITX

ASRock have developed their overclocking methodology over the generations, now offering a good number of 24/7 automatic overclock options both in the BIOS and in the OS.  These auto options are aggressive with voltage in order to encapsulate as many CPUs as possible, but even with an H80i on the path to winter, some of the options near my CPUs limit were hitting temperature boundaries.

Nevertheless I was impressed that ASRock’s settings all worked on my CPU, albeit a little overloading at 4.8 GHz and 1.42 volts.  During the manual overclock testing I did not notice ASRock requiring less voltage than other Z87 motherboards tested, however it did eclipse 4.7 GHz with temperatures remaining under 90C and 4.8 GHz failing only due to high temperatures.  Whether this was due to ambient temperatures being slightly lower than in previous testing or not, it is still a good display of overclockability from a small form factor product on server level power delivery chokes.


Our standard overclocking methodology is as follows.  We select the automatic overclock options and test for stability with PovRay and OCCT to simulate high-end workloads.  These stability tests aim to catch any immediate causes for memory or CPU errors.

For manual overclocks, based on the information gathered from previous testing, starts off at a nominal voltage and CPU multiplier, and the multiplier is increased until the stability tests are failed.  The CPU voltage is increased gradually until the stability tests are passed, and the process repeated until the motherboard reduces the multiplier automatically (due to safety protocol) or the CPU temperature reaches a stupidly high level (100ºC+).  Our test bed is not in a case, which should push overclocks higher with fresher (cooler) air. 

Automatic Overclock:

Options for automatic overclocks are available in both the OS and in the BIOS.  For OS overclocks, we have the front page of A-Tuning:

In Standard Mode, the system operates as per the normal settings.  We observed a load voltage of 1.021 volts, a PovRay score of 1531.55 and a peak temperature of 55ºC.

In Power Saving Mode, the system reduces down to 800 MHz for almost all operation.  Under sustained load (any number of cores), the system will raise the CPU speed slowly.  After eight seconds the system will be at full speed, offering full stock performance.  Due to this ramp up procedure, the PovRay score was lower at 1438.95, but load voltage was the same at 1.021 volts.  Peak temperature under load was 56ºC.

In Performance Mode, the system stays at the full-load turbo bin as set in the BIOS, rarely coming down to idle unless the system is absolutely idle.  In our system this meant a 3.7 GHz speed, giving a PovRay score of 1517.43 and load voltages of 1.021 volts.  Peak temperatures were at 56ºC.

This screen also offers Auto Tuning, which set the i7-4770K CPU at 3.0 GHz and stress tests the system, upping the multiplier over time to 4.3 GHz.  At 4.3 GHz the system stops as if complete.  At this setting the CPU voltage is set to 1.200 volts, giving a load CPU voltage of 1.202.  Unfortunately the system was only at 4.3 GHz for single thread loads, moving down to 3.5 GHz for multithread, giving an ultimate PovRay score of 1472.88.  Peak temperatures were 67ºC due to the higher voltage.

Overclocking via the BIOS is comparatively easy, with the ‘Optimized CPU OC Setting’ giving options from 4.0 GHz to 4.8 GHz in 200 MHz jumps.  The latter two options are in red, suggesting a better than average cooling system.

  • At 4.0 GHz, the system applies an adaptive 1.000 volts on the CPU, giving 1.064 volts under load and a PovRay score of 1641.82.  Peak temperatures under load were 59ºC.
  • At 4.2 GHz, the system applies an override 1.200 volts on the CPU, giving 1.202 volts under load and a PovRay score of 1740.26.  Peak temperatures under load were 71ºC.
  • At 4.4 GHz, the system applies an override 1.300 volts on the CPU, giving 1.297 volts under load and a PovRay score of 1825.93.  Peak temperatures under load were 84ºC.
  • At 4.6 GHz, the system applies an override 1.320 volts on the CPU as well as a Load Line Calibration level one and 1.9 volts on the FIVR, giving 1.321 volts under load and a PovRay score of 1897.05.  Peak temperatures under load were 88ºC.
  • At 4.8 GHz, the system applies an override 1.420 volts on the CPU as well as a Load Line Calibration level one and 1.9 volts on the FIVR, giving 1.421 volts under load and a PovRay score of 1961.48.  Unfortunately temperatures during PovRay reached 99ºC, and our OCCT load test failed due to temperatures.

Manual Overclock:

For our manual overclock testing it was easy enough to follow the same principles of the CPU OC settings and extrapolate to find the lowest voltage needed for each CPU speed.  We adjusted the multiplier from 40x upwards, starting at 1.000 volts with 1.9 volts on the FIVR and a Load Line Calibration of level one.

The fact that the motherboard hit 4.7 GHz on my CPU (and kept OCCT under 90ºC) that commonly falls foul at 4.7 GHz is a pleasant surprise.  With any luck I will get my new water chiller loop system to help push systems beyond ambient limitations.

    I bought one of these a while ago and it really is a good motherboard. I was having some issues with 1.35V RAM at first, but UEFI version 2.10 cleared that up for me. The Bluetooth part of the 802.11ac/BT module gave me issues as well, but that was all driver-related. Even still, I swapped it out for an Intel part that's performed much better.

    My biggest issue with the motherboard though, is I really can't believe that Asrock removed their consumer IR header in this generation. I know it's a very niche thing to need, but it'd be perfect for my gaming/media PC. And there's still space for it in the spot it used to be in, they seem to have just decided not to include it this time.

    I have the H87 version of this board, and had the same exact problem with 1.35v RAM until the August BIOS update v1.5. That BIOS also fixed a crazy Windows 8.1 (beta at the time) problem causing the event viewer to log a ton of disk IO errors that were in actuality, inert.

    So far ASRock support has been exceptional. I'm traditionally an ASUS user (and use an Asus H77 ITX board in my file server with a Areca RAID controller) and the BIOS is nearly identical to ASRock. The ASUS software, however, is slightly more "professional" looking, but the XFAN utility and other tools function virtually the same. They're the same company, after all.

    But the only problem with the H87 version of this board is four SATA instead of six. Not a problem for my tiny case, but it could be an issue for people with a lot of drives (like a BitFenix case, etc)

    "So far ASRock support has been exceptional."

    I find this hard to believe. I've got an ASRock A75M-HVS as a file server, booting via UEFI. They released a firmware update for Windows 8, which broke UEFI booting for me, so I had to roll back to the older firmware. I emailed their support about it multiple times and never got a response other than their automated "we have received your email and will contact you soon".

    The Gigabyte A75 chipset boards have UEFI problems as well, so I think it is more an FM1 chipset problem than a board manufacture problem. But then again, Gigabyte isn't always great with their support either.

    To be fair to AMD, the A75 was their first chipset to support UEFI so it isn't a shock there are bugs here and there in the same way there were TONS of issues migrating Z68 boards to a UEFI BIOS (many didn't ship with UEFI so it was added to later BIOSes and that was a mess, especially once again for Gigabyte.)

    Speaking from experience, Asrock do offer excellent support, even on their budget priced boards. I built a number of workstations using the (almost) mini-itx sized G41-VGS3, and after a while noticed that AsRock were releasing updated BIOSes for similar models but not this one. One update improved significantly the CPU fan speed management, something which my users would've appreciated. I e-mailed them and the next day they had sent me a BIOS file with all the updated (including the fan speed) from other models. It flashed flawlessly and considering the rock bottom price, I couldn't be happier. Reply

    Asus spun ASRock off several years ago, along with Pegatron. Reply

    Do the eSATA ports and mSATA ports take away from the 6 ports on the board, or are they in addition to the 6 ports?

    From the look of it, you're limited to 6 devices total, e.g. 1 eSATA, 1 mSATA and 4 regular or 6 regular and no e/m?
  • jhoff80 - Wednesday, November 6, 2013 - link

    They take away from it. 6 total. Reply
  • Ninhalem - Wednesday, November 6, 2013 - link

    Do you have official documentation or something else that backs that up?

    I've been looking for a long time for a board that has 6 SATA slots and an mSATA for my home server.
  • kirk444 - Wednesday, November 6, 2013 - link

    the user manual will clarify it for you, but the eSATA and mSATA each share a physical SATA port on the board. You are limited to 6 SATA devices.

    What I've done, is stick a 2 port SATAIII MiniPCI-E HBA into the top-side mPCI-E slot. (I am not using the wi-fi/bluetooth).

    I've seen conflicting reports on whether the back-side mPCI-E can be used without disabling the use of the mSATA associated SATA port. My very brief testing seems to show that even if you just use it as a mPCI-E (as in, shove the wireless card on the back side) that you still lose the SATA port. ASRock tech support told me otherwise, but I think they just misunderstood the question.
