The ASRock CoreHT 252B package contained the following:

  1. Main unit in a 2.5L chassis (195mm x 186mm x 70mm)
  2. 90W AC / DC adapter
  3. Media Center remote with batteries
  4. Support CD with drivers and miscellaneous software
  5. HDMI - DVI dongle
  6. SATA and power cables / screws for user installation of second hard disk
  7. 3.5mm audio cable
  8. Anti-slip base pad for the main unit


The industrial design is nothing to write home about. The pleasing rounded edges are reserved for the higher end Vision series. The CoreHT series has to make do with a sharp edged chassis very similar to the first generation Core 100HT.

When compared with the Core 100 from last year, we find that two of the USB 2.0 ports at the rear end of the unit become USB 3.0 ports in the CoreHT. The front panel remains the same except for the structure of the ventilation slot which is now curved in (instead of the planar slots in the Core 100) and the shape of the power button is now circular instead of the square in the last generation unit.



Just like a notebook, this unit also supports simultaneous display on two monitors. Testing was done mostly with the HDMI output connected to a Toshiba REGZA 37" 1080p TV through an Onkyo TX-SR 606. For non-media playing related testing, the HDMI port was connected to an Acer H243H 1080p monitor.

Our review unit shipped with Windows 7 x64 Ultimate and a OEM version of Cyberlink PowerDVD for Blu-Ray playback. However, the OEM version doesn't support 3D Blu-rays and is also crippled with respect to the number of audio channels that can be decoded / HD audio passthrough. To test these, we installed the full versions of both Cyberlink PowerDVD 11 as well as ArcSoft Total Media Theater 5.

We will conclude this section with a table to summarize the data and A/V connectivity options for the ASRock CoreHT 252B HTPC.

    intel really needs to get their shit together re: dxva and hardware decoding for video Reply

    First I want to tank you Ganesh for the article. Keep the good work!

    Would you give us some more information please.

    Can it play 1080 60p?
    There are a lot of camcorders that can record in AVCHD v2.0 (1080 60p 28Mb/s).

    What are the temperatures (CPU HDD) inside during idle and 100% load?
    Why ASRock don't make CPU fan to blow outside the case as in notebooks?

    Can you select RGB or YUV output in new intel drivers?

    Yes, it does play 1080p60 without issues (even the Clarkdales and Arrandales can do it).

    The 1080p60 streams are part of our test suite. But, yet, you are right .. I should have mentioned it.

    The HTPC outputs RGB, and there is no obvious way to change it to YUV in the graphics control panel. However, the levels (0-255 / 16-235) can be modified with the Quantization Range option.

    I will get back to you on the temperatures in a day.

    Thanks Ganesh, is 1080 60p hardware accelerated? Reply
  • ganeshts - Friday, September 02, 2011 - link

    Yes, it is.

    Both 1080p60 and 16 reference frame H.264 videos were able to get DXVA2 hardware acceleration using the Microsoft DTV-DVD decoder.

    Here is the temperature info you requested (measured using the AXTU tool for the mobo and the CPU / HD Tune Pro for the hard disk in Celsiuis scale):

    Idle:

    Motherboard : 42
    CPU : 44
    Hard Disk : 37

    Prime95 + Furmark (after 15 minutes of activity):

    Motherboard : 48
    CPU : 83
    Hard Disk : 39

    I bought a previous generation HT100-BD and it was a fine HTPC but the ASRock service was appaling. The unit had two failed HDMI ports in the first 12 months and the second time ASRock demanded payment to fix it (even tough it was under warranty).

    As convenient as it may seem, I would go down the DIY route just for the flexibility of being able to fix it yourself.

    As paying the Windows Tax for a single purpose/ non-gaming machine is a bit pointless, I wonder how well the hardware in this box cooperates with Linux?
    I tried to build a HTPC on an older AMD platform and was continually being thwarted by driver issues (WLAN, sound, graphics), but here there actually may be an advantage, as Intel has a developer that manages libva, so their acceleration might work better on linux than DXVA..

    Also XBMC has a native linux version which is quite nice and should even boot faster in an optimized system than a Windows system.

    As you might have noticed, the box ships without Windows. You see, that's the difference between your "Windows tax" and other taxes: You don't have to pay it. You are free to install any other OS. If you stopped pretending otherwise, someone might actually answer your question... Reply
  • Rick83 - Friday, September 02, 2011 - link

    Well, the reviewer only used Windows, hence assuming that one pays for it.
    A Windows-only review is of little help for someone attempting to deploy linux on this box.
    If the reviewer implies the windows tax, by not mentioning alternatives, he is the one accepting it, I am merely referring to his point of view.

    Also, the alternative to the Windows tax is the Linux tax. The latter can often end up being higher....
