DFI includes the Realtek ALC 888 HD audio codec, Intel 82578DC LAN (PCI-E), JMicron JMB363 eSATA, and full support for the Core i7/i5 S1156 processor series. Creative X-FI drivers are included in the package, but you don't get any kind of Dolby Surround sound processing features in the bundled software.

DFI bundles the following with the board:
4 X SATA Cables
2X SATA Power Cables
1X I/O Panel
1X User Manual
1X Driver DVD
1X Creative X-FI Driver CD
2 X Smart connectors for front panel I/O

One of the software tools bundled with the board is a very basic overclocking utility called EZ Tuner.



EZ Tuner allows on the fly changes to processor VCore and also changes to BCLK within the OS as well as monitoring primary voltage rails and processor power monitoring. There are no options for changes to VTT or VDimm unfortunately, although the MI-T36 is limited in the overclocking department anyway.

AS with all DFI boards you also get Smart Guardian.


Smart Guardian offers temperature and power monitoring as well as comprehensive fan speed control for both fan headers.


The BIOS layout is generally good and offers a significant number of settings for overclocking although some of the settings seem out of place on this board given the power delivery limitations. You get fine control over DRAM reference voltage settings as well as options for adjusting compensation levels to critical signal lines. The latter is a feature we've only seen available on the more expensive EVGA boards.


BIOS flashing is taken care of within the OS only, DFI include a little tool called EZ-Flash. We prefer BIOS level utilities personally, especially when there's no redundancy, as you've only got a single BIOS chip on this board.

    Is Gary Key still writing for Anandtech? I noticed he hasn't posted in a while and his email address @anandtech bounced the other day, though I've successfully emailed him there before and gotten responses.

    If he left, where did he go? His motherboard reviews were usually thorough, superb, and very much appreciated.

    (Your review is fine, I am just wondering what happened to Gary Key.)

    I can confirm that Gary left us to go work for someone else last month. I'm sure he'll still read the site, but his new job prevents him from writing for us now. We wish him the best, though!
  • yacoub - Monday, January 4, 2010 - link

    Ah okay, thanks for the update. I guess he's working for one of the companies who make products you guys review, not another news site? :)
  • JarredWalton - Monday, January 4, 2010 - link

    Yeah, I thinks it's okay for us to mention he's at ASUS now.
  • yacoub - Monday, January 4, 2010 - link

    Oh very cool! :)

    I like to see more reviews of mini-ITX. Cases and boards.

    This is the year of the HTPC.
  • DigitalFreak - Monday, January 4, 2010 - link

    Surprisingly enough, the price isn't bad. $134 @ Newegg.

    Hi anand

    Did you tell DFI about the reboot loop problem, S1 works fine but the GPU fan ramps up to 100% on S1 so it's unusable, and S3 has the aforementioned problem of random waking up and get stuck in a reboot loop.

    S3 is VERY important on an HTPC board imho. S4 works too but it's still too slow for day to day usage.

    If it can't be fixed guess I'll have to clock down to stock overclocking via software when gaming or get a passive cooled GTS250 instead of the current active cooled one.
