Everyone who cares deeply about Ethernet options will be pleased to see dual Intel Gigabit NICs onboard; however there is nothing too much to shout about in general in terms of what is available here.  Perhaps an additional two USB 3.0 ports on the back panel, or more SATA ports by a controller would be a welcome addition to the consumer product.

In The Box

Unfortunately, there seems to be a large discrepancy in terms of what’s in the box compared to my media sample and what exactly Intel are going to ship with the DX79SI.  Personally, I have:

Intel ‘Skull’ themed mouse mat
Two slot length SLI connector
Long SLI connector
Thermal Probe

In terms of what should be included, according to the manuals:

Bluetooth/Wifi Module
Driver CD
User Manual

Despite all this, we see a distinct lack of SATA cables provided.  With a significant proportion of HDDs being sold as OEM, sans cables, it is a shock to see a product without cables being provided. 


Again, for some reason due to this media sample, my range of installing drivers and software was limited to what I could download from the Intel pre-release website.  This required a manual installation of the chipset drivers, LAN drivers, USB 3.0 drivers, and so on.  While not exhaustive by any means, I hope the driver CD in the retail package has an ‘Install All’ option.

In terms of software, the only one currently available to me is the Intel Extreme Tuning Utility (XTU), which is essentially their overclocking software.  There are no fan controls for the OS, or ability to change the power modes here.  However, the XTU is a well designed piece of software with aesthetics to match.

The core piece of XTU is the manual tuning.  Almost all of the BIOS settings for the CPU are adjustable here in terms of sliders, with simple cancel buttons to return to default values.  Any changes you make here should turn up yellow, indicating a reboot is required to apply the changes (unless you select an option in the BIOS which allows you to change the CPU multiplier on the fly).

As mentioned previously, the lack of OS fan controls is one major aspect which lets this board down as an overall consumer product.  Hopefully this will change in future.

    I had no idea Intel made their own mobos. Reply

    *eye squint*

    Not sure if troll...

    I wasn't aware either.

    Granted, I don't really follow MBs much.

    They have pretty much been the world's biggest motherboard maker over the last 15 years or so. FoxConn used to make a lot of Intel branded motherboards in the past. Reply

    How can you not know Intel made their own motherboards? Even AMD at one point made a few boards to launch the K7 platform.

    I'm pretty sure Foxconn STILL manufactures Intel's boards, to Intel specification. All the components and connectors are usually Foxconn. You never see Amphenol and rarely see Molex-branded components. The PCB's usually have a Foxconn tag on an underside corner, indicating at least the PCB is manufactured by Foxconn.

    He has to be a troll. What do we call comments trolls leave? Troop (troll poop, or the stuff trolls leave)?

    The first motherboard available for the Core2 series for months was an Intel brand, followed by ASUS and whomever else.

    Or, maybe he's just an average tech user who browses a site like newegg and only knows of the more popular brands like ASUS, Gigabyte, etc. Intel may make a lot of boards, but that doesn't make them the most well known. Even I forgot until I read the article. Reply

    I guess anything is possible, but I have to negate it with the probability of an average tech user leaving the first post.

    While it's possible he could be just some average user browsing some article on a site that he's kind of familiar with, or that he really just hadn't heard about Intel boards, since they are more known for their procs (and now SSDs); there are many readers here that subscribe to the RSS, that are generally the first to leave comments. I guess what I'm saying is that it's highly unlikely some average user would leave the first post, whereas that is generally reserved for those that keep up with the tech news. What do you think?

    I just think you guys are being a little ridiculous that he's trolling and genuinely didn't know something. It's possible for even a more advanced tech user to have just never seen something before. Reply

    I have build over 500 PCs and only about 10 times have i used a Intel boards.

    All on request and 3 times it was for a server.

    It comes from the old days, when chipsets ware big influence on performance, as all Intel mobos from ware 5~10% slower the ASUS or Abit or whomever.

    But Intel never had a great name when it came to get the most out of there own chipsets!

    And if you go to a e-seller, you only find Intel boards, some ware hidden away.
    As there are people that prevere to have a "genuine" Intel board, from Foxconn ^_^
