The IGP Chronicles Part 1: Intel's G45 & Motherboard Roundup

Intel DG45FC
We looked forward to the arrival of this motherboard with great anticipation. It is not every day we have the latest IG chipset available in a mini-ITX form factor. We heard rumors of this board at CES last January and were actually surprised to see it on the roadmap in April and even more surprised that Intel built this board. As such, we will take an in-depth look at it and supporting components such as cases and power supplies shortly.
For the time being Intel has done a remarkable job shoe horning the G45 into this particular form factor. The DG45FC offers an excellent feature set that includes Intel’s 82567LF PCIe Gigabit Ethernet controller, RAID 0,1,5,10 support from the ICH10R, IR capabilities, and HD audio from the IDT 92HD73E featuring Dolby Home Theater certification. Considering the cost of most mini-ITX boards, the street price of $129.99 is astounding.
We like the layout of the board. It features a three-phase power delivery system that worked well with our selection of dual core processors. Quad Core processors are not supported but considering the processing power available in an E8600 for instance, it should not matter for most users considering this form factor. Like the DG45ID, this board is legacy free. There are four SATA ports located on the board and an eSATA port on the IO panel that also contains six USB 2.0, LAN port, and the HDMI/DVI output ports. There are two headers on the board for an additional four USB 2.0 ports, one PCIe x1 slot, and two DIMM slots that support up to 4GB of memory at DDR2-667/800 speeds.
Actual operation of the board was similar to the DG45ID. The BIOS (version 079) is the same one offered on that board and as such all of the comments we discussed in the DG45ID overview holds true for this board. We are still searching for the perfect case to install this board in to be honest.
We utilized an Apex M-100 for initial testing. This case does not offer the best ventilation so our current thermal numbers are skewed to some degree. It also requires the use of a low profile CPU fan/heatsink like the ones shipping with the E7200/E5200 processors. Installing the retail fan/heatsink is a bit tricky but it works. The lack of a heatsink on the ICH10R resulted in temperatures hitting the 65C~70C range in this case. Airflow was partially blocked by the hard drive so the MCH ran upwards of 80C with the E7200 at 42C. We did not encounter any stability problems but would like to see reduced temperatures for 24/7 operation. We will be looking at other case and thermal solutions shortly.
Pros/Cons
We really want to like this board; in fact, we do to a certain extent and it excites us from an HTPC viewpoint. It carries all of the baggage of the DG45ID board with it due to the BIOS design and hardware compatibility problems. Like all of the G45 boards, it is also saddled with drivers and ISV support that is still lacking although improving with each release. We think Intel should have included a small heatsink on the ICH10R although proper case airflow is still a requirement for keeping the MCH and ICH at tolerable levels.
Changes we would make would include the ability to manipulate processor voltages, a more robust fan control system since this becomes extremely important in a mini-ITX design, a thermal solution for the ICH10R, and figuring out a way to include IEEE 1394a support would have put icing on the cake. Overall, the price and performance for a mini-ITX platform is just incredible. If Intel can straighten out some of the BIOS, driver, hardware, and BD playback compatibility problems, this board would be our choice for a HTPC or SOHO solution in the current market space.

I'm not sure why this board is measured/reviewed for its gaming ability (or lack of). A lot of HTPC peeps get these because they are quiet and can play DVD's without the noise /heat. Not many people really expect to play Oblivion on it.8steve8 - Wednesday, September 24, 2008 - link
the dg45id has the unique ability to ouptut simultaniously to two displays with a digital interface.imo its the prefect board for non-gamers with dual-monitors..
seriouosly.. analog sucks.
should be listed in the pros/cons.

Yes, a very important feature for a work system with integrated graphics. Presumably common to all G45 boards with DVI and hdmi?yehuda - Saturday, September 27, 2008 - link
No, the Gigabyte board can't do that even though it has both ports.http://download.gigabyte.ru/manual/motherboard_man...">http://download.gigabyte.ru/manual/motherboard_man... (p. 8, footnote 1)

SPCR measured the power consumtion of the same mini-ITX G45 board and found it to consume 35W at idle with an E7200 CPU installed (which should consume a tiny bit more than a 5200, given it works at higher FSB speeds and has more cache).Your figures showed something like 57W; one would say, hey, no big deal, we're talking about only 22W here. But if you take this as relative difference - it turns out to be 60%! SPCR used only one DIMM, but I doubt this can explain the discrepancy. The PSU was a 400W model, so I guess it has similar efficiency curve as the Corsair model you used.
Given the strange results of you power consumption measurements recently, I have reasons to doubt that something simply isn't right out there.

SPCR people will make more efficient choices. Efficient PSU, notebook hard drive, non-overclocked RAM. 57W is a good result for a mainstream review. Little things can add up to 22W, especially PSU efficiency.MadDogMorgan - Wednesday, September 24, 2008 - link
ANAND! These vibrant media popups are KILLING ME!!!!I am about ready to GO INSANE reading your site. You CAN'T POSSIBLY be making any MONEY off those things, they are too INCREDIBLY ANNOYING for anyone to ever THINK about watching one or clicking one.
Oh, and I LIKE PS/2 ports. What's wrong with PS/2 ? It works great, takes less cpu than USB (in my VERY informal mouse testing) and the headers take up very little space on the mobo. You also have the option to use the USB connections instead, if you want.

Wow, thank you! Now how do we do that on DT?MadDogMorgan - Wednesday, September 24, 2008 - link
Thank you VERY MUCH for providing this option.Also, please keep up the good work and I appreciate you spending some time in the HTPC area. It seems to me there is a decided lack of good technical coverage in this arena. The kind of in-depth coverage that only your and a couple of other notable sites provide.
I would like to see some TV Tuner card reviews from your site comparing the technical details of the latest offerings from Hauppauge, ATI and any other popular ones. Toss in a review of a few PVR apps like GB-PVR, SageTV, MythTV and BeyondTV and (HTPC) life would be complete. Don't forge to address the difficulty of getting the channel listings when using a freebe like GB-PVR, or the ins and outs of getting scheduled recordings to actually WORK when the app uses the Windows Task Scheduler.
Thanks Again.
