Intel Atom DG945GCLF Motherboard

Just built a mini ITX PC using one of these motherboards. The motherboard has one of the Intel Atom processor onboard (230 clocked at 1.6Ghz). Probably the most remarkable thing about this processor is its power consumption of around 5W. The motherboard does have a fan, but it is on the graphics processor and not the CPU.

The motherboard was bought from Tranquil in the UK and set me back £42 (excluding VAT and delivery). I fitted it into a Noah 3988 case with a 500GB 7200rpm SATA drive, 1GB RAM and a slimline format CD/DVD drive. It is powered by an external power block and DC-DC board.

This combination is very quiet and produces so little heat that I could probably disconnect the fan in the case, leaving just the fan on the graphics processor.

I installed Vista Ultimate onto the machine. It installs without any issues and the CD that is supplied with the motherboard contains all the relevant drivers. The CD even recognise that it was installing on a Vista machine. The aero UI on Vista came up first time with the drivers on the CD. The network also installed without any issues. The audio took a little more fiddling with to get it to work.

The screen capture above shows the performance figures that I got out of the machine once I had installed the drivers from the CD enclosed with the motherboard. There is a definite improvement in video performance with these drivers - the graphics increased from 2.0 to 4.2 and the gaming graphics increased from 2.4 to 2.8.

When running Vista, this unit is pulling between 30-40W (most of the time it runs at about 33W). Exactly the same configuration with a D201GLY2A motherboard (Intel Celeron processor running at 1.2GHz) pulls about 40 - 50W (averaging around 45W). Because the Intel Atom is generating less heat, I unplugged the internal case fan. In hindsight, this was pretty pointless - it saves about 1.5-2W and makes very little audible difference to the running of the unit.

With this configuration, this unit is pretty quiet and would make an ideal candidate for a small format Vista Media Center. However, the motherboard's very limited video output capability (a single VGA connector) probably limits it's use in this department. Personally, I have been using the Linksys DMA-2200 Media Extender to connect to my TV via HDMI. So the lack of video connectivity is less of an issue.

I have a Hauppauge Dual Tuner TV USB stick that I will put into this machine and test out in the next few days.
