Low power motherboard/chipset advice
Hi,
I have been researching low power motherboards/chipsets for a system upgrade and am finding it difficult to get the information I need. Perhaps someone can provide some advice; or refer me to a website that compiles this kind of info.
I am trying to find the lowest power motherboard/chipset that supports some components that I want to re-use. This is for my ZFS fileserver (currently using Ubuntu, but I can swap to another Linux if needed). I have an AM2 Athlon x2 CPU, ECC DDR2 RAM and PCIe SATA2 controller. I currently use onboard graphics and gigabit ethernet because I assume they use less power than controller cards.
The idle power consumption is all I am really concerned about. The system is idle 95-99% of the time, but I can't sleep/standby it because of the server software it runs.
I really want to get the system to around 30W idle. Any suggestions/advice?
I'd swap to a dual core Atom solution, but it doesn't seem to support ECC.
Thanks,
Ty

I'm surprised nobody has a site recommendations or advice...
Perhaps if I be a little more specific. Does anyone know if the Nvidia chipsets and more efficient than the AMD chipsets (that support AM2 CPU's)? I think both support ECC ram but I'm not certain.
I have read that AMD chipsets are not very good with Linux. Can anyone confirm this?
I am assuming that the most recent chipsets will be the most power efficient.

A bit old thread already but to answer your question, I've been researching this for a home server also and apparently the most efficient chipset is the GF7025/7050 based ones. The absolute lowest consumption board seems to be the out of production Asrock AliveNF7G-HDReady (maybe the other variants of that board are the closest ones). There are other boards that get very close, ~1W, so the difference between those and that specific ASRock model may well be a measurement error I guess. In any case the chipset has fairly consistently given the lowest numbers when compared to other AM2 chipsets.
There's lots of discussion about this on the german forum Meisterkuehler, I resorted to Google Translate to understand it as I don't speak german.

Now that I can link and found some references, here's a thread with some consumption information on various boards grouped by chipset:
Stormverbrauchstest AM2 and AM2+ mainboards
The problem is of course that most of those boards are out of production, but seems like for example the ASRock N68PV-GS gets similar numbers. It's a pretty stripped down board though.
Of the newer chipsets the 790GX seems to be a fairly low consumption one even if it doesn't match gf7050/630a. There was a thread about someone's quad-core Phenom II at 25W idle, part 2 project that I stumbled upon and the MSI recommended in that first link waas a 790GX too I think.

my current Athlon II x2 rig comsumes 29-30w idle:

Maybe I could strip even few more watt going to SSD and quitting the DVD-RW, but for me a 30w -ish consumption is fine.
Doing "average" tasks (office + surfing+ play music) my pc consumes around 31-34 watts, and that's is 90% of time.

Also check out matt_garman's excellent thread: Biostar A760G-M2+ - 30W barrier broken.
Question: How are you using Ubuntu with ZFS? Via fuse? That's a sub-optimal implementation. Ideally, I think you should strive for in-kernel ZFS implementation. I believe this restricts you to solaris and BSD at the moment. For a simple file server, FreeBSD supports ZFS in-kernel, but I believe it's an older ZFS rev.
