Power Consumption

We measured "system" power consumption at the wall outlet using a Watts Up Pro power meter. We do not include the power numbers for a monitor or external speakers; however, we do install a set of headphones to the audio out jack. We also turn on all peripherals in the BIOS along with enabling all power saving features. Power consumption was measured at idle after a 15 minute period and under a load while measuring the average power consumption of the Ambush level in Crysis Warhead. Windows Vista is set to balanced performance mode and the prefetch folder is cleared for each test. Our two tests consist of the standard BIOS power savings mode and a second test using the energy saving applications provided by each supplier. Today the latter consists of the MSI, ASUS, and Gigabyte boards.

Idle Power Consumption

Load Power Consumption

At idle with the BIOS only setup, the Intel DX58SO has the lowest power usage and is followed by the MSI, Gigabyte, ASUS, and EVGA boards. The load numbers favor the Gigabyte board with the EVGA once again utilizing the most power. Our power numbers have fluctuated greatly as the BIOS designs have improved for each board. EVGA just delivered a new BIOS that we are testing now that addresses S3 resume problems and should improve power consumption numbers also. The latest Gigabyte BIOS also provided a significant decrease in idle power consumption as it originally matched the EVGA board.


Power Savings due to Custom Power Design


Power Savings due to Custom Power Design

The MSI Greenpower system provides the greatest power savings compared to the ASUS EPU-6 and Gigabyte DES designs at present. The MSI board has an idle power reduction of 9W with the ASUS and Gigabyte boards dropping 5W. We noticed that even under gaming, each design managed to save a few watts during our load testing. We utilized a beta version of Gigabyte's DES software that has preliminary support for the X58. All three suppliers indicated we should see slightly better results in the next round of BIOS and software updates.

    i'm tired of being a free beta tester for these "top" tier manufacturers (remembering my E7205 days). If I'm going to spend $300.+ on a motherboard, I expect it to work AS ADVERTISED. I used to upgrade every year but for the past couple, I've been hesitant to do so. I don't want to fork over my hard earned cash (particularly in this economy)for a new rig only to spend hours on the phone with some tech support guy that dosen't know half of what I do ( let's start on page ten ok?)and wait weeks for a bios that corrects the problem. My Opty rig has been incredibly stable while producing a 50% o/c (thanks eVGA)but is getting long in the tooth. I run SLI and have been waiting on an Intel chipset that supports it. I'm going back to intel and the i7 920...maybe. I'm going to wait a couple of months tho. Bleeding edge, spending that kind of coin, and the hassle of working out the bugs, after fifteen years it's not worth it to me.
    Sorry for the rant. Jmh $.02.
    btw, great article.

    There isn't one board manufacturer thatdoesn't have a bunch of people complaining in the forums all over the internet. Anand's opening explains why.

    I hate upgrading bios expecting better stability or performance and getting more problems or no fixes.

    Gary, i think it is time to have some kinda of database that covers all boards and their known issues going back 2 years or to the 3 series boards. if the flag ship board has a problem then by extension lower end boards have that problem. if they didn't care to make their product the best then that is their problem. GIVE THEM BAD REVIEWS so that they get on the ball.
    I never knew Anandtech went back and forward with the board makers as if you're beta testers.

    We need to do something to make things better

    I'd argue that it is entirely possible for the flagship product to have problems that lower-end products do not. Expensive X58 is the only option for now for i7 processors, but look back at LGA775. I wouldn't be at all surprised if some stability compromises were made on X38/X48 boards in pursuit of higher SuperPI numbers, while those same compromises are probably not present in the mainstream P35/P45 boards of the same age. Motherboards are one area where I can see going with a mid-level (~$90-130 for LGA775) product might give a better result for the majority of users than jumping to the high end would.

    Beside the GHz, and MB/s would be good to have a chart/list, which shows the problems of the parts, and aggregated charts to show problems belongs to the same company, ... or SEARCHABLE DATABASE about errors related to products / companies and solutions

    "Our plan is to cycle through each manufacturer so we are not singling out any one supplier but we are going to be brutally honest in our assessments in these particular focus reviews." (the quote button never works for me in Firefox. Plz fix)

    Awesome. At least someone is. I think a "two strikes before we post" policy is fair.

    After reading the first page of this article “Intel X58 Motherboard Roundup - What does $300 Get You?”, I started reading all the blogs. At first I agreed 100% with Anand’s comments, and wanted to jump on the band wagon like everyone else, but then I read some of the response. Realistically, review sites can’t use the boards under test with ALL the different software/hardware configurations consumers will, and they cannot postpone a review until all the BIOS and operating bugs are fixed…they would be releasing a review a year (or more) after the next generation hardware has already hit the market. People don’t visit these review sites to see how good a DDR2 system is compared to a DDR system, they come to these sites to read about the future, to get the “inside scoop” as to what the manufacturers are thinking up next, and to see the new features of hardware out there today because they are thinking of upgrading right now. To read about overclocking and performance comparisons is really just a bonus for the overwhelming majority. Most people just jump to the conclusion page to see if the reviewer recommends the product or not. We’ve all done it.

    Review sites need the merchandise to review and the funds to stay afloat, so upsetting certain manufacturers is not in their best interest. They can get away with critiques, questions, “less than expected” reviews, and some (very little) criticisms, but if they were to only give bad reviews every time, manufacturers would stop sending them products to review. And if you think that is a good thing, “they’ll just purchase the final release like the rest of us and provide a balanced review”, think again. If a review site did that, 1) it would have to advertise like crazy to maintain its purchasing ability, 2) not be able to provide future analysis, 3) and not provide the consumer anything more than what “free” chat rooms/manufacturer message boards give you.

    I agree there needs to be an industry-wide change; a change in R&D, change in QC, and a change in review process and reporting, BUT the real change has to come from the consumer. We the purchasers of their merchandise have to take a stand, bite the antiquated hardware bullet, and wait to buy until all the bugs are fixed (at least to a reasonable state). As long as we continue to want to be “the first” or “the fastest”, manufacturers will continue to scramble to be first on the market with crap that can or cannot be fixed later on.

    Don’t jump down the throats of review sites like AnandTech; instead tell them what YOU want to read about. Give these sites constructive criticism, and suggestions to better themselves like Christoph, Gary, Anand, and all the other reviewers here give the manufacturers. The old “if you don’t have anything better to say, then don’t say anything at all” thing.

    Personally, I would love to have AnandTech continue to review the next best thing before it hits the market just to see what the manufacturers are planning and whether or not the reviewer thinks upgrading will be worth it, BUT I also want them to then purchase that same item over-the-counter for a “final look” review, and then tell it like it is. Of course that can’t be done with all items initially reviewed (too time consuming), but the items that bloggers have shown the most interest in.

    First, kudos for reqiring reliability. I've now bought the ASUS board. I won't overclock because I know what gate stress does to CMOS electronics (I slowly destroyed a chip I was testing at an elevated voltage. 18 hours is not enough time to run a $300 CPU). I use my computer to get work done and view overclockability as an indication of robustness in the board's engineering. If it's not - I need to know this. Thank you Gary and Anand - beleive me, $100 extra is a small price to pay for a motherboard that will not waste days of my time trying to get it to work.

    Second, a notice to those of you who are going to buy the ASUS board. They put the "Crash Free BIOS utility" and the driver installation utility on the same CD. Since installing all the drivers takes 3 restarts, imagine my surprise when installing the ethernet drivers did several surprise BIOS flashes (I didn't even know what was happening at first and I reset the system a few times during the process. To ASUS's credit, the board recovered).

    If I pay $300+ dollars for a board, I expect them to pay the extra 5 cents and include a second CD. When you go through your three restarts, make sure you remove the disk every time then put it back in once the OS starts up. Shame on you ASUS for the oversight.

    That said, everything is working well now. I hope I didn't buy a product from the company who thought it was only OK for 3 GB to run reliably as I'm running 6 GB now and will go up at some time in the future since I run math sims.

    cheers,
    --Steve Z.

    Reading the sections on each board, I think the ASUS was the only board which fully worked, out of the box, with 12GB of RAM. This strongly implies they were *not* the 3GB company.

    It's hinted the Gigabyte had some undescribed issues with 12GB and older BIOS's, and it's stated that the EVGA also had undescribed issues with 12GB (no indication whether those issues were at stock speeds or when overclocking). The MSI still has issues overclocking 12GB or RAM - nothing said about whether it worked at stock speed out of the box.
  • LeeKay - Saturday, December 6, 2008 - link

    I bought the GA-EX58-Extreme as I posted in the forums the quality of the board is the best I have seen but support wise and bios wise this board sucks worse than any board I have had. For a motherboard to have issues when I use 12GB is beyond me. I want to use this pc for everything from online banking thru gaming for the wife my son and me and to do video editing. Right now I can just run Need for speed undercover at any resonable clock speed without it crashing. Thats as of F4j. And I still can not let my board go to sleep with S3 enabled nor can I expect my Data drives running on the hardware raid controller to recover in S3 mode nore can I run my pc with any of the energy saving options in the bios. Oh and I cannot run my memory at 12gb and at 1600Mhz just noway in hell it will be stable. I have to run it at 1333mhz. I cant run SLI and have my X-FI PCI sound card in either PCI slot and have the pc boot into windows. It just blue screens with the latest Bios. (I am running 2 280GTX with single slot active cooling).

    The good note is to run at 4.13ghz I am running 1.425v without loadline correction. its stable and with the above taken into account far better tha the past issues.

    Your comments are extremely well thought out and relevant.
    The idea that $300(!) motherboards don't work reliably upon release
    is beyond ridiculous.
    I think your plan to write an as-is review initially in a great idea.
    This will give early buyers a true heads-up on what they're getting.
    And then later, you can perform your invaluable beta feedback service to the manufacturers and your readers.
    Hopefully, this policy will cause improvements on the QC end.
    Thanks again for being so on top of it!
