The gaming/performance figures tell a familiar story:

Gaming Performance - Dawn Of War II - Stock CPU Speed

Application Performance - WinRAR 3.90 x64 - CPU @ Stock

Power Consumption

Our power consumption testing utilizes the same batch of components under similar circumstances in a bid to monitor variances between idle and CPU load conditions. We install the vendor supplied power saving utilities on each board and enable power saving modes that don't involve any kind of underclocking or CPU core frequency modulation in order to run an apples to apples comparison.

ATX PSU switching losses are absent from our figures because we monitor power consumption directly at the DC rails of the PSU. Total system power consumption will vary depending upon the efficiency of your PSU.

DC Power Consumption - H.264 Video Playback

While AMD processors can’t keep up with Intel’s for power consumption, the M4A89GTD Pro turns in a respectable performance against ASUS’s ATX sized Intel equivalent P7H57D-V Evo. The X2 555 falters slightly in these tests due to a high stock VID of 1.35V. The soon to be released X4 910e operates at 2.6GHz with 4 cores with a 65w TDP hence the lower consumption numbers.

You can under-volt the X2 555 somewhat to reduce its power draw, although we found our sample was not capable of running at 3.2GHz at a VID lower than 1.25V. As a quick experiment, we overclocked the 910e to 3.2GHz whilst maintaining a 1.15V VID and it came through our benchmark suite without a problem - whilst pulling only a few extra watts of power. The X4 910e is definitely a superlative bin.

DPC Audio Latency

We’re often asked to include a DPC latency screenshot by audio enthusiasts, here’s what the M4A89GTD Pro manages:


Although we managed to hit target frequencies with all of our processors, the most exciting processor to overclock out of the bunch was the X2 555. Unlocked to 4 cores, we ended up with a stable 301 base clock; a shade over the 4GHz mark running 8GB of our Corsair Dominator GT’s @ CAS 6-7-6-20 1T DDR3-1604MHz:

For those that like to benchmark and chase numbers for fun, base clocks up to 390MHz are possible if you use Turbo-V to increase bus speed within Windows (POST maximum up appears to be limited around 370 MHz).

It’s a pretty good show from ASUS considering the Hyper modules are rather picky about operating parameters on this motherboard. Using more ‘realistic’ modules, expect to see 4GB maximums fall in the region of DDR3-1800~1900 MHz at CAS 8, while good 8GB kits should hit the DDR3-1800MHz mark on the 0402 BIOS.

    Should clarify - I do not add GPU PCIe power draw because that is a separate entity from board consumption really. It's drawn from ATX 12v on most boards so is easy for me to factor out.

    You might want to do a writeup on what exactly you are including, as I was wondering how the CPU, chipset, and GPU all totaled only 29W at idle. Reply

    In hindsight I should have - I'll be sure to do so in future.

    For a second there I though the sticker ontop of the USB3 ports were an additional 2 internal USB ports. I was thinking "oh cool, that's nifty, don't know what I'd use it for (wifi?) but it's still nifty." Then I saw a closer picture and realized it was just a sticker lol Reply

    The blue header with the yellow sticker by the SATA's must be a PATA 133 IDE connector. It doesn't appear on your spec sheet on page 3. Reply

    I thought all AMD motherboards had the cage to mount a cooler to around the CPU socket. I don't remember the CPUs coming with this, is it included but not mounted? Do some coolers not use it? Reply

    They still come with the cage, I uninstalled it to mount the Corsair H50 cooler. So yes, some coolers do not use AMD's mounting plate..

    WTF is up with the PCI-E switch card? They couldn't swing for automatic switching on a $150 motherboard? Reply

    I wish all the motherboard reviews were this detailed.. Good Job!

    Most don't have a bunch of "new" features to try out really but I really think you set a new standard by including all the BIOS screens and such.

    does anyone know if the heatpipe below the chipset heatsink directly touches the HD 4290 IGP core?
