We utilized memory kits from Corsair and G.Skill to verify memory compatibility on our test boards. Our OS and primary applications are loaded on the OCZ Vertex 120GB SSD drive and our games operate off the WD Caviar Black 1TB drive. We did a clean install of the OS and applications for each motherboard. We used Intel's stock cooler for the stock comparison testing, while water-cooling via the superlative Heat Killer 3.0 water block was utilized for overclocking. For graphics duty, MSI’s GTX 275 Lighting GPU was used to provide performance comparisons between boards during gaming benchmarks.

For our test results we set up each board as closely as possible in regards to memory timings. Otherwise all other settings are left on auto. The P55 utilized 8GB of memory where possible, while the X58 platform contained 6GB. The P55 and X58 DDR3 timings were set to 7-7-7-20 1T at DDR3-1600 for the i7-920 and i7-870 processors at both stock and overclocked CPU settings.

We used DDR3-1333 6-6-6-18 1T timings for the i5-750 stock setup for all system benchmarks (non-gaming tests) as DDR3-1600 is not natively supported at a stock BCLK setting of 133. For our Clarkdale i5 661 and i3 540 CPU’s, we used 7-7-7-20 1N timings at DDR3-1333MHz with 8GB of memory (4GB on the Mini-ITX boards).

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. These figures measure only the CPU, motherboard and memory DC power draw and exclude any other peripherals, such as cooling fans and hard drives etc. Actual AC power consumption for the motherboard will be anywhere from 15~40% higher than these figures depending upon the efficiency of your power supply.

Motherboard Power Consumption - Idle Power - i5 661 CPU - IGP

Motherboard Power Consumption - OCCT Small FFT - i5 661 CPU

Motherboard Power Consumption - HD Video Playback - i5 661 CPU

There's no reason to choose one board over the other based upon the differences we're seeing here - a three watt difference under full-load is not worth worrying about.

    The CPU multiplier ratio control option should either be removed altogether, or it should be made to work. In its current state the option is useless, serving only to create non-POST situations


    Like the subject line says. I have this CRAAAAAZY idea. How about instead of trying to OVERCLOCK the dammed board. How about you try and do something insane such as use the board for it intended purpose, and *maybe* underclock / undervolt the board ?

    But Gee, I guess that would make too much sense eh ? Just because you can try and do something. Does not mean that you *should* do it.

    I had flashes of those ideas too. They were swiftly tempered when i found that the BIOS has no undervolt options, a minimum BCLK of 133 and broken control of CPU multiplier ratios.
    With regards to underclocking and undervolting; power gating on C-States is pretty good, so there's not much if any saving to be had in very light load situations when you've got no effective multiplier control and a minimum BCLK of 133. Best thing you can do with the board in its current state if you want to encourage ultra-low power consumption and low levels of heat is to use Windows power options to set a high load threshold for SpeedStep ramping (low multiplier VID is programmed around 0.85V on the Clarkdale CPUs).

    Hope that helps.

    I have this crazy idea too, that this is the first time I've seriously considered an ITX board because ECS was cool enough to allow real overclocking. I also find it pretty great that they do allow you to overspec the power. I wish there was some way to send a "bravery" award to the BIOS engineer(s) who slipped that through.

    So either heatsink like mad and hope you can stave off burning the power section with your 4.5Ghz i7 - or admit the fact that burning up 2 of these boards is STILL CHEAPER than most other ITX boards that don't even have this much overclocking flex.

    Wow, really ECS maybe IS getting back to it's overclocking roots. ECS boards were common overvolt-mod fodder because of this. Which is a good thing - just to clarify that I'm NOT slamming ECS.

    Since otherwise it's just time to get a Dell.

    At least for me as I am about to build a home server box.

    Boards like this are perfect. Stick a RAID card in the PCI-Ex16 slot then add 4x2TB HD and works just as I want.

    Now all I have to understand is how to set Linux as my primary domain controller for a network of Windows box (window 7, vista and XP pro) and I will be rocking

    Just a quick one Raja.

    Would you say this is a better board than the Zotac H55 mini ITX, especially when it comes to overclocking and stability? Also, do you know if you can change the IGP clock ratio on the Zotac H55 board?

    Many thanks in advance.
  • Rajinder Gill - Friday, May 7, 2010 - link

    Hi,

    Assuming ECS don't back-track, the H55H-I is probably a tad better for overclocking Clarkdale processors. Zotac's board is limited to using stock VTT.

    If you can look past the overclocking/underclocking stuff, the only reason I can see to buy the Zotac relates to the additional USB ports on the rear I/O panel (10) and the inclusion of WiFi. Otherwise, it's ECS all the way.

    What does it take to switch between a graphics card and the IGP? If you have a discrete card in, but want to use the IGP (for power savings), can you reboot and change something easily in the BIOS? With monitors coming with more than one DVI or HDMI input, this would be handy.

    Or is it the case, that as long as the discrete card is detected, it will always be on, no matter what?
  • Rajinder Gill - Friday, May 7, 2010 - link

    Hi,

    As soon as you plug a discrete card into the PEG slot, the IGP switches off - and there's now way to activate it again unless you remove the discrete card. BIOS does not offer any option for switch-over unfortunately. I don't have a discrete PCIe soundcard here, but suspect that would have a similar effect on this board too (I should have a soundcard here soon I can test this).

    regards

    Really? That would be a massive mistake if plugging in ANY PCIe device kills the onboard video, a discrete GPU isn't the only thing a user might want in that slot.
