Performance summary

App and Gaming Performance

We found that the H55-ITX performs comparably to the other H55/P55 motherboards on the market during system benchmarking.

Application Performance - WinRAR 3.90 x64

Gaming Performance - Dawn Of War II

Power Consumption

For our system power consumption tests we measure the watts being pulled out from the wall socket by the entire system. Keep in mind that power consumption at the wall can vary for a specific system based on the efficiency of the power supply being used. For these tests every power saving option in the BIOSes were turned on.

System Power Consumption - Idle Power

System Power Consumption - Load Power

The Zotac H55-ITX put down some of the lowest idle power consumption numbers that I have ever recorded on a desktop. System consumption under 100% CPU load was very mild as well. Numbers this low would make the H55-ITX ideal for a system that is rarely shutdown, like a HTPC.

Audio Latency

During our battery of tests we also measure DPC latency. This will be of particular interest to the audiophiles of the world.


While testing the H55-ITX we decided to take a different turn for the overclocking segment. Instead of pushing the board to its limits in order to find its maximum frequencies we chose to find the perfect balance between speed and voltage. The fact that the VRM for CPU Vcore is very restricted and that the BIOS offered no adjustment for CPU VTT voltage helped point us in this direction.

To reach our final overclock on our i3 530 I simply raised the Bclock to 150, lowered the Vcore to the default, 1.20V, minus .025V and adjusted the Vdimm to 1.65V. 1.175V was the lowest Vcore we could use to maintain a 150 Bclock. All other available voltages were untouched. For system memory the timings were manually set to 9-9-9-24-72 and the frequency was set at 1500MHz. On a side note, I ran this system in a Silverstone SG06 and using the factory Intel heatsink core temperatures rarely got above 50 degrees Celsius.

We chose not to overclock the i7 860 to avoid any risk to the ZOTAC motherboards power circuitry. The H55-ITX simply wasn't designed to power a heavily overclocked quad core.

    Hi Patrick,

    Sorry about that, we'll get it fixed asap..

    Anandtech admins, you have some adbanner that irregularly appears on the site that uses javascript I believe and forcibly forwards users to "http: // / index.html" (spaces inserted to prevent people from ending up there inadvertently). It just happened to me when trying to access this motherboard review. It also happened to me once on the Anandtech forum...

    Not sure what, if anything, you can do about this. Just wanted to mention it.

    I've talked to our ad people and they've pulled a ton of stuff. Please let us know if any of you guys are still getting redirected. Reply

    Now that's service. How does that happen in the first place though? :( Reply

    ..and how many people have been infected by this?

  • Duwelon - Sunday, February 28, 2010 - link

    This has been happening to me too on anandtech only (as far as I recall). AVG catches it and prevents the transfer to the site listed above. I've run Malwarebytes free and done AVG scans, nada. I'm a pretty safe surfer too so I don't know where i would have gotten infected anyway. Reply

    Run HiJackThis and analyze your log to see if there are anything else Malwarebytes and AVG haven't found.
    Another is GMER and ComboFix.

    My wife was surfing (mostly on Facebook) last night and received this same message. I wrote down the address and it matches perfectly with the one you provided:


    She woke me up and said my laptop has a virus. I had her set the laptop aside until I had a chance to look at in the morning. I closed out the browser, and ran ccleaner, then ran anti-malware, and now running anti-virus scan (CA Antivirus Suite). So for nothing.

    I think it is a scam to get you to click on the exacutable which will then infect your computer. This has happend to us before and caused a great deal of grief.

    I plan on reporting the web site/event to the folks at Microsoft to see what they recommend, as well as my own ISP and provider of my Anti-Virus software (CA).

    The adds are definitly becoming more intrusive. I'm getting a lot of muscle adds and last week, I got my first popup on Anand, a popup that told me I was infected and to get an anti-virus.

    I'm mostly browsing at work, so I'm locked in IE 6, I would love if the adds could be about something I would actually click, not some muscle pills.

    That and I would be less inclined to copy/paste the text to notepad so it doesn't look like I'm browsing gay porn...

    Not that there is anything wrong with that.

    Again, it couldn't possibly be anything to do with Anandtech or Toms :)

    As I posted before, clean machine, fresh install, then updated behind a firewall, AV installed, no other machines on the connection

    Bam... re-direction.
