MSI elegantly designed the graphics and marketing material for the H55M-ED55's retail packaging. They also chose to focus on the marketing the board's OCGenie capabilities as well as the HDDBackup application and ATi CrossfireX support.
The back panel goes into more detail about the OCGenie and DrMOS features. It also discusses the board's overall specifications and the available I/O back panel ports. This is one of the few times that I actually like how the information on the back panel is layed out and the data is easy to read, which is important to consumers browsing for a new motherboard upgrade.
After unboxing the H55M-ED55 we got a better look at the layout of this micro ATX motherboard. MSI used a black PCB and blue highlights on parts of the memory and PCIe slots. They also added better cooling for the power components and chipset than other typical H55 boards in its class. Another classy addition is the power button with the OCGenie button that is typically reserved for MSI's most expensive motherboards.
The back of the PCB is nothing special and only includes a small aluminum backplate right behind the CPU socket.
The back I/O panel supports a variety of devices with six USB 2.0 ports, Gigabit LAN jack, HDMI, VGA, DVI, eSATA, and a combo keyboard/mouse PS/2 port. They also added 8.1 audio support and one optical audio out port. This bundle of I/O ports should give any HTPC user every option then needed aside from USB 3.0 and SATA 6GB/s device support.
The H55M-ED55 supports two PCIe x16 slots, one PCIe x1, and one PCI slot for legacy devices. These PCIe x16 slots can handle multi-GPU CrossfireX graphics cards, which should give users up to 2.7 times better performance over a single graphics card solution. NVIDIA graphics card users will need to look elsewhere because this board doesn't include SLI support.
MSI added three more USB 2.0 headers that support six USB 2.0 devices. The front panel headers can be connected through the JFP1 header. The JFP2 header is available for the speaker and power LED.
There are six available SATA 3GB/s ports courtesy of the included H55 chipset. But, RAID users should know that there is no RAID support with this chipset.
There are also four buttons for increasing and decreasing the CPU base clock in one megahertz increments, power button, and the OC Genie button that will automatically overclock the CPU. Mainstream users will find these extra overclocking buttons very useful to get a small, but stable overclock to help increase their system's overall performance.
This board supports up to 16GBs of dual channel DDR3-2133 (OC), 2000 (OC), 1600, 1333, and 1066MHz memory. Support for this type of memory is pretty rare in mainstream motherboards so users should take advantage of it as a key selling point for consumers.
The real estate around the CPU socket should be more than adequate to install a third-party air-cooled heatsink or even a water block for a custom water-cooling system. Users should also appreciate the extra heatpipe cooling for the power components on the H55M-ED55. There's also an extra three-pin power connector, which will come in handy with a case that uses multiple fans to exhaust heat from your PC case.
The "included extras" with this motherboard are a bit scarce hardware wise, but MSI makes up for it with custom applications that will expand the capabilities of this motherboard.
The back I/O plate is color coded and includes symbols for each port that are easily recognizable to average and experienced users. There are also two SATA cables and a molex-to-SATA power cable included.
These USB and power header adapters help make installation much easier so users can plug in multiple jumpers into one header adapter. ASUS was the first to do this several years ago, and now many other vendors are including them with their motherboards.
Lastly, MSI included a Winki user guide, HDDBackup user guide, overall motherboard user guide, and all the drivers and utilities supported by the H55M-ED55. Make sure to download the latest drivers and utilities at MSI's website instead of using the ones on this driver CD.
