The ECS A55F-M4 (revision 1.0) FM1 AMD A55 is a low cost motherboard for the A Series Fusion APUs from AMD. Currently, it is the cheapest motherboard on Newegg. It is also the cheapest new FM1 motherboard offering an HDMI connection for the integrated APU graphics.
The good thing about this motherboard is that it has mouse support for the BIOS. Otherwise, this pseudo-UEFI BIOS looks just like any other regular BIOS. It offers overclocking options through their MIB III feature. This allows you to change CPU voltage, multiplier, and base clock. It allows you to change the DDR3 memory timings to fit your needs or memory modules. It is a great buy for the amount of performance you will be getting. For the most part, it works pretty well.
However, there are some issues with the ECS A55F-M4 that may be a problem to some users. The biggest problem that some people have is the motherboard appearing not to post. While the motherboard is actually posting, the built-in HDMI will sometimes forget to “initialize.” This means you would have to press the reset button multiple times to get the motherboard to post through HDMI. Sometimes unplugging and plugging up the HDMI cable again also works. However, this problem worsen in some situations. This event can be triggered by having the computer go to sleep or even hibernate. This can be a big problem when you have those power options enabled. Simply having the option to power down the monitor after idle can also cause this problem to start. There was a BIOS update to help the problem, but it simply seems to make the problem happen less often. This problem seems to happen only to the HDMI connection. If you are using the VGA connection then you can use the ECS A55F-M4 FM1 board just as easy as any other. Also, if you plan on using any type of external graphics card then you will also be in the clear for this particular problem. In that scenario, the external graphics card will be responsible for HDMI connections.
On a lesser note, another flaw with this motherboard is that there is no option to control the DDR3 RAM voltage. However, the voltage seems to increase a little when you turn up the DDR3 RAM frequency.
