Board Software
The first two utilities I made use of were eOC and eSF: the overclocking and SmartFan interfaces that ECS has been including with their boards for some time now. Both are just the same, with the eSF only offering control over the CPU fan header.
The final two utilities provided by ECS are "eBLU" and "eDLU": two utilities whose sole purpose is to keep your system up to date. "eBLU" is responsible for BIOS updates, while "eDLU" is used to download drivers and utility updates. I've used eDLU in the past, and it works quite well, making visiting the ECS website to search for up-to-date drivers and software completely unnecessary, but this time, it popped open a browser window to the ECS website where all the updates were listed. Oh well.
