I gave this 4 stars because the connectors did not really fit with my case, but that just might be my case. The motherboard was under clocking my CPU and I went through much trouble fixing this.

Very cheap board, maybe look for something else. On an aging socket like this, I absolutely recommend the A88 chipset for overclocking.

Also, watch out! The cooler screws are located in an orientation that will force most tower coolers (I've used both the Hyper T2 and Noctua NF-U9B) to push air vertically (from the back of the GPU towards the top of the case) rather than horizontally (from the front to the back of the case) which may lead to worsened airflow.

BIOS works fine, but the drivers and software are pretty terrible. When I first started, it properly detected by front and back panel audio jacks as different devices with their own volume settings. Since then, something has changed and now it always merges them together, which means calibrating the volume to use headphones comfortably is a nightmare.

USB 3.0 connector is very difficult to remove during maintenance, and lead me to accidentally tear off the plastic housing around the pins. Nothing was damaged, but annoying none-the-less.

UPDATE I'm about ten months into ownership now, and I believe this thing might be failing. CPU is reaching 75 C at idle. I'm still investigating this, however, as my PSU has also failed.

A decently priced mobo, lots of SATA ports for my purposes, and a surprising maximum memory amount. My only issue (a big one, too) is that it randomly underclocks my CPU. Otherwise, I probably would've given it a 4 or 5.
