Asus M4A77D compatibility review

The Asus M4A77D uses the AMD Socket AM2+ CPU socket. Any compatible AMD CPU will have the same socket entry. It uses the aging DDR2 memory type, with maximum speeds of up to 1066 MHz, and 4 DDR2 slots allowing for a maximum total of 16 GB RAM. DDR2 memory is exceptionally out of date, and considering how cheap DDR3 RAM is, using a motherboard with only DDR2 compatibility in a modern system build would be a very bad idea.

Conforming to the ATX standard, the Asus M4A77D should fit into the majority of cases. ATX is the most common form factor, and as such has a high degree of compatibility with other components while providing a decent number of slots to widen your expansion options.

The Asus M4A77D has 6 SATA 2.0 hard drive slots. These allow for data speeds of up to 3GB/s. SATA 2.0 is a very common standard, and despite the emergence of SATA 3.0 - whose potential is difficult to reach currently - SATA 2.0 remains a viable option.

The Asus M4A77D does not support onboard graphics. Any system build that uses this motherboard therefore requires a separate graphics card, or a processor that has a GPU on the same die, such as AMD APU processors. There are 1 PCIe x16 slots on this motherboard. This means it is perfectly capable of accommodating the latest graphics cards, although it is important to try and use a graphics card with the same graphics card interface of Not sure, as anything below will not reach the motherboard's potential, and anything above will have its performance slashed to the bandwidth maximum of the Asus M4A77D's Not sure. The Asus M4A77D does not support multiple graphics cards via Nvidia SLI or AMD Crossfire.

The Asus M4A77D has 8 USB 2.0 slots but no USB 3.0 slots. While USB 3.0 slots are so far by no means necessary, and with a plethora of USB 2.0 peripherals to choose from, the USB functionality on this motherboard should be fine. If planning on building a new system, a motherboard with USB 3.0 is likely to have a longer life cycle, however.
