M5A99X EVO R2.0 AMD 990X (Socket AM3+) DDR3 ATX Motherboard

The M5A99X EVO series offers unsurpassed compatibility with new AMD AM3+ socket CPUs, whilst also being backwards compatible with the previous generation AM3 CPU. The M5A/99 core series is equipped with DIP2, which features DIGI+ VRM technology in addition to the TPU and EPU. DIGI+ VRM power delivery allows users to precisely adjust and control power settings digitally for precise power control and flexible tuning of their system, perfectly serving the AM3+ CPU specification’s power demand. Digital control differs from analogue controls by eliminating digital to analogue conversion lag, which helps to improve overclocking capabilities. This means precise power flow adjustment and management as well as easy and flexible tuning including extra DRAM power control for the AMD platform. It is the most precise power delivery available, providing the best-in-class in power efficiency, performance and stability while also helping to maximize the overall overclocking potential.

Also included on the M5A99X EVO is the intuitive UEFI BIOS menu interface. UEFI BIOS allows a user to control and adjust their BIOS settings through the use of a mouse-enabled interface for more user-friendly navigation. The built-in EZ Mode option also provides a drag-and-drop boot priority option, for easier management of boot devices.

Excellent MotherBoard

This is the first Time I have had an Asus motherboard. This was inside my pre=build system from overclockers and I am very impressed with the features this board has and the available functions inside the bios.

I have only had this for 1 week now so I cannot advise what its like for reliability, but the over clocking potential is amazing. I would defiantly recommend this board,


Good board but Ram slots failed after a

Ive got this board in a pre-installed custom pc, its been running my Fx 8120 at 4Ghz happily just over a year, but only recently have i been trying to get more ram installed, but it wasn't seeing the 32Gb i had installed(manufactures recommended), only two of the slots are working. Currently trying to get an RMA from Asus, slow progress.

Loud fans until silent mode is active
