to identify the source of the problem.
AMD StoreMI Technology
A powerful tool that combines the speed of your SSD with the capacity of your
hard disk into a single, fast, easy-to-manage drive, AMD StoreMI technology
combines these two types of storage into a single drive and automatically moves
the data you access the most to the SSD, so you get the best of both worlds.
XXL Aluminum Alloy Heatsink
Extra large aluminum alloy heat sinks that effectively take away heat from
the MOSFET and chipset so that your whole system may perform more stable.
Sapphire Black PCB
Pure black PCB appearance. The new Sapphire Black PCB represents rock-solid
quality and gives the motherboard a more mysterious touch.
High Density Glass Fabric PCB
High Density Glass Fabric PCB design that reduces the gaps between the PCB
layers to protect the motherboard against electrical shorts caused by
humidity.
2oz Copper PCB
Using only carefully selected copper materials for PCB layers, 2oz Copper PCB
delivers lower temperature and higher energy efficiency for
overclocking.
Full Spike Protection
