Gigabyte 990FX-Gaming AM3+ Motherboard Review

We will be outlining the Gigabyte 990FX-Gaming motherboard’s performance with an AMD FX 8370 CPU, 16GB of DDR3 memory, and a GTX 980 Ti graphics card.


Unfortunately we do not have access to comparison data from other AM3+ motherboards. As such, we will highlight the performance gains available by using the Gigabyte 990FX-Gaming motherboard to overclock the FX 8370 CPU.

Despite the FX 8370 supporting a maximum Turbo Clock speed of 4.3GHz, Gigabyte’s motherboard kept the chip at 4.1GHz using a 20.5x multiplier. This is likely to be a bug related to the motherboard’s early BIOS revision, and will have an impact on performance.

The 2400MHz memory profile was loaded from our Corsair Vengeance Pro DDR3, however the board automatically set the kit to 2133MHz instead due to its 10.67x maximum memory multiplier.
