Gigabyte X99-SLI Motherboard Review – Welcoming & Budget Friendly!


The following benchmarks are done by using the Intel SATA port.


The toughest benchmark available for solid state drives is AS SSD as it relies solely on incompressible data samples when testing performance.  For the most part, AS SSD tests can be considered the ‘worst case scenario’ in obtaining data transfer speeds and many enthusiasts like AS SSD for their needs.

ATTO Disk Benchmark is perhaps one of the oldest benchmarks going and is definitely the main staple for manufacturer performance specifications. ATTO uses RAW or compressible data and, for our benchmarks, we use a set length of 256mb and test both the read and write performance of various transfer sizes ranging from 0.5 to 64MB. Manufacturers prefer this method of testing as it deals with raw (compressible) data rather than random (includes incompressible data) which, although more realistic, results in lower performance results.

Crystal Disk Benchmark is used to measure read and write performance through sampling of random data which is, for the most part, incompressible. Performance is virtually identical, regardless of data sample so we have included only that using random data samples. Further, we are using the newest release of CDM where the queue depth, and even thread count, can be set.

For our CPU benchmarks we run our CPU at the stock clock as well as overclocked to the highest stable speed we would expect with the motherboard, which is 4.5GHz. In our graphs we will show performance difference between stock clocks and overclocks.


For bench-marking memory bandwidth we use AIDA64’s ‘Cache and Memory Benchmark’ and compare the differences between stock and overclocked CPU.

For bench-marking memory latency we use AIDA64’s ‘Cache and Memory Benchmark’ and again we compare stock and overclocked CPU results.

Today we will have a look at the Gigabyte X99-SLI motherboard and its features, as well as putting it through some benchmarks to see how the board performs. At first glance we were expecting this board to perform nicely on air and water, which as you will see for a budget board it performs quite well even overclocked. Gigabyte is well known for its fleets of motherboards in all series to meet the needs of the end users, from your average home user, gamer, overclocker and extreme overclocker. The Gigabyte X99-SLI caters for your average user and gamer, while overclocking rather…
