ASRock Fatal1ty X99 Professional Motherboard Review


We will outline the performance increases that can be obtained from using the ASRock Fatal1ty X99 Professional motherboard to overclock our system. Our overclocked processor frequency was 4.4GHz and memory speed was 2666MHz.

As a performance comparison, we have included the overclocked results from four other X99 motherboards. The maximum overclocked configuration achieved with each board was a 4.4GHz processor frequency.

OC 3DMark

OC cinebench

OC bioshock

ASRock's Fatal1ty X99 Professional fairs well in 3DMark when overclocked, and the board puts in a decent Cinebench score. Those performance gains do not extend to Bioshock Infinite, however; the frame rate actually dropped by around 3-4 FPS when the system was overclocked.

It's not the first time we have seen this happen to a motherboard, so after confirmation from numerous re-tests, I began to dig into the issue and find its cause. The problem seems to derive from manually applying an all-core CPU multiplier. Even manually requesting an all-core multiplier of 35x (the standard enhanced turbo level) would cause the frame rates to drop in Bioshock Infinite. This is an odd issue and one that needs further attention.

It is worth pointing out that Bioshock Infinite was the only game affected; neither Tomb Raider nor Metro: Last Light suffered FPS drops when the system was overclocked. This potentially points a finger towards the Bioshock Infinite benchmark itself.

  3. You guys make some weird choices. You have trouble using the 2666MMhz g.skill memory and opted to use memory from Corsair, but later in the review you say that the 3000Mhz G.Skill memory was performing fine. So why not do the main tests with the 3000Mhz memory instead of 2666Mhz memory from another manufacturer. It seems to me that the 3000Mhz and 2666Mhz memory modules of G.Skill are closer to each other than 2666Mhz memory from different manufacturers..

  4. so what’s better for gaming the z170 or the x99
