Overclocking and Conclusion


To give a feel for the overclocking performance potential of the Strix X99 Gaming motherboard, we attempted to push it to known CPU-supported performance parameters with minimal tweaking. The board seemed very finicky when attempting to push the base clock speed, but we were able to get the board stable with a base clock speed of 100Mhz speed, a 4.3GHz CPU speed, a 4.0GHz ring bus speed, and a 3200MHz memory speed. All overclocking sessions remained stable for over 4hrs. System stability was tested running the AIDA64 stability test in conjunction with EVGA's OC Scanner X graphical benchmark running at 1280×1024 resolution and 8x MSAA in stress test mode. Note that 16GB (4 x 4GB) of Corsair Vengeance LPX DDR4-3200 memory modules were used for the overclocking tests.

100MHz Base Clock Stats with 3200MHz Memory

Note that this is is meant only as a quick preview of the board's performance potential. With more time to tweak the settings to a greater extent, pushing to a higher base clock and ring bus speed may have been achievable, in addition to an overnight stability run without issue.


The Strix X99 Gaming motherboard performs well as stock speeds with no performance surprises seen in any of the benchmarks nor with in any of the subsystem tests. Overclocking the board seemed to be a bit trickier, but may have to do more with board enhancements specific to the Broadwell line of processors, rather than a problem with the board itself.


As of August 29, the ASUS Strix X99 Gaming motherboard was available at Amazon.com for $334.99 with Prime shipping. The board was also available from Newegg.com for $334.99 and from B&H for $334.99.


The Strix X99 Gaming motherboard introduces an interesting synergy product for ASUS – one that seeks to combine the performance of a ROG X99-based board with the gamer-centric featured inherent to the Strix product line. The board features a gamer-appealing all black PCB and heat sinks with RGB LEDs strategically placed to maximize the board’s aesthetic. Additonally, the integrated 12V RGB LED port allows for sync’ing case LED strips with the board illumination settings. The board performs very well at stock speeds, but was a bit tricky to dial-in for overlocking purposes. With its ATX form factor, the board offers excellent compatibility with a wide variety of cases. Further, ASUS designed its layout in an open and uncluttered fashion.
