Overclocking and Conclusion


To give a feel for the overclocking performance potential of the Rampage V Extreme motherboard, we attempted to push it to known CPU-supported performance parameters with minimal tweaking. We were able to get the board to boot into the OS with a base clock of 125MHz, the CPU running at 4.5GHz, and memory running at 2666MHz with the system remaining rock solid while running the stability testing for over 4 hours. 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 32GB (4 x 8GB) of Corsair Vengeance LPX DDR3-2666 memory modules were used for the overclocking tests.

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 ASUS Rampage V Extreme board performed well at stock settings and when overclocked when compared with the other Intel X99-based systems.


As of January 08, the ASUS Rampage V Extreme motherboard was available at Amazon.com for $474.99 with Prime shipping. The board was also available from Newegg.com for $474.99.


The ASUS Rampage V Extreme is a testament to the ASUS ROG line with design aesthetics and performance that mesh in an almost perfect synthesis. The board features a black and red color scheme, common to the ROG product line, with all integrated components and ports colored to mesh into the design aesthetics. ASUS also included an aluminum overlay over the rear panel and upper VRM heat sink, giving the board a more uniform look. The E-ATX form factor allowed ASUS to integrate an enormous amount of extra features into the board, making it one of the most feature-rich offerings among the Intel X99 boards from all manufacturers. Its performance is nothing to balk at with it easily meeting our expectations. This board should give you no issues no matter what you throw at it.

The one concern with the board was the design decisions with respect to the bandwidth sharing among the PCIe slots and other integrated device ports. The sharing between the fourth red PCIe x16 slot and the M.2 port limits the performance of a high end systems, forcing the PCIe x16 slot to x4 mode when using an M.2 SSD. This is not problematic when using the graphics card for PhysX style processing only, but could affect system performance when attempting to use the system in 3 or 4-card SLI or CrossFireX mode. The other sharing-related oddity is the design between the black PCIe x16 slot, the left-most USB 3.0 ports in the rear panel, the PCIe x1 slot, and the ASMedia-controlled SATA-Express slots. As designed, you can use the black PCIe x16 slot in full x4 mode by sacrificing use of the other shared ports (the left-most USB 3.0 ports in the rear panel, the PCIe x1 slot, and the ASMedia-controlled SATA-Express ports). Note that this type of device bandwidth sharing is not uncommon among higher-end solutions, but changes slightly board-to-board based on how the manufacturer designs the board to split the available bandwidth between integrated devices.
