Overclocking and Conclusion


To give a feel for the overclocking performance potential of the ROG Maximus XI Formula motherboard, we attempted to push it to known CPU-supported performance parameters with minimal tweaking. Note that for this test, the EK Crosschill VRM cooler was air cooler only. At the stock base clock speed of 100Mhz, we pushed the CPU to 5.0GHz with a 4.7GHz ring bus and 4000MHz memory speeds. This was done at a 1.275V CPU voltage, a 1.20V CPU System Agent Voltage, a 1.05V CPU VCCIO Voltage, and a 1.375V memory voltage with all other values left at default settings. 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 8GB (2 x 4GB) of Corsair Dominator Platinum DDR4-4000 memory modules were used for the overclocking tests.

Liquid-Cooled VRM Overclocking

Using the same voltage settings, components, testing methods stated above, we we able to eek out a bit more performance from the board by interfacing the EK Crosschill cooler with the DIY cooling loop used for the processor. We we able to push the ring bus speed up to 4.9GHz using the same voltage settings used above in tandem with a 100Mhz base clock, a 5.0GHz CPU speed, and a 4000MHz memory speed by water cooling the VRMs. Unfortunately, the ROG Maximus XI Formula does not provide integrated temperature sensors for the VRMs or the coolers, but the 200MHz performance gain for the ring bus illustrates the gains from liquid cooling the VRMs sufficiently.

As of February 25, the ASUS ROG Maximus XI Formula motherboard was available at Amazon.com for $418.39 with Prime shipping. The board was also available from Newegg.com for the same $418.39 price.


The ROG Maximus XI Formula board is a sample of ASUS at their best. The board is almost perfect design-wise and aesthetically, engineered for superior performance as well as to easily integrate into almost any gamer build. The old adage "you get what you pay for" applies here. The price of the ROG Maximus XI Formula is bordering on unapproachable for all but the top-tier enthusiasts, but ASUS did integrate several features to justify the price – full board armor, the custom designed EK Crosschill copper VRM cooling block, integrated LiveDash OLED display panel, and the Aquantia AQC111C 5G LAN port and Intel 802.11AC 2.2 WiFi ports integrated into the rear panel. ASUS also took an innovative approach to the integrated RGB LEDs, embedding them into the armored panels covering the board's surface and giving the board a very futuristic Matrix-like quality. The board's performance speaks for itself with high levels in both stock and overclocked configurations.
