ASUS ROG Crosshair VI Hero Review


ASUS ROG Crosshair VI Hero Testing:

Testing this new platform will involve running it through OCC's test suite of benchmarks, which includes both synthetic benchmarks and real-world applications, to see how each of these products perform. The gaming tests will also consist of both synthetic benchmarks and actual gameplay, in which we can see if similarly prepared setups offer any performance advantages. The system will receive a fully updated, fresh install of Windows 10 Professional 64-bit edition, in addition to the latest drivers for each board and NVIDIA drivers for the NVIDIA GTX 1080 Founders Edition. In the past, we had locked the clock speed on the processor to eliminate any easily controlled variables due to processor speed. However, there is a difference in how each manufacturer handles the CPU default and boost speeds, creating an opportunity for one board to deliver a higher level of performance. This variable is a point of difference between boards. The majority of users will run the stock settings, making this point a valid concern, so we are changing up the test methods to capture this difference.

Overclocked settings:


As I saw when I first looked at the RYZEN 7 1800X, the overall maximum core clock speed on this architecture is currently in the 4.0GHz to 4.2GHz range for most users. Some chips do a little better, some a little worse. When I tested this one originally on the Gigabyte AX370-Gaming 5 AORUS, getting the processor up to and over 4.1GHz was pretty much an impossible task. That was even when cranking up the core voltage to levels that were significantly higher than the H110i cooling solution could handle. While testing this same CPU on another board, anything over 4100MHz applied in the BIOS would result in an instant crash.

We see pretty much the same story here with the Crosshair VI Hero. So, nothing new that is going to hurt us. ASUS' own 5-Way optimization tools work well on this processor, board and memory combo. The 4100MHz hard limit when tuning manually was exceeded by 50MHz and was actually somewhat stable by comparison. However, it took 1.57 volts applied to get there. It would run, but not for the long term. Going back into the BIOS and re-tuning the core voltage and core clock multiplier I ended up at 4080MHz that was stable through all of my testing.

Much like I saw on previous boards, there are multiple pathways to overclocking a RYZEN processor on the ASUS Crosshair VI Hero. Manually tuning the parameters in the UEFI BIOS works well and will easily get you to all the processor can handle for everyday use. What I was able to get was a stable 4090MHz using an applied 1.45v in the BIOS with the LLC set to the most aggressive point.

Using AMD's RYZEN Master overclocking tool is an easy-to-use piece of software and takes just hitting the profile you want to try and applying the change. It works, but does not tune the whole system. It is easy to go well above your hardware's capabilities, so adjust this tool carefully. You just have to pick how you want to run overclocked and build the cooling to suit your need. An AIO does well, as long as you do not crank on the current too hard.



Maximum Core Clock Speed:

Each CPU has been tested for stability at the listed overclocked speeds. These clock speeds will represent the level of performance shown by the overclocked scores in the testing.
