ASUS Maximus VIII Gene Review


ASUS Maximus VIII Gene Testing:

Testing this new Motherboard from ASUS 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 7 Professional 64-bit edition, in addition to the latest drivers for each board and NVIDIA drivers for the NVIDIA GTX 770. 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 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. The only change from the as delivered BIOS defaults is to apply the X.M.P. profile for the installed DDR4 memory.

Overclocked settings:


Not surprisingly, the overclocking results of the Maximus VIII Gene are fairly close to the overclocking results seen on the Maximus VIII Hero I just looked at. For all intents and purposes the end results are the same and are different by only 15MHz. That's a pretty solid number when you get down to it from an M-ATX form factor motherboard. But that in a nutshell is how ASUS goes to market. Build from the ground up with good tech that gives the same performance and overclocking through the product stack with a little bit more on the signature ROG products. That aside, there are several different ways to overclock the ASUS ROG Maximus VIII Gene.

First, you get the ASUS 5-Way optimization tool that sets an aggressive yet manageable overclock while tuning the system based on parameters input by the end user. In this case my Core i7 6700K was capable of a 4.8GHz overclock that bumped the memory speed up to 2666MHz and left the cache ring ratio at 41. Voltage was tweaked up a bit to get the result, but was less than what I finally needed for my maximum manually tuned clock speed. At 4.8GHz, the auto tuning worked and delivered prime stable results. Pretty solid and about what I expected based on the results I reached on the Maximus VIII Hero. In ASUS' UEFI Crash Free BIOS, you can use the EZ Tuning utility on the EZ screen and the Advanced screen to tune the CPU performance outside of the 5-Way optimization tools parameters. Using this tool I was still able to hit 4.8GHz with much the same settings as I used in the OS with ASUS' 5-Way tool. Again no real surprises here. It just works and is easy for the novice to just push and play. If all that is too much to handle, then you could opt for one of the presets in the Extreme Tweaker Overclocking preset section of the BIOS that offers up some really interesting bclock and DRAM options.

Last but not least, you can manually tune the system to get the most possible performance from your installed components. This, of course, takes time and patience when looking for the maximum clock speeds your combination of parts will run. Setting the presets and using ASUS' tools will get you close to what your parts will do, thanks to how well the auto algorithms are built. You can use these settings as a starting point to tweak from to get to your best combination. By setting the CPU voltage and system agent voltage to manual control, I was able to reach a clock speed of 4784MHz on the CPU cores while running the Cache ratio at 46 at the same 4784MHz on the cache ring bus. It did take a bit more voltage to get this combination stable using 1.375 on the cores and 1.25 for the system agent voltage. Upping the bclock also raised the clock speed of the memory to 2912MHz, further helping performance along. This result was achieved in about an hour of tweaking with many of the voltage and system options left on auto. Given the ease of overclocking with a bit more time tweaking voltages I am confident that the overclock could be run at lower voltages.

Overall, pretty stout results from the Maximus VIII Gene.
