Review: MAXIMUS VI Impact

The Maximus VI Impact (M6I) is ASUS’ first Republic of Gamers (ROG) mini-ITX motherboard (mobo) based on Z87 chipset. Offering strong performance with pure stability, impressive power delivery efficiency and state-of-the art thermal solution, the M6I fits in mini-ITX cases while retaining ROG’s gold – being an overclocking champion more flexible than ever. Recently, I had opportunity to test the M6I and now I am sharing the overclocking results to your attention. Let’s see what this little monster has to offer.

MAXIMUS VI Impact - Spec


MAXIMUS VI Impact - Retail Packaging
Like other ROG mobos, the M6I is packed in a red box. Not too big, not too small. Just about the size of the tiny board.

MAXIMUS VI Impact - Front View
With a black and red color scheme, the M6I houses an LGA1150 socket and supports Intel 4th Generation Core i7, i5 & i3/ Pentium/ Celeron processors. The mobo is a mini-ITX with a dimension of (17.0 x 17.0) cm and comes with four SATA3 ports to provide adequate storage. There are two RAM slots supporting up to 16GB of of DDR3 Dual Channel as fast as 3000 MHz+.

The M6I is powered by a unique Impact Power consisting Digital 8 Phase Power Design (8 Phase VCCIN) with ASUS CPU Power Utility & FIVR Control. Additionally, there are also 2 Phase Digital Power Design with Asus DRAM Power Utility to deliver sufficient power for extreme memory overclocking.

MAXIMUS VI Impact - SupremeFX Impact
There is one mini-PCIe II connector sitting between the I/O Panel and PCIe slot, providing Wi-Fi and Bluetooth connectivity and even supporting a new M.2(NGFF) Solid State Drive (SSD). Due to limited space of this tiny board, ASUS decided to put the SupremeFX Impact audio as a daughter PCB, to provide high quality sound output. Also spotted, a PCIe 3.0 16x slot which supports the latest graphics card.

The rear I/O panel packs one DisplayPort (DP), one HDMI, one Optical S/PDIF out, one Clear CMOS button, one DirectKey button, one MemOK! button, a Q-Code LED, four USB 2.0 ports (one port can be switched to ROG Connect), four USB 3.0 ports (blue), one eSATA port, one LAN (RJ45) port, as well as three audio jacks from the SupremeFX module.

MAXIMUS VI Impact - Back View
The back side of the board is very simple, a CPU socket backplate is used to provide retention to the CPU cooler on the top of the board.

The CMOS battery is placed like this to save the space. What a brilliant idea by ASUS designers.

Software & Tools

MAXIMUS VI Impact - AiSuite III

  • AI Suite III – An OC tweaking application for overclocking in the OS.
  • MemTweakIt – Display the memory timings in the OS. Unfortunately, due to Intel’s lockdown it is unable to adjust timings real-time in the OS for now.

Stability Tests

Basically, Haswell was born hot due to inefficient heat conductivity between the internal heat spreader (IHS) and the die. Under water, the 4770K is overclocked to 4.5GHz HyperThreading (HT) @ 1.25v passed LinX without an error in 20 loops. One of the CPU cores hit 97C during loading but it’s still lower than TJmax of 100C. At the same time, the memory is overclocked to 2933MHz 12-14-14-25-2T @ 1.65v on air.

LinX 0.6.4 w/ AVX:
LinX 0.6.4

Benchmark Tests

The 4770K is overclocked to 4.7GHz (4 cores/8 threads) for benchmarks. Meanwhile, the HD7970 is overclocked to 1300MHz core/7000MHz mem @ 1.3v/1.7v.

Thoughts & Verdicts

ROG MAXIMUS VI Impact is really a strong motherboard for extreme overclocking. If you are looking for a high end mini-ITX board, then the M6I is a perfect choice for you. Overclocking on the 4770K is as good as any other larger motherboard out there. Memory overclocking slightly better than its elder brother, the Maximus VI Extreme (M6E), it is able to push my Hynix-CFR based RAM kit to 3250MHz easily at the very first boot. The UEFI BIOS works flawlessly with all of the memory kits that I have used. It is amazing on how ASUS crammed the tiny board with so many high quality components and features. The M6I is now available locally for RM988 (SRP), which is slightly more expensive than the mATX based Maximus VI Gene (M6G).

I would like to thank ASUS Malaysia especially Sanko for sending me the motherboard for a quick review.
