ASUS ROG Maximus XI Gene microATX Motherboard Review


ASUS ROG Maximus XI Gene microATX Motherboard Review -

ASUS has skipped a few generations before, not releasing an ROG Gene model but regardless, most Gene models are cutback versions of the Formula in some way. When the Hero line was introduced, the Formula models stepped into a more top-end position and the Gene served as a standalone representation of ROG’s vision of a compact board with top-end features. With the Z390 release, ASUS has stepped away from the dual PCIe x16 slot format for mATX and has made other various changes to offer what seems to be a platform for maximum performance with maximum high-speed storage potential.

The new ASUS ROG MAXIMUS XI GENE is a big change in layout from traditional micro ATX boards. But is ASUS limiting its user-base by changing things that already work. Read on to find out more about the MAXIMUS XI GENE.

About Intel Z390

It was already announced that Intel would be releasing a Z390 chipset a bit further in the year with the announcement of Z370 back in early 2018. That announcement materializes late in 2018 with the launch of the Intel Z390. Usually a processor would be the prelude to a new chipset but in this case, with the rumor already floating around that an 8-core Intel MSDT part would be released, it was already expected.

Intel Z390 Chipset Block Diagram

Not much has changed from Z390 to Z370. The new 9th-gen processors themselves work fine on Z370 chipset boards although Intel has been very adamant in utilizing the new Z390 boards with 8-core parts due to revisions on standards about how board makers should configure their VRMs.

In terms of changes, there’s only a few to note which includes Intel WIFI-AC having been baked directly into the board, the increase in USB3.1 Gen2 ports to 6. PCI-e lanes and HSIO config remains the same from last generation.

Coffee Lake Refreshed

The 9th-generation Intel Core processors mark the debut of the Core i9 in the mainstream market, previously only being made available in HEDT platform. This also sees Intel’s first 8-core offering for mainstream. One that would see prices skyrocket for their top parts. Factor in the current, ongoing supply issues that Intel has and its been a difficult time for the company and customers alike in terms of availability and pricing.

Going back to the processors themselves, Intel has announced three launch models: the Core i9-9900K, Core i7-9700K and the Core i5-9600K. Other SKUs have seen been announced including models without IGPs. Besides core count, one of the main changes that the 9th-gen Core processsors will is the total lack of Hyperthreading. Only the Core i9-9900K will have Hyperthreading amongst all currently announced models alongside its non-IGP counterpart.

As with the previous Coffee Lake release, the parts are forged in the 14nm fab process.

Packaging & Content

ASUS ROG Maximus XI Gene microATX Motherboard Review -
ASUS ROG Maximus XI Gene microATX Motherboard Review -

ASUS has been subtly tweaking its packaging over the last generations of motherboards and this time around, the change is a bit more defined yet still subtle. The new ROG motherboard packaging now don a more distinct black styling with abstract panel lines adorning the main sides. The main cover has holographic prints in bold for the model names with minimal prints on the rest of the front.

The side are now a brighter shade of red, a truer red than what we’ve been used to seeing since the early Maximus or Rampage releases. The narrow sides now have a bright red print with the eye logo of ROG printed on 1 side similar to Jordan brand packaging style.

The Maximus XI Gene’s packaging is thinner but wider than the Maximus XI Hero and Extreme. This is due to ASUS moving all accessories to one compartment to the side of the board packaging and putting the wider paper inserts on the bottom.

Closer Look

The entire MAXIMUS XI portfolio will share a new darker theme than previous ROG generations. This makes them even more neutral making them easy to blend with any themed builds. ASUS’ excellent build quality is evident when you first hold these boards and the MAXIMUS XI GENE, despite its size is a hefty board.

The board features 12-phase power delivery design to provide stable power to the CPU. The design is capable enough to handle extreme overclocking and heatsinks used to cool the VRM area are denser to handle the larger VRM area.

And here comes one of the major changes in this motherboard with the use of only two DIMM slots. As you can see, ASUS has opted to utilize the space for a M.2 slot and a DIMM_2 slot. DIMM_2 is ASUS’ proprietary mounting for their M.2 risers which debut with the Maximus IX series. The motherboard extends a bit than most mATX boards, utilizing the maximum width of the ATX standard meaning the board is literally an ATX board but with mATX height. The layout on this motherboard is impeccable and everything looks square in place including the onboard buttons and debug LED. The ATX power and USB3.0 front panel connector and USB3.1 connector look flush and clean and don’t look like they were crammed in their places for no reason.

A large heatsink spans from the top of the board in-between the DIMM slots and DIMM_2 slot. This screws into place and houses a single M.2 SSD.

As mentioned, ASUS built this board for extreme performance and while we feel it doesn’t need it, ASUS puts in two 8-pin ATX-EPS power connector on the motherboard for extreme situations.

Another notable shift in design with the Maximus XI Gene is the decision to angle all connectors. Most, if not all, bottom edge connectors on this motherboard or angled downwards allowing for a cleaner look but based on experience, planning is required before finalizing wiring as we’ve had some very complicated situations in which we need to reconnect wires in an mATX case but with the cables already flush to chassis floor, it gets tough disconnecting and connecting them again. Still, its a nice idea and one that other motherboard brands should consider.

Notice that the motherboard pushes the first x16 slot to the 2nd space which has been the trend recently, relegating the first PCIe slot to x1 duties. This allows board makers to have M.2 slots just below the CPU socket. In an mATX situation, this arrangement removes a possibility of a 2nd x16 slot which a board of this level is capable of handling. Previous Gene models supported multi-GPU configurations but with the Maximus XI GENE, ASUS has decided to drop multi-GPU support altogether, instead opting for a single PCIe x16 slot and a single x1 slot.

At the back we have the BIOS flashback and reset buttons. We also have a legacy PS/2 port, USB2.0 ports, 4x USB3.0 ports (one of which used for the BIOS flashback feature, denoted by the square outline and BIOS label on the lower pair), USB3.1 Gen2 Type-C and Type-A ports, the WIFI connectors and the audio connectors. For video, we have a single HDMI port for output display from the IGP.

BIOS Walkthrough

ASUS ROG Maximus XI Gene microATX Motherboard Review -

ASUS still has their familiar UEFI BIOS interface with the new Z390 motherboards. Most of these boards will share the same menu options with higher models like the Maximus XI Extreme having more menu options for extreme overclocking and tweaking. The ASUS Maximus XI Hero, Gene, etc. mostly share similar menu options.

The UEFI interface has been a mainstay for ASUS for a few generations now and we’ve praised it for being a simple yet rich at the same time. The interface is simple to navigate and offers easy-to-use dropdown menus to change values. Besides tweaking options, ASUS also integrates rich fan controls as well as voltage and temp monitoring. There’s also profile management, DRAM and PCIe viewers to check system hardware. ASUS integrates the option to update the BIOS online as well as via local storage with their interface and has been a great tool to work with.

ASUS has a BIOS flashback feature which allows users to reinstall a fresh BIOS copy in the event of an issue.

ASUS also integrates AI overclocking with their latest motherboards allowing the BIOS to gauge processor potential. In the screenshot below you’ll on the lower right the Cooler points and Silicon quality rating of the system. Intel has since voiced their concern over this and has requested ASUS to remove silicon quality. Newer BIOS will not have silicon quality in their prediction panel.

All tests are performed in an open bench with ambient room temperature kept at 28*C.

Motherboards are updated to the latest BIOS during time of testing kept at their out-of-box settings aside from XMP frequencies when running stock benchmarks.

As many already know, most motherboards will have varying frequency multipliers and this may affect performance overall. As this is part of their out of the box configuration we see it fit to use them as is. All data presented here in are with the default motherboard settings for stock performance. Overclocked performance will be indicated where needed. For non-Z series motherboards, all benchmarks are performed on DDR4-2133 default settings.

As always, we’ll let the numbers do the talking.

Best Practices

  • Same thermal paste and same application method used on all cooler mounting. A pre-benchmark stress test is performed to let the TIM settle. We use Noctua NT-H1 for all our testing.
  • A fresh install of Windows 10 Pro is used for every sample testing. The OS image contains all benchmarks and games. Drivers are installed after image is installed.
  • An average of 3 benchmark runs is used for test sampling.

Temperature & Power Draw

In this test we’ll measure how much manufacturer-set BIOS settings affect temperature and power draw. As we’re dealing with pre-launch samples, more mature BIOS may change these over time.


Power Draw

wpDataChart with provided ID not found!

We really don’t put too much stock on individual component temperatures as they will vary depending on usage and we do not benchmark using extreme loads anymore as they’re not reflective of real world applications. To stress the CPU, we use a 20-minute run of AIDA64 stress test. We recorded the peak CPU temps and cross-match HWINFO and AIDA64 readings. For power readings, we measure the peak system draw.

Value & Conclusion

ASUS ROG Maximus XI Gene microATX Motherboard Review -
ASUS ROG Maximus XI Gene microATX Motherboard Review

microATX and miniITX may be more accessible nowadays but both of which have been relegated to the compact system designation but as with recent years have shown us, compact system are more than capable of performing like their full-sized counterparts. That being said, the catch is that these mATX boards are configured similar to their full ATX brothers and with the ASUS MAXIMUS XI GENE, having to drop a pair of memory slots and lose dual-GPU capabilities meant this new platform will offer pretty much the same performance as an equivalent 2-stick, single GPU system. The catch is, well, obviously you’re stuck with only two DIMM slots and a single GPU which begs the question why ASUS went this direction. What you gain though is high-speed channels for our M.2 storage and if you’re looking to expand, you can pop-in a riser in that PCie x1 slot for more high-speed storage. This could make for a compact, content creation rig that heavily uses high-speed storage IO like 4K videos but then with that kind of usage you’re limited to 2 sticks of memory which at this point in time in December 2018 and early 2019, is limited to a maximum of 16GB per stick.

But have no fear, ASUS to the rescue as they’ve partnered up with G.skill and ZADAK 511 to offer Double Capacity memories which are only compatible with the ASUS MAXIMUS XI GENE and XI APEX. This solves the problem of memory size until 32GB and 64GB sticks become standard. We’ve yet to test Double Capacity memory so we’re still unsure about its performance.

Regardless, the ASUS MAXIMUS XI GENE performs like a champ, showing numbers closer to the MAXIMUS XI Extreme than the Hero. This reflects our earlier expectations from boards with simpler feature sets like this one. In terms of features, there’s plenty here to make sure that compact builders don’t feel left out with the board delivering same-level performance and tweaking features like its full ATX brothers.
