ASUS Maximus VIII Extreme BIOS

A large portion of this page will be identical to the Maximus VIII Impact review, updated for specific M8E features.

For users well accustomed to BIOS layout, it makes sense when a company uses the same basic libraries throughout their product stack. It makes sense for time and development, and there can be some leeway in customization for different types of products. So this is what I mean when I say that users who are familiar with ASUS’ main line of motherboards (the -Pro, the -A, the –Deluxe and other) will also understand what goes on with ROG. There are differences, and the first two to notice are the color scheme moving red but also that the BIOS enters straight into advanced mode, bypassing EZ mode.

But let us step back a bit, and move to EZ mode. For users who want to deal only in EZ mode, there is a setting which forces it as the default BIOS entry point.

Similar to other EZ modes we have seen from ASUS, this one gives details on the motherboard name, the BIOS version, the CPU installed, the speed of the CPU, the amount of memory installed, a graph of CPU temperature over time (useful if you’ve forgot to plug in the CPU fan… oops), the CPU voltage, the motherboard chipset temperature the speed the memory is running at, a per-DRAM slot label of what memory is installed, a per-SATA port label of what drives are installed, a quick button for XMP, a quick button for RST, a per-fan rundown of fan speeds, a diagram of the fan power control for the CPU fan, a quick button to customize the fan profiles, an EZ system tuning list for quick updating, and a boot priority list. Pretty much 90% of what you want a motherboard for, especially if you are the family computer guy fixing it.

Pressing F11 brings up the EZ Tuning Wizard to help users get some basic overclocking and RAID controls.

The EZ Wizard asks a couple of questions, such as what the system is used for (gaming or daily tasks/media consumption), what cooling is installed (stock cooler, tower cooler, liquid cooling, unknown), and then uses a lookup table and attempts to apply a sufficient overclock. It beats many ‘set it and see’ overclocking tools on other motherboards purely on user experience, even if results are similar.

Here for example I chose Daily Computing with a Stock Cooler, and it offered a 12% overclock for the i7-6700K (moving from 4.0 GHz to 4.5 GHz) and no change in the DRAM (DDR4-2133), then asked to enable it.

For the EZ RAID option, this makes the task of implementing RST on Intel configured RAID ports easier by providing a step-by-step guide.

Also on the EZ Mode page we have access to quick fan controls under Q-Fan:

The system will allow each fan to be configured either by PWM or DC controls where possible, and offers four presets (standard, silent, turbo, full speed) as well as manual control of a multi-point fan gradient. On the left hand side is the ‘Optimize All’ option, which provides per-fan tuning.

Moving back into Advanced Mode, and similar to previous motherboards ASUS is offering a My Favorites menu to allow users who have specific settings they want to tweak (typically overclockers), then options can be added here. For the Z170 platform, ASUS is now pre-filling the My Favorites menu with a number of options they feel are best suited for overclocking, such as core ratios, base frequency, DRAM multiplier, voltages and power options.

For the main glut of overclocking options though, the Extreme Tweaker menu has them all.

A wider range of CPU overclocking options are exposed on this first set of screens, with additional menu options for DRAM, power management and ‘extreme tweaking’. For users with the LN2 header enabled, more obscure options are also offered. However, the first option at the top is relatively interesting as a set of overclocking presets:

The majority of these are for extreme overclockers, but the Gamers’ OC profile is one we have tested in the OC section (along with the TPU options). The Gamers’ OC gives a 48/47/46/45 multiplier overclock with 1.425 volts set in the BIOS with LLC at Level 7. On our test bed with our #2 CPU, this passed our tests.

Similarly in the DRAM section, we also get a list of presets for extreme overclocking:

Most of these require knowledge into the memory you have, and are typically used by those close to ASUS’ in-house overclocking team.

Moving away from overclocking, and the Advanced menu holds most of the typical motherboard options for enabling/disabling controllers, organizing storage controls, C-states and USB configuration. I think the best bit about this is the SMART information screen.

Similar to OS tools to read SMART data, here we get information about power-on hours, power cycles and drive temperature. This sort of information tool is slowly moving into BIOSes of all the manufacturers, which is a good thing to see.

A menu for the Thunderbolt controller is also here, including Boot and Wake support.

Next up in the BIOS is the monitoring tools, which also doubles as the place for manual fan controls without the graph.

As the Impact has several additional temperature sensor headers onboard for additional thermistors, these can be added and configures here as well.

The Q-Fan control in text looks similar to other fan control software, and allows for separate fan header adjustment in DC or PWM mode.

Boot override and CSM controls are found in the Boot Menu, which also has the option for Above 4G Decoding if anyone wants to pair the motherboard with a MIC.

The last set of features for the BIOS are in the Tool menu.

ASUS has updated its EZ Flash tool to generation 3, allowing it to also probe an online server for an updated BIOS version, which is similar to what ASRock does. Secure Erase still features in the ROG BIOSes, as well as overclocking profiles, SPD information and GPU information. The thing missing from ASUS’ repertoire is a Board Explorer mode, similar to what ASRock and MSI have, which shows a diagram of the motherboard and what is installed in each port. As a method of showing if certain DRAM modules are not detected, or SATA drives not found, it provides a good user experience for most users (though one could argue that the various lists around the BIOS already do this, though they are not currently in one place).

    At that price point you really should be considering an X99-platform system. You're scraping the bottom of the barrel when it comes to diminishing returns. Reply

    This board does make sense for people who need a set of high end features that precludes any other boards, but that's few and far between. Reply

    Lot of talking up the gigabyte 4 way SLI, which was never even tested... As a reviewer wouldn't you wonder if it even works? Curious about the performance? Isn't that the whole reason for this website? To see how the latest and greatest tech performs? Anyways 500 bucks. Nah. Reply

    That is the whole point. ASUS makes this motherboard for the few and far between. Reply

    I was thinking that same thing. Why are motherboards going up so much in cost when the Processors have taken over most if not all of what used to be the Northbridge functions?

    If anything the motherboards should be worth less than they were before because for the most part, they aren't providing as much functionality. Granted, some have better voltage control and over-clocking capability, but that shouldn't add much to the cost comparatively. And this isn't the enthusiast lineup either. Not sure what these companies expect.

    You don't want to see the BOM of a $500 non server board. Reply

    your paying for the software on most of this high dollar hardware stuff. i know you are probably no interested in that stuff, but asus see's it differently. their magins will always be more than Asrock, so they have to differentiate somehow.

    Medical equipment is notoriously overpriced for what it is, but it uses custom software that nobody else makes, so they can get away with jacking up the price 2000% over the bill of materials.

    Medical business is a different animal. The standards and certifications they have to meet/pass means even the basic functions must be implemented in a different (more expensive) way. Things that are acceptable on a consumer product might be totally unacceptable on a medical one where a BSOD might actually involve a death ;).

    The NB functions were integrated into the CPU but then again motherboards didn't always have 2 NICs, WiFi, tricked up audio, bundled OC panels, etc. And don't forget about the 80/20 rule. You get 80% or results with 20% of the cost but then hang on to your sit because the cherry on top comes at a price. Optimizing the board layout and traces costs and if you want it you'll have to dish out the $500. It's always been the same, the closer you get to the top the quicker the costs pile up.

    I for one would never buy ROG again. Half of the stuff it offers is just wasted on me and I considered most features to be overkill and wasteful. I realized that after I started using (or not using) them. But then again there's always a market for this so why not? :)

    If you want the best quality product, then you will pay for it. That is true of any product. The best ones generally take more work to create. It is not simply the cost of the goods to create it. The labor costs can be very high. If you are satisfied with lower quality, then so be it. But there are some who simply want the best and are willing to pay for it. A $500 motherboard is nothing compared to the $25,000+ cost of a high end PC which may include a $2000 CPU, $1200 GPU, $1000 SSD, $8000 data storage system, $5000 professional monitor, etc. Reply

    The processors that work with Z170 have a newer architecture and better performance per-core, while X99 can support processors with more cores (and tons of memory), but generally less per-core performance.

    It depends on what you need. Gaming, for example, still has trouble scaling even to four cores and can benefit quite a bit from more per-core performance. That said, spending $500 on a motherboard (X99 or Z170) is something I'll never understand.
