ASRock Z97 Extreme9 Software And Firmware

Z97 Extreme9 Software

ASRock’s A-Tuning provides Windows users a wide range of software-based overclocking options. Pre-defined profiles include “Turbo 20” and “Turbo 30”, which, rather than provide our Core i7-4790K with 20 and 30% overclocks, instead take it to 4.5GHz at 1.27V and 4.6GHz at 1.32V. Both adjustments occur at the firmware level, requiring a reboot to activate.

“Optimized CPU OC Setting” options for our Core i7-4790K include 4.5, 4.6 and 4.7GHz at 1.25, 1.30 and 1.40V maximum. Though all of these settings were initially stable, the highest 4.7GHz mode eventually caused thermal throttling.

ASRock “Lifestyle” apps include OMG connection control, a power LED disabling utility, a fan tuning utility, a thermal cycling utility called “Dehumidifier”, a tool that turns any USB thumb drive into a login key, an OC profile utility, HDD Saver to power-cycle hard drives that might otherwise seize up after months of inactivity and DISK health reporting.

ASRock OC Tweaker includes the full range of CPU BCLK, CPU multiplier and CPU/DRAM/PCH voltage adjustments available from firmware.

A-Tuning’s status monitor still offers a pop-up screen to display the locations of detected hardware. This is particularly useful when diagnosing a failed component, which might have dropped out of detection due to excessive overclocking.

Z97 Extreme9 Firmware

The top of ASRock’s OC Tweaker menu includes several factory-configured overclocks, which the company believes will work with most unlocked processors. These include Turbo 4.5GHz at 1.23V CPU core, Turbo 4.6GHz at 1.30V, and Turbo 4.7GHz at 1.40V. None of them were stable with our CPU sample, though.

Indeed, our Core i7-4790K is no better at overclocking than the Core i7-4770K that preceded it. The new internal thermal material allows it to take more voltage before throttling, but its less-perfect core also needs more voltage to reach similarly-high frequencies. This CPU doesn't even reach the same 4.6GHz of our previous processor, though the Z97 Extreme9 got us close to that level with a 4.54GHz overclock at 1.28V. The additional voltage required for a 4.6GHz push eventually forces thermal throttling.

We’ve grown to expect unreported extra DIMM voltage from every board on the market, and a 1.625V setting that produces our desired 1.65V level isn’t too far off compared to ASRock’s competitors.

The Z97 Extreme9 had no trouble topping our memory’s DDR3-2800 data rate, even with all four modules installed. Primary, secondary and tertiary timings are all individually selectable to enable even better overclocks or lower response times.

The software-controllable HDD Saver feature, which occasionally powers-up idle drives, finds its firmware basis in the Z97 Extreme9’s UEFI.  Further advancements can be found in an assortment of Web-based features, such as server-to-thumb drive downloads for drivers and an email-based tech service utility. Frequently needed by overclockers, ASRock Instant Flash firmware updater and three “User Profiles” for overclocking configuration storage are accessible from the same “Tools” menu.

    Damn, nice boards but really expensive. A pity about the i7 4790k not performing well, as I really wanted to see which board was best at OC'ing

    Seems like somewhat of a shame to test boards with a PCIE switch using only a single GPU. How many enthusiasts who spend in the neighborhood of $300 on a motherboard would settle for a single-GPU setup?

    This needs a follow-up with x16x16 PEX vs x8x8 native vs x16x16 LGA2011 and, hopefully, x8x8x8x8 PEX vs x16x8x8x8 native on LGA2011.

    On-board wifi is simply a waste of space and power (and probably available pcie bandwidth) - even for mITX mobos. Wireless specifications change too frequently to get locked in to whatever is on your mobo. USB dongles are easier to upgrade/replace and allow more flexibility with respect to antenna placement.

    If you really can afford 3 GPUs, you should really be starting with X99. For Z97, full-size ATX boards are kind of a waste due to the limit on available PCIe lanes, unless you want just 1 GPU and a bunch of other 1-2-lane expansion boards. I would have preferred seeing what you can get in a uATX (or possibly mITX) solution for the same budget in a package that's arguably a better fit to cater to the SLI/CF crowd and easier to fit in a case.

    Love to see things at their full potential, but can we include a i5-4690k for comparison? Many people don't need what the i7 offers and would love to see how the i5 overclocks and performs on these motherboards.
  • SessouXFX
    How do they measure up to the Asus Z97 Deluxe?
  • rolli59
    Really when it comes down to that class of boards and money is no issue, the question is; is your color theme, red, yellow or blue?
  • SessouXFX
    Anodized Gold. :P

    That one MSI board...I hope that price isn't accurate, that they're currently out of stock or something else is going on, as in, it's being shipped from S. Korea...
  • fl-gators-fan
    Very nice to see the Gigabyte Gaming GT coming out ahead, as that's the board I'm using. I've had it for about 2 months with the I7-4790K and haven't even tried overclocking yet. The 4.0 GHz is plenty fast for all I do :)
  • Gurg
    So this indicates that for what it costs to try to dress a 4790k up, you will spend at least as much as a higher performing 5820k.

    While the motherboard and CPU may cost about the same, you also need to throw in an extra $100 for DDR4.

    Good article and read there Thomas! In person the MSI board does feel solid but you've gotta admit and wonder, do I need a full sized mobo merely for the add on widi card and sacrifice multi GPU loadout? Answer is no.

    Keep up the good work mate!

    5820k is clocked slower than 4790k and doesn't usually O/C to the same max frequency. So this is primarily a gamer's option. And it uses cheaper RAM.

    I too would be interested in the Difference between these and the ASUS z97.

    I thought so too. Asus chose not to participate this time because it didn't believe its cheapest 3-way/4-way SLI board would stay within the price range, and it didn't want to put a board lacking this feature against samples such as Gigabyte's and ASRock's.

    BTW, I have to be VERY CAREFUL about what I reveal of these conversations. So, you're welcome :)

    BTW 2, new forum member and freelance technician Gordon_Foster89 assisted in the testing of these boards. Don't be afraid to hit him up with testing questions :)

    Thanks for that information and we understand that you can't talk too much about that
  • rush21hit
    I'd say the difference is negligible at best. It all goes back to the feature people want for their money. Depend on what you need, none is better than the other as far as I can see.

    That said, I for one, would choose whichever the cheapest and also has the longest replacement warranty, ignoring their feature altogether. Though they seem to be standardized nowadays, by 1 year 1:1 replace for faulty product and 2 years free service AFAIK. Regardless which you choose.

    I really want to upgrade to one of these and an i7 4930K, I really do. And the money is available also. But my wife would kill me first...
  • Zach_Tom
    I would rather see the Gigabyte GA-Z97X-Gaming-G1 Wifi Black edition or the standard edition
  • TechTanium
    i really want to see the MSI Z97- MPower Max AC performance as it is my dream board ;-) and msi normaly outperforms outher brands in stability and OCing

    "Since the hose side of the bridge only operates in x16 or x8 mode, total bandwidth drops to x8. Those eight lanes are still repeated to four slots, but “x16” mode for two or fewer cards only exists on the device side of the bridge whenever Ultra M.2 is utilized in PCIe mode."

    What does this mean? On the Asrock mobo if I run a x4 m.2 ssd in the ultra slot how many lanes will my 2 GPUs run 'at'? 16/16, 16/8, 8/8, or other? And if I only run one gpu will it run at 16 or 8?
  • Danra
    It is too bad that the LAN uses so many CPU cycles, I would prefer they use a Intel, that would make the Gigabyte nearly a perfect motherboard, even if the price were a little higher. I know manufacturers try to give customers the most bang for the buck, however, I think getting those wasted CPU cycles back is worth paying for.

    Awesome, you get your $700+ video card, plug it in and install a single PCIe x1 device and your video card slot drops to PCIe x8... I believe this is the first time that a socket 1150 or 1155 motherboard has 48 PCIe lanes available [thanks to the ExpressLane PLX PEX8747 chip].

    You can actually spend $1400 on two Nvidia GTX 980s and have full PCIe x16 bandwidth on both. I am a single video card user because I cannot afford to pay more than the price of a good computer build for the price of two GTX 980s, however, the PLX PEX8747 chip permits me to plug in some other PCIe x1 device.

    Should be "host" side.

    Anyway, if you install an x4 SSD the slots will get x8 bandwidth, x8/x8 bandwidth, and x8/x8/x8 bandwidth because the bridge is a repeater. That's the short story.

    The long story is that two of your cards will be detected as having x16 connections because that's how they'd connect to the bridge.Its as if you lived on a 2-lane street that opened up to two more turning lanes where it crossed a main road, then the google van drove by and took a snapshot of those four lanes and registered it as a 4-lane road.

    I had to correct a few of the locations in my neighborhood on Google Maps and more so on their van footage

    so if i have like 2xGTX 970 and a M.2 SSD,in the Asrock board my VGA bandwidth will be reduced to 8x8 plus a 4x lane for the M.2 SSD but in the Gigabyte Board that doesn't happen it will be 16x16 because Gigabyte has a regular M.2 slot right?and what if i added i added a sound card (Creative sound Blaster ZXR)aside form the M.2 in the Gigabyte?will that also decrease my VGA lanes to 8x8?

    The Gigabyte board has no M.2 slot, and you can use the middle PCIe 2.0 x1 slot for a PCIe sound card without worrying about the PCIe 3.0 lanes.
