ASRock are not afraid of the legacy connections.  Not merely content on having both a floppy drive header and an IDE connector on the Fatal1ty Z77 Professional, they have also put a floppy header on the Z77 Extreme6.  There is reason for this, given that industrial equipment can cost $millions and a shiny new PC to process the data costs a lot less, even if they can only communicate via Floppy.  Today we are looking at the performance and package that comes with the Z77 Extreme6, and see if it holds up with its price tag against the vast array of Z77 motherboards currently on the market.

ASRock Z77 Extreme6 Overview

Performance is an odd test on a motherboard for the most part.  Every major facet of the motherboard is often in the control of something else - the CPU takes care of computation, the RAM looks after local data management, the chipset for IO, and audio for audio.  The motherboard is merely the collection of controllers collated with design, with a vendor specific flair of aesthetics and software on top.  So why test the performance?

More often than not, in each of the circumstances listed above, the motherboard comes in as the second most important feature.  The routing between two components will determine the latency, or the decision to use one port per controller rather than two may influence throughput.  These differences do not show up significantly during testing (CPU tests, for example) unless the motherboard becomes the limiting factor in some regard.  This is why we try to test with the best CPU, the best memory, and so on.  However, areas such as the DPC Latency (how the CPU and chipset deal with requests) are governed by the BIOS, something that the motherboard directly influences.

Thus, if a motherboard happened to perform near the bottom in the majority of the tests is quite alarming - somehow, the board has a flaw at some level.  What if the difference between the board and the second from bottom board was very slight every time, coming in at less than 1%?  How would we analyze such a product?  Would it be bad?

Unfortunately, this is where the Z77 Extreme6 fits in many of our tests.  It lacks the MultiCore Enhancement that both ASUS and Gigabyte apply to their boards for extra MHz at full loading, as well as long-term stability with my standard G.Skill DDR3-2400 testing kit.

This is not a concern if you run an overclock though, as the Z77 Extreme6 board overclocks the CPU quite well, reaching 4.7 GHz on our test chip with 1.175 volts in the BIOS and only 82ºC during OCCT.

Software wise, ASRock has paired the Extreme6 with their normal feature set plus a couple of bonuses for Z77 - namely their Online Management Guard facility and 'Dehumidifier Function'.  These two lack significant substance by being only BIOS based utilities though - ideally, a software implementation would be preferred.

For the price, we get ASRock's great little USB 3.0 bracket in the box, as well as a complete set of video outputs on the IO.  As a sneaky little addition as well, users can put in three AMD GPUs for 3-way CFX, if you do not mind the third card limited to x4 PCIe 2.0 coming from the chipset (analyzed later in the review).  This does away with the need for a PLX PXE 8747 chip on board, which would have increased the price by another $30 or so.

The ASRock Z77 Extreme6 is a capable motherboard for most usage scenarios.  Just add some nice DDR3-2133 memory and apply a CPU overclock.  However, it lacks some substance and a spark over other major motherboard manufacturers.

Visual Inspection

With the Z77 Extreme6, compared to the Z77 Extreme4, there are a significant number of changes, both visual and in terms of features.  For a start, the heatsink design is more pronounced, using something similar to their X79 range in terms of black and gold ridged and edged surfaces.

Onboard is also an mSATA port, right in the middle between the first PCIe slot and the PCI slot.  Above the PCIe slots is a 4-pin molex power connector to provide extra power to the PCIe slots, although I am kind of getting tired of seeing it put in this location.  If anything, it should be at the bottom end or beside the 24-pin power connector, as having it above the PCIe slots just means that there will be cables all over the place.

One other less obvious change to the Z77 Extreme4 is that there is a Floppy drive header on board.  Yes, you heard me right – floppy drive!  It seems odd now to include this legacy connection.  It still has a place in industrial concepts (where a machine uses floppy drives and costs 1000x more than the PC processing its data), but not particularly on a higher end product which may be geared towards gaming and overclocking.  As ASRock seem to be the only manufacturer pursuing this path on their consumer line, then it creates a niche just for them.

In terms of fan headers on board, we have one three-pin beside the 8-pin 12V power connector, two CPU headers (one 4-pin, one 3-pin) just to the right of the top heatsink, two chassis three-pin headers beside the molex connector, and another 4-pin chassis header on the bottom of the board.  On the right hand side, the USB 3.0 connector has been placed beneath the 24-pin ATX power connector, followed by the SATA ports.  Like the Extreme4, we have the PCH SATA ports (two SATA 6 Gbps and four SATA 3 Gbps) and two extra SATA 6 Gbps from an ASMedia ASM1061 controller.

Around the larger chipset heatsink, we have power/reset buttons and a two digit debug display, both of which I personally like to see as a reviewer (makes my job a bit easier) but also helps overclockers. On the south side of the board, apart from that floppy connector I mentioned, we have a COM port, front panel audio, and an array of USB 2.0 headers.

PCIe layout is similar to the Z77 Extreme4, with a PCIe x1, PCIe 3.0 x16/x8, an mSATA connector, PCI, PCIe 3.0 x8, PCI, and a PCI 2.0 x4.  This allows a user to use a dual GPU setup, and still have access to a PCIe x1 and x4.

Aside from the bowed picture from ASRock, we have something similar to the Extreme4 for the IO back panel, though this time with a DisplayPort output.  From left to right, we have a combination PS/2 port, two USB 3.0 ports (blue), a D-Sub port, DVI-D, DisplayPort, HDMI, a ClearCMOS button, two USB 2.0 (red), an IEEE1394 port, eSATA, gigabit Ethernet, two more USB 3.0 (blue), and audio outputs including an optical SPDIF.

    I feel like for the majority of people IDE is way more useful than floppy. If ASRock is gonna put one on the board, they may as well include both. I still have a handful of IDE drives laying around, which is useful for troubleshooting, or for use in a secondary rig. Reply

    If I really wanted a floppy drive I would buy an external USB one for 20 USD. Seems pointless to put it on a motherboard. Reply

    Agreed, I still need to use floppy disks at work and it's no problem with new machines as a USB floppy disk drive appears to work as well as an internal drive as I've had no issues with it. Even then I don't really get this board, I could certainly see making a legacy Z77 board with a couple of serial ports, PS/2 ports, PCI and IDE ports with the rest of the board very basic would be handy for legacy enterprise use but this board is nothing like that, it seems a fairly fancy motherboard with a floppy connector strangely added.

    An IDE port which be handy as there are times I'm still working with IDE drives and keep some of the older P4 machines which had both sata and ide connectors for that use.

    Agree have not used a floppy for at least 5 years, and have not build one in my PCs for even longer, still have a USB floppy, that i used literly just once, and properly never again.

    Just keeping it to show the grand kids in +20y or so, "look that's what gramps use to use to install DOS and Win 3.1!"

    It is an issue of compatibility. Floppies are needed for ancient software you cannot replace for some reason, and such software typically does not play well with USB floppy drives. Reply

    Just built my new gaming rig using this board which I picked up from the Egg for less than $160.

    I am happy with the board layout as it was easy to connect all my devices.
    The BIOS was super easy to navigate and understand and my internet BIOS update worked which was pretty cool being able to update BIOS like that.

    The build has only been running about 2 weeks and I am just running everything stock now making sure all components are stable. In another week or two I will try out overclocking.

    I did have problems with the board recognizing my RAM. I put 16GB of cheap Team Xtreem Dark Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 in the board and it kept thinking it was 1333. I had to go in and force the board to think the RAM was 1600.

    So far I get an occasional BSOD and it is either related to my RAM or my SSD (OCZ, I should have known better).

    Dude, that's not a problem, that's exactly the way memory is supposed to work. The JEDEC standards call for 1333 as a/the default setting when first installing memory so it'll work in any motherboard, regardless of rated speed.

    Then, to achieve the rated speed spec of the memory, one HAS to enter the BIOS and set it. The motherboard won't do that natively.

    Ok thanks for the clarification!

    After reading this review I am now a little bummed about the middle/lower performance of this board compared to its competitors.

    In all reality such a small difference in performance though is not my primary concern.

    I think I will see much more real world benefit from the XFast USB included with this board as it seems to make a substantial impact and I do quite a lot of USB transfers (pictures, video, files).

    Also nice to see this board is a good overclocker.

    I still wouldn't pass over the OCZ SSD as a problem. Both of mine eventually failed causing BSOD's. My Agility II didn't even last two weeks before disappearing into never-ever-land, never detected again, that is.

    Stick with Intel, Crucial or some other well known memory manufacture. Plextor is up and coming, too, but I still think if one is to go Sandforce, Intel 330 or 520 is your best bet.
